    Port Scanning

    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.
