| Titre | Windows Server 2019 OS hardening |
| Texte | This blog was written by an independent guest blogger. Windows Server 2019 ships and installs with an existing level of hardening that is significantly more secure compared to previous Windows Server operating systems. Gone are the bloat of Xbox integration and services and the need for third-party security solutions to fill security gaps. Operating System (OS) hardening provides additional layers of security and preventative measures against both unauthorized changes and access. Hardening is critical in securing an operating system and reducing its attack surface. Be careful! If you harden an operation system too much, you risk breaking key functionality. Hardening approach Harden your Windows Server 2019 servers or server templates incrementally. Implement one hardening aspect at a time and then test all server and application functionality. Your cadence should be to harden, test, harden, test, etc. Mistakes to avoid Reducing the surface area of vulnerability is the goal of operating system hardening. Keeping the area as small as possible means avoiding common bad practices. Do not turn off User Access Control (UAC). You should move the UAC slider to the top: Always notify. The few extra clicks to make while trying to install a new application or change system settings might prevent system compromise in the future. Do not install Google Chrome, Firefox, JAVA, Adobe Flash, PDF viewers, email clients, etc. on your Windows Server 2019 operating systems unless you have an application dependency for these applications. Do not install unnecessary roles and features on your Windows Server 2019 servers. If you need to install a role such as IIS, only enable the minimum features you require and do not enable all role features. Do not forget to fully patch your Windows Server 2019 operating system and establish a monthly patch window allowing you to patch and reboot your servers monthly. Hardening Windows 2019 Server Core As a foundation to Windows Server 2019, the Core version of Windows Server 2019, should be installed. This version is Windows 2019 Server Core. Server Core removes the traditional GUI interface to the operating system and provides the following security benefits. • Server Core has a smaller attack surface than Server with a GUI • Requires fewer software updates and reboots • Can be managed using new Windows Admin Center • Improved Application Compatibility features in Windows Server 2019 Traditional Windows administrators may be apprehensive running Server Core due to a lack of PowerShell familiarity. The new Windows Admin Center provides a free, locally deployed, browser-based app for managing servers, clusters, hyper-converged infrastructure, and Windows 10 PC’s. Windows Admin Center comes at no additional cost beyond Windows and is ready to use in production. You can install Windows Admin Center on Windows Server 2019 as well as Windows 10 and earlier versions of Windows and Windows Server and use it to manage servers and clusters running Windows Server 2008 R2 and later. Secure the Local Administrator Account Local Administrator Password Solution (LAPS) If Windows Server does get compromised, the attacker will quickly try to move laterally across your network to find highly valuable systems and information.
