Re-imaging compromised servers before capturing volatile memory, authentication logs, and persistence artefacts destroys the evidence needed to understand how the intruder entered—and whether they still hold access elsewhere.
Avoiding Evidence Destruction During Containment
During a high-pressure security incident, the instinct is to wipe affected machines and restore from backup immediately. Without first isolating the host and preserving volatile artefacts, organisations cannot confirm the full blast radius, satisfy regulatory reporting enquiries, or verify that backdoors have been eradicated.
Reconstructing the Intrusion Timeline
Nexa Cyber Security forensic specialists correlate endpoint artefacts, directory authentication logs, cloud audit trails, and suspicious binaries to establish a factual timeline from initial access to lateral movement and data access.
Translating RCA Findings into Durable Controls
An incident is only truly resolved when the underlying weakness is closed. Our Root Cause Analysis deliverables map every technical failure to specific preventive, detective, and recovery controls so leadership can track remediation to verified closure.
