For a secure server environment, which of the following practices is recommended?

Regularly auditing server access and permissions is a critical practice for maintaining a secure server environment. This process involves reviewing user accounts, roles, and their associated permissions to ensure that only authorized users have access to sensitive data and resources. By identifying any unauthorized access or excessive permissions, organizations can mitigate the risk of data breaches, insider threats, and non-compliance with regulatory requirements.

Additionally, regular audits enable administrators to keep track of changes in access patterns over time, identify potential security vulnerabilities, and ensure that the principle of least privilege is being applied effectively. This practice enhances the overall security posture of the server environment and contributes to the safeguarding of critical assets.

The other practices mentioned in the choices are less secure and can expose the server environment to risks. Allowing all users to install software can lead to unverified applications being introduced, which may contain malware. Configuring firewalls after deployment leaves the server vulnerable during the initial setup phase when exposure to threats is heightened. Using default passwords for devices is a security risk, as these passwords are commonly known and easily exploited by attackers. Thus, the practice of regularly auditing server access and permissions stands out as a proactive security measure in safeguarding server environments.
