Network Security

Network Security refers to the proper safeguarding of everything associated with a network including data, media, and equipment. Network Security Systems are security procedures and controls that protect a network from:

(a) unauthorized access, modification, and information disclosure

(b) physical impairment or destruction.

They often includes features like threat assessment, cryptographic products and fire walls to anticipate and foil hackers and other would be intruders. In this way Network Security Systems make certain that your company's network resources are used in accordance with prescribed policy and only by people who are authorized to use them. Network Security Solutions provide businesses with the tools necessary to keep networks running safely and smoothly without compromise of integrity and without needless and costly downtime.

 Computer security is the effort to create a secure computing platform, designed so that agents (users or programs) can only perform actions that have been allowed. This involves specifying and implementing a security policy. The actions in question can be reduced to operations of access, modification and deletion. Computer security can be seen as a subfield of security engineering, which looks at broader security issues in addition to computer security.

It is important to understand that in a secure system, the legitimate users of that system are still able to do what they should be able to do. It has been said pejoratively that the only truly secure computer is one locked in a vault without any means of power or communication; however, this would not be regarded as a useful secure system because of the above requirement.

It is also important to distinguish the techniques employed to increase a system's security from the issue of that system's security status. In particular, systems which contain fundamental flaws in their security designs cannot be made secure without compromising their utility. Consequently, most computer systems cannot be made secure even after the application of extensive "computer security" measures.
