1. Conduct nmap TCP half-open stealth scan
   • Instructions:
     1. nmap -sS 192.168.1.106
   • Notes:
     • Obtain the IP Address of the Window 7 machine running Comodo from (Section 3, Step 2).
     • -sS, This technique is often referred to as half-open scanning, because you don't open a full TCP connection. You send a SYN packet, as if you are going to open a real connection and then wait for a response. It is also relatively unobtrusive and stealthy since it never completes a TCP connections.
   • 
2. Viewing Comodo Results

     1. Click the allow button until no more alerts are displayed.
   • Notes:
     • Notice you were still alerted when nmap uses a half-open TCP scan.

   • Notes:
     • This technique is often referred to as half-open scanning, because you don't open a full SCTP association. You send an INIT chunk, as if you are going to open a real association and then wait for a response.
     • SCTP is a relatively new alternative to the TCP and UDP protocols, combining most characteristics of TCP and UDP, and also adding new features like multi-homing and multi-streaming. SCTP INIT scan is the SCTP equivalent of a TCP SYN scan. It can be performed quickly, scanning thousands of ports per second on a fast network not hampered by restrictive firewalls. Like SYN scan, INIT scan is relatively unobtrusive and stealthy, since it never completes SCTP associations.
