How should non-issued NSS tokens be protected from theft?

Non-issued NSS tokens should be stored in a secure manner to prevent unauthorized access and potential theft. Storing them in a safe location that is authorized for sensitive or classified material ensures that the tokens are protected according to established security measures. This kind of location typically has access controls and physical security measures in place to protect sensitive information and assets, which reduces the risk of theft or misuse.

The other options do not provide adequate protection for sensitive materials. Keeping tokens in an unlocked drawer exposes them to easy access by anyone, while holding them with a trusted colleague may lead to loss of accountability and security lapses. Storing them at home fails to provide the necessary safeguards and may lead to threats external to the workplace. Hence, the secure storage of non-issued NSS tokens must align with appropriate protocols to ensure their integrity and confidentiality, making the secure location authorized for sensitive or classified material the correct approach.
