NMAP Scan Mode

NMAP scan mode speeds can be modified. This settings are valuable when NMAP scanning is performed in sensitive environments such as OT networks.

Scan Mode Description Details
Fast Scan Use Insane(T5) template Enable NMAP fastest Mode
Normal Scan Use Normal(T3) template NEnable NMAP default Mode
Slow Scan Use Normal(T3) template + Scan delay 10seconds Enable NMAP Default Mode and Allow Scan delay times

NMAP OS SCAN

Configure collecting the Node OS information using NMAP.

NMAP TCP SCAN

Configure collecting the Node TCP information using NMAP.

Oprtions Description Details
TCP SYN Scan Scan by TCP Syn No TCP connection required
TCP CONNECT Scan Scan by TCP connection process Twice as many packete as a SYN scan
TCP FIN Scan Scan by TCP FIN BIT set packet Possible to bypass Stateless Firewall
TCP ACK Scan Scan by TCP ACK BIT set packet Can distinguish between Stateful Firewall and Stateless Firewall
TCP NULL Scan Scan by no BIT set on TCP flag header Possible to by pass Stateless Firewall
