Microsoft Azure Sentinel: Adding TLPs (Traffic Light Protocol) to Incidents, Alerts and Analytics Rules.
Just like we label documents, it would be nice to label incidents or rules with the TLP so people instantly know if something can or can’t be shared.
Below is an example what we could be doing to enhance our Sentinel Environment.
Analytics Rules Description:
Incident Triggered
How to use
Description
You can use and add the following HTML to the Analytics rule description
<div style="background-color: #000;border-left: 3px solid #f44336;"><p style="padding: 5px">🚦 <strong style="color:#FF2B2B">TLP:RED - Not for disclosure, restricted to participants only</strong></p></div><p style="padding:3px;border:1px solid #f44336;background-color:#fefefe">Sources may use TLP:RED when information cannot be effectively acted upon without significant risk for the privacy, reputation, or operations of the organizations involved. For the eyes and ears of individual recipients only, no further.
<br>
Recipients may not share TLP:RED information with any parties outside of the specific exchange, meeting, or conversation in which it was originally disclosed. In the context of a meeting, for example, TLP:RED information is limited to those present at the meeting. In most circumstances, TLP:RED should be exchanged verbally or in person.</p>
<div style="background-color: #000;border-left: 3px solid #FFC000;"><p style="padding: 5px">🚦 <strong style="color:#FFC000">TLP:AMBER+STRCIT - Limited disclosure, restricted to participants’ organization</strong></p></div><p style="padding:3px;border:1px solid #FFC000;background-color:#fefefe">Sources may use TLP:AMBER+STRICT when information requires support to be effectively acted upon, yet carries risk to privacy, reputation, or operations if shared outside of the organization.

Note that TLP:AMBER+STRICT should be used to restrict sharing to the recipient organization only.

Incident Comments
Create a Logic App and add the TLPHTML you want to use:
We need to do some transcoding so that the HTML gets parsed
Finally, add the Playbook to be used:
And there you have it! Easy tagging of your alerts, incidents and rules with TLP as needed.
