Firewalls - An Introduction

A firewall is a piece of software (There are also hardware firewalls but we are going to discuss software only) that blocks or allows incoming or outgoing connections from your computer. I would probably recommend that every computer user should have one as they can protect your computer from hackers, viruses, trojans etc. They are also useful when trying to prevent someone from connecting to an internal service in an organisation, for example an Intranet. There are a number of techniques a firewall can use to defend you computer:- Packet filter - Application gateway - Proxy serverPacket FilterThis type of firewall inspects every packet that tries to enter your computer. It will look at each individual packet and analyse it based on a set of rules. as to whether it is safe or dangerous. These rules can be based on source IP address, destination IP address, which port it is coming through, the type of service (FTP, Internet etc.) plus many other factors can be taken into account.Application gatewayAn application gateway is when a firewall will inspect any program trying to access/connect with your computer, these are especially effective against stopping any viruses or trojans as they recognize the program and prevent it entering your computer and causing any damage.Proxy serverA proxy is kind of like a veil, it will block anyone from seeing your true IP address, making it harder for anyone to hack/connect with your computer. There are of course ways around this but it adds an extra challenge for the attacker.This is just a basic introduction to firewalls and the technology they use to protect your computer.

Introduction to Cloud Computing

1. Introduction to Cloud ComputingCloud computing refers to both the applications delivered as services over the Internet and the hardware and systems software in the data centers that provide those services. The data center hardware and software is what we will call a Cloud. Cloud computing is relatively new concept and it has become popular recently. Cloud leverages virtualization technology and in the essence of Cloud computing there is a logical separation between different nodes, each node appears as a different physical machine to the user. Unlike grid computing, it makes several distributed computers connected together to form a big logical computer which can handle large amount of data and computation. In case of Cloud computing the virtualization technology makes it possible to have each node appear as separate physical machine allowing user to load custom software and operating system on each node and configure custom rules for each node.The idea of Cloud computing is evolved from parallel processing, distributed computing and grid computing. There is a bit similarity between them but they work differently. Although Cloud computing is an emerging field of computer science, the idea has been around for a few years. It's called Cloud computing because the data and applications exist on a "cloud" of Web servers. To simplify the concept, Cloud computing can be defined as simply the sharing and use of applications and resources of a network environment to get work done without concern about ownership and management of the network's resources and applications. According to Scale, with Cloud computing, computer resources for getting work done and their data are no longer stored on one's personal computer, but are hosted elsewhere to be made accessible in any location and at any time.2. Related Technology Comparison2.1. Grid computing A form of distributed computing and parallel computing, whereby a 'super and virtual computer' is composed of a cluster of networked, loosely coupled computers acting in concert to perform very large tasks2.2. Utility computing The packaging of computing resources, such as computation and storage, as a metered service similar to a traditional public utility, such as electricity.2.3. Autonomic computingComputer systems capable of self management.3. General mechanismCloud computing using information technology as a services over the network. The concept generally encompasses of Infrastructure as a service (IaaS), Platform as a service (PaaS) Hardware as a Service (HaaS) and Software as a service (SaaS). It can be the ability to rent a server or servers and run a geophysical modeling application available anywhere. It can be the ability to (S Rupley, 2009) rent a virtual server, load software on it, turn it on and off at will, or clone it to meet a sudden workload demand. It can be storing and securing large amounts of data that is accessible only by authorized applications and users. It can be supported by a cloud provider that sets up a platform with the ability to scale automatically in response to changing workloads. It can be using a storage cloud to hold application, business, and personal data. And it can be the ability to use a handful of Web services to integrate photos, maps, and GPS information to create a front page in customer Web browsers.In a cloud computing system, there is a significant workload shift. Local computers no longer have to run applications. The network of computers that make up the cloud handles them instead. In this situation the demand of hardware and software on the user's side is decreased. Let the cloud take care of it. The only thing that local computers should aware is the interface software that will run the application. Today's, a Web Browser such as Mozilla Firefox and Internet Explorer 8 is widely use as an interface software in cloud computing system.The truth is, internet users already used some form of cloud computing. If they have an email account with a Webbased email service like Hotmail, Yahoo! Mail or Gmail, then they had some experience with cloud computing. Instead of running an email program on a local computer, user will log in to a Web email account remotely. The software and storage for the account does not exist in the local computer it is on the service's computer cloud.4. Key characteristic of Cloud ComputingCurrently, there is no standard definition or specification for Cloud Computing. It may take some time to define the key characteristics of Cloud Computing based on practices in the field.Based on practices in the areas of service provisioning and solution design, the following two key enabling technologies could play a vital role in this revolutionary phase of cloud computing:4.1. Virtualization technologyVirtualization technology works to handle on how the image of the operating system, middleware, and application procreated and allocated to a physical machine or part of the server stack away. The virtualization technology can also help reuse licenses of operating systems, middleware, or software applications, once a subscriber releases their service from the Cloud Computing platform.4.2. Service Oriented Architecture (SOA).A service oriented architecture is essentially a collection of services. These services communicate with each other. The communication can involve either simple data passing or it could involve two or more services coordinating some activity. Some means of connecting services to each other is needed. The evolution of a system or software architecture is now moving towards services oriented, unlike several decades ago most of the application is stand alone and purposely for single use. Recently, the gigantic growth of the internet user and internet technology availability the use of software now can be rented. Giant company such as Google, Microsoft, Sun or even Amazon have this capability provide software services instead of selling the software directly to user. The SOA is software or system architecture that addressing componentization, reusability, extensibility, and flexibility. These entire characteristic is a fundamentals need for company that are looking for reducing cost and opt to rent instead of purchase.	 	 		 			 				 					 						<a href="http://www.zuraidin.com/2010/04/cloud-computing.html" target="_new">Cloud Computing full document</a>

