Azure_Security_Benchmark_v3.0 PV-4 Azure_Security_Benchmark_v3.0_PV-4 Azure Security Benchmark PV-4 Posture and Vulnerability Management Audit and enforce secure configurations for compute resources Shared **Security Principle:** Continuously monitor and alert when there is a deviation from the defined configuration baseline in your compute resources. Enforce the desired configuration according to the baseline configuration by denying the non-compliant configuration or deploy a configuration in compute resources. **Azure Guidance:** Use Microsoft Defender for Cloud and Azure Policy guest configuration agent to regularly assess and remediate configuration deviations on your Azure compute resources, including VMs, containers, and others. In addition, you can use Azure Resource Manager templates, custom operating system images, or Azure Automation State Configuration to maintain the security configuration of the operating system. Microsoft VM templates in conjunction with Azure Automation State Configuration can assist in meeting and maintaining security requirements. Note: Azure Marketplace VM images published by Microsoft are managed and maintained by Microsoft. **Implementation and additional context:** How to implement Microsoft Defender for Cloud vulnerability assessment recommendations: https://docs.microsoft.com/azure/security-center/security-center-vulnerability-assessment-recommendations How to create an Azure virtual machine from an ARM template: https://docs.microsoft.com/azure/virtual-machines/windows/ps-template Azure Automation State Configuration overview: https://docs.microsoft.com/azure/automation/automation-dsc-overview Create a Windows virtual machine in the Azure portal: https://docs.microsoft.com/azure/virtual-machines/windows/quick-create-portal Container security in Microsoft Defender for Cloud: https://docs.microsoft.com/azure/security-center/container-security n/a link 10

SOC_2 CC6.8 SOC_2_CC6.8 SOC 2 Type 2 CC6.8 Logical and Physical Access Controls Prevent or detect against unauthorized or malicious software Shared The customer is responsible for implementing this recommendation. Restricts Application and Software Installation — The ability to install applications and software is restricted to authorized individuals. • Detects Unauthorized Changes to Software and Configuration Parameters — Processes are in place to detect changes to software and configuration parameters that may be indicative of unauthorized or malicious software. • Uses a Defined Change Control Process — A management-defined change control process is used for the implementation of software. • Uses Antivirus and Anti-Malware Software — Antivirus and anti-malware software is implemented and maintained to provide for the interception or detection and remediation of malware. • Scans Information Assets from Outside the Entity for Malware and Other Unauthorized Software — Procedures are in place to scan information assets that have been transferred or returned to the entity’s custody for malware and other unauthorized software and to remove any items detected prior to its implementation on the network. 54
SOC_2 CC8.1 SOC_2_CC8.1 SOC 2 Type 2 CC8.1 Change Management Changes to infrastructure, data, and software Shared The customer is responsible for implementing this recommendation. Manages Changes Throughout the System Life Cycle — A process for managing system changes throughout the life cycle of the system and its components (infrastructure, data, software, and procedures) is used to support system availability and processing integrity. • Authorizes Changes — A process is in place to authorize system changes prior to development. • Designs and Develops Changes — A process is in place to design and develop system changes. • Documents Changes — A process is in place to document system changes to support ongoing maintenance of the system and to support system users in performing their responsibilities. • Tracks System Changes — A process is in place to track system changes prior to implementation. • Configures Software — A process is in place to select and implement the configuration parameters used to control the functionality of software. • Tests System Changes — A process is in place to test system changes prior to implementation. • Approves System Changes — A process is in place to approve system changes prior to implementation. • Deploys System Changes — A process is in place to implement system changes. • Identifies and Evaluates System Changes — Objectives affected by system changes are identified and the ability of the modified system to meet the objectives is evaluated throughout the system development life cycle. • Identifies Changes in Infrastructure, Data, Software, and Procedures Required to Remediate Incidents — Changes in infrastructure, data, software, and procedures required to remediate incidents to continue to meet objectives are identified and the change process is initiated upon identification. • Creates Baseline Configuration of IT Technology — A baseline configuration of IT and control systems is created and maintained. • Provides for Changes Necessary in Emergency Situations — A process is in place for authorizing, designing, testing, approving, and implementing changes necessary in emergency situations (that is, changes that need to be implemented in an urgent time frame). Additional points of focus that apply only in an engagement using the trust services criteria for confidentiality: • Protects Confidential Information — The entity protects confidential information during system design, development, testing, implementation, and change processes to meet the entity’s objectives related to confidentiality. Additional points of focus that apply only in an engagement using the trust services criteria for privacy: • Protects Personal Information — The entity protects personal information during system design, development, testing, implementation, and change processes to meet the entity’s objectives related to privacy. 53
