Which personnel security measure is recommended for access to controlled substances?

• A. Don't allow access to individuals with felony convictions related to controlled substances
• B. Allow access to anyone with a badge
• C. Share access keys among staff
• D. Store access keys under a doormat

Answer: (A)

Access to controlled substances should be restricted to personnel who have been properly vetted and authorized. Excluding individuals with felony convictions related to controlled substances directly reduces the risk of diversion or theft by someone with a relevant history, and it supports regulatory compliance and organizational security policies. It also strengthens accountability because access is granted only to those who meet the required background standards. In contrast, granting access to anyone with a badge offers no assurance of trustworthiness, sharing access keys among staff destroys individual accountability and creates multiple failure points, and storing keys in an obvious place like under a doormat is an easy target for theft.
