In Depth: Google: 'We want to strip out operating system frustration'

<img src="http://cdn.mos.techradar.com//classifications/computing/software/operating-systems/images/Chrome_OS/chromestore-200-200.jpg"> We popped along to Google's London HQ this week to talk Chrome OS, Google's new low-resource Linux-based operating system for netbooks and notebooks. Chrome OS product marketing manager, Eli Lassman, took us through the features of the CR-48 prototype portable which TechRadar saw last week and gave us some background on the imminent launch of notebooks featuring Chrome OS. It's fair to say that the version of Chrome OS <a href="">we've seen on the CR-48</A> is not finished. The browser itself is slow, but the real problem is the apps – Chrome OS needs Google to make several of its apps support offline use in HTML5 and replace the functionality lost with the end of Google Gears – especially Google Docs. We had expected Google Docs to have launched its new offline capability by now, and Lassman confirmed the web giant is still working on this. As Chrome OS is ostensibly just a browser interface, Lassman was asked if the OS was too limited in terms of its interaction with the hardware. "The whole focus is on the cloud and the experience [is] better there," he explained. "There will be storage and you can download files onto the solid state drive itself, but the real focus is the cloud, that's where it really comes alive." The OS will also have its own media player – which doesn't currently work – as well as full USB storage support. Chrome OS apps will be available via the Chrome Web Store which is also used in the Google Chrome browser. So far there are 3,700 available. Chrome OS UK release date As for a Google Chrome OS release date, the first notebooks are due to hit during the summer months, though exactly when remains unclear. Precise Chrome OS launch dates would appear to be up to the launch partners. Initial units will come from Acer and Samsung, with 3G and Wi-Fi variants from each. As for pricing, ballpark figures point at between $250 and $600. If that means £199 Chrome OS machines, Google will be onto a winner, if it ends up being £299, that's dangerously into Windows netbook (and cheap notebook) territory. The CR-48 Chrome OS notebook we've had in the TechRadar office isn't a shipping unit, nor is it GSM-enabled – it's actually the same Verizon CDMA unit that has been previewed in the US since December. The unit will be supplied unlocked. <img alt="Google chrome os" src="http://mos.futurenet.com/techradar/classifications/computing/mobile-computing/notebooks-and-tablet-pcs/images/chrome-cr48/cr-4823-420-100.jpg" width="420"></IMG> In terms of actual retail outlets, we believe Google will aim high and the clout of Samsung and Acer should ensure we'll see Chrome OS laptops in standard retail outlets such as Currys and PC World. Chrome OS's real boon is speed. As Lassman explains. "From the time you enter your username and password from the time you get into Chrome OS you can be in your email in 10 to 15 seconds. "We've really focused on making sure everything is taken out of the way so you can get online as quickly as possible. That shows you who the target audience is, people who are already living in the cloud. We want to strip out what frustrates people about operating systems. "You can take your friend's computer and if you have a Google Account you can login, but you don't need to have a Google Account. "It takes seven seconds from switching on to get to the browser," continues Lassman. "The original goal was two or three seconds… they're working towards it, they've halved it in a relatively short space of time and it will only get better. <img alt="Google chrome os" src="http://mos.futurenet.com/techradar/classifications/computing/mobile-computing/notebooks-and-tablet-pcs/images/chrome-cr48/cr-481-420-100.jpg" width="420"></IMG> As with Android, Google aims to ensure a consistent experience across all Chrome OS netbooks with a hardware spec for manufacturers. "There is a guideline that we have for the OEMs. It's a reference for what we want to have, including the keyboard [layout], the trackpad and screen resolution." But is Chrome OS too restricted by the lack of availability of apps and is Chrome OS, the browser and the Chrome Web Store yet another closed ecosystem? "We're really trying to avoid the idea of a walled garden," counters Lassman. "We're trying to keep people on the web. The whole idea is that we're giving access to the web. The whole operating system is just based on bringing people online." "I think what this comes down to is that there's so much you can do on the web itself. When I'm on my computer I'm using a web browser 95 per cent of the time. So I wouldn't think of it as a closed system as we have the whole web. The apps are optimised… ultimately you get to use the whole web. " Apps on Android and Chrome OS Lassman also said it would be relatively simple to port apps between Chrome OS and Android due to the HTML5 standards used – and there's additional benefit from the Chrome Web Store's payment system. For developers using the Chrome Web Store in this way, Google charges developers a processing fee of 30 cents plus five per cent of the transaction amount. "For developers, having the payment built in gives them the incentive to design apps. Since you are basically building an advanced website, it's not the situation where you would have to rebuild." Chrome OS is a totally open source project unlike Android. Google is not releasing the source code for Android 3.0 Honeycomb in an attempt to attain a unified experience with all Honeycomb tablet devices. We'll be bringing you a full review of Chrome OS on TechRadar when we have a final unit.

