# Cardano security and incident response

Intersect facilitates Cardano's incident response capability through a structured framework of policies, roles, and processes maintained by its Security Council.

Intersect, in conjunction with its steering committees and executive, appoints the Security Council, which reports to the Technical Steering Committee. The Security Council oversees a security policy on behalf of ecosystem, manages incident response, and coordinates with contributing organizations when issues arise, across the repositories under its stewardship. It operates through a defined set of roles: a Security Manager who receives and triages reports, Responders who are the directly responsible individuals for resolving specific issues, and Insiders — vetted contributors granted access to sensitive information on a need-to-know basis. This structure is designed to contain sensitive information while enabling a fast, coordinated technical response.

Intersect also operates a Bug Bounty Program to encourage responsible disclosure of vulnerabilities before they can cause harm.

For extreme scenarios, Intersect's Security Council will invoke CIP-135, Cardano's formal disaster recovery framework. CIP-135 defines procedures for situations where the protocol's built-in recovery mechanisms are insufficient. The framework is exercised regularly through fire drills on the SanchoNet testnet. It was held on standby during the November 2025 chain partition incident. However, it was not needed, as the network recovered through coordinated node upgrades.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.intersectmbo.org/intersect-knowledge-base/cardano-facilitation-services/cardano-development/cardano-security-and-incident-response.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
