Cisco 11503 Listening ports

Recently done a port scan on CSS.

Any idea how I can closed of the listening ports TCP 1720, 1863 and 3128?

Are these ports used by CSS for internal comms?

Please advise

We do not listen to those ports.

[root@Linux2 cisco]# telnet 192.168.20.120 1720

Trying 192.168.20.120...

telnet: connect to address 192.168.20.120: Connection refused

Do you have a 0.0.0.0/0:1720 content rule ?

Do a 'sho rule-summary' to check.
