This standard was written to provide a minimum standard for the baseline of Window Server Security and to help Administrators avoid some of the common configuration flaws that could leave systems more exposed. We can simply do this by adding functions under ‘disable functions’ tab in php.ini file. Similar to other Information Security areas, it is necessary to understand website security in a comprehensive way. Also we can specify the source and destination address to allow and deny in specific UDP/TCP ports. Microsoft is dedicated to providing its customers with secure operating systems, such as Windows 10 and Windows Server, and secure apps, such as Microsoft Edge. hardening definition: 1. the act of becoming or making something hard: 2. the act of becoming more severe, determined….

In computing, hardening is usually the process of securing a system by reducing its surface of vulnerability, which is larger when a system performs more functions; in principle a single-function system is more secure than a multipurpose one. Host control management which helps to limit access to specific users and IP address. Now a days, attackers use different type of methods to hack servers, like web-server based attacks, sql injections, attacks via protocols like SSH, HTTP, FTP etc. Rather, a default installed computer is designed for communication and functionality. Ensure Windows Server is up to date with all patches installed. No, server hardening does not mean you need to replace your server racks and cases with tempered steel. Re-configure the BIOS to disable booting from external devices and enable BIOS password & GRUB password to restrict physical access.
