Blueprint 06

SOC/IR Evidence Package

Incident response evidence bundles with tamper-evident chain-of-custody records for forensic analysis. Produce sealed, signed packages with cryptographic integrity proofs suitable for audits and disputes.

Security Operations
01

Target System.

Security Operations Centers (SOC), Incident Response (IR) teams, digital forensics investigators, and legal/compliance teams requiring tamper-evident evidence for breach investigations, litigation support, and regulatory reporting.

02

Threat Model.

  • Evidence tampering during incident investigation
  • Chain-of-custody breaks during handoffs
  • Timestamp manipulation in log files
  • Incomplete evidence collection for legal proceedings
  • Attribution challenges with contested evidence
