Abstract: Network security is an important aspect in every field like government offices, Educational institute and any business organization. Network security is a challenging problem due to the complexity of underlying hardware, software, and network interdependencies as well as human and social factors. It involves decision making in multiple levels and multiple time scales, given the limited resources available to both malicious attackers and administrators defending networked systems. The resources vary from bandwidth, computing, and energy at the machine level to manpower and scheduling at the organizational level.Data security is the extreme critical factor in ensuring the transmission of information via the network. Threats to data privacy are powerful tools in the hands of hackers that could use the vulnerabilities of a network to corrupt, destroy and steal the sensitive information. There are more network security measure to protect the data from attackers like antivirus software, firewalls, cryptography etc. In this paper we study about various types of attacks on network security and how to handle or prevent this attack.
