Surveillance Principle
A principle stating that access must remain under active observation and may be challenged or interrupted dynamically.
Definition
The Surveillance Principle extends control beyond the initial decision. Usage must be monitored continuously, suspicious behavior must be detected, access can be challenged again, and risky sessions can be interrupted in real time. In this model, security is not limited to granting access; it also includes supervising its use.
The Ariovis perspective
Privileged security should begin by reducing standing privilege, governing accounts and automating grants and revocations. Vaults, bastions and session controls are reserved for the use cases that genuinely need them.
