A review on signature-based detection for network threats

摘要

Nowadays, the attacks on the Internet are becoming more complex, advanced and concealed. A large number of security threats arise. The signature-based detection technology is efficient and simple which is widely used for malicious codes detection system. In this paper, we firstly focus on the principle of the method, and summarize the specific steps to implement it, especially feature extraction, codes preprocessing, and matching algorithms. Then we discuss the features and improvements for the method, and the application. Finally, more detection technologies are introduced.
