# How your CA first became aware of the problem (e.g. via a problem report submitted to your Problem Reporting Mechanism, a discussion in the [https://groups.google.com/a/mozilla.org/g/dev-security-policy MDSP mailing list], a Bugzilla bug, or internal self-audit), and the time and date.
# A timeline of the actions your CA took in response. A timeline is a date-and-time-stamped sequence of all relevant events. This may include events before the incident was reported, such as when a particular requirement became applicable, or a document changed, or a bug was introduced, or an audit was doneperformed.
# Whether your CA has stopped, or has not yet stopped, certificate issuance or the process giving rise to the problem or incident. A statement that you have stopped will be considered a pledge to the community; a statement that you have not stopped requires an explanation.
# In a case involving certificates, a summary of the problematic certificates. For each problem: the number of certificates, and the date the first and last certificates with that problem were issued. In other incidents that do not involve enumerating the affected certificates (e.g. OCSP failures, audit findings, delayed responses, etc.), please provide other similar statistics, aggregates, and a summary for each type of problem identified. This will help us measure the severity of each problem.
# In a case involving TLS server certificates, the complete certificate data for the problematic certificates. The recommended way to provide this is to ensure each certificate is logged to CT and then list the fingerprints or crt.sh IDs, either in the report or as an attached spreadsheet, with one list per distinct problem. It is also recommended that you use this form in your list "<nowiki>https://crt.sh/?sha256=[sha256-hash]</nowiki>", unless circumstances dictate otherwise. When the incident being reported involves an SMIME certificate, if disclosure of personally identifiable information in the certificate may be contrary to applicable law, please provide at least the certificate serial number and SHA256 hash of the certificate. In other cases not involving a review of affected certificates, please provide other similar, relevant specifics, if any.
# Explanation about how and why the mistakes were made or bugs introduced, and how they avoided detection until now.
# List of steps your CA is taking to resolve the situation and ensure that such situation or incident will not be repeated in the future. The steps should include the action(s) for resolving the issue, accompanied by a binding timeline the status of when your CA expects to accomplish each of these remediation stepsaction, and the date each action will be completed.
The purpose of these incident reports is to provide transparency about the steps the CA is taking to address the immediate issue and prevent future issues, both the issue that originally led to the report, and other potential issues that might share a similar root cause. Additionally, they exist to help the CA community as a whole learn from potential incidents, and adopt and improve practices and controls, to better protect all CAs. Mozilla expects that the incident reports provide sufficient detail about the root cause, and the remediation, that would allow other CAs or members of the public to implement an equivalent solution.
