For Threat containment we have a term and definition in Computer Virus.

A measure of how well current antivirus technology can keep this threat from spreading. As a general rule, older virus techniques are generally well-contained; new threat types or highly complex viruses can be more difficult to contain, and are correspondingly more a threat to the user community. The measures are Easy (the threat is well-contained), Moderate (the threat is partially contained), and Difficult (the threat is currently uncontainable).
