How It Enhances Server Security
By enabling a secured-core server, administrators gain access to a more resilient defense architecture. It minimizes the attack surface by ensuring that each layer of the server’s environment is verified and secure, which drastically reduces the risks posed by firmware and boot-level threats.
Hardware Root-of-Trust
The concept of hardware root-of-trust refers to hardware components that act as the foundation for a trusted computing environment. This hardware trust is essential for establishing a chain of trust throughout the server lifecycle.
Definition and Importance
The hardware root-of-trust is built into the server’s physical hardware and is responsible for validating the integrity of the system. It ensures that only authorized software and firmware are allowed to run, creating a baseline of security that is difficult for malicious actors to bypass.
How Windows Server 2022 Leverages Hardware Root-of-Trust
Windows Server 2022 security features leverage hardware root-of-trust through integration with trusted platform modules (TPM) and secure boot technologies. TPMs provide cryptographic keys that safeguard sensitive information and ensure system integrity. These mechanisms provide a secured environment from boot through runtime.
Impact on Overall Security
By incorporating hardware root-of-trust, Windows Server 2022 security guarantees that the system starts in a secure state and maintains integrity throughout its operation. This significantly reduces the possibility of successful firmware-based attacks, which are often undetectable by traditional software security solutions.
Virtualization-based Security (VBS)
Virtualization-based Security (VBS) is another innovative component of security features in Windows Server 2022 designed to provide protection against a wide range of cyber threats, especially those targeting virtual machines.
Overview of VBS
VBS uses hardware virtualization to isolate specific parts of the system and create a secure environment. It uses Hyper-V, a Microsoft hypervisor, to run code in a virtualized environment separated from the main operating system.
Features and Functionalities
VBS incorporates features such as Credential Guard and Hypervisor-Enforced Code Integrity (HVCI). Credential Guard protects credentials from theft by isolating them in a secure, virtual environment. HVCI ensures that only trusted code can be executed in the kernel of the system, preventing malicious software from compromising the operating system.
How VBS Protects Against Common Threats
VBS isolates critical data and processes from the rest of the operating system, making it much harder for attackers to compromise sensitive components. This isolation protects against attacks such as credential theft, memory corruption, and malware execution, which are common in enterprise environments.
Secure Connectivity
In today’s world, ensuring secure communication between servers, clients, and services is crucial. Windows Server 2022 security features introduce several updates that enhance secure connectivity.
New Features for Secure Connectivity
Windows Server 2022 comes with several updates that enhance secure connectivity. Key among these is the implementation of Transport Layer Security (TLS) 1.3, which provides enhanced encryption, security, and performance.
Implementation of TLS 1.3
TLS 1.3, the latest version of the cryptographic protocol, has been integrated into Windows Server 2022 to provide more robust encryption for data in transit. It removes outdated encryption algorithms and introduces features such as forward secrecy, ensuring that even if encryption keys are compromised in the future, past communications remain secure.
Improved DNS Client Security
Windows Server 2022 also includes updates to the DNS client to improve its security. It supports DNS-over-HTTPS (DoH), which encrypts DNS queries and ensures privacy. This prevents attackers from intercepting and tampering with DNS traffic.
Advanced Threat Protection
