Internet has grown rapidly due to growth of computer technology, computer net-works and network communication technology during the recent decades. Rapid increase and tremendous growth in computer network and Internet communica-tion has increased the growth of security threats for computer networks (Kruegel et al., 2004). Everyday new vulnerabilities are exposed and attacks are occurred frequently in Internet. It makes the computer networks environment insecure and more vulnerable day by day (Ehlert et al., 2010).

Internet has grown rapidly due to growth of computer technology, computer net-works and network communication technology during the recent decades. Rapid increase and tremendous growth in computer network and Internet communica-tion has increased the growth of security threats for computer networks (Kruegel et al., 2004). Everyday new vulnerabilities are exposed and attacks are occurred frequently in Internet. It makes the computer networks environment insecure and more vulnerable day by day (Ehlert et al., 2010). These threats and vulnerabilities can interrupt and in¿uences the performance of personal, social, government and organizational operations and functions (Olusola et al., 2013). Due to this, security of computer networks has become an important issue and essential component in modern computer systems (Singh, 2004). Network security threat can take place from external intruders as well as internal users in the form of anomalous behav-ior and misuse (Anderson, 1980). Network security is a mechanism of protection from external and internal threats in order to ensure security of network com-munications (Holm, 2012). It protects network environment against unauthorized access to vital information, Denial of Service (DoS) attacks, alteration and demo-lition of data and information, and information loss. There are various protection mechanisms available like authentication and access control mechanisms, periph-eral protection mechanisms but these mechanisms are not helpful against internal intrusions. Therefore, there is an immense need for additional level of integral protection such as Network Intrusion Detection and Prevention System (NIDPS) against network intrusions. Network intrusion can arise in network träc that emerge as normal (Kruegel et al., 2004; Gollmann, 2006). NIDPS compliments the security mechanism by attempting to detect anomalous behavior and misuse and preventing from them.
