Final answer:
A formal and detailed examination of an operation's areas for potential guest threats refers to a type of security-focused audit, like those used in financial institutions to prevent data breaches.
Step-by-step explanation:
The type of audit being referred to is a formal and detailed examination of an operation's areas to identify potential threats to guests. This kind of audit is typically found in the context of operational security within businesses or organizations. In the setting of a banking institution, for instance, the research conducted by Bruno & Abrahão (2012) highlighted the impact of cognitive effort on the accuracy of decisions concerning information security. High volumes of decisions leading to increased cognitive demand can result in more frequent errors, such as the misidentification of security incidents. This was evident in the case of the Target data breach in 2013, where security warnings were not correctly heeded, having costly consequences for the company.
