This stores worker connection nonces within the database to ensure
uniqueness of connections. Prior the connection required any attacker to
be able to decrypt the incoming encrypted authentication message in
order to replay (and if the attacker has access to the KMS you have
bigger problems), but with this change even if an attacker does have
access to the KMS key, they cannot reuse the same message. (If they're
able to encrypt against the KMS key, they can still act as a worker with
a new message, so this only really helps if they only have decryption
capabilities.)
* feat (events): Add new options needed for AuditConfig
WithAuditWrapper and WithFilterOperations all for optional paramters
when creating AuditConfig types.
* refactor (event): Change EventerConfig.Sinks to a ptr
We need to modify the SinkConfig.AuditConfig during the NewEventer factory, so we have to use a ptr not a ref.
* feat (events): Add audit configuration types
* feat (events): add audit config to sink configuration.
* feat (events): add redact/encrypt node for audit events to Eventer
Integrate the encrypt.Filter node from the eventlogger into the
event.Eventer, so audit events can be redacted/encrypted based
on data classifications.
* test (events) Add test protobufs for events
Add test protobufs along with a test service for testing
the audit event encrypt node
This moves the generated pb files to the `sdk` module. This allows third parties to make use of them if desired (e.g. in upcoming plugins) and moves away from the `gen` nomenclature in the directory, since we are going to be adding some extra interface functions to the messages.
* Normalize event configuration
This updates event configuration stanzas to more closely match behavior
for listeners and kmses:
* Singular "sink" instead of "sinks" (probably not the most correct
option, but a consistent option, and one that makes sense for HCL)
* Allows sinks to have the type defined at the start of the block
* Moves type-specific configuration to a specific named block
