Knowra Incident response Incident response Incident response is an organized process for identifying, containing, investigating, and recovering from security incidents. It coordinates technical actions, decisions, and communications to limit harm and restore operations.
Security incident : An event that compromises or threatens the confidentiality, integrity, or availability of information or systems. This is the condition that activates an incident response process.
Computer security : The protection of computer systems and information against unauthorized access, damage, or disruption. Incident response is one operational part of this broader protective discipline.
Incident response plan : A documented set of roles, procedures, and decision paths for handling security incidents. The plan turns response responsibilities into agreed steps before an incident occurs.
Vulnerability management : The ongoing process of finding, prioritizing, and remediating security weaknesses in systems and software. It reduces weaknesses continuously, whereas response handles events that have become incidents.
Chain of custody : A documented record of who collected, handled, transferred, or examined evidence and when. A reliable chain of custody supports confidence in evidence gathered during response.
Incident detection : The identification of events that may indicate a security incident. Detection supplies the signals that start triage and response.
Security operations center : A team and facility that monitors systems, investigates alerts, and coordinates security operations. A security operations center often detects incidents and coordinates the first response.
NIST Cybersecurity Framework : A framework of cybersecurity outcomes organized around Govern, Identify, Protect, Detect, Respond, and Recover. Its Respond and Recover functions place incident handling within broader risk management.
Threat hunting : The proactive search for signs of malicious activity that automated alerts may have missed. Hunting seeks hidden threats; incident response coordinates action once a suspected incident is handled.
Security breach notification laws : Laws requiring organizations to notify specified parties after certain personal information breaches. Incident findings can trigger legal duties to notify regulators or affected people.
