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.

Establish and maintain baseline configurations and inventories of organizational systems (including hardware, software, firmware, and documentation) throughout the respective system development life cycles.
Shared
Microsoft and the customer share responsibilities for implementing this requirement.
Baseline configurations are documented, formally reviewed, and agreed-upon specifications for systems or configuration items within those systems. Baseline configurations serve as a basis for future builds, releases, and changes to systems. Baseline configurations include information about system components (e.g., standard software packages installed on workstations, notebook computers, servers, network components, or mobile devices; current version numbers and update and patch information on operating systems and applications; and configuration settings and parameters), network topology, and the logical placement of those components within the system architecture. Baseline configurations of systems also reflect the current enterprise architecture. Maintaining effective baseline configurations requires creating new baselines as organizational systems change over time. Baseline configuration maintenance includes reviewing and updating the baseline configuration when changes are made based on security risks and deviations from the established baseline configuration
Organizations can implement centralized system component inventories that include components from multiple organizational systems. In such situations, organizations ensure that the resulting inventories include system-specific information required for proper component accountability (e.g., system association, system owner). Information deemed necessary for effective accountability of system components includes hardware inventory specifications, software license information, software version numbers, component owners, and for networked components or devices, machine names and network addresses. Inventory specifications include manufacturer, device type, model, serial number, and physical location.
Harden host and guest OS, hypervisor or infrastructure control plane
according to their respective best practices, and supported by technical controls,
as part of a security baseline.
The organization:
a. Establishes and documents configuration settings for information technology products employed within the information system using [Assignment: organization-defined security configuration checklists] that reflect the most restrictive mode consistent with operational requirements;
b. Implements the configuration settings;
c. Identifies, documents, and approves any deviations from established configuration settings for [Assignment: organization-defined information system components] based on [Assignment: organization-defined operational requirements]; and
d. Monitors and controls changes to the configuration settings in accordance with organizational policies and procedures.
Supplemental Guidance: Configuration settings are the set of parameters that can be changed in hardware, software, or firmware components of the information system that affect the security posture and/or functionality of the system. Information technology products for which security- related configuration settings can be defined include, for example, mainframe computers, servers (e.g., database, electronic mail, authentication, web, proxy, file, domain name), workstations, input/output devices (e.g., scanners, copiers, and printers), network components (e.g., firewalls, routers, gateways, voice and data switches, wireless access points, network appliances, sensors), operating systems, middleware, and applications. Security-related parameters are those parameters impacting the security state of information systems including the parameters required to satisfy other security control requirements. Security-related parameters include, for example: (i) registry settings; (ii) account, file, directory permission settings; and (iii) settings for functions, ports, protocols, services, and remote connections. Organizations establish organization-wide configuration settings and subsequently derive specific settings for information systems. The established settings become part of the systems configuration baseline.
Common secure configurations (also referred to as security configuration checklists, lockdown
and hardening guides, security reference guides, security technical implementation guides) provide recognized, standardized, and established benchmarks that stipulate secure configuration settings for specific information technology platforms/products and instructions for configuring those information system components to meet operational requirements. Common secure configurations can be developed by a variety of organizations including, for example, information technology product developers, manufacturers, vendors, consortia, academia, industry, federal agencies, and other organizations in the public and private sectors. Common secure configurations include the United States Government Configuration Baseline (USGCB) which affects the implementation of CM-6 and other controls such as AC-19 and CM-7. The Security Content Automation Protocol (SCAP) and the defined standards within the protocol (e.g., Common Configuration Enumeration) provide an effective method to uniquely identify, track, and control configuration settings. OMB establishes federal policy on configuration requirements for federal information systems. Related controls: AC-19, CM-2, CM-3, CM-7, SI-4.

Establishing usage restrictions, configuration requirements, and connection requirements for wireless access to the system provides criteria to support access authorization decisions. These restrictions and requirements reduce susceptibility to unauthorized system access through wireless technologies. Wireless networks use authentication protocols that provide credential protection and mutual authentication. Organizations authenticate individuals and devices to protect wireless access to the system. Special attention is given to the variety of devices with potential wireless access to the system, including small form factor mobile devices (e.g., smart phones, smart watches). Wireless networking capabilities that are embedded within system components represent a significant potential vulnerability that can be exploited by adversaries. Disabling wireless capabilities when not needed for essential missions or business functions can help reduce susceptibility to threats by adversaries involving wireless technologies.
