To be able to intelligently select tools and exploitation methods for an attack, scanning and enumeration can be used to make sure you:

  • Attack only agreed-upon targets
  • Get as much information as possible before increasing depth of attack
  • Identify purpose and type of targets (what services are provided)
  • Have specific information about versions of services running on target systems
  • Categorise target systems


Port scanning or scanning is for collecting information on the network services on a target network. Attempt to find open ports on the target system. Key are the Internet Control Message Protocol (ICMP) and Transmission Control Protocol (TCP) (and the available TCP flags).
