Abstract

Over the last two decades, computer and network security has become a main issue, especially with the increase number of intruders and hackers, therefore systems were designed to detect and prevent intruders. This chapter per the authors investigated the most important design approaches, by mainly focusing on their collecting, analysis, responding capabilities and types of current IDS products. For the collecting capability, there were two main approaches, namely host- and network-based IDSs. Therefore, a combination of the two approaches in a hybrid implementation is ideal, as it will offer the highest level of protection at all levels of system functions. The analysis capability of an IDS can be characterised by the misuse and anomaly detection approaches. Therefore, a combination of the two approaches should improve the analysis capability of an IDS i.e. hybrid of misuse and anomaly detection.
