1. What actually happened or you saw:
I don’t know if CIS can prevent DoS (FLOOD) type of attacks
2. What you wanted to happen or see:
A DoS filter in COMODO (if not already implemented)
3. Why you think it is desirable:
DoS Protection, like some routers have
4. Any other information:
No, just comment if you think it’s a good idea, or if comodo already has it, how the user can benefit from it. Thank you 
It might offer peace of mind, but I don’t know how practical DoS flood attack detection is. If Comodo blocks every unsolicited packet by nature of being a firewall, isn’t DoS attack detection redundant? However it might be useful for logging purposes for instance if you have a PC on your network that becomes infected with a worm, or a malicious user tries to penetrate one of your PCs by initiating a port scan.
Pointless considering your connection will still be affected as a DoS attack needs to be stopped further upstream closer to the source of the attack which can be done by your or the attacker ISP. Also the firwall will not allow packets pass through to the OS unless the packet is part of a legitimate connection or you have a rules set to allow incoming connections on the the given port.
