ABSTRACT

A tremendous amount of information and data is shared by the World Wide Web users all over the world. On an average there are 20 to 40 new vulnerabilities are discovered every month in commonly used networking and computer products. Such wide-spread vulnerabilities in software add to today’s insecure computing/networking environment. This insecure environment has given rise to the ever evolving field of intrusion detection and prevention. If a password is weak and is compromised, user authentication cannot prevent unauthorized use; firewalls are vulnerable to errors in configuration and suspect to ambiguous or undefined security policies. They are generally unable to protect against malicious activities. Hence a new approach based on the ‘Apriory approach of intrusion detection’ has been suggested to enhance the log in security to make the user more secure while using the computers.