An Introduction to Internet Security Software

Internet security involves the protection of a computer's Internet account and files from any form of attack or intrusion of an unauthorized user. Unauthorized access of a computer may occur once the computer connects to a network and begins communicating with other computers or accessing a malware-infected web site through the Internet. To avoid this, it is recommended to set up a password and install an Internet security software. The following are some major Internet threats that can badly jeopardize a computer: Malware Worms Bots Spyware Trojans Viruses The Internet threats mentioned above can be overlapped and combined, which can cause serious damage to your computer's system and personal files. These threats are the reason why they are made to detect and eliminate viruses and other forms of malicious attacks that can easily enter your computer. Internet security programs can be purchased or downloaded for free via the Internet. However, one should be careful in selecting the Internet security software that they will use since some programs are not as effective as the others when it comes to detecting and removing viruses or malware. One should also be cautious when downloading such Internet security software since there are some existing websites that contain web links that would instruct you to install a security program for your computer, when in reality it would actually install malware or even viruses on your computer. Most Internet security software have antivirus, firewall, antispyware, as well as parental controls already integrated into one program to help you protect the following:Personal information - Internet security programs contain antispyware, firewall, and anti-phishing protection to secure your sensitive data from creative hackers who are constantly using latest developments in technology to gain access to personal information.Computer system - Internet security programs can shield your computer from being attacked by different kinds of viruses in forms of email attachments and other files, which may render your computer useless.Family restriction - Parental controls are also included that allows you to filter and to restrict access of unacceptable sites or web contents that can also harm your computer. This feature can also keep your children from any possible online predators.When looking for a reliable software, the following are some important criteria that a computer user must remember before downloading a particular program:Ease of installation/setupAn Internet security software must be easy to install and to set up. It should have a clear and step by step instructions in order to avoid application errors or interfere with other programs in the computer.Ease of UseAn Internet security software must be designed so that every user can be able to use the software regardless of their computer literacy. This also involves the program's interface as well as the terminologies used that will help the user to easily manage the software.Other security featuresA reliable Internet security software must have additional Internet security programs bundled such as email and IM scanning, anti-phishing, and parental controls.AntispywareAn Internet security software must have an antispyware function that will protect your computer against adware, keyloggers, trojans, and many more.FirewallAn Internet security software must have a firewall protection that will shield your computer against outside attackers or malicious Internet traffic. There are two types of firewalls namely: Hardware - These are typically called network firewalls, which refers to external devices that are usually placed between your computer or network and your cable or DSL modem. Some Internet Service Providers (ISP) or vendors offer networking devices, such as a router, that already has a firewall installed. Hardware-based firewalls have the advantage of being separate devices, which are running on their own operating systems so they provide additional line of defense against Internet attacks. Software - These are firewalls that are built-in within the computer's operating system. If your computer's operating system has a firewall feature included, you may consider enabling it to provide an additional layer of protection even if you already have an external firewall. Antivirus A security software must have the ability to continuously scan your computer for any harmful viruses. It is also important that the antivirus you are using are regularly updated to detect new viruses since these threats are constantly evolving.Help and SupportManufacturers should be able to provide support to its customers through FAQs, user manual, or tutorials on how to properly use and maintain the Internet security software. It is also important that customers will obtain support through phone, chat, or email at all times.
