Description

When implementing security solutions, there are many ways to integrate a blocklist and improve the detection of suspicious/malicious activity. If there exists many blocklist available online, sometimes their content does not fit exactly with your expectation (false positives, too complex, etc). So, I implemented my own blocklist based on a REST API. This allow me to interconnect it with many tools/scripts/devices to fetch or update its content. In this presentation, I’ll explain how and why I implemented it with only one goal : automation & improvement of the security perimeter.