What Operating System is the iPad Going to Run?

Many have waited a number of years for the Apple Tablet. Each announcement there was hope for the tablet and finally it has actually arrived. The iPad is here. One thing that many are focused on now is the operating system that it runs. Is it running a stripped down OSX or something else? Those who were hoping to have a small tablet computer that was like your OSX operating system might be a bit let down. The iPad is using a version of the iPhone's operating system. Essentially it's a giant iPhone or more correctly iPod Touch since there is no phone feature. While this is somewhat understandable there is one huge missing piece. The big problem is that there is no multithreading technology. This means that your $500+ tablet computer can only run one application at a time just like your iPhone. For some who enjoy multitasking while using a computer this is a big let down. Even the cheapest sub $200 netbooks running Linux can handle multiple applications at one time and that hardware is quite a bit less powerful than what the iPad has. One can hope though since this is the first version. The desire from customers for multitasking through multiple applications will surely push Apple to come with with a solution. If not, it's possible that someone will come up with a hack for the device. Jailbreaking the iPad won't have as much problems as it is when jailbreaking the iPhone because there is no chance of losing the phone capability.

History Of Operating System

Introduction 
Linux OS was first created by a student from the University of Helsinki in Finland. The author's name was Linus Torvalds and he had an interest that turned into a passion for Minix, a small Unix application which later evolved into a system that exceeded the standard Minix. He began working for the MINIX in 1991 and worked heavily until 1994 when the first version of the Linux kernal 1,0 released. Linux kernal This lays the foundation on which the Linux operating system formed. Hundreds of organizations and businesses currently engaged people and used for release versions of operating systems that use the Linux kernal.operating characteristics and adaptation of Linux have made Linux and Windows OS are excellent alternatives to other operating systems. IBM and other giant companies around the world support Linux and the current work, a decade after the original version. The operating system is embedded chip using a process called "integration" and increases the efficiency of appliances and devices. 
History of Linux 
Through the 1990's some technical Savy computer hobby stubborn people who are interested in desktop management systems developed. These systems, including GNOME and KDE applications running on Linux is available to everyone, regardless of the motivation of persons to use the system. Linus Torvalds was interested to learn the capabilities and features a 80386 processor for changing jobs. The application was originally called Freax first used by the operating system Minix. 
Both Freax Minix and plans seemed to sacrifice performance for academic research and study. Many computer specialists are now making assumptions that have changed since the early 90's. Mobility is now a common target for these specialists in the field of information and this is definitely not an academic requirement for the software. Various ports to IA-32, PowerPC, MIPS, Alpha, and ARM with supporting products made and sold to wholesalers and retailers, traders gave Linus an Alpha system where the tasks in the list of priorities Linus went to a very busy place. 
History of Windows 
Microsoft chairman was Bill Gates and Paul Allen shared the title until 1977, when Bill Gates became president and vice president Paul Allen. In 1978, the drives of the machines Tandy and Apple was 5.25 inches. First COMDEX computer show in Las Vegas introduced a chip 16-bit, and the manufacturers have introduced Intel 8086 chip. Al Gore comes up with the phrase "information highway." The same year, Apple cofounder Steve Wozniak developed the first programming language called Integer Basic, the language was quickly replaced by Microsoft Applesoft Basic. 
Also in 1978, there was a machine that had a comprehensive, independent design and was priced at less than $ 800, also known as the Commodore PET that was a personal electronic transactor. On 4/11/78 Microsoft announces third language product, the Microsoft COBOL-80. On November 1, 1978 after the introduction of third language, opened its first international sales office in Japan. The Microsoft representatives ASCII Microsoft, locatwed Tokyo, asits exclusive sales agent for the Far East. And finally, New Year's Eve of 1978, Microsoft announced that year end sales were over $ 1 million dollars. The next year, in April 1979, the Microsoft BASIC 8080 is the first microprocessor to win the ICP Million Dollar Award. The mainframes dominated by software on the server, the recognition for the PC computer reported the development and acceptance of industry. 
