Privileged Access

Follow just enough administration (least privilege principle)

Customer

Azure role-based access control (Azure RBAC) allows you to manage Azure resource access through role assignments. You can assign these roles to users, group service principals, and managed identities. There are pre-defined built-in roles for certain resources, and these roles can be inventoried or queried through tools such as Azure CLI, Azure PowerShell, and the Azure portal. The privileges you assign to resources through Azure RBAC should always be limited to what's required by the roles. Limited privileges complement the just in time (JIT) approach of Azure AD Privileged Identity Management (PIM), and those privileges should be reviewed periodically. Use built-in roles to allocate permission and only create custom role when required.

Privileged Access

Follow just enough administration (least privilege) principle

Shared

**Security Principle:** Follow the just enough administration (least privilege) principle to manage permissions at fine-grained level. Use features such as role-based access control (RBAC) to manage resource access through role assignments. **Azure Guidance:** Use Azure role-based access control (Azure RBAC) to manage Azure resource access through role assignments. Through RBAC, you can assign roles to users, group service principals, and managed identities. There are pre-defined built-in roles for certain resources, and these roles can be inventoried or queried through tools such as Azure CLI, Azure PowerShell, and the Azure portal. The privileges you assign to resources through Azure RBAC should always be limited to what's required by the roles. Limited privileges will complement the just-in-time (JIT) approach of Azure AD Privileged Identity Management (PIM), and those privileges should be reviewed periodically. If required, you can also use PIM to define the time-length (time-bound-assignment) condition in role assignment where a user can activate or use the role only within start and end dates. Note: Use Azure built-in roles to allocate permissions and only create custom roles when required. **Implementation and additional context:** What is Azure role-based access control (Azure RBAC): https://docs.microsoft.com/azure/role-based-access-control/overview How to configure RBAC in Azure: https://docs.microsoft.com/azure/role-based-access-control/role-assignments-portal How to use Azure AD identity and access reviews: https://docs.microsoft.com/azure/active-directory/governance/access-reviews-overview Azure AD Privileged Identity Management - Time-bound assignment: https://docs.microsoft.com/azure/active-directory/privileged-identity-management/pim-configure#what-does-it-do

Access Control

Prevent non-privileged users from executing privileged functions and capture the execution of such functions in audit logs.

Shared

Microsoft and the customer share responsibilities for implementing this requirement.

Privileged functions include establishing system accounts, performing system integrity checks, conducting patching operations, or administering cryptographic key management activities. Nonprivileged users are individuals that do not possess appropriate authorizations. Circumventing intrusion detection and prevention mechanisms or malicious code protection mechanisms are examples of privileged functions that require protection from non-privileged users. Note that this requirement represents a condition to be achieved by the definition of authorized privileges in AC.1.002. Misuse of privileged functions, either intentionally or unintentionally by authorized users, or by unauthorized external entities that have compromised system accounts, is a serious and ongoing concern and can have significant adverse impacts on organizations. Logging the use of privileged functions is one way to detect such misuse, and in doing so, help mitigate the risk from insider threats and the advanced persistent threat.

