Port Scanning

Submitted by Srikanth on Friday, 7 November 200832 Comments

Port Scanning is one of the most popular techniques used by hackers to discover services that can be compromised.

  • A potential target computer runs many ’services’ that listen at ‘well-known’ ‘ports’.
  • By scanning which ports are available on the victim, the hacker finds potential vulnerabilities that can be exploited.
  • Scan techniques can be differentiated broadly into Vanilla, Strobe, Stealth, FTP Bounce, Fragmented Packets, Sweep and UDP Scans.

Port Scanning Techniques


Port Scanning Techniques can be broadly classified into:

  • Open scan
  • Half- open scan
