Computer Network Securities

February 18th, 2010



Computer security policies are the basic guidelines and rules for accessing a network. These lay out some basic concepts to secure your computers. Computer network security is a complicated area, and is taken up by experts with many years of on-the-job experience.

As more people turn to computers for simplifying their day-to-day activities and jobs, the need for general users to understand the concepts of network security has become important. One should know the risks involved in using the computer without the security systems, and learn how to deal with them successfully both at home and at work.

There are two popular types of network security systems: transit security and traffic regulation systems. When both of these join forces you can be assured of the delivery of important information to the right person without any network pilferage problems. The receiver should also ensure that the information received should be carefully processed using a computer which is loaded and protected with latest protection software.

The simplest form of ensuring security on the net is to keep a close watch on the type of data packets moving between the networks. If an infected packet does not reach the recipient, the host may have nothing to worry about. Traffic regulation systems serve as a protective screen between the receiver and remote sites. These tools generally guards three basic regions of the network: the routers, firewalls and hosts.

The three ‘guards’ deliver similar service at various points in the network, and it is difficult to draw a differentiating line between them. The truth is that there are no foolproof systems which offer a guaranteed secure system for data transferred in the public network. With the increasing use of the Internet, network security is fast becoming crucial for the safe use of the systems, and therefore computer network security is all set to be an important part of our regular computer usage.

How to Setup File Sharing in Windows 7

January 12th, 2010



If you have multiple computers at home and want to network them together to share files and devices then this article is for you! In this article I’ll show how to setup file sharing in a mixed environment consisting of Windows 7 and Windows XP.

The computer that will be sharing (serving) the files will be the Windows 7 computer. The computer that will be accessing the shared files on the Windows 7 PC will be a Windows xp computer. This article assumes that you either:

A: have your internal software firewalls disabled since they can often obstruct network access. Only do this if you access the internet through a router (or a wireless router).

or

B: know how to allow network access to your internal subnet. Since you’re reading this article it’s pretty safe to assume that you have no idea what I’m talking about in point B. Just go ahead and turn off your firewalls (for now at least).

On your Windows 7 computer:

1. Click the Windows globe on the bottom left (the old start button).
2. Right-click “Computer” and click properties.
3. Take note of the Workgroup name.

On your Windows XP computer:

1. Click Start.
2. Right-Click “My Computer” and click properties.
3. Click Computer Name.
4. Click Change.
5. Select Workgroup.
6. Type in the same workgroup name.
7. Click Ok twice.
8. Reboot.

Back on your Windows 7 computer lets share your documents folder to everyone in your workgroup:

1. Click Start.
2. Click Computer.
3. On the left window, under libraries, right-click documents and click share with: specific people
4. Click the drop down.
5. Select Everyone.
6. Click Add.
7. Click Read and change it to read/write
8. Click Share
9. Select My Documents
10. Click Next.
11. Sharing your documents may take awhile depending on how many have.
12. Click Done.

Back to your Windows XP PC:

You may now access documents on the Windows 7 computer by

1. Opening your “My Computer”.
2. Click “My Network Places” on the left.
3. Click “Entire Network”.
4. You should now see the name of your Windows 7 computer.
5. Double click the Windows 7 computer and you’ll see any shared files plus any shared devices.

You can follow the steps above to share any other files or folders on your Windows 7 computer.
