There is a recent case whereby it was reported that one of the production servers was hacked on port 1521. However, I am not sure how this was possible, as I checked that the OS firewall (iptables) is on :
Port 1521 not open :
However, it is listening on port 1521 :
I assume it is listening because the application is turned on, and thus the service related to port 1521 turned on and that is why it is listening on this port?
Even if the network firewall (physical) is open, if the iptables is running in the server, it should not allow port 1521 to be open/listening?
I can't think of any other way how people can hack the server on port 1521. Please help clear my doubt.
