OS Hardening (Linux and Windows)
Operating System (OS) hardening is the process of securing an OS by reducing its attack surface and minimizing its vulnerability to cyber threats. It involves configuring and optimizing the system settings, software, and services to make it more resilient to malicious attacks. Linux and Windows are two popular operating systems that require hardening to enhance their security.
Linux is a popular OS used for servers, embedded systems, and mobile devices. It has built-in security features such as access controls, firewalls, and encryption tools. However, additional hardening measures such as disabling unnecessary services, restricting user privileges, and implementing security patches are necessary to reduce the risk of cyber threats. Security-focused Linux distributions such as Kali Linux and Parrot Security OS come pre-installed with many security tools and features for enhanced protection.
Windows is the most widely used desktop OS in the world, and it is often targeted by hackers due to its popularity. Windows hardening involves configuring security settings, disabling unused services, and installing security updates and patches regularly. Microsoft provides many security tools such as Windows Defender and Microsoft Security Essentials to protect Windows systems from malware and cyber attacks. In addition, third-party security tools such as anti-virus software and firewalls can be used for added protection. Regular backups of critical data are also essential to minimize the damage caused by a successful cyber attack.
