Networking security
Network administration measures to ensure data integrity include: maintaining current authorization levels for all users, documenting system administration procedures, parameters, and maintenance activities, and creating disaster recovery plans for breeches, losses and virus attacks.

About Network Security
Data and network security must be maintained so that information can only be accessed or modified by those authorized to do so. In any well run business, it is wise to construct a comprehensive security policy. This consists of plans and procedures which are in a document that states how a company will protect the company's physical and information technology assets. A company's security policy may include an acceptable use policy, a description of how the company plans to educate its employees about protecting the company's assets, an explanation of how security measurements will be carried out and enforced, and a procedure for evaluating the effectiveness of the policy.

One Solution: Firewalls
A firewall is a set of related programs, located at a network gateway server, that protects the resources of a private network from users from other networks. Basically, a firewall, working closely with a router program, examines each network packet to determine whether to forward it toward its destination. A firewall also includes or works with a proxy server that makes network requests on behalf of workstation users. A firewall is often installed in a specially designated computer separate from the rest of the network so that no incoming request can get directly at private network resources.

Computer Viruses
A virus is a piece of programming code usually disguised as something else that causes some unexpected and usually undesirable event. A virus is often designed so that it is automatically spread to other computer users. Viruses can be transmitted as attachments to an e-mail note, as downloads, or be present on a diskette or CD. The source of the e-mail note, downloaded file, or diskette you've received is often unaware of the virus. Some viruses wreak their effect as soon as their code is executed; other viruses lie dormant until circumstances cause their code to be executed by the computer over the Internet.

Some viruses are playful in intent and effect ("Happy Birthday!") and some can be quite harmful, erasing data or causing your computer's hard disk to require reformatting.

Generally, there are three main classes of viruses:
File infectors. Some file infector viruses attach themselves to program files, usually selected .COM or .EXE files. When the program is loaded, the virus is loaded as well. Other file infector viruses arrive as wholly-contained programs or scripts sent as an attachment to an e-mail note.
System or boot-record infectors. These viruses infect executable code found in certain system areas on a disk. They attach to the Master Boot Record on hard disks.
Macro viruses. These are among the most common viruses, and they tend to do the least damage. Macro viruses infect your Microsoft Word application and typically insert unwanted words or phrases.
The best protection against a virus is to know the origin of each program or file you load into your computer or open from your e-mail program. Since this is difficult, you can buy anti-virus software that can screen e-mail attachments and also check all of your files periodically and remove any viruses that are found.
