What should be prioritized if unauthorized access to restricted areas is suspected?

When unauthorized access to restricted areas is suspected, reviewing personnel access and training is critical. This action allows for an immediate understanding of who has access to sensitive areas and whether they have received the appropriate training and clearance. By evaluating who is authorized versus who has actually accessed these areas, it helps to identify any irregularities or breaches in protocol. Moreover, ensuring that personnel are properly trained on security policies and procedures can help prevent future incidents.

Additionally, addressing access issues helps to reinforce accountability and ensures that only those who are qualified can enter restricted zones. This step is essential in maintaining the integrity of security systems and safeguarding sensitive information or assets.
