| The [https://www.mozilla.org/en-US/about/governance/policies/security-group/certs/policy#4-common-ca-database Common CA Database (CCADB)] uses an Audit Letter Validation (ALV) tool to automatically parse and validate audit statements. This system eliminates manual processing, but it requires audit statements to follow some basic rules in order to function properly.

| * [https://www.ccadb.org/policy#51-audit-statement-content Audit Statement Requirements and Format Rules] - If an audit statement fails to meet any of these requirements, the CA will be asked to work with their auditor to provide an audit statement that passes ALV.

To provide this information for root certificates, [https://www.ccadb.org/cas/updates#audit-case-workflow create one Audit Case] in the CCADB for a particular set of audits (e.g. Standard Audit, BR audit, EV Audit). Then create a set of corresponding Root Cases, one per root certificate, to tell the CCADB which Root Certificate records the audit statements in that Audit Case apply to.

To provide this information for intermediate certificates, directly update the corresponding record in the CCADB then click on the "Audit Letter Validation [ALV]" button.

| == ALV on Intermediate Certificate Records ==
| |
| The following two fields are set by running ALV on an intermediate certificate record in the CCADB. CAs may cause ALV to be run on the record by clicking on the "Audit Letter Validation [ALV]" button. Additionally CCADB has automated processes that will regularly check for intermediate certificate records that need to have ALV run.

| # Standard Audit ALV Found Cert
| |
| #* This field will be set to PASS when ALV finds the SHA-256 Fingerprint for that certificate in the standard audit statement.
| |
| # BR Audit ALV Found Cert
| |
| #* This field will only be set when the "Derived Trust Bits" field has 'Server Authentication' in its list.
| |
| #* This field will be set to PASS when ALV finds the SHA-256 Fingerprint for that certificate in the BR audit statement.

| Subordinate CAs who operate non-[https://www.mozilla.org/en-US/about/governance/policies/security-group/certs/policy/#531-technically-constrained technically-constrained] intermediate certificates have the keys to the internet just as much as the [[CA/Included_CAs|CAs who have root certificates directly included in Mozilla's root store]]. Meaning that such subordinate CAs can also issue TLS certificates for any website or domain, so it is imperative that the same rules are being followed by all subordinate CAs operating non-[https://www.mozilla.org/en-US/about/governance/policies/security-group/certs/policy/#531-technically-constrained technically-constrained] intermediate certificates.

| There are currently about 150 [[CA/Included_Certificates|root certificates in Mozilla's root store]] , which leads to about 2,500 [[CA/Intermediate_Certificates|intermediate certificates]] that are trusted by Mozilla's root store. To help enforce the rules at the intermediate certificate level, Mozilla requires disclosure of non-[https://www.mozilla.org/en-US/about/governance/policies/security-group/certs/policy/#531-technically-constrained technically-constrained] intermediate certificates in the CCADB, which automatically runs ALV on them and reports the results to CAs and root store operators in their CCADB home page.
