Ensure the Storage Container Storing the Activity Logs is not Publicly Accessible (Manual)


This rule has been changed to manual, see Permanently Manual Policies for CIS Azure 1.5.0 for details.

Profile Applicability

• Level 1


The storage account container containing the activity log export should not be publicly accessible.


Allowing public access to activity log content may aid an adversary in identifying weaknesses in the affected account's use or configuration.


Configuring container Access policy to private will remove access from the container for everyone except owners of the storage account. Access policy needs to be set explicitly in order to allow access to other desired users.

  1. From Azure Home select the Portal Menu
  2. Select Diagnostic Settings in the left column.
  3. In section Storage Account, note the name of the Storage account
  4. Close Diagnostic settings. Close the Monitor - Activity Log blade.
  5. In right column, Click service Storage Accounts to access Storage account blade
  6. Click on the storage account name noted in step 4. This will open blade specific to that storage account
  7. In Section Blob Service click Containers. It will list all the containers in next blade
  8. Look for a record with container named as insight-operational-logs. Click ... from right most column to open Context menu
  9. Click Access Policy from Context Menu and ensure Public Access Level is set to Private (no anonymous access)
