OT IR differs from IT IR. Safety supersedes investigation. Containment can mean physical action, not just network isolation.
OT IR differs from IT IR. Safety supersedes investigation. Containment can mean physical action, not just network isolation.
Differences
- Safety first; never an action that endangers people or environment
- Operations team has veto on technical decisions
- Evidence preservation often impossible (PLCs don’t log; HMI logs sparse)
- System restoration may require physical access
- Recovery from backup unusual; OT doesn’t backup like IT
