Which practice helps maintain system health and improve security?

Regular password changes are an important practice for maintaining system health and enhancing security. This approach helps mitigate the risk of unauthorized access to systems and sensitive data. Over time, passwords can be compromised through various means, such as phishing, data breaches, or social engineering tactics. By implementing a policy for regular password updates, organizations can reduce the window of opportunity for attackers to exploit stale credentials.

Additionally, this practice encourages users to adopt stronger password habits and increases their awareness of security issues. Strong, continuously updated passwords, combined with other security measures such as multi-factor authentication, create a more robust defense against cyber threats.

Network performance analysis, while valuable for understanding and optimizing the efficiency of a network, does not directly address the security aspects nor help in preventing unauthorized access. Legacy software usage often poses significant security risks because older software may not receive regular updates or patches, leaving vulnerabilities exposed. Annual budget audits are crucial for financial oversight but do not directly contribute to the improvement of system health or security.
