Parameters
algname
Context Parameters
2.1.201. tls_disallowed_key_exchange (ID: 00200458)
Default Severity
Log Message
TLSALG: Disallowed key exchange.
Explanation
The TLS ALG session will be closed because there are not enough
resources to process any TLS key exchanges at the moment. This
could be a result of TLS handshake message flooding. This action is
triggered by a system that monitors the amount of resources that is
spent on key exchanges. This system is controlled by the advanced
setting SSL_ProcessingPriority.
Gateway Action
close
Recommended Action
Investigate the source of this, and try to find out if it is a part of a
possible attack, or normal traffic.
