When detecting malwares, which process is crucial to ensure network safety?

Regular updates of antivirus definitions are essential in the fight against malware for several key reasons. Malware evolves rapidly, with new variants emerging almost daily. Antivirus solutions rely on signature-based detection methods to identify known threats. When antivirus definitions are regularly updated, the software can recognize and mitigate new malware strains that might otherwise infiltrate the network.

Moreover, updated definitions often include patches for vulnerabilities that could be exploited by malware, thereby enhancing the overall security posture of the network. Cyber threats are dynamic, and an organization's defenses must be kept current to effectively respond to these challenges, making this practice a vital element of network safety.

The other options do not contribute to improving network security. For instance, rebooting all network devices may temporarily disrupt services but does not address the underlying threat posed by malware. Allowing unrestricted access to all users actually increases risk, as it can lead to unauthorized actions and exposures. Disabling all security measures would leave the network completely vulnerable to attacks. Therefore, keeping antivirus definitions up to date is the most effective approach to safeguard against malware.
