Introduction
Computer forensics is the practice of collecting, analysing and reporting on digital information in a way that is legally admissible. It can be used in the detection and prevention of crime and in any dispute where evidence is stored digitally. Computer forensics has comparable examination stages to other forensic disciplines and faces similar issues.

About this guide
This guide discusses computer forensics from a neutral perspective. It is not linked to particular legislation or intended to promote a particular company or product and is not written in bias of either law enforcement or commercial computer forensics. It is aimed at a non-technical audience and provides a high-level view of computer forensics. This guide uses the term “computer”, but the concepts apply to any device capable of storing digital information. Where methodologies have been mentioned they are provided as examples only and do not constitute recommendations or advice.

Uses of computer forensics
There are few areas of crime or dispute where computer forensics cannot be applied. Law enforcement agencies have been among the earliest and heaviest users of computer forensics and consequently have often been at the forefront of developments in the field. Computers may constitute a ‘scene of a crime’, for example with hacking [ 1] or denial of service attacks [2] or they may hold evidence in the form of emails, internet history, documents or other files relevant to crimes such as murder, kidnap, fraud and drug trafficking. It is not just the content of emails, documents and other files which may be of interest to investigators but also the ‘meta-data’ [3] associated with those files. A computer forensic examination may reveal when a document first appeared on a computer, when it was last edited, when it was last saved or printed and which user carried out these actions.

Open Source (Free) development is a methodology of creating software products from the design, development to its distribution. Developers often distributed such free software under the GPL (General Public License). This methodology provides a source code access to anybody and everybody aspiring to develop the software further for the good.

The evolution of Open source development

During the period of 50′s and 60′s, software were distributed free of cost to enhance the functionality of the hardware or to promote the hardware. People involved in the computer business dealt with hardware and freely distributed codes to encourage hardware sales. Also, buyers often had to change the code to make it work according to their business. They also had to fix bugs or add new features supporting hardware issues.

During early 1970′s, operating system and compilers began to grow rapidly. This development phase led to the surge in software demand, which had software companies to begin charging for the software licenses. Software started selling with several legal restrictions including copyright, trademark and leasing contracts.

The Open Source trend evolved during 1984 and 1985 when Stallman started the GNU project with an ultimate goal of getting the operating system developed and edited by genius developers without the expensive licensing issue and source code restrictions. This promoted Open Source development not only for operating system, but also for other areas of computing. Later, GNU General Public License became a legal tool ensuring that software under the GNU will remain free.

Open source framework programming advanced and today major companies accept its integration. This system developed some of the most famous and robust software namely Mozilla Corporation products, Firefox; Linux and UNIX operating systems; LAMP software stack and so on.

The Concept

If you want to remotely have access to your central organizational network, you may want to consider using a virtual private network (VPN). Although the name sounds very complicated, it is actually quite easy to use. This private network largely uses public telecommunication such as the internet to provide access to a central organizational network. This simply means that a computer can connect to another computer on the same network. With this private network you may share data and have access to network resources, printers, databases, websites, etc.

The benefit of a VPN is that there are low costs involved because it does not need physical leased lines to connect users remotely to an Intranet. The world has slowly evolved into a modernised wireless technological era. Businesses are at the advantage point and grow in capital because of smart technology and software. Virtual Private networks are faster, secure and reliable when you want to share information across computer networks. People who are traveling, sales persons, companies with many shops, offices or businesses around the world benefit hugely from this fast network.

You don’t have to worry about how safe the network is. A Virtual Private network is safe and secure, because only users with access can read the data, thus anybody else who intercepts the data will only be reading encrypted data. Privacy are ensured through security procedures and tunnelling protocols. Not only are the data encrypted, but also the originating and receiving network addresses are encrypted. Data that are send through these “tunnels” are encrypted and only the sender and receiver can read the data. Businesses wishing to grow can expand all its intranet’s resources to employees working from remote offices or their homes securely. The ultimate aim of your VPN is to grant secure access to the organization with equal resources at a better price.

Through development and deployment of plug-ins we can extend Microsoft Dynamics CRM 4.0. In this article we will discuss development, deployment and debugging of plugins. additionally we will see what tools and techniques we can use for improving your efficiency and experienced for developing plug-ins.

Applies To

• Microsoft Dynamics CRM 4.0
• Visual Studio 2005
• Visual Studio 2008

Prerequisites

We assume that you are aware of writing applications in Microsoft Visual C# or Microsoft Visual Basic.NET with the use of.NET framework. Developers who are experienced in.Net development, CRM solutions, Cloud CRM and CRM application development are aware of the framework. In order to write plug-in code you need to download and extract Microsoft Dynamics CRM 4.0 SDK and then install Visual Studio 2005 or 2008 on your PC. For deploying and executing plug-ins you need to access Microsoft Dynamics CRM on-premise or IFD server. The online one does not support upload of custom code to the server. By writing workflows you can extend the functionality of Microsoft Dynamics CRM.

How to set up the Development Environment?

To improve your experience in.Net development or CRM application development and for writing code faster with less run-time errors you need to set up an efficient development environment. You may search the Internet for tools and techniques which may help you to improve experience. It is possible to set up development environment in any computer that runs Windows XP, Windows Vista, Windows Server 2003 or Windows Server 2008. While it is also possible to develop directly on the server but it is not advisable as it affects the stability and performance of the system.
