ABSTRACT

This paper takes a keen look in network security and network security goals, why computers are insecure and type Of attack, how to improve network security . Securing your network and practical's what is Quota.

 Network security comprises the measures a company takes to protect its computer system, and it is a prime concern for every company that uses computers. Compromised network security means a hacker or competitor may gain access to critical or sensitive data, possibly resulting in data loss, or even complete destruction of the system .

Network Security Goals 

   Confidentiality: only sender, intended receiver should “understand” message contents sender encrypts message receiver decrypts message Privacy: hide `who is doing what with whom

Authentication: sender, receiver want to conform identity of each other

Integrity: sender, receiver want to ensure messages are not altered (in transit, or afterwards) without detection

 Access and Availability: services must be accessible and available to users Network Security

Why Computers are Insecure ?

 Most PCs use insecure Ross

Most designed for `home` - security not a goal Others support separation between users

Few/none restrict capabilities of applications

Malicious / vulnerable / buggy app can harm all!!

 PCs run buggy, vulnerable, even malicious code Many sources (libraries, shareware, …)

 Limited awareness & tools.

 Limited product liability and consequent damages Most computers don’t fix known vulnerabilities