n/a

The organization: a. Identifies and selects the following types of information system accounts to support organizational missions/business functions: [Assignment: organization-defined information system account types]; b. Assigns account managers for information system accounts; c. Establishes conditions for group and role membership; d. Specifies authorized users of the information system, group and role membership, and access authorizations (i.e., privileges) and other attributes (as required) for each account; e. Requires approvals by [Assignment: organization-defined personnel or roles] for requests to create information system accounts; f. Creates, enables, modifies, disables, and removes information system accounts in accordance with [Assignment: organization-defined procedures or conditions]; g. Monitors the use of, information system accounts; h. Notifies account managers: 1. When accounts are no longer required; 2. When users are terminated or transferred; and 3. When individual information system usage or need-to-know changes; i. Authorizes access to the information system based on: 1. A valid access authorization; 2. Intended system usage; and 3. Other attributes as required by the organization or associated missions/business functions; j. Reviews accounts for compliance with account management requirements [Assignment: organization-defined frequency]; and k. Establishes a process for reissuing shared/group account credentials (if deployed) when individuals are removed from the group. Supplemental Guidance: Information system account types include individual, shared, group, system, guest/anonymous, emergency, developer/manufacturer/vendor, temporary, and service. Some of the account management requirements listed above can be implemented by organizational information systems. The identification of authorized users of the information system and the specification of access privileges reflects the requirements in other security controls in the security plan. Users requiring administrative privileges on information system accounts receive additional scrutiny by appropriate organizational personnel (e.g., system owner, mission/business owner, or chief information security officer) responsible for approving such accounts and privileged access. Organizations may choose to define access privileges or other attributes by account, by type of account, or a combination of both. Other attributes required for authorizing access include, for example, restrictions on time-of-day, day-of-week, and point-of-origin. In defining other account attributes, organizations consider system-related requirements (e.g., scheduled maintenance, system upgrades) and mission/business requirements, (e.g., time zone differences, customer requirements, remote access to support travel requirements). Failure to consider these factors could affect information system availability. Temporary and emergency accounts are accounts intended for short-term use. Organizations establish temporary accounts as a part of normal account activation procedures when there is a need for short-term accounts without the demand for immediacy in account activation. Organizations establish emergency accounts in response to crisis situations and with the need for rapid account activation. Therefore, emergency account activation may bypass normal account authorization processes. Emergency and temporary accounts are not to be confused with infrequently used accounts (e.g., local logon accounts used for special tasks defined by organizations or when network resources are unavailable). Such accounts remain available and are not subject to automatic disabling or removal dates. Conditions for disabling or deactivating accounts include, for example: (i) when shared/group, emergency, or temporary accounts are no longer required; or (ii) when individuals are transferred or terminated. Some types of information system accounts may require specialized training.

Least Privilege

Shared

n/a

The organization employs the principle of least privilege, allowing only authorized accesses for users (or processes acting on behalf of users) which are necessary to accomplish assigned tasks in accordance with organizational missions and business functions. Supplemental Guidance: Organizations employ least privilege for specific duties and information systems. The principle of least privilege is also applied to information system processes, ensuring that the processes operate at privilege levels no higher than necessary to accomplish required organizational missions/business functions. Organizations consider the creation of additional processes, roles, and information system accounts as necessary, to achieve least privilege. Organizations also apply least privilege to the development, implementation, and operation of organizational information systems. Related controls: AC-2, AC-3, AC-5, CM-6, CM-7, PL-2.

Supplemental Guidance: The need for certain assigned user privileges may change over time reflecting changes in organizational missions/business function, environments of operation, technologies, or threat. Periodic review of assigned user privileges is necessary to determine if the rationale for assigning such privileges remains valid. If the need cannot be revalidated, organizations take appropriate corrective actions. Related control: CA-7.

Employ the principle of least privilege, including for specific security functions and privileged accounts.

Shared

Microsoft and the customer share responsibilities for implementing this requirement.

Organizations employ the principle of least privilege for specific duties and authorized accesses for users and processes. The principle of least privilege is applied with the goal of authorized privileges no higher than necessary to accomplish required organizational missions or business functions. Organizations consider the creation of additional processes, roles, and system accounts as necessary, to achieve least privilege. Organizations also apply least privilege to the development, implementation, and operation of organizational systems. Security functions include establishing system accounts, setting events to be logged, setting intrusion detection parameters, and configuring access authorizations (i.e., permissions, privileges). Privileged accounts, including super user accounts, are typically described as system administrator for various types of commercial off-the-shelf operating systems. Restricting privileged accounts to specific personnel or roles prevents day-to-day users from having access to privileged information or functions. Organizations may differentiate in the application of this requirement between allowed privileges for local accounts and for domain accounts provided organizations retain the ability to control system configurations for key security parameters and as otherwise necessary to sufficiently mitigate risk.
