containment
termops culturesecurity
Limiting how much a fault affects, without addressing why it happened.
Failing over, disabling a feature, blocking a source, isolating a segment: none of these repair anything, they put a boundary around the damage. Most incidents end at containment, which is the normal shape of the work - but reports that call the result “resolved” rather than “bounded” describe a problem that is still live.
