// THREAT DETECTION AND DATA PRIVACY TERM
Evidence
In cybersecurity, evidence is any digital information collected from computer systems, networks, or devices that helps investigators understand and prove what happened during a security breach. This data must be handled carefully to be usable in legal or internal disciplinary actions.
TECHNICAL DEFINITION
Cybersecurity evidence refers to digital artifacts and forensically preserved data collected during an incident response (IR) investigation from compromised systems, networks, and storage media. This information, including logs, memory dumps, network traffic, and file metadata, is analyzed to reconstruct attack timelines, identify threat actors, and must maintain a verifiable chain of custody to ensure its integrity and admissibility in legal proceedings.
BACKGROUND
The Cybersecurity and Infrastructure Security Agency (CISA) is a component of the United States Department of Homeland Security (DHS) responsible for cybersecurity and information technology infrastructure protection. It oversees all levels of the federal government and coordinates with U.S. states to improve cybersecurity against private and nation-state hackers. The CISA is headquartered in Arlington, Virginia.
