all the standard IEP Policy Files. IEP Policy Files are shared network-accessible IEP policies that anyone else can use in their platform. We recommend you investigate the IEP TLP Policy File first, as TLP very commonly used within the intelligence sharing community.</p> <h2 id="FIRST-TLP-Policies">FIRST TLP Policies</h2> <p>The FIRST IEP-SIG IEP 2.0 TLP Policies are designed to extend and codify each Traffic Light Protocol (TLP) level within a matching Information Exchange Policy. Each IEP-SIG TLP policy is aligned as much as possible with the information exchange requirements of the relevant TLP level. This was purposely done to allow implementers and platform developer to reuse these standard Policy Files in their own products. We hope these become the standard way that threat intelligence producers inform recipients of how they can use the information they receive.</p> <table> <thead> <tr> <th>FIRST IEP-SIG IEP 2.0 TLP Red Policy File</th> <th></th> </tr> </thead> <tbody> <tr> <td>Policy Name</td> <td>FIRST IEP-SIG IEP TLP Red</td> </tr> <tr> <td>Policy ID</td> <td>5e607e88-ab70-4977-8c1b-ee3a16b0f68c</td> </tr> <tr> <td>Policy URL</td> <td><a href="https://www.first.org/iep/2.0/first-tlp-iep.iepj">first.org/iep/2.0/first-tlp-iep.iepj</a></td> </tr> </tbody> </table> <table> <thead> <tr> <th>FIRST IEP-SIG IEP 2.0 TLP Amber Policy File</th> <th></th> </tr> </thead> <tbody> <tr> <td>Policy Name</td> <td>FIRST IEP-SIG IEP TLP Amber</td> </tr> <tr> <td>Policy ID</td> <td>01bc4353-4829-4d55-8d52-0ab7e0790df9</td> </tr> <tr> <td>Policy URL</td> <td><a href="https://www.first.org/iep/2.0/first-tlp-iep.iepj">first.org/iep/2.0/first-tlp-iep.iepj</a></td> </tr> </tbody> </table> <table> <thead> <tr> <th>FIRST IEP-SIG IEP 2.0 TLP Green Policy File</th> <th></th> </tr> </thead> <tbody> <tr> <td>Policy Name</td> <td>FIRST IEP-SIG IEP TLP Green</td> </tr> <tr> <td>Policy ID</td> <td>3903ce63-674c-4b70-9457-8c5527dd9115</td> </tr> <tr> <td>Policy URL</td> <td><a href="https://www.first.org/iep/2.0/first-tlp-iep.iepj">first.org/iep/2.0/first-tlp-iep.iepj</a></td> </tr> </tbody> </table> <table> <thead> <tr> <th>FIRST IEP-SIG IEP 2.0 TLP White Policy File</th> <th></th> </tr> </thead> <tbody> <tr> <td>Policy Name</td> <td>FIRST IEP-SIG IEP TLP White</td> </tr> <tr> <td>Policy ID</td> <td>0d783790-b221-40c1-840a-5787330612c1</td> </tr> <tr> <td>Policy URL</td> <td><a href="https://www.first.org/iep/2.0/first-tlp-iep.iepj">first.org/iep/2.0/first-tlp-iep.iepj</a></td> </tr> </tbody> </table> <h2 id="FIRST-IEP-SIG-Unknown-IEP">FIRST IEP-SIG Unknown IEP</h2> <p>The FIRST IEP-SIG have also created a network accessible copy of the Unknown IEP Policy.
