Containment and evidence preservation

Containment and evidence preservation are crucial steps in managing a security incident or criminal investigation. Containment involves stopping the incident from spreading further, such as isolating affected systems or areas to prevent damage or data theft. Evidence preservation means carefully collecting, documenting, and securing all relevant materials—like digital files, physical objects, or records—so they remain unaltered and admissible in investigations or court. Together, these steps ensure the situation is controlled and that the evidence remains trustworthy and useful for understanding what happened and taking appropriate action.
