After overcoming some drawbacks from an improved genetic feedback algorithm based network security policy framework. A motivation was experienced for the need of a strong network security policy framework. In this paper a strong network model for security function is presented. A gene for a network packet is defined through fitness function and a method to calculate fitness function is explained. The basic attacks encountered can be categorized as buffer overflow, array index out of bound, etc. A stress is given on passive attack, active attack, its types and brute force attack. An analysis on recent attacks and security is provided. Finally, the best policy using a comparator is found.
