A document detailing a set of practices for users to follow to ensure the confidentiality and integrity of sensitive information is an example of a security guideline.
The statement is correct. A security guideline is a document that provides recommendations on how users should comply with policy and ensure security controls are implemented effectively to protect organizational assets. Guidelines offer advice and suggestions to help in the adherence to formalized security policies, which more strictly dictate required behaviors and procedures. While a guideline is more advisory in nature, a security policy is typically a mandatory set of rules that an organization must follow to be compliant with regulatory requirements or internal best practices.
