Azure IAM

Kwa maelezo zaidi angalia:

Az - Entra ID (AzureAD) & Azure IAM

Microsoft.Authorization/roleAssignments/write

Ruhusa hii inaruhusu kupewa majukumu kwa wahusika juu ya upeo maalum, ikimruhusu mshambuliaji kupandisha hadhi kwa kujipatia jukumu lenye mamlaka zaidi:

# Example
az role assignment create --role Owner --assignee "24efe8cf-c59e-45c2-a5c7-c7e552a07170" --scope "/subscriptions/9291ff6e-6afb-430e-82a4-6f04b2d05c7f/resourceGroups/Resource_Group_1/providers/Microsoft.KeyVault/vaults/testing-1231234"

Microsoft.Authorization/roleDefinitions/Write

Ruhusa hii inaruhusu kubadilisha ruhusa zilizotolewa na jukumu, ikimruhusu mshambuliaji kupandisha hadhi kwa kutoa ruhusa zaidi kwa jukumu aliloteua.

Unda faili role.json yenye maudhui yafuatayo:

{
"Name": "<name of the role>",
"IsCustom": true,
"Description": "Custom role with elevated privileges",
"Actions": [
"*"
],
"NotActions": [],
"DataActions": [
"*"
],
"NotDataActions": [],
"AssignableScopes": [
"/subscriptions/<subscription-id>"
]
}

Kisha sasisha ruhusa za jukumu kwa ufafanuzi wa awali ukitumia:

az role definition update --role-definition role.json

Microsoft.Authorization/elevateAccess/action

Hii ruhusa inaruhusu kuinua mamlaka na kuwa na uwezo wa kutoa ruhusa kwa mtu yeyote kwa rasilimali za Azure. Imepangwa kutolewa kwa Wasimamizi wa Kimataifa wa Entra ID ili waweze pia kusimamia ruhusa juu ya rasilimali za Azure.

Nadhani mtumiaji anahitaji kuwa Msimamizi wa Kimataifa katika Entra ID ili wito wa kuinua ufanye kazi.

# Call elevate
az rest --method POST --uri "https://management.azure.com/providers/Microsoft.Authorization/elevateAccess?api-version=2016-07-01"

# Grant a user the Owner role
az role assignment create --assignee "<obeject-id>" --role "Owner" --scope "/"

Microsoft.ManagedIdentity/userAssignedIdentities/federatedIdentityCredentials/write

Ruhusa hii inaruhusu kuongeza akreditivu za Shirikisho kwa utambulisho unaosimamiwa. Mfano: kutoa ufikiaji kwa Github Actions katika repo kwa utambulisho unaosimamiwa. Kisha, inaruhusu kufikia utambulisho wowote wa usimamizi ulioelezwa na mtumiaji.

Mfano wa amri ya kutoa ufikiaji kwa repo katika Github kwa utambulisho unaosimamiwa:

# Generic example:
az rest --method PUT \
--uri "https://management.azure.com//subscriptions/<subscription-id>/resourceGroups/<res-group>/providers/Microsoft.ManagedIdentity/userAssignedIdentities/<managed-identity-name>/federatedIdentityCredentials/<name-new-federated-creds>?api-version=2023-01-31" \
--headers "Content-Type=application/json" \
--body '{"properties":{"issuer":"https://token.actions.githubusercontent.com","subject":"repo:<org-name>/<repo-name>:ref:refs/heads/<branch-name>","audiences":["api://AzureADTokenExchange"]}}'

# Example with specific data:
az rest --method PUT \
--uri "https://management.azure.com//subscriptions/92913047-10a6-2376-82a4-6f04b2d03798/resourceGroups/Resource_Group_1/providers/Microsoft.ManagedIdentity/userAssignedIdentities/funcGithub-id-913c/federatedIdentityCredentials/CustomGH2?api-version=2023-01-31" \
--headers "Content-Type=application/json" \
--body '{"properties":{"issuer":"https://token.actions.githubusercontent.com","subject":"repo:carlospolop/azure_func4:ref:refs/heads/main","audiences":["api://AzureADTokenExchange"]}}'
