The process of securing, protecting, and maintaining the integrity of digital and physical evidence to ensure its admissibility in legal proceedings or internal investigations.
Evidence preservation for insider threats must occur rapidly while maintaining employee rights and business operations. This includes creating forensic images of systems, preserving logs and audit trails, documenting user activities, and maintaining chain of custody records. Organizations must have predefined procedures for evidence collection that comply with legal requirements and can withstand court scrutiny. Proper preservation enables successful prosecution of malicious insiders and supports disciplinary actions while protecting the organization from wrongful termination claims.
