Which security control focuses on hardening the digital vault server?

The focus of hardening the digital vault server is crucial for ensuring the security and integrity of sensitive information stored within CyberArk's systems. Hardening refers to the process of securing a system by reducing its surface of vulnerability. This involves configuring the server to minimize the potential points of attack and eliminating unnecessary services that could be exploited by malicious actors.

By isolating and hardening the digital vault server, organizations can impose strict access controls, enforce secure configurations, and regularly monitor for unusual activities. This dedicated approach to securing the vault server specifically targets the critical nature of the data contained within it, ensuring that it is well-defended against potential threats.

Other options, while important to cybersecurity practices, do not specifically address the hardening of the digital vault server. Using firewalls enhances network security but does not inherently involve the server's internal configurations or settings. Regular password changes are a crucial security measure but pertain primarily to user accounts rather than the server itself. Employee training on security awareness is vital for a broader security culture but does not directly affect the technical hardening of servers. Each of these practices contributes to overall security but does not singularly address the specific hardening process essential for the digital vault server.
