syslog SSL support TLS 1.2 ??

Sentinel 8.6.1

event source server: TrendMicro Deep inspector

condition:

    because trendmicro production provide a function to match PCI-DSS requirement...so it must send log by TLS1.2 only.

but it configure send log to senitnel syslog SSL (TCP1443) ....no log send to log server.

Whether  the sentinel's syslog SSL support TLS1.2 or not ?

thanks!!

    You could always test the connection.  For example using openssl ...

    openssl s_client -connect sentinel.domain.com:1443 -tls1_2
