As the Mac OS operating programs of Mac OS X and macOS are determined by Unix, these running programs are far better catered to while in the IDS entire world than in other application classes.
Like one other open up-source devices on this checklist, such as OSSEC, Suricata is excellent at intrusion detection although not so terrific at displaying outcomes. So, it really should be paired that has a procedure, for example Kibana. If you don’t have The boldness to stitch a process collectively, you shouldn’t go for Suricata.
