How the controls work.
In this control the solution tries to validate multiple items as follow.
-
The solution will verify the existence of the two Break Glass accounts that you have entered in the config.json during the setup process.Once the solution detects both accounts the check mark status will be changed from (❌) to (✔️).
-
Break Glass accounts Procedure
If you have completed the break glass accounts procedure, make sure to upload an empty Text file with the name "BreakGlassAccountProcedure.txt" to the container name "guardrailsstorage" in the storage account created by the setup. this file tell the solution that you have completed this task. please do not upload the break glass account procedure it self, once the solution detects the file, the check mark status will be changed from (❌) to (✔️).
-
Break Glass Accounts Owners contacts information
Break Glass Account must be owned by in the organization, the owner is the manager of the accounts , the solution will verify if the manager information for both Break Glass Accounts is populated, once the solution detects the manager information for both accounts, the check mark status will be changed from (❌) to (✔️).
-
Responsibility of Break Glass accounts
After you confirm that the person(s) responsible of the Break Glass accounts is not technical and and has a director level or above make sure to upload an empty Text file with the name "ConfirmBreakGlassAccountResponsibleIsNotTechnical.txt" to the container name "guardrailsstorage" in the storage account created by the setup. this file tells the solution that you have completed this task. Once the solution detects the file, the check mark status will be changed from (❌) to (✔️).
-
AD License Type
The module will look for a P2 equivalent licensing, Once the solution find any of the following "String Id", the check mark status will be changed from (❌) to (✔️).
- Product name: AZURE ACTIVE DIRECTORY PREMIUM P2, String ID: AAD_PREMIUM_P2
- Product name: ENTERPRISE MOBILITY + SECURITY E5, String ID: EMSPREMIUM
- Product name: Microsoft 365 E5, String ID: SPE_E5
-
Break Glass Accounts Restricted Access
The module checks if the multi-factor authentication (MFA) is enable on the break glass account, if MFA is not enabled the check mark status will be changed from (❌) to (✔️).
-
Break Glass Accounts must be created in the tenant Azure Active Directory
The solution checks if both break glass accounts are member of the Azure Active Directory, and not guest account or from another directory. if the solution finds both break glass accounts are member of the Azure Active Directory it will change the check mark status from (❌) to (✔️).
- Check Deleted and Disabled Users
- Check Deprecated Accounts
- Check External User Accounts
This Module module verifies the following items:
- The existance of at least one Conditional Access Named Location that only contains Canada. If no Location is defined or no locations have just Canada in it, the control will be considered non-Compliant.
- If the above is Compliant, the solution with check if there is at least one conditional access policy that uses any of the Canada only named locations determined before. If no policies with this criteria are found, the control will be considered non-compliant.
- The existence of a file named 'PrivilegedAccountManagementPlan.txt' (case-sensitive) in the Guardrails Solution Accelerator storage account, providing attestation that the organization has the required privileged account management plan documented.
This modules will look for the existance of an account in the following format:
"SSC-CBS-Reporting@" + DepartmentNumber + "gc.onmicrosoft.com"
The Department number is provided as a parameter in the config.json during deployment and can be updated in the Automation Account variables.
If no account is found in Azure AD as per above, the control will be considered non-compliant.
This Module will verify the existence of an assignment of the 'Allowed Locations' policy in the multiple subscriptions and management groups. The standard guid for this Policy is:
e56962a6-4747-49cd-b67b-bf8b01975c4c.
If the built-in policy is used for this purpose, no configuration is required. If a custom policy is being used for this purpose (define allowed locations), this guid can be specified in the config.json file during deployment of in the Automation Account variables.
This Module will detect the PBMM Initiative. The detection will happen at the Root Tenant management group and down, looking for all subscriptions and management groups. Any subscription of MG without the applied initial will be marked as non compliant.
The standard guid for this Policy is:
4c4a5f27-de81-430b-b4e5-9cbd50595a87.
If the built-in policy is used for this purpose, no configuration is required. If a custom policy is being used for this purpose (PBMM initiative), this guid can be specified in the config.json file during deployment of in the Automation Account variables.
This module will detect the PBMM and look for specific policies not to be exempted. The compliance will fail right away if the PBMM policy is not applied. If applied, the following policies will be checked for exemptions:
- "TransparentDataEncryptionOnSqlDatabasesShouldBeEnabled"
- "DiskEncryptionShouldBeAppliedOnVirtualMachines"
This module will detect the PBMM and look for specific policies not to be exempted. The compliance will fail right away if the PBMM policy is not applied. If applied, the following policies will be checked for exemptions:
- "FunctionAppShouldOnlyBeAccessibleOverHttps"
- "WebApplicationShouldOnlyBeAccessibleOverHttps"
- "ApiAppShouldOnlyBeAccessibleOverHttps"
- "OnlySecureConnectionsToYourRedisCacheShouldBeEnabled"
- "SecureTransferToStorageAccountsShouldBeEnabled"
This module will retrieve the list of subnets in all available VNets (all VNets visible to the managed identity, according to the permissions assigned (Typically, all since permissions are assigned at the Root Management Group level))
For each subnet the following items will be evaluated:
- Existence of an NSG attached to the subnet.
- In the said NSG, there must be a rule, set as the last rule in the custom rules, and configured to deny all traffic.
If any of the above rules is not true, the subnet will be considered non compliant
- Existence of an UDR (Route table) assigned to the subnet
- The UDR must have a default (0.0.0.0/0) route set to a Virtual Appliance.
If any of the above rules is not true, the subnet will be considered not compliant.
Subnets can be excluded from the compliance check in four different ways:
Automatically:
- The following subnets are considered reserved and are automatically excluded: GatewaySubnet,AzureFirewallSubnet,AzureBastionSubnet,AzureFirewallManagementSubnet,RouteServerSubnet This configuration is contained in the 'reservedSubnetList' variable in the Automation Account and can be updated as needed.
The whole VNet:
- If a tag named "GR8-ExcludeVNetFromCompliance" is found in the VNet, all subnets are ignored.
One or more specific subnets:
-
A tag called "GR-ExcludedSubnets" is found, containing a list of subnets separated by commas, each of those subnets will be excluded from the compliance check.
-
A list of subnet names can be provided as a parameter to the module ($ExcludedSubnetsList). All subnets in this list will be excluded from the compliance check, from all VNets.
- If you have created a network diagram and it meets ITSG-33 controls, make sure to upload an empty text file with the name "ConfirmNetworkDiagramExists.txt" to the container name "guardrailsstorage" in the storage account created by the setup. This file tells the solution that you have completed this task. Please do not upload the network diagram itself. Once the solution detects the file, the check mark status will be changed from (❌) to (✔️).
This module will retrieve the list of all VNets (all VNets visible to the managed identity, according to the permissions assigned (Typically, all since permissions are assigned at the Root Management Group level))
For each VNet the following items will be evaluated.
- DDos Protection set to Standard (Enabling DDos standard protection on your Azure environment will have a financial impact on your monthly billing)
If any of the above rules is not true, the VNet will be considered not compliant.
If the Vnet object containts a tag "GR9-ExcludeVNetFromCompliance" the VNet will be excluded from the compliance check.
The solution will verify the existence of the Cyber Defense Services resources in the dedicated Cyber Defense Services subscription in the config.json during the setup process. Once the solution detects these resources the check mark status will be changed from (❌) to (✔️).
