You are testing device behind IDS. Which Nmap command is most appropriate to use:
nmap -T0
nmap -T5
nmap -T6
None of them. Nmap doesn't work behind IDS
Nmap adjusts its timings automatically depending on network speed and response times of the victim. However, you may want more control over the timing in order to create a more stealthy scan, or to get the scan over and done with quicker. Paranoid (or -T0) scan will wait (generally) at least 5 minutes between each packet sent. This makes it almost impossible for a firewall to detect a port scan in progress, but will also take an extremely long time to finish scanning multiple hosts. >> Poorly worded - where is the attacking device in relation to the IDS?
