What this chapter explains
- Management concept and decision mechanism
- Balance urgent action and evidence
Management concept and decision mechanism
Containment limits ongoing harm. Options can differ in reversibility, speed, evidence effect, service interruption and safety consequences. Use delegated authority and the incident’s urgency; preserving evidence is valuable but not an absolute reason to continue avoidable harm. Record the evidence available, decision-maker, rationale, expected impact and reassessment point. Coordinate workarounds where possible. Containment does not necessarily remove the cause, and a temporary restriction should not be silently treated as final remediation. Validate that the action limits the intended path without creating an unacceptable new consequence.
Balance urgent action and evidence
Containment should limit harm while considering service impact, attacker activity, and the need to investigate. Use authorized procedures and appropriate specialists. In some situations rapid isolation is essential; in others an indiscriminate shutdown could create additional operational or safety consequences.
Preserve relevant records and document who collected, accessed, or transferred them. Follow the organization's evidence-handling process and obtain specialist advice when needed. Do not promise that a particular collection method will satisfy every legal proceeding or jurisdiction.
Worked example
An authorized commander isolates a server issuing harmful instructions, preserves feasible evidence and coordinates a controlled business workaround.
Check your understanding
Why is containment not the same as eradication?
Show explanation
Containment limits harm or access; the underlying cause, persistence and exposed identities may still require correction.
