Johana was working on a confidential project on her laptop.

One of the most basic and important security guidelines for laptop users is to always log off or lock the system when unattended. This prevents unauthorized access to the system and the data stored on it by anyone who might have physical access to the laptop. Logging off or locking the system requires a password or other authentication method to resume the session, which adds a layer of protection to the laptop. Johana failed to comply with this security guideline, as she left the system active with the project file open and went for a coffee break, allowing Bob to access her system and modify the project file.References:
