Microsoft  70-744 Prep: Windows Server 2016 Security Full Guidance

Securing Windows Server 2016 is a critical responsibility for any IT professional preparing for Exam Ref 70-744. The foundation of server security begins with implementing comprehensive server hardening solutions that minimize vulnerabilities and protect sensitive data from both internal and external threats. Server hardening involves systematically applying a series of configurations, policies, and practices that reduce the attack surface of the system while maintaining the server’s operational functionality. The goal is to ensure that Windows Server 2016 environments remain resilient against unauthorized access, malware, and other security incidents.

Managing User Accounts and Groups

A central component of server hardening is managing and configuring user accounts and groups effectively. By enforcing strict account policies, administrators can limit the potential for unauthorized access. This involves implementing password complexity requirements, enforcing account lockout policies, and ensuring that privileged accounts are used only for tasks requiring elevated permissions. Administrators must also audit user account activity to identify anomalous behavior that could indicate compromise. Configuring security groups and delegating permissions carefully ensures that users have only the access necessary to perform their job functions, minimizing potential security risks.

Securing the Operating System

Another key aspect of server hardening is securing the underlying operating system. Windows Server 2016 provides numerous tools and features to facilitate this process. Applying security updates and patches promptly is essential, as these updates address known vulnerabilities that attackers could exploit. Administrators should also configure automatic update settings and utilize centralized update management through tools such as Windows Server Update Services. Disabling unnecessary services and features reduces the number of potential entry points for attackers. Server roles and features should be carefully reviewed, and any components not required for the server’s intended function should be removed or disabled.

File System and Storage Security

File system and storage security play an essential role in hardening a server. Implementing NTFS permissions appropriately ensures that files and folders are accessible only to authorized users. Administrators should regularly audit access permissions to prevent privilege creep, where users accumulate more permissions than necessary over time. Encrypting sensitive data using technologies such as BitLocker adds a layer of protection, ensuring that data remains secure even if physical drives are compromised. Additionally, enabling auditing on critical files and folders allows organizations to monitor and respond to unauthorized access attempts effectively.

Network Security and Firewalls

Network security is deeply intertwined with server hardening. Configuring firewalls, network segmentation, and secure communication protocols are fundamental practices. Windows Server 2016 includes Windows Defender Firewall, which administrators can configure to control inbound and outbound traffic based on rules tailored to the organization’s security policies. Implementing IPsec and Transport Layer Security (TLS) ensures that network communications are encrypted and protected from interception or tampering. Network Access Control (NAC) can also be used to enforce security compliance on devices attempting to connect to the server environment, reducing the likelihood of malware propagation.

Auditing and Monitoring

Server hardening extends to auditing and monitoring as well. Enabling and configuring Windows Event Logging allows administrators to track system activity, detect anomalies, and investigate potential security incidents. Audit policies should cover critical events, including logon attempts, account management, policy changes, and file access. Centralizing event logs and integrating with a Security Information and Event Management (SIEM) system can enhance visibility and accelerate response times. Monitoring resource utilization and system performance is also important, as unusual patterns may indicate compromise or misconfiguration.

Group Policy and Security Baselines

Group Policy Objects (GPOs) are powerful tools for enforcing security configurations consistently across multiple servers in a Windows Server 2016 environment. Administrators can define password policies, account lockout settings, software restriction policies, and security options through GPOs. Applying these policies reduces the risk of misconfiguration and ensures that security standards are uniformly enforced. Regularly reviewing and updating GPOs is essential to adapt to evolving security requirements and threat landscapes. Security baselines provided by Microsoft serve as excellent starting points for creating hardened configurations tailored to organizational needs.

Securing Remote Administration

Securing remote administration channels is also a critical element of server hardening. Remote Desktop Services, PowerShell remoting, and other remote management interfaces must be configured securely. Using strong authentication methods, such as multi-factor authentication, ensures that only authorized administrators can access the server remotely. Network Level Authentication (NLA) for Remote Desktop protects against unauthorized access by requiring authentication before establishing a session. Administrators should also consider limiting remote access to specific IP addresses or VPN endpoints to reduce exposure to external threats.

Antivirus and Malware Protection

Antivirus and antimalware solutions complement server hardening efforts by actively defending against malicious software. Windows Defender Antivirus, built into Windows Server 2016, provides real-time protection against a wide range of threats. Administrators should ensure that virus definitions are updated regularly and configure scheduled scans to maintain system integrity. Additional security measures, such as application whitelisting through AppLocker, prevent unauthorized or potentially harmful applications from executing on the server, further reducing the risk of compromise.

Auditing, Alerting, and Response

Implementing auditing, monitoring, and alerting policies in conjunction with server hardening practices provides an end-to-end security approach. Administrators should establish alert thresholds for critical events, such as repeated failed login attempts or changes to privileged accounts. Automated response mechanisms can help contain potential threats quickly, minimizing the impact of security incidents. Integrating these measures with organizational incident response procedures ensures that security breaches are handled systematically and efficiently.

Patch Management and Compliance

Patch management, configuration management, and compliance monitoring form another layer of server hardening strategy. Administrators should adopt tools and processes that streamline the deployment of updates and ensure that all servers adhere to organizational security policies. Configuration drift, where servers diverge from established baselines over time, can create vulnerabilities. Regular assessments and automated remediation help maintain consistency across the environment. Leveraging compliance frameworks and guidelines ensures that security measures align with industry standards and regulatory requirements.

Threat Modeling and Risk Assessment

Server hardening also involves preparing for potential attacks through proactive threat modeling and risk assessment. Identifying critical assets, understanding potential attack vectors, and assessing the likelihood and impact of various threats enables administrators to prioritize security efforts effectively. Security configurations should be tailored to mitigate the most significant risks, balancing protection with operational efficiency. Periodic reassessment ensures that hardening measures remain relevant as threats evolve and organizational requirements change.

Securing Administrative Accounts

The security of administrative accounts is particularly important in a hardened server environment. Administrators should implement privileged access management practices, separating administrative accounts from regular user accounts and limiting the number of individuals with elevated privileges. Using just-in-time (JIT) and just-enough-administration (JEA) principles reduces the risk of privilege abuse. Enforcing strong authentication, auditing administrative activities, and rotating credentials regularly further strengthens server security. Protecting administrative accounts is fundamental to preventing attacks that could compromise the entire Windows Server 2016 infrastructure.

Securing Services and Applications

Securing services and applications running on the server requires careful attention to configuration, patching, and monitoring. Web servers, database services, and other critical applications must be configured according to security best practices. Applying the principle of least privilege ensures that services operate with only the permissions necessary for their functionality. Administrators should review service accounts regularly, change default credentials, and monitor for unexpected behavior. Properly secured services reduce the attack surface and limit the potential impact of a security breach.

Security Templates and Baselines

Implementing security templates and baselines simplifies the hardening process. Windows Server 2016 provides built-in security templates that administrators can customize for specific roles and environments. These templates include predefined settings for user rights, security options, audit policies, and registry configurations. Applying templates consistently ensures that servers adhere to established security standards. Baselines can also serve as benchmarks for compliance auditing, making it easier to identify deviations and remediate vulnerabilities proactively.

Virtualization is a core component of modern IT infrastructure, and securing a virtualization environment is a critical skill for administrators preparing for Exam Ref 70-744. Windows Server 2016 includes Hyper-V as its primary virtualization platform, providing organizations with the ability to run multiple virtual machines (VMs) on a single physical host. While virtualization offers tremendous operational benefits, it also introduces unique security challenges. Ensuring the integrity, availability, and confidentiality of virtual machines and the underlying host requires a combination of platform hardening, access control, network security, and continuous monitoring.

Understanding Hyper-V Architecture

The foundation of securing a virtualization infrastructure lies in understanding Hyper-V architecture. Hyper-V uses a parent-child partition model, where the parent partition hosts the Windows Server 2016 management operating system and is responsible for managing child partitions, which contain the virtual machines. Each child partition operates independently but relies on the parent partition for device access and resource management. Proper security measures must be implemented in both the parent and child partitions to prevent unauthorized access and reduce the risk of lateral movement between virtual machines.

Hyper-V also provides virtual switches for networking between VMs and the physical network. These virtual switches can be configured in different modes, including external, internal, and private, each with distinct security implications. Administrators must carefully configure virtual switches to enforce network isolation where required and prevent unauthorized access between virtual machines or to the physical network. Understanding how virtual switches interact with VLANs, port ACLs, and security policies is essential for maintaining a secure virtualization environment.

Hardening the Hyper-V Host

Securing the Hyper-V host is the first step in virtualization hardening. The host operating system should be treated like any critical server and hardened using best practices, including installing security updates promptly, disabling unnecessary services, and configuring Windows Defender Antivirus or equivalent protection. Administrators should limit administrative access to the Hyper-V host using strong authentication and role-based access controls. Multi-factor authentication and Just Enough Administration (JEA) principles can further protect the host from unauthorized changes.

Hyper-V-specific security features, such as secure boot for virtual machines and shielded VMs, provide additional protection for virtual environments. Secure boot ensures that virtual machines start only with trusted operating systems and drivers, preventing the execution of malicious code at startup. Shielded VMs, combined with virtual Trusted Platform Module (TPM) support, encrypt virtual machine disks and state, protecting sensitive data from unauthorized access even if the host is compromised. Enabling these features is a best practice for environments that handle highly sensitive information.

Access Control and Role Management

Effective access control is critical in virtualized environments. Administrators should use Role-Based Access Control (RBAC) to delegate permissions carefully, ensuring that users and groups have only the privileges necessary to perform their tasks. Hyper-V includes built-in roles such as Hyper-V Administrators, Hyper-V Hosts, and Virtual Machine Administrators, each with distinct capabilities. Assigning users to these roles based on the principle of least privilege minimizes the potential for accidental or malicious actions that could compromise the virtualization infrastructure.

Securing administrative credentials is equally important. Privileged accounts used for managing Hyper-V should have strong, unique passwords and be monitored for anomalous behavior. Enforcing account expiration policies and implementing just-in-time administrative access reduces the risk of credential misuse. Additionally, administrative sessions should be conducted over secure channels, such as Remote Desktop with Network Level Authentication (NLA) or encrypted PowerShell remoting, to prevent interception by unauthorized actors.

Securing Virtual Machine Networks

Virtual networks in Hyper-V must be configured to prevent unauthorized access between virtual machines and the physical network. Administrators should segment networks based on workload sensitivity and apply virtual LANs (VLANs) to isolate traffic. Internal and private virtual switches can be used to restrict network connectivity between VMs and control access to sensitive resources. Implementing virtual network security policies, including firewall rules and port ACLs, further reduces the risk of attacks originating from compromised virtual machines.

Integration with host-based firewalls and network monitoring solutions enhances visibility and control over VM traffic. Administrators should establish logging and alerting for suspicious activity on virtual networks, including unusual communication patterns between virtual machines or external endpoints. Enforcing encryption for network traffic within and between virtual machines provides an additional layer of protection against eavesdropping and tampering.

Virtual Machine Security Best Practices

Each virtual machine requires its own security controls. VMs should be deployed with only the necessary operating system features and services enabled, reducing the potential attack surface. Applying security updates promptly, configuring antivirus and antimalware solutions, and auditing critical system events are essential for maintaining VM integrity. Administrators should also enforce strong authentication and access control within each VM, including separate administrative accounts for virtual machine operations.

Snapshots and checkpoints provide convenience for testing and recovery but introduce security considerations. Administrators should manage checkpoints carefully, ensuring that sensitive data is not exposed through improperly stored snapshots. Removing unnecessary checkpoints and monitoring their creation helps reduce risk while maintaining the ability to recover from system failures.

Protecting Virtual Machine Storage

Storage security is an integral part of virtualization hardening. Hyper-V supports multiple storage options, including VHD and VHDX virtual disks, SMB file shares, and Storage Spaces Direct. Administrators should ensure that virtual disks are stored on encrypted volumes and implement access controls to prevent unauthorized access to VM storage locations. Storage encryption, combined with proper permissions, ensures that sensitive data remains protected even if physical storage devices are compromised.

Backups of virtual machines must be secured as well. Administrators should encrypt backup data and restrict access to backup repositories. Regularly testing backup and restore procedures ensures that recovery is possible without exposing sensitive information. Implementing a consistent backup schedule, combined with offsite or cloud storage, enhances resilience against ransomware and other destructive attacks targeting virtual machines.

Monitoring and Auditing Virtual Environments

Continuous monitoring and auditing are critical for maintaining a secure virtualization infrastructure. Administrators should enable event logging for both the Hyper-V host and the virtual machines. Key events include changes to virtual machine configuration, checkpoint creation, and network modifications. Integrating these logs into a Security Information and Event Management (SIEM) system enhances visibility and allows for rapid detection of anomalies or suspicious activity.

Monitoring resource utilization and performance metrics also plays a security role. Unusual spikes in CPU, memory, or network usage may indicate compromise or unauthorized activity within virtual machines. Establishing baseline metrics and alert thresholds allows administrators to respond promptly to potential threats, minimizing the impact of security incidents.

Integration with Windows Server Security Features

Securing virtualization infrastructure is not limited to Hyper-V itself; integration with broader Windows Server 2016 security features is essential. Administrators should apply GPO-based security policies, enforce encryption using BitLocker, and leverage Windows Defender Antivirus for host and VM protection.

Manage Privileged Identities

Managing privileged identities is a cornerstone of security in Windows Server 2016 and a critical focus area for administrators preparing for Exam Ref 70-744. Privileged accounts, including administrative and service accounts, possess elevated permissions that allow them to configure systems, manage users, and access sensitive data. While necessary for operations, these accounts also represent high-value targets for attackers. Compromise of privileged identities can lead to severe breaches, data loss, and disruption of organizational services. Implementing robust strategies for managing, monitoring, and protecting privileged accounts is essential for a secure environment.

Understanding Privileged Accounts

Privileged accounts encompass a variety of roles, including domain administrators, local administrators, service accounts, and users with delegated permissions. Each type carries distinct risks and responsibilities. Domain administrators control all aspects of Active Directory, making their accounts especially sensitive. Service accounts often have elevated privileges to run applications or services, but improper management can allow attackers to exploit them for lateral movement. Understanding the function, scope, and risk level of each privileged account is the first step in implementing a comprehensive security strategy.

Implementing Just Enough Administration

Just Enough Administration (JEA) is a feature in Windows Server 2016 that allows administrators to delegate only the permissions necessary to perform specific tasks. By limiting the scope of administrative privileges, JEA reduces the attack surface associated with privileged accounts. Administrators can create role capabilities that define the actions a user can perform and session configurations that control access to the server environment. Using JEA ensures that privileged accounts are not over-provisioned, which is a common source of security vulnerabilities.

Just-in-Time Administration

Just-in-Time (JIT) administration complements JEA by providing temporary elevated privileges to users only when needed. Instead of maintaining permanent administrative access, JIT allows users to request privileges for a limited period, after which the access automatically expires. This approach minimizes the window of opportunity for attackers to exploit compromised accounts. JIT administration is particularly effective in environments with high turnover or frequent administrative tasks, ensuring that privileged access is tightly controlled and auditable.

Securing Administrative Credentials

Protecting the credentials of privileged accounts is critical. Strong, complex passwords combined with multi-factor authentication provide a first layer of defense. Windows Server 2016 supports integration with Active Directory Federation Services (AD FS) and other identity providers to enforce secure authentication. Administrators should enforce regular credential rotation, prevent reuse of passwords, and monitor for credential leaks or unauthorized access attempts. Additionally, sensitive accounts should be isolated from routine user environments to reduce exposure to phishing and malware attacks.

Privileged Access Workstations

Privileged Access Workstations (PAWs) are dedicated systems configured specifically for administrative tasks. By isolating administrative activities from general-purpose workstations, organizations reduce the risk of credential theft or malware infection affecting privileged accounts. PAWs should be hardened with minimal software installations, strict access controls, and up-to-date security patches. Use of PAWs ensures that privileged tasks are performed in a controlled, secure environment aligned with Exam Ref 70-744 security principles.

Multi-factor authentication (MFA) strengthens the protection of privileged identities by requiring additional verification beyond passwords. MFA reduces the risk of account compromise from credential theft or phishing attacks. Windows Server 2016 supports integration with Azure MFA, smart cards, and other authentication mechanisms. By requiring MFA for administrative logins and sensitive operations, organizations significantly improve the security of privileged accounts.

Segregation of Duties

Segregation of duties (SoD) is a fundamental principle for managing privileged identities. Administrators should separate responsibilities to prevent conflicts of interest and reduce the risk of insider threats. For example, one group may manage user accounts, while another oversees system configuration or access monitoring. Implementing SoD ensures that no single individual has unchecked control over critical systems, mitigating potential abuse of privileged access.

Continuous Improvement and Risk Assessment

Privileged identity management is not a one-time effort. Continuous assessment of account usage, access patterns, and potential vulnerabilities is essential. Administrators should review access policies regularly, adjust permissions as roles change, and implement new security features offered by Windows Server 2016. Proactive risk assessment, combined with auditing, monitoring, and JIT/JEA practices, ensures that privileged identities remain secure and aligned with organizational policies and Exam Ref 70-744 requirements.

Overview of Windows Server 2016 Security

Securing Windows Server 2016 is a multifaceted task that requires attention to detail across multiple domains of IT administration. Organizations rely on Windows Server 2016 for hosting critical applications, managing user identities, storing sensitive data, and supporting essential business operations. The security of this infrastructure is not merely a technical requirement but a business imperative. Administrators must integrate technical safeguards, policy enforcement, and proactive monitoring to maintain integrity, availability, and confidentiality. Exam Ref 70-744 emphasizes these competencies because the role of a Windows Server administrator involves not only managing day-to-day operations but also anticipating and mitigating potential security risks that could compromise organizational objectives.

Security begins with understanding the threat landscape. Threats to Windows Server 2016 environments are dynamic, including malware, ransomware, insider threats, unauthorized access attempts, and attacks targeting specific vulnerabilities. Administrators must analyze the likelihood and potential impact of each threat and deploy defenses that address both technical and operational risks. Effective security combines preventative, detective, and corrective controls. Preventative measures include hardening, network segmentation, and access control. Detective controls involve monitoring, auditing, and threat detection. Corrective controls encompass incident response, recovery procedures, and policy adjustments following an event.

Importance of Server Hardening

Server hardening is the first line of defense in securing Windows Server 2016. It involves reducing the system’s attack surface by disabling unnecessary services, closing unused ports, and applying security patches. File system security is another critical aspect of hardening. Administrators must assign appropriate NTFS permissions to ensure that users can only access the files and folders required for their roles. Encrypting sensitive data using BitLocker or Encrypting File System (EFS) prevents unauthorized access in case of physical theft or breach.

Security baselines, such as those recommended by Microsoft, provide a reference for best practices and ensure consistent configuration across multiple servers. Administrators should implement Group Policy Objects (GPOs) to enforce account lockout policies, password complexity requirements, and auditing rules across the domain. Windows Defender Antivirus, built into Windows Server 2016, offers real-time protection against malware and integrates with centralized management tools to enforce organizational security policies.

Hardening also extends to logging and monitoring. By enabling advanced audit policies, administrators can track modifications to system configurations, monitor user activity, and detect unauthorized access attempts. Logging and auditing create visibility into system behavior, which is crucial for both threat detection and regulatory compliance. Server hardening establishes the foundation upon which all other security measures are built, reducing the likelihood that attackers can exploit vulnerabilities to compromise the environment.

Securing Virtualization Environments

Virtualization is a core component of Windows Server 2016 infrastructure. Hyper-V allows administrators to run multiple virtual machines on a single physical host, optimizing resource utilization and operational efficiency. However, virtualization also introduces unique security challenges. Compromising a Hyper-V host can lead to complete control over all virtual machines running on that host. Similarly, vulnerabilities within a virtual machine could allow attackers to access other workloads if isolation mechanisms are not implemented correctly.

Administrators must secure both the host and guest operating systems. Shielded virtual machines provide encryption and integrity protection for highly sensitive workloads, ensuring that only authorized hosts and administrators can access the VM. Secure boot prevents the execution of untrusted operating systems or bootloaders, protecting against rootkits and firmware attacks. Virtual networks must be configured to isolate sensitive traffic, restrict broadcast domains, and enforce network policies that prevent lateral movement between VMs. Role-based access control and Just-in-Time (JIT) administration minimize the risk associated with privileged accounts, ensuring that administrative privileges are granted only when necessary and for a limited duration.

Monitoring virtualized environments is also critical. Administrators must track resource usage, network traffic, and system logs for both hosts and virtual machines. Unusual activity, such as unexpected CPU spikes, network connections, or configuration changes, may indicate a security incident. Combining virtualization-specific protections with broader Windows Server 2016 security measures ensures a resilient environment aligned with the standards measured in Exam Ref 70-744.

Network Security and Monitoring

The security of network infrastructure underpins the overall protection of Windows Server 2016 environments. Network security controls prevent unauthorized access, maintain data confidentiality, and ensure operational continuity. Administrators must implement firewalls, secure DNS and DHCP services, and apply network segmentation to isolate sensitive resources. Network segmentation reduces the impact of potential breaches by limiting lateral movement and restricting access to critical systems.

Remote access introduces additional complexity. VPNs, DirectAccess, and Always On VPN provide secure connectivity for remote users, but access must be tightly controlled. Multi-factor authentication, endpoint compliance checks, and conditional access policies reduce the risk of compromised devices accessing the network. Administrators should monitor traffic patterns and configure alerts for suspicious activity, such as repeated failed authentication attempts, anomalous data flows, or access from unauthorized locations.

Monitoring and logging are essential components of network security. Event logs capture detailed information about connections, firewall activity, and access attempts. Integrating logs with a Security Information and Event Management (SIEM) solution allows administrators to correlate events, detect anomalies, and respond to incidents in real time. Continuous review and optimization of network policies, along with threat intelligence integration, ensures that network defenses remain effective against emerging attack vectors.

Managing Privileged Identities

Privileged identities represent one of the highest security risks in Windows Server 2016 environments. These accounts, including domain administrators, local administrators, and service accounts, have elevated permissions that, if compromised, can lead to catastrophic breaches. Administrators must implement strategies to secure privileged accounts while maintaining operational efficiency.

Just Enough Administration (JEA) and Just-in-Time (JIT) access are critical for minimizing privilege exposure. JEA allows administrators to delegate only the specific permissions required for tasks, while JIT ensures temporary access is granted for defined durations. Privileged Access Workstations (PAWs) provide a secure environment for administrative tasks, reducing the risk of credential theft from general-purpose endpoints. Multi-factor authentication, strong password policies, and secure credential storage further protect privileged accounts from compromise.

Monitoring and auditing privileged account activity is essential for early detection of misuse or attacks. Administrators should track logons, configuration changes, and access to sensitive resources, integrating alerts into SIEM systems for centralized analysis. Service accounts require additional attention, including minimum privilege assignment, managed service accounts, and periodic review to remove dormant accounts. Effective management of privileged identities aligns with Exam Ref 70-744 requirements and is crucial for maintaining a secure Windows Server 2016 environment.

Threat Detection and Response

Threat detection is a proactive and ongoing requirement for securing Windows Server 2016. Windows Defender Advanced Threat Protection (ATP), Credential Guard, and Device Guard provide sophisticated monitoring, behavioral analysis, and detection capabilities. These tools can identify unusual process behavior, suspicious network activity, and potential compromise of privileged accounts.

Auditing, logging, and SIEM integration allow administrators to correlate events across multiple servers and endpoints. Alerts and automated response mechanisms help contain threats before they escalate. Behavioral analytics, anomaly detection, and threat intelligence integration provide additional context, enabling more accurate identification of incidents. Regular updates and proactive monitoring ensure that threat detection mechanisms remain effective against evolving threats. Combining detection with incident response workflows and automated remediation supports resilience and operational continuity.

Workload-Specific Security Measures

Workload-specific security ensures that each server, application, and service is protected according to its unique function and risk profile. Web servers, database servers, file servers, and application servers require tailored controls, including encryption, access restrictions, auditing, and monitoring. Virtual machines and Remote Desktop Services demand secure boot, isolation, and multi-factor authentication. Patch management, firewall configuration, and monitoring of workload activity ensure that sensitive workloads are protected against vulnerabilities and attacks.

Administrators must continuously evaluate workload security, adjusting controls as applications, user roles, and threat landscapes evolve. Aligning these measures with organizational policies, regulatory compliance, and Exam Ref 70-744 objectives ensures that all workloads operate securely and efficiently.

Layered Security Approach

A layered or defense-in-depth strategy is fundamental to Windows Server 2016 security. No single measure can fully protect an environment; instead, multiple overlapping controls provide resilience. Server hardening, virtualization protection, network security, privileged identity management, threat detection, and workload-specific safeguards collectively reduce risk. Layered security ensures that if one control is bypassed, others continue to protect the environment, maintaining confidentiality, integrity, and availability.

Continuous Improvement and Risk Assessment

Security is a continuous journey rather than a one-time implementation. Administrators must regularly assess risks, review configurations, and update policies to address new threats. Proactive risk assessment allows organizations to prioritize remediation efforts, focusing resources on the most critical assets. Continuous improvement, including monitoring, auditing, and integration of automated tools, ensures that the Windows Server 2016 environment remains resilient and compliant.

Alignment with Exam Ref 70-744