Both Gates and Allen returned home to Bellevue, Washington and announced plans to open offices in their hometown, and became the first microcomputer software company in the northwest. 
Technical details of both Linux and Windows operating systems 
An operating system takes care of all input and output are in a computer. Manages users, processes, memory management, printing, telecommunications, networks, etc. The operating system sends data to a disk, printer, monitor and other peripherals connected to the computer. A computer can not function without an operating system. The operating system tells the machine how to process instructions from input devices and software running on the computer. Therefore, each computer is built differently, or orders for production should be treated differently. In most cases, an operating system is a giant nest of programs, but instead a small system with programs running from the core or kernal. The computer's operating system the computer is so compact, these little programs that claim to be easier to rewrite parts of the system r packets rather than redesign an entire program. 
When first created operating systems were designed to help applications interact with the hardware. This is the same today, the importance of the OS has increased to the point where the operating system determines the computer. The operating system transmits a layer of abstraction between the user and the machine when they communicate. Users do not see the hardware, but the view through the operating system. This pumping can be used to hide certain elements of the material from the application and user. 
Applied Software is what is general, but especially for a single machine function. The software will run on any machine. Applications like this are SABRE, the reservation system for airlines, and defense systems. Computer Aided Software Engineering (CASE) Creating software is a costly and time consuming process. These programs will support and in some cases replace the engineer to create computer programs. CAD cam systems is the Computer Aided Design & computer aided manufacturing. The circuit board design in a computer program, the possibilities multiply. As premanufactured elements, load calculations, simulations of how a building will keep in earthquakes. 
In Linux there is a question that has been going back and forth for a while now, is dead SCSI for workstations? There have been many advances in SATA and the mainstream acceptance of 10K RPM Western Digital Raptor maybe that made SCSI too expensive for what is needed in a job. It is time to take a look at Linux. How does the Western Digital Raptor WD740GD over the last three Ultra320 SCSI drives: the Seagate Cheetah 10K.7, Seagate Cheetah 15K.3, and Seagate Cheetah 15K.4. This section covers the technology of audio disks, heat, size and performance. 
Lets take a look at the latest generation of Seagate 10K Cheetah line and 15K Cheetah line. It will also take an in depth look at the latest 10K SATA drive of the Western Digital 74GB WD740GD. Starting from the Western Digital Raptor, WD pushes this drive as a low cost of responding SCSI. On their website, they like to show off the drives 1.200.000 ώρες MTBF (mean time between failures), which matches the last MTBF generation of Seagate 15K.3 Cheetah is very close to the reliability of rating Cheetahs today. 
The prospectus or the prospectus of Linux, I would mention that the unit Cheetah is designed for "high performance around the clock use." Both the Cheetah and the Western Digital Raptor drives have the same amount of memory cache. When speaking of the actions an environment multi-tasking/multi-user, in favor of the tail is a technical advantage. All Ultra 320 SCSI drives support what is called Native Command Queuing, or NCQ. This technique is where all commands sent to the drive can to be queued and reordered by the most efficient order. This stops the car from having to seek services on a single side of the disc, then goes to the other side of the disc serve another request to return the next request .. While some of the SATA drives support NCQ, the Raptor does not. The Raptor is another form of the tail called the Tagged Command Queuing or TCQ. This method is not as effective as NCQ and requires the support of the motion and central controller. From what I was able to determine, TCQ support is sparse, even under Windows. 
The SATA drive is supported on the strength requirement by stating the use of fluid dynamic bearing their drivers. The fluid dynamic bearings replace ball bearings to reduce the car damage and drastically reduce operating noise. 
Microsoft Windows XP technology is easy to enjoy games, music, movies and beyond the film making and enhance digital photography. Direct X 9,0 technology drives high speed multimedia and various computer games. DirectX provides breathtaking graphics, sound, music and three-dimensional animation that bring games to life. Direct X is also a link that allows software engineers to develop a game that is high speed and multimedia driven to your computer. Direct X was introduced in 1995 and its popularity is soaring as the development of multimedia applications has reached new heights. Today, Direct X has evolved into an Application Programming Interface (API) that apply to Microsoft operating systems Windows. This means software developers to access hardware features without having to write code material. 
