What should an operator do if in doubt regarding system security?

When operators are uncertain about system security, the most appropriate action is to notify the IDACS Support Desk regarding any attempted breaches. This is crucial because the Support Desk can provide immediate assistance and investigate any potential security issues more thoroughly. They are equipped with the necessary resources and expertise to assess the situation and take the right steps to safeguard the system and the integrity of the data it holds.

In scenarios involving security concerns, it is vital to ensure that any doubts are addressed through established channels rather than handling them independently. This helps maintain overall system security and prevents potential risks, as every operator's actions can have implications for the entire system. Communication with the support desk allows for prompt action and documentation of the incident, which is essential for future reference and risk management.
