What is one vital step for hardening a PSMP server?

Hardening a PSMP (Privileged Session Manager Proxy) server is crucial to ensure its security and reliability within an organization. One of the most vital steps in this process is performing software updates. Keeping the software updated is essential because it includes important security patches that address vulnerabilities, fixing issues that could be exploited by attackers. CyberArk and other software vendors regularly release updates to combat emerging threats and enhance functionality, so staying up to date mitigates risks associated with known vulnerabilities.

While other steps, such as disk cleanup, installing antivirus software, and running performance tests, can contribute to the overall health and security of a server, they do not directly address the critical need for security updates and patch management. Disk cleanup improves system performance but does not necessarily enhance security. Installing antivirus software protects against malware but does not cover all types of vulnerabilities that can be exploited on the server. Running performance tests can be useful for assessing system efficiency but does not strengthen the server's defenses against threats. Therefore, prioritizing software updates is the most effective way to enhance the security posture of a PSMP server.