Some of the features of windows media playerb 9 Series with smart jukebox gives users more control over their music. With easy cd transfer to PC, CD and compatibility is available on portable players. Users can also discover more with services having premium entertainment. Windows Media Player 9 seriers works well with Windows XP using the built-in digital media features, and offers a state-of-the-art experience.When Windows Millennium Edition 2000 came from the stores specifically designed for home users. It was the first version of a Microsoft product video editing. Movie Maker is used to capture and organize and edit video clips, then export them to PC or play web. Movie Maker 2, released in 2003, the film adds a new transition, jazzy titles and neat special effects. Based on Microsoft Direct Show and Windows Media technologies, Movie Maker only originally included with Windows Millennium Edition. Now Movie Maker 2 is available for Windows XP Home Edition and Windows XP Professional. 
With the release of Windows XP, 2001, came the Windows Messenger, bringing instant messages to users via the Internet. Users communicate with text messages in real time Windows Messenger. Real-time messages with video conferencing is available for a long time ago now. The first communication tool provided by Windows Messenger is used comprehensive, easy to use text chat, voice and video, and data collaboration. 
Linux is developed and thus is free for distribution in encrypted form. Linux is developed and available via the Internet. Many of the engineers involved in the production are from over seas and never meet each other. This operating system is the source code level and on a large scale has led the way to becoming a stable and featureful system. 
The Eric Raymond has written a popular essay on the development of Linux called The Cathedral. and the bazaar. Describes how to use a Linux kernal approach bazaar has released the code quickly and often, and this requires input provided by improving the system. This approach Bazaar has been reported that the Metropolis approach used by other systems such as core GNU Emacs. The approach is characterized cathedral for the pursuit of the most beautiful code has been released, but unfortunately it is released much less frequently. A poor opportunities for people outside the group can not contribute to the process. 
Some high-lights and the success of projects Bazaar does not include the opening of the code for everyone to observe, in the planning of Bazaar. By the same logic approach Cathedral is widely regarded by everyone and is appropriate. When debugging the code is executed, it is necessary to open the bazaar to have everyone find several errors on the code. If they can fix the code a lot of effort and help developers. 
Advantages and disadvantages of the two operating systems 
The author of this web Linux OS page Chris Browne, describes how the Linux efforts and distributed some of the advantages and disadvantages of Linux OS. The Linux OS comes with some experimental versions like 2.5. x series where the version numbers go up steadily each week. The stable version only changes when errors are detected in the system and errors must be determined by the test series, and this incident does not change very often. Linux users know that this is happening, and work to resolve the errors.There is no guarantee that all users will immediately fix their problems with their systems, if not affected (or did not notice that influenced) by the problems there are fixes available quickly, sometimes distributed across the Internet after several hours of diagnosis. For Linux fixes are available more quickly than commercial vendors such as Microsoft, HP, IBM, and usually such a diagnosis is before you even know that there is a problem. This recognition contrasts with other companies conduct, Bill Gates claims the press release of Microsoft code has no bugs. This seems to mean that there are bugs that Microsoft is keen to correct. 
Microsoft has concluded that the majority of errors identified in the present systems, because users do not use their software properly. The remaining problems for Microsoft are few in number and are caused by errors of fact. There is remaining work to get a stable system Linux, configured with Linux kernels that have and have configured the software over the workload of the system should run for hundreds of days without rebooting the computer. Some of the general public as well as IT professionals, such as engineers and technicians complain that Linux is always changing. Chris says that "the effort and interest kernal Linux will stop when people want to stop building and strengthening the Linux kernal." As long as new technology and devices such as video cards manufactured and people interested for Linux invent new enhancements for Linux, work on the Linux OS will progress. 
