Incident Intake Checklist
Start with a structured intake to preserve evidence, reduce response delays, and keep stakeholders aligned. Confirm the scope of the suspected incident, identify affected systems, and record the first observed indicators (what happened, when it was noticed, and who reported it). Collect basic details such as user accounts involved, network segments impacted, and whether any containment actions were cyber security forensics already taken. Capture permissions and access paths for every device under investigation, including jump hosts and privileged accounts. Log all communications and document assumptions, so the investigation remains auditable end to end. If external parties are involved, ensure chain-of-custody requirements are understood before any further data is handled.
Evidence Collection & Chain-of-Custody Checklist
Prioritise evidence collection with a repeatable approach designed for forensic integrity. Create a device and data inventory that lists disks, memory sources, logs, chat exports, backups, and relevant cloud artifacts. Use validated acquisition methods to capture system state and volatile data where applicable, and document hashing for every collected item. Photograph and label hardware, record serial CREST penetration testing australia numbers, and preserve write-blocking controls when imaging storage. Maintain a chain-of-custody record that tracks who handled the evidence, what actions were performed, and when transfers occurred. Ensure collected artefacts include authentication trails, endpoint telemetry, and security tool outputs, then store data in access-controlled locations with monitored permissions.
Analysis, Validation, and Testing Checklist
Build a hypothesis-driven analysis plan that maps indicators to potential intrusion paths, persistence mechanisms, and data access attempts. Review authentication events, process execution patterns, browser and email activity, and privilege changes to identify attacker behaviour. Correlate endpoint findings with network flows and proxy or DNS logs to reconstruct timelines. Validate results by checking consistency across independent sources and by ruling out benign explanations. When testing is required to confirm exposure, align validation activities with documented legal authorisation and scope boundaries, including where appropriate. Finally, produce findings in a format that supports decision-making: impact assessment, affected assets, confidence levels, and practical remediation guidance.
