Dear All,
As far as I know, Oracle does not recommend to use default ports for
security purposes. Searching out of Oracle community found that some people
think that it does not matter any more. However, it can have some vulnerability
and, I think, security risk & auditors would not like to see that.
I have found that in 2012 ORacle Tns listener port 1521 had a vulnerability
issue with oracle database 11gR1 and 11gR2, but how about Oracle 12?.
Also, I was searching something similiar for Oracle OAM, SOA, OIM, OAAM, but still cannot
find anything.
Thanks