The disadvantage of Linux OS is that it may end because there is a better platform for kernal hacking, Linux, or because the future will be displaced so as to become unwieldy. This has not happened yet, but many researchers say the future of Linux, with various plans to achieve service to the consumer or enterprise, Linux is removed from the base kernal and user space, which creates less room for data and information . The announcement of an attempt Debian Hurd propose an alternative solution to the kernal hacking. The kernal Hurd, which runs and sent as a set of processes on top of a microkernal as MACH, may provide a system for people who are dissatisfied with changes to the linux kernal. Mach has a "message passing" abstraction that allows the operating system created as a data set that will work in conjunction with one another. 
Competitive, cooperative efforts 
To start this section will tell you to start the PC and roots with IBM. Vertically integrated proprietary de facto standards architecture was the norm for the first three decades of the postwar computer industry. Each computer manufacturer, now all the technology, if not inside, and that the technology is sold as part of an integrated computer. This time the systems were steadily rising since 1964 the introduction of the IBM System 360 to release the 1981 personal computer from IBM. This was denied by two different approaches. One was the fragmentation of proprietary standards in the field of computers among the various suppliers, which led Microsoft and Intel to seek industry wide prevalence of proprietary component of the overall system architecture, making what Moschella (1997) in the era of the PC "(1964 - 1981). The second was a movement by customers and second tier manufacturers to cvonstruct industrywide «open" system in which the pattern belonged to a single company. 
The adoption of the Linux system in late 1990 was a response to these earlier approaches. Linux was the most commercially acceptable example of a new wave of "open source" software, software source code is distributed free to use and modify. The advantages of Linux as opposed to proprietary standards PC, especially by the standards of the software tested by Microsoft. Specifications Product compatibility is generally considered using a simple typology unidemensional, bifurcated between "compatible" and "inconsistent." Even more to illuminate the differences between proprietary and open standards strategies, (1987) Gabel is multidimensional ranking status, with each dimension assuming one of the many (discrete) levels: 
"Multivintage" compatibility between successive generations of the product: 
"Order Products" compatibility, providing interoperability between the breadth of the company 
range of products such as Microsoft with their families Windows CE, 95/98/ME, NT/2000 and product. 
"Multivendors" compatibility, ie compatibility between products of competing manufacturers. 
The first successful operating system was a multi-vendor Unix, developed by a team of computer science at Bell Telephone Laboratories (BTL), for the opening of New Jersey in 1969. As with the previous Multics research project between MIT, BTL and mainframe computer maker General Electric, Unix was a multi time-sharing operating system designed as a research project by the developers for their personal use. Other features key to the success of Unix path dependencies reflected by the developers and early users (Salus 1994): 
AT & T was forbidden from 1956 consent decree from being in the business of computers, why not sell the operating system business. Following the publication of research papers, Bell Labs had been flooded with requests from the departments of computer science university, who received licenses and source code, but the lack of support. With the budget constraints that limit the cam researchers BTL to December contrast medium to large computer mainframe, Unix was simpler and more efficient than its predecessor Multics, based on a simplified programming language C and not the most widely used PL / I. Although originally developed in December, Unix converted to run on other models by users who have found time programmer cheaper than buying a supported model, so laying the foundation to become a hardware-independent operating system. 
Perhaps one of the most significant development was the licensing of UNIX by the UC Berkeley Computer Science Department in 1973. The Berkeley group issued their own versions of 1977 to 1994, with much of its funding provided by the Defense Advanced Research Projects Agency (DARPA). The result of the development contained Berkeley (Garud and Kumaraswamy 1993? Salus 1994): 
The first version of Unix to support the protocol TCP / IP, after the standard Internet protocols; 
Academic version of BSD Unix as the preferred OS in several departments of computer science around the world; 
Commercial distribution of BSD Unix derived through Sun Microsystems, cofounded by former programmer BSD Bill Joy? 
It evolved versions of Unix, the fragmentation of Unix programmers and take on rival "BSD" and "AT & T" camps. 
The AT & T Unix provided a standard different manufacturers, when combined with developments in BSD, helped spur the adoption of networked computers. Helped by the Sun, whose motto is "the network is the computer,« Unix quickly gained acceptance during the 1980's as the preferred OS for networked engineering workstations (Garud and Kumaraswamy 1993). At the same time, there was a real model from different manufacturers, such as producers minicomputer with a small amount of customers, the inability of R & D and immature OS license Unix from AT & T. The main exceptions to the head of Unix were among the first leaders in power work (Apollo) and middle (December), which used its own OS as a source of competitive advantage, and was the last to switch to Unix in their respective categories. 
