Cyber attacks are increasingly common in today’s world. Generally speaking, attacks or intrusions can be identified by comparing with known attack signatures or by using anomaly detection. Using signature-based methods is really effective in identifying known attacks; but they cannot identify new attacks. Hence, the importance of anomaly detection.

A honeypot aims to lure attackers in a computer network. You can read more about honeypots at But honeypots are almost never standalone security measures. We look at ways of increasing honeypot performance.
