> Add option for MutualTlsAuthenticator to restrict the certificate age
> ---------------------------------------------------------------------

> Key: CASSANDRA-18951
> URL: https://issues.apache.org/jira/browse/CASSANDRA-18951
> Project: Cassandra
> Issue Type: New Feature
> Components: Feature/Authorization
> Reporter: Francisco Guerrero
> Assignee: Francisco Guerrero
> Priority: Normal
> Time Spent: 2h 40m
> Remaining Estimate: 0h
>
> In {{org.apache.cassandra.auth.MutualTlsAuthenticator}}, we validate that a
> certificate is valid by looking at the identities inside the
> certificate and making sure the identity exists in the identity to role table.
> In some situations we may want to restrict the certificates
> we accept by rejecting certificates older than x amount of days. Some
> certificates can be generated with long expiration dates,
> and this might be undesired when you want to protect against potential
> certificates being compromised. For that reason, it is
> important to add an option, that when configured, we can limit the age of the
> certificate we accept for mTLS authentication.
> When enabled, this will force clients to have to renew certificates more
> frequently, reducing the exposure of a Cassandra cluster
> to leaked certificates.
