This is a new message, which was implemented in the PCS OS for 6.0R4, 6.1R3, and 6.2R1 and later versions of the PCS OS:
Minor AUT24604 <date> <time> - ive - [<IP>] IVSname::System() - SSL negotiation failed while client at source IP '<IP>' was trying to connect to '<IP>' . Reason:<reason_inserted_if_available>'
This occurs due to the client trying to negotiate a connection, by using an unsupported piece of the SSL connection. This could be the initial SSL version or protocol, which was attempted. For example, if you enable SSL v3 and TLS v1 and the client connects (only or initially) with SSL v2, you will see this message.
There is no concern with this message; however, it can be disabled, if you do not want to have this message occurring frequently in the log file. To disable:
- Enable the Do not allow connections from browsers that only accept weak ciphers option, which is located under System > Configuration > Security.
- Disable Connection Requests, which is located under System > Log/Monitoring > Events Log > Settings.
The reason string will be blank, if there is no additional information available beyond that the failure occurred. There are multiple attempts logged per user per connection. Each client connection will also generate this message.
