Final answer:
The statement that security assessments should be conducted at the same time each week is false; assessments should be performed at various times to ensure a thorough evaluation of security measures.
Step-by-step explanation:
The statement that security assessment inspections should always be conducted at the same time and day of the week, when the building and grounds are unoccupied, is false. For security assessments to be effective, they need to be conducted at various times and days to gain a comprehensive understanding of the security challenges a building may face under different conditions.
It is essential to conduct the survey during different times of the year, using various methods, and on different days of the week to identify any potential security issues that may not be present at a certain time or may be influenced by different factors, such as seasonal changes or varying traffic patterns.
