[Progress Communities] [Progress OpenEdge ABL] Forum Post: RE: 00509324-TDE Encryption between Replication sites - does the traffic gets encrypted ove

[Dapeng Wu]

The traffic between a replication source and target database is basically AI notes (in AI blocks). These notes records the changes of actual data in the database. For example, a record has been updated. In TDE, data and AI can be encrypted separately. For example, a table may not be encrypted; but if AI encryption is enabled, then all the AI data, including the ones that record the changes of this non-encrypted table, will still be encrypted. TDE provides encryption for data on disk and in transit. So as Jeff has mentioned earlier, AI encryption will make sure all the sensitive data used by replication is protected. Also note that even with AI encryption enabled, OE Replication will not encrypt all the traffic --- some non-sensitive, administrative network messages will not be encrypted.
