  • Service does not generate SAS client constructs it using the shared key “keep track of who gets your storage account shared keys”

    There are 2 pillars the SAS token stands on the shared key and (if used) the stored access policy

    remove either and the SAS token is invalid, so user can regenerate their keys and all SAS tokens will become invalid then they can start from a clean slate otherwise if they remove the stored access policy (and don’t recreate it with the same name), the SAS token becomes invalid without affecting other tokens that don’t depend on the stored access policy

     Note: Currently, an account SAS must be an ad hoc SAS. Stored access policies are not yet supported for account SAS.


    Controlling a SAS with a stored access policy

    A shared access signature can take one of two forms:

    • Ad hoc SAS: When you create an ad hoc SAS, the start time, expiry time, and permissions for the SAS are all specified in the SAS URI (or implied, in the case where start time is omitted). This type of SAS can be created as an account SAS or a service SAS.
    • SAS with stored access policy: A stored access policy is defined on a resource container--a blob container, table, queue, or file share--and can be used to manage constraints for one or more shared access signatures. When you associate a SAS with a stored access policy, the SAS inherits the constraints--the start time, expiry time, and permissions--defined for the stored access policy.

  • Hi Sumanth/ Marcin,

    I was able to perform the following.

    Please let me know if the approach is correct, in case I wish to know who requested for SAS token.

     1. Open any Azure storage account

    2. Select the feature 'Alerts'

    3. Create an alert rule by selecting the condition "All administrative Operations"   

    4. Observe alert(s) under the defined severity level

       Alerts -> Severity 4 -> All Alerts -> <<Select the Alert> -> More Details -> Use 'Caller' and 'Submission Timestamp'

     Could you suggest the ideal solution / better solution that is generally used.

    Kind regards,

    Murugan
