Analysis of Overall Support & Compatibility Status: Windows Server 2016 is currently in its extended support phase, meaning it receives critical security updates but no new features, non-security bug fixes, or design changes. This status necessitates careful planning for organizations, as it approaches its end-of-life in early 2027. Compatibility with modern hardware is generally good, but newer server technologies and features are optimized for later Windows Server versions. Organizations should consider migration strategies to newer, fully supported versions like Windows Server 2019 or 2022 to ensure access to comprehensive support and the latest innovations.

Security Status

  • Security Features:
    • Credential Guard: Protects user credentials from compromise by isolating the Local Security Authority (LSA) in a virtualized space (Isolated User Mode).
    • Device Guard: Prevents malware by enforcing code integrity policies, ensuring only trusted applications can run. It includes Configurable Code Integrity, VSM Protected Code Integrity, and Platform and UEFI Secure Boot.
    • Shielded Virtual Machines (VMs): Protects Generation 2 VMs from a compromised fabric using BitLocker encryption, virtual TPM (vTPM), and Host Guardian Service (HGS). Shielded VMs can only run on attested, approved hosts.
    • Host Guardian Service (HGS): Validates Hyper-V hosts to ensure they are authorized to run Shielded VMs, protecting against malicious administrators and compromised hosts.
    • Windows Defender: Built-in anti-malware protection, enabled by default without a GUI, providing real-time protection and regular definition updates.
    • Just Enough Administration (JEA) and Just-in-Time (JIT) Administration: Limits administrative privileges and access time, reducing the attack surface from compromised credentials.
    • Control Flow Guard: Helps protect against memory corruption vulnerabilities.
    • Secure Boot: Part of Device Guard, ensures that only trusted firmware and operating system components load during startup.
    • Virtual Secure Mode (VSM): Creates isolated memory regions to protect critical system processes and data.
  • Known Vulnerabilities: As an operating system, Windows Server 2016 has had numerous Common Vulnerabilities and Exposures (CVEs) identified over its lifecycle, including categories such as information disclosure, privilege escalation, and remote code execution. Examples include vulnerabilities in Windows GDI, SMBv2, and the Windows kernel. Microsoft regularly releases security updates to address these.
  • Blacklist Status: Not applicable to an operating system in general.
  • Certifications: Enterprise operating systems like Windows Server 2016 typically undergo various industry and government security certifications, though specific certifications are not detailed in the provided data.
