Linux Admin & DevOps
Service description
When a breach is unfolding, the worst thing you can do is guess. I step in during and after security incidents to bring order to the chaos: first I help you contain the threat so it stops spreading, then I reconstruct exactly what happened, and finally I hand you a plan so it never happens the same way twice. I work calmly under pressure, keep you informed at every step, and never pull a system offline without explaining the trade-off first. My goal is simple: stop the bleeding, understand the wound, and make you stronger than you were before.

My process starts with containment and triage. I isolate compromised hosts, revoke abused credentials, and preserve volatile evidence before it disappears. Then I move into deep analysis: I examine system, network, and application logs, capture and study memory and disk images, follow the attacker's timeline hop by hop, and identify the initial entry point along with everything they touched. I handle all evidence with a documented chain of custody, so if you ever need it for insurance, regulators, or legal action, it holds up. Every finding is written in plain language, not jargon, so both your engineers and your leadership can act on it.

You finish with a full remediation report: what happened, how, which data and systems were affected, what I did to contain it, and a prioritized list of fixes to close the gaps for good. I only perform defensive, authorized work on systems you own or are permitted to investigate, and I will ask for written scope before touching anything.
