Network security is an important task that must be seriously considered when designing a network. It defined as the policies and procedures followed by a network administrator to protect the network devices from threats and simultaneously, the unauthorized users must be prevented from accessing the network. As the numbers of attacks are increasing day by day, it is necessary to explore the information regarding new attacks and take appropriate steps to safeguard the network from malicious attacks .This could be done with the help of firewalls that secure the network from the malicious attacks.
