Network security is a challenging issue due to the complexity of underlying hardware, software, and network not independence between things as well as human and social factors. It involves decision making in multiple levels and multiple time scales and in multiple scenarios, given the limited resources available are malicious attackers and administrators defending network system. The resources be different from bandwidth, computing, and energy at the device level to manpower and schedule at the organizational level. Nowadays Data security is the extreme critical factor in ensuring the transmission of information via the network around the world. Threats to data privacy are most powerful tools in the hands of hackers that could use the vulnerabilities of a network to corrupt ,hack, demolish and steal the sensitive information. There are more network security measure to keep safe the data from attackers for example antivirus software, firewalls, cryptography etc. In this paper we study various types of attacks on network security and how to handle or prevent this attack, also studied that firewall work based on the port hoping so it break the security to overcome on this we see the application awareness Firewall.
