The most important technology for fast payload inspection is an efficient multi-pattern matching algorithm, which performs exact string matching between packets and a large set of predefined patterns. In this paper, we have proposed a novel Enhanced Hierarchical Multi-pattern Matching Algorithm (EHMA) for packet inspection. Based on the occurrence frequency of grams, a small set of the most frequent grams is discovered and used in the EHMA. EHMA is a two-tier and cluster-wise matching algorithm, which significantly reduces the amount of external memory accesses and the capacity of memory. Using a skippable scan strategy, EHMA speeds up the scanning process. Furthermore, independent of parallel and special functions, EHMA is very simple and therefore practical for both software and hardware implementations. Simulation results reveal that EHMA significantly improves the matching performance. The speed of EHMA is about 0.89-1.161 times faster than that of current matching algorithms. Even under real-life intense attack, EHMA still performs well. An intrusion detection system must reliably detect malicious activities in a network and must perform efficiently to cope with the large amount of network traffic. High attack detection accuracy can be achieved by using Conditional Random fields and high efficiency is achieved by implementing the Layered Approach. System is robust and is able to handle noisy data without compromising performance. To detect as many attacks as possible with minimum number of false alarms, i.e., the system must be accurate in detecting attacks.Keywords

APJ Abdul Kalam Technological University in Kerala was founded in the year 2014. The University has introduced many path breaking initiatives for modernizing and upgrading technical education in Kerala. Extensive consultations were held for the preparation of the new curriculum for the University with various stake holders including eminent academicians, distinguished industrialists, faculty members from affiliated institutions and representatives of students. A detailed survey of the existing curriculum in all the universities in Kerala was conducted prior to the preparation of the curriculum for the Technological University. This paper presents certain novel features introduced by the University in the curriculum for the under graduate programmes in engineering.
