Server hardening is the process of securing a server by reducing its attack surface and minimizing vulnerabilities that could be exploited by malicious actors. This involves implementing various security measures to enhance the server's defenses and protect it from unauthorized access, data breaches, and other cyber threats. Server hardening typically includes activities such as disabling unnecessary services, applying security patches and updates regularly, configuring strong authentication mechanisms, setting up access controls, and implementing encryption to safeguard data in transit and at rest.

By hardening a server, organizations can reduce the risk of security incidents and better protect their sensitive information and assets. This proactive approach helps to enhance the overall security posture of the server infrastructure and mitigate potential security risks. Server hardening is essential for ensuring the confidentiality, integrity, and availability of data stored on the server and maintaining compliance with industry regulations and security best practices. Overall, server hardening is a critical aspect of cybersecurity that helps organizations strengthen their defenses and safeguard their digital assets from cyber threats.