Some supporters of the two producers have created a range of professional associations to promote Unix and related operating systems. Thus fueled the adoption and standardization of Unix, which hoped to increase the amount of applications software to compete with the sponsorship, proprietary architectures (Gabel 1987? Grindley 1995). These two teams are promoted under the title "open systems"; Authors of a series of books on these systems are summarized objectives as follows:Open systems allow users to move applications between systems easily; Purchasing decisions can be based on the ratio of cost-effectiveness and vendor support, rather than on systems running a suite of application users (Salus 1994: v). 
Despite these objectives, the Unix community spent 1980 and early 1990, fragmented into AT & T and Berkeley warring factions, each of which sought control of the OS API to maximize the software available for versions them. Each faction had its own supporters. To avoid paying the old mainframe before switching costs, the U.S. Defense Department procurement decisions began to favor a proprietary Unix systems. As AT & T formalized System V Interface Definition and encouraged hardware makers to adopt System V, became the model from different manufacturers are required by the commission of the Ministry of Defence 
BSD group was only developed in middle December, Unix variant was no different manufacturers and less appealing and attractive to DoD contracts. Numerous innovations in the BSD group on usability, software development tools and networking made it more attractive for Computer Science for their research and teaching, making it the minicomputer OS they prefer the services of computer science in the U.S. , Europe and Japan (Salus 1994). The divergent innovation meant that the two major Unix variants differed in terms of internal structure, the user commands and application programming interfaces (API). It was the difference last hit more computer buyers, such as custom software developed for one type of Unix could not immediately be reviewed by the other, adding the transition costs of the two systems. Also, both the modem based on its DARPA networking facilitated the distribution of user-donated code libraries, which was free, but often required for site-specific custom programming, if the Unix API in user space differed from those faced by the the original donor. 
Microsoft Windows continues to invest in a product family based processor Itanium, and the Itanium Solutions Alliance will promote investment, helping to develop the ecosystem of applications and solutions available for the Windows platform and SQL Server 2005, "said by Bob Kelly, general manager, Windows infrastructure, Microsoft Corp "We look forward to working with members of the Itanium Solutions Alliance to help IT managers move from RISC servers based on Unix to Itanium-based systems running on the platform Windows.

Does the Seagate FreeAgent Pro External Hard Drive Support a 64-Bit Operating System?

FreeAgent Pro drives work with 64-bit operating systems.The Seagate FreeAgent Pro range of external hard disk drives all function on 64-bit operating systems. However, the Microsoft Windows software utilities supplied with the drive are not 64-bit compatible. The Seagate FreeAgent Pro range includes external hard disk drives with capacities of up to 1 terabyte (TB). The drives are usually used for system backup or to store libraries of data or media files. A 64-bit operating system, such as Windows 7 64-bit, is able to recognize the drive when you connect it to your PC, and allows you to move files between the device and the hard drive on your <a href="">computer</A>. The bundled software will only work with 32-bit versions of Windows. If you plan to use a FreeAgent Pro hard drive with your 64-bit system and have no intention of utilizing the bundled software, you should experience no functionality problems. If you wish to use the software utilities, it would be better to buy a more recent drive from the FreeAgent range, which includes 64-bit compatible software.

