Operating System Security Guidelines
■
Do not create passwords that contain a word or string that is easily discovered by a simple
Internet search.
■
Do not allow users to reuse the same password across multiple systems.
■
Do not allow users to reuse old passwords.
Change passwords on a regular basis. This helps to prevent malicious activity and ensures that
passwords adhere to current password policies.
