Which measure can management take to prevent malicious software infections?

Management can take proactive measures to prevent malicious software infections, and regularly updating the organization's operating systems is one of the most effective strategies. Keeping operating systems up to date ensures that all security patches, bug fixes, and improvements provided by the software vendors are applied. This helps to close vulnerabilities that could be exploited by malware. Outdated systems are particularly susceptible to attacks due to the known security flaws that malware authors target.

By ensuring that software is current, the organization reduces the risk of infections, as many cyber threats capitalize on unpatched vulnerabilities. Regular updates also often include enhanced security features that bolster defenses against upcoming threats, thereby fortifying the organization’s cybersecurity posture.

While the other options might seem beneficial in isolation, they do not directly address the primary vector for malware infections. For instance, requiring users to reuse passwords or preventing internet access can lead to increased frustration and inadequate security practices. Allowing only known software applications to run can be effective but may restrict necessary business operations unless combined with a comprehensive update strategy.