Selecting a Secure Wireless Device and Operating System

Security considerations remain the single biggest limitation to the more aggressive roll-out of mobile devices in many organisations. It is crucial that companies consider device selection based on its inherent platform security capabilities, in particular around the security embedded within the device Operating System (OS).Deployment of mobile or wireless access within organisations is growing at an accelerating rate, this has been achieved through a number of factors including attractive pricing, faster, less costly and a more reliable wireless network both in the UK and globally, which are being continually deployed over wider areas. Add to this the now abundant range of business functions and applications and it's easy to understand the take-up.However for the more alert organisation there is uncertainty or an inherent fear of data loss and leakage, specifically those with regulatory compliance or enhanced security requirements (e.g., financial, insurance, investment, legal, and public sector). Such organisations cannot afford to deploy anything that could compromise their data or records security or prevent them from meeting such regulatory compliance. Mobile devices are easily misplaced or stolen, this represents a risk that while real, can be managed with proper planning and foresight. The first and most important decision a company can make in ensuring a safer mobile working environment for both end user and business is to select a device that exhibits high levels of inherent security. As in life, not all devices were created equal, it is imperative that companies evaluate devices based on its intrinsic platform security capability, particularly around the security embedded within the device Operating System (OS).There are a number of important components that make an OS secure and safe for business use, this article will explore the key components necessary in selecting, deploying and managing a mobile operating (OS) so that enterprise use of the device will not compromise the integrity of the company's security efforts and put it at risk for costly legal or governmental action. The article will compare these attributes on three operating systems, BlackBerry OS from Research in Motion (RIM), the iPhone OS from Apple and the Windows Mobile OS from Microsoft.Authentication; users should not be able to work on any device without adequate levels of authentication to prove that he/she is the owner of the device. Passwords and two factor authentication are being deployed currently, with biometrics being added in the near future. Any device that can't force user authentication through enforced IT policies should not be considered a security ready business class device.BlackBerry OS allows the company IT department, through the use of the BlackBerry Enterprise Server (BES), to set a robust policy making it mandatory that the user logs into the device via a strong password, furthermore BlackBerry allows token-based two factor authentication and secure peripheral devices to be added (e.g., card reader). The user does not have the ability to change or bypass this policy once set by the IT department. The policy is also extremely granular (e.g. by user, group, entire company) this ensures that different users can have unique policies specifically addressing their need or indeed job role. The iPhone provides a log-in password that allows locking of the device and the characteristics of the password can be set by the IT department by deploying a policy to the device. However it is possible to override this IT policy if the user chooses - which kind of defeats the object. Certain policies can be enforced if using ActiveSync for Exchange connectivity.All iPhones require connection to a PC running iTunes for initial activation on the network, the iPhone when connected with iTunes will create a complete backup of the device on that PC. Therefore the data on the device could be accessible from the PC, this posses a potential security threat. It's also worth noting that many of the enforced policies require that the company is running Exchange 2003 or 2007 with ActiveSync. Windows Mobile via ActiveSync and Exchange can also enforce password locking in a strong manner, and once set users are not able to bypass. However full policy setting requires the use of Microsoft System Centre Mobile Device Manager (MSCMDM), a product that requires purchase and is not integrated into other Microsoft products.Reliability; any enterprise class mobile OS should display the reliability end users expect from a robust business device, this means that the device should never simply decide not to work, or require unexpected re-boots. In a business spec device any irregularity with the OS (e.g. crashes, freezing) may cause more than just inconvenience, they will cause lost work, lower productivity, raised support costs not to mention end user frustration something that is often overlooked. Any device or OS being considered within an organisation needs to be examined for its ability to withstand the organisations working model.BlackBerry consistently delivers a high level of stability and an almost complete lack of freezing or crashing, as a result few users report problems with lost work and devices rarely require a re-boot, the upshot being a very limited support cost. Similarly iPhone's OS has had very few unexpected interruptions and works well for most users. Windows Mobile, much like its PC OS counterpart is well known for OS crashing, whilst newer versions are improving this tag users still report annoying application crashing and frequent loss of data, with most crashes requiring a device re-boot.Tamper resistance; it is critical to know immediately if a devices OS has been hacked or whether attempts have been made to alter the base level OS. Although malware isn't prevalent on smartphones, it will be and many hackers view this as an attractive and new sector to attack. The more resistant the OS, the less likely malware can infect the platform, this reduces risk to the device and the spread of infection within the business. Operating Systems that allow applications deeply into the core of the OS represent a higher risk than ones that run applications at a higher level.BlackBerry is extremely difficult to hack, the OS must boot in a known state with a known signature before the device will initiate, this means the OS itself is checked before each boot. All third party applications run in a Java virtual machine meaning that hacking into the base OS of the device is extremely