In today's communication system computer and information security is a major concern as these are vulnerable to potential attackers. Because to increase the potential of advanced computer communication and distributed systems leads to attack on the data flow over the network which affects integrity and availability of information greatly. Therefore, the security of web applications is a key topic in computer security. This paper presents two hybrid approaches for modeling IDS. C5.0 and HMM are combined as a hierarchical hybrid intelligent system model (C5.0-HMM).
