Abstract
- Cyber security is a critical area in computer systems especially when dealing with sensitive data. At present, it is becoming increasingly important to assure that computer systems are secured from attacks due to modern society dependence from those systems. To prevent these attacks, nowadays most organizations make use of anomaly-based intrusion detection systems (IDS). Usually, IDS contain machine learning algorithms which aid in predicting or detecting anomalous patterns in computer systems. Most of these algorithms are supervised techniques, which contain gaps in the detection of unknown patterns or zero-day exploits, since these are not present in the algorithm learning phase. To address this problem, we present in this paper an empirical study of several unsupervised learning algorithms used in the detection of unknown attacks. In this study we evaluated and compared the performance of different types of anomaly detection techniques in two public available datasets: the NSL-KDD and the ISCX. The aim of this evaluation allows us to understand the behavior of these techniques and understand how they could be fitted in an IDS to fill the mentioned flaw. Also, the present evaluation could be used in the future, as a comparison of results with other unsupervised algorithms applied in the cybersecurity field. The results obtained show that the techniques used are capable of carrying out anomaly detection with an acceptable performance and thus making them suitable candidates for future integration in intrusion detection tools.