difficult if not impossible. The iPhone is difficult to access on the device, however there have been a number of successful attacks against the Safari browser compromising the device. Applications run in administrator mode meaning that should the device be compromised by an infection, it has almost unlimited access to the whole OS.There have been recent examples of malware emerging for Macs and as the iPhone OS has a similar core code as the AppleMac OS X it is expected attacks on the iPhone OS will increase. It is fair to say that this OS has some maturing to do to be classed as robust and secure, organisations should also be cautious as the popularity of the device will undoubtedly increase its target! Windows Mobile has always displayed hacking friendliness in the past as many of its core functions are exposed, there are currently a number of third party applications for anti-virus and malware protection. With increased malware attacks in the PC world it is likely the volume and frequency of attacks to Windows Mobile will also increase.Security vs. usability; pretty much all OS can be totally locked down preventing any interaction with the OS, however whilst it is key to maintain security levels it must be done in an environment that enables maximum usability. Companies considering highly secure devices should test-drive the security in conjunction with the usability of the system and whether the end users find the OS easy to use, navigate and customise for personal preference. It's fair to say that one size does not fit all and the level of security must be balanced against user needs, however the final choice should always be weighted towards security than usability should a trade-off be required.BlackBerry provides an extensive number of policies all from the control of the BES and these can be deployed over the air (OTA). The BES is the central control point for all features and policies and no user can override them ensuring full IT control. This mode of security makes it transparent to the end user, as it is fully integrated within the OS and requires no knowledge or intervention on the part of the user and as with the authentication component it is all very granular meaning different levels can be applied depending on employee and/or job function. Whilst the iPhone does have some capability for device management and policy setting, the number and type are very limited.The profiles have to be delivered to the iPhone either via users surfing to a secure webpage or installing the profile through delivery in an email message, this user intervention places a burden on the user and an obvious risk of non-compliance. Also the iPhone allows users to reconfigure any device through menu screens thus overriding IT settings, this is a very insecure way of configuring a device. Windows Mobile devices can be managed through the deployment of MSCMDM, providing many management functions available within Exchange, for example, device encryption, device wipe etc. As MSCMDM isn't integrated into standard system management tools and requires possibly several standalone servers, there is an additional cost, support and impact to the solution.Meeting security validations; many industries require that a device be validated and approved by governmental agencies to ensure they meet security testing and specification before deployment. Whilst many devices 'claim' to be compatible with certain security standards, it is absolutely crucial that they have been approved and validated and not just be simply compatible, this applies not just to current standards but to the constantly evolving requirements placed on security from industry and government agencies. The key starting point is the OS, no device can meet these strict security guidelines unless the OS is capable of achieving the stringent approval process.The clear leader in this section is BlackBerry, having applied for and attained a wealth of certificates and validations for its devices and operating system, including FIPS 140-2, NATO restricted classification, UK CAPS restricted classification, and common criteria EAL 2+ certification. In addition BlackBerry provides the functionality to select the most common encryption algorithms (e.g. AES, 3DES) to protect data on the device, and provides complete remote device wipe.Apple have not declared any intention to seek regulatory certification or validation of the iPhone, furthermore key features such as remote device wipe require ActiveSync and Exchange 2003/2007 deployment at the company, Apple also recommends having the device plugged into a mains charger when wiping... No on board data encryption is available for the iPhone, therefore it is fair to say that with these handicaps the likeliness of the iPhone achieving any of the security validation requirements in the near future is extremely slim. Windows Mobile 6 devices provide encryption for common standards such as 3DES and AES and also provide a remote device wipe through ActiveSync when used with MSCMDM and Exchange. Whilst Microsoft is pursuing validation for its devices for FIPS it is yet to be broadly recognised by other validation bodies.In summary it is fair to say that wireless mobile devices pose a security challenge for organisations with a highly mobile workforce, but this risk can be carefully managed by selecting an enterprise class platform with an OS that includes the key features to secure the device and its data. Based on the comparison detailed above I summarise that the most secure platform for business use is the BlackBerry platform. Windows Mobile continues to improve and has implemented some significant enhancements to its recent version, but still not of the calibre of BlackBerry, it may however be a viable option for companies able or willing to work with third party add-ons to avoid its shortcomings. The iPhone has serious difficulties when it comes to business class security, and at this stage in its evolution I would not recommend the iPhone for any organisation concerned about protecting the security and integrity of its mobile data and especially for any organisation that must adhere to strict industry regulation.Companies should remain alert and ensure they balance user wants and needs for a device with the necessary requirements to protect company confidential information through the deployment of platforms designed for security and their corresponding technologies behind the firewall, failure to do so may produce serious problems resulting in fines, regulatory non-compliance, legal challenges and ultimately a loss in revenue.
