Protecting Infrastructure with Windows Server 2019 Standard: Security Features and Protocols

Securing IT infrastructure is a critical task for any organization. Windows Server 2019 Standard offers a broad array of features and tools to assist in safeguarding data, applications, and networks from modern cyber threats. Let’s delve into the key security capabilities available in this edition.


Protection Against Malware and Zero-Day Threats

IT infrastructure security remains a top priority for organizations. Windows Server 2019 Standard includes several advanced technologies to shield servers and endpoints from these threats:

  • Windows Defender Antivirus: Provides continuous protection against viruses, spyware, and other threats in real-time, utilizing a blend of signature-based and heuristic analysis to detect and thwart malicious files and processes.
  • Windows Defender Exploit Guard: It comprises four components aimed at reducing system vulnerability:
    • Attack Surface Reduction (ASR);
    • Controlled folder access;
    • Network protection;
    • Exploit protection.
  • Control Flow Guard: Aids in preventing exploitation of memory vulnerabilities, such as buffer overflow, by embedding integrity checks into compiled code.

The integration of these technologies ensures comprehensive protection against a wide range of malware and attack methods. With automatic updates and cloud threat analytics, servers running Windows Server 2019 Standard can effectively counter even the most sophisticated threats.

Strengthening Credential Protection

Credentials, such as passwords and access tokens, serve as keys to corporate resources and sensitive data. Windows Server 2019 Standard offers advanced security features to safeguard these credentials:

  • Credential Guard: Utilizes virtualization to isolate and protect NTLM, Kerberos, and domain credential secrets, helping to prevent credential theft through Pass-the-Hash or Pass-the-Ticket attacks.
  • Remote Credential Guard: Provides protection for credentials during remote access to systems via RDP. It encrypts credentials on the client side and transmits only the session ephemeral key to the server, thus preventing credential theft on the server.
  • Device Guard: Enables restriction of application execution to trusted code signed with certificates, file hashes, or Windows directories, thereby preventing the execution of malicious or unwanted software.

Finally, the Windows Server 2019 Standard includes a range of security enhancements for the Kerberos authentication protocol. Support for Constrained Delegation allows for limiting the rights that can be granted to a specific service, reducing the risk of credential compromise on intermediary servers. Dynamic Access Control enables defining access policies based on user attributes, devices, and resources, providing more precise access management.

By leveraging these security features, organizations can significantly reduce the risk of credential theft and misuse. Through isolating authentication secrets, applying strict application control, and implementing enhanced authentication protocols, Windows Server 2019 Standard aids in safeguarding corporate resources and data from unauthorized access.

Secure Network Protocols

Windows Server 2019 Standard supports various secure network protocols to protect traffic within and outside the organization:

  • Datagram Transport Layer Security (DTLS): Provides encryption and authentication for UDP traffic, compatible with protocols relying on UDP, such as RADIUS, TFTP, SNMP.
  • TLS 1.3 Support: Enhances performance and security for secure web communications, eliminating obsolete features like SHA-1 and RC4, while adding new capabilities such as protection against downgrade attacks.
  • Secure Shell (SSH) Protocol: Enables secure remote management of Windows servers through an encrypted channel. The built-in SSH server in Windows Server 2019 ensures compatibility with standard SSH clients and supports key-based authentication.

In addition to these protocols, Windows Server 2019 Standard supports a variety of other secure networking technologies, such as IPsec, VPN, DirectAccess, and Software Defined Networking (SDN). By utilizing these tools, administrators can segment networks, apply granular security policies, and encrypt traffic between servers, clients, and cloud services.

Implementation of secure network protocols and practices helps organizations protect their data from threats such as man-in-the-middle attacks, traffic analysis, and application-level exploits. With Windows Server 2019 Standard, organizations gain a reliable and proven platform for building secure and scalable network services.

Resilience and High Availability

Windows Server 2019 Standard includes components to ensure resilience and high availability of critical services:

  • Failover Clustering: Enables the creation of clusters of multiple servers for automatic service restarts in case of failure. Windows Server 2019 Standard supports clustering up to two nodes.
  • VLANs and Network Load Balancing: Segment traffic and distribute load among multiple servers to enhance performance and availability.
  • File Server Services and iSCSI: Support Continuous Availability to minimize interruptions during hardware failures or maintenance.

By leveraging these built-in components and features, organizations can build reliable and resilient infrastructures, ensuring the high availability of critical services and data. Windows Server 2019 Standard provides a comprehensive set of tools for ensuring resilience, load balancing, monitoring, and automation, enabling IT teams to effectively manage their environments and meet stringent service level requirements.


Windows Server 2019 Standard provides a reliable foundation for building a secure and resilient IT infrastructure. Built-in features for protection against malicious code, strengthening of credential security, secure network protocols, and high availability capabilities enable organizations to combat modern cyber threats and maintain business process continuity.

While some additional security and scalability features are available only in the Datacenter edition, Windows Server 2019 Standard offers a comprehensive toolkit to meet the needs of most small and medium-sized enterprises. With regular security updates and integration with Microsoft’s cloud services, organizations can be confident that their Windows Server infrastructure is protected and ready for future challenges.

Of course, simply implementing advanced security technologies is not enough for effective protection of IT infrastructure. It is also essential to adhere to proven practices such as regular software updates, network segmentation, access rights management, user training, and activity monitoring. Only by combining reliable technologies with sound management processes can organizations create a truly resilient and secure IT environment.
