== Why is this an issue?

=== What is the potential impact?
|
||
|
|
|
||
|
|
Access keys are used to authenticate to Azure Event Grid resources and can be
|
||
|
|
employed for event publication to the resource.
|
||
|
|
|
||
|
|
Shared Access Secrets (SAS) are generated from access keys and used to
|
||
|
|
authenticate specific resources with particular permissions within a defined
|
||
|
|
time frame. +
|
||
|
|
Using Shared Access Signatures is always better than using access keys,
|
||
|
|
because they reduce risk thanks to their scope and time limitation.
|
||
|
|
However, hardcoding secret tokens is always a bad practice, and still
|
||
|
|
exposes the resources to attacks. +
|
||
|
|
This is a risk unless the whole resource is free of sensitive data.
|
||
|
|
|
||
|
|
Note that the Microsoft docs can use different terminologies for these
|
||
|
|
two tokens:
|
||
|
|
|
||
|
|
* Access Keys are also called SAS keys
|
||
|
|
* Shared Access Secrets are also called SAS tokens
|
||
|
|
|
||
|
|
Below are some real-world scenarios that illustrate some impacts of an attacker
|
||
|
|
exploiting these types of secrets.
|
||
|
|
|
||
|
|
// Set value that can be used to refer to the type of secret in, for example:
|
||
|
|
// "An attacker can use this {secret_type} to ..."
|
||
|
|
:secret_type: secret
|
||
|
|
|
||
|
|
// Where possible, use predefined content for common impacts. This content can
|
||
|
|
// be found in the folder "shared_content/secrets/impact".
|
||
|
|
// When using predefined content, search for any required variables to be set and include them in this file.
|
||
|
|
// Not adding them will not trigger warnings.

On top of that, use the Azure SDK as much as possible and their diverse
|
||
|
|
credential objects.
