A centralized antivirus system that checks for latest updates before network access is an example of?

A centralized antivirus system that checks for the latest updates before allowing network access functions primarily as a corrective control. Corrective controls are designed to prevent, detect, and correct issues that arise within a system. In this context, the antivirus system not only detects potential threats but also corrects them by ensuring that the most recent updates and signatures are applied before a device connects to the network. This proactive measure helps in minimizing vulnerabilities and addressing any identified threats immediately.

The role of the centralized antivirus system is to ensure that any malware or virus is mitigated effectively by keeping the system up to date, thus preventing potential harm to the network and ensuring that all endpoints comply with security policies. This aligns well with the definition of corrective controls, which aim to restore systems to a normal operating state following a security incident or vulnerability discovery.

In summary, the primary function of this centralized antivirus system is to correct weaknesses by ensuring that devices are updated, making the choice of corrective control the most fitting option for this scenario.
