Which of the following is an example of data security?

Automatic logoff after inactivity is an example of data security because it serves to protect sensitive data by ensuring that user sessions are terminated after a predefined period of inactivity. This mechanism helps prevent unauthorized access to data if a user leaves their workstation unattended. Implementing automatic logoff adds a layer of security by mitigating the risk of unauthorized individuals gaining access to sensitive information and systems.

In the context of data security, this practice is essential as it reinforces the principle of safeguarding information. Users are less likely to inadvertently expose confidential data to potential threats, including data breaches, when proper proactive measures like automatic logoff are employed.

While contingency planning, fire protection, and card key access can contribute to overall safety and security, they address different aspects. Contingency planning focuses on preparing for emergencies or disruptions, fire protection is aimed at physical risks to premises, and card key access helps regulate who can physically enter secure areas. However, automatic logoff directly targets the cybersecurity aspect of protecting data from unauthorized access during active sessions.
