Which of the following actions must be performed immediately if unauthorized access occurs?

The action of reporting unauthorized access immediately is crucial for several reasons. First, swift reporting allows for a prompt response, which is essential in mitigating any potential damage that could arise from the breach. Unauthorized access may lead to data theft, vandalism, or other security threats, and timely notification to the right authorities can help contain the situation effectively.

Additionally, immediate reporting can initiate an investigation, allowing security personnel to gather evidence and analyze the breach in real time. This is important for understanding the nature of the unauthorized access and preventing it from happening again in the future.

Delaying action, such as waiting for confirmation from security or notifying management before taking immediate steps, could allow the situation to escalate or worsen. The urgency of the situation demands immediate communication to ensure that measures can be taken to protect sensitive information and maintain the overall security of the premises.
