What does 'overt' refer to regarding security practices?

The term 'overt' in the context of security practices signifies actions or measures that are open and obvious to the public, particularly regarding the presence of security personnel or surveillance. When security is overt, it means that individuals are aware of the security measures in place, such as visible cameras, marked security personnel, or clearly identified security checkpoints. This transparency can serve as a deterrent to potential wrongdoing since the visible presence of security can discourage criminal activity simply by its existence.

In contrast, options like hidden identities or undercover work represent covert practices that are not meant to be seen or acknowledged, focusing on secrecy and stealth. Illegal surveillance operations, by nature, aim to evade public awareness and can lead to violations of privacy rights. All of these aspects illustrate the difference between overt measures, which reinforce public safety through visibility and transparency, and covert methods that operate in secrecy.
