Incident Response

Incident response (IR) is the process a team runs once something has gone wrong. The widely used SANS model breaks it into phases: preparation, identification, containment, eradication, recovery, and lessons learned. Each phase has a goal. Containment stops the bleeding, eradication removes the attacker's access, and recovery restores service, all while the team preserves evidence for later analysis and any legal need.

The discipline matters because the early hours of a breach decide its cost. A team that has playbooks, defined roles, and ready access to logs can isolate a compromised host and cut off the attacker quickly. A team improvising under pressure loses time, destroys evidence, and often misses the foothold the attacker left to return through.

IR leans on the rest of the security operation. A security operations center raises the alert, a SIEM supplies the logs and correlation that reconstruct the timeline, and confirmed indicators of compromise tell responders what to search for across the estate. Findings from an incident often seed proactive threat hunting to check whether the same activity reached other systems.

In a Trickest workflow, you automate the repeatable steps: enrich an alert's indicators, sweep assets for matches, and gather host and network context so responders open an investigation with the facts already assembled.
