security.txt

A proposed standard which allows websites to define security policies.

Your security.txt file has been copied to your clipboard!

Summary

“When security risks in web services are discovered by independent security researchers who understand the severity of the risk, they often lack the channels to disclose them properly. As a result, security issues may be left unreported. security.txt defines a standard to help organizations define the process for security researchers to disclose security vulnerabilities securely.”

Step 1

Create a text file called security.txt under the .well-known directory of your project.

Contact Required

A link or e-mail address for people to contact you about security issues. Remember to include "https://" for URLs, and "mailto:" for e-mails. See the full description of Contact

Encryption Optional

A link to a key which security researchers should use to securely talk to you. Remember to include "https://". See the full description of Encryption

Acknowledgments Optional

A link to a web page where you say thank you to security researchers who have helped you. Remember to include "https://". See the full description of Acknowledgments

Preferred-Languages Optional Only 1 allowed

A comma-separated list of language codes that your security team speaks. You may include more than one language. See the full description of Preferred-Languages

Canonical Optional Only 1 allowed

The most common URL for accessing your security.txt file. It is important to include this if you are digitally signing the security.txt file, so that researchers can know for sure that you didn't just steal someone else's file with the same content. See the full description of Canonical

Policy Optional

A link to a policy detailing what security researchers should do when searching for or reporting security issues. Remember to include "https://". See the full description of Policy

Hiring Optional

A link to any security-related job openings in your organisation. Remember to include "https://". See the full description of Hiring

Step 2

You are ready to go! Publish your security.txt file. If you want to give security researchers confidence that your security.txt file is authentic, and not planted by an attacker, consider digitally signing the file with an OpenPGP cleartext signature.
