OISF/suricata
Mar 2016 - May 2016
Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine developed by the OISF and the Suricata community.
Role in this project:Back-end & Security Engineer
Back-end & Security EngineerContributions:18 commits, 20 PRs, 19 comments in 2 months
Contributions summary:Justin primarily contributed to the integration and implementation of the Hyperscan regex engine within the Suricata intrusion detection system. They added a new MPM (Multi-Pattern Matcher) implementation leveraging Hyperscan, including database building, scratch space management, and search functionality. The user also updated the SPM (Single Pattern Matcher) API to support multiple implementations and added an SPM Hyperscan implementation. Further, they made several code changes to the existing content matching features in `detect-engine` and `detect-content` to integrate with the newly developed SPM API.
