IDS rule for NMAP or other scanners

Hello Community !

Do we have an IDS signatures for Port scanners like NMAPS ? we know that those programs can use different flags(RST, ACK, SYN, FIN...)  while its scanning some services etc.  

Also can someone explain me whats means source and destination in DDOS SETTINGS ? DOCS which i have found arent helpful:

  • Every time im asking about some CRUCIAL features from security prespective Ive got an answer "a roadmap" :D  so thats pity that i cant block most scans  from outside of the network(WAN). but regarding DDOS - Im totally agreee with ya  but i havent found any usefull information(explain) in docs thats why im asing. Btw if i'll set Source: 

    Lets say i'll try ping 1.1.1.1 then i can get:

    Ive thought also that "Source is from WAN" but im not sure regarding the test which im getting results of.

  • The Source isn't the WAN, The Source & Destination depends on the flow of the traffic.

    If your computer is doing a ping to 1.1.1.1, then your computer is the Source, and the 1.1.1.1 is the destination.

  • hm... then im wrong. I thought that i can control how some service can reach(ping) me from WAN  how many requests can be respond.
