Is the SBC vulnerable to attacks in known ports?

 

 

Hello everybody,

 

Hope you're doing allright,

 

Recently a customer asked if the SBC, with a sip-interface listening SIP in the 80 TCP port, would be vulnerable to non-sip related attacks in such interface or if the sbc would be capable of blocking/ignoring these unwanted interactions from maliscious sources.

 

Do you guys believe the SD would block or this could be a potential threat (e.g. potentential cpu impact)?

 

I don't think that setting up a known port for a sip-interface would be the best idea and wouldn't recommend it.

 

Regarding the non sip attacks, I would say that the sbc would not respond to this traffic in the application layer, but I'm not sure abut the transport layer, I mean, it's still TCP the protocol (and the port) the SBC is using and so is the potential attack. Is the SBC capable of ignore this traffic at this level (transport)?,

Howdy, Stranger!
