Which control involves updating software and systems regularly to mitigate risks?

Regularly updating software and systems is best categorized as a preventative control because it aims to reduce the likelihood of security threats and vulnerabilities before they can be exploited. Preventative controls are proactive measures designed to prevent errors, fraud, and other undesirable events from occurring. By keeping software and systems updated, organizations can address known vulnerabilities, implement necessary patches, and thus minimize the risk of attacks or breaches.

This approach is essential in maintaining the integrity and security of information systems, making it less susceptible to exploitation, ensuring compliance with security policies, and safeguarding sensitive data against potential threats. Regular updates can include applying security patches, upgrading software versions, and enhancing system functionalities, all of which contribute to a more secure operating environment.
