Heuristic is the technique that best describes antivirus software that detects viruses by watching anomalous behavior. Heuristic is a method of virus detection that analyzes the behavior and characteristics of the program or file, rather than comparing it to a known signature or pattern.
Heuristic can detect unknown or new viruses that have not been identified or cataloged by the antivirus software. However, heuristic can also generate false positives, as some legitimate programs or files may exhibit suspicious or unusual behavior.

The proper term for this trusted facility management concept is "Two-man Control", it means that two people must work and approve each others work to provide increased security and eliminate the possibility of one of them to hurt the company. For example they can only make changes to the system if both of them authenticate with their retina at the same time at the data center and enter their secret password This kind of work fashion is only used in highly secure environments, its not very common.

Especially high visibility should be afforded the formal issuance of
IT security policy. This is because nearly all employees at all levels
will in some way be affected, major organizational resources are
being addressed, and many new terms, procedures, and activities
will be introduced.
Including IT security as a regular topic at staff meetings at all levels of the organization can be helpful. Also, providing visibility through such avenues as management presentations, panel discussions,
guest speakers, question/answer forums, and newsletters can
be beneficial.
