What?

Enumeration is listing and identifying the specific services and resources that a target offers.

Why?

Move further and deeper into the scanning process to include security scanning. Enumeration is particularly successful in networks that contain unprotected network resources and services:

  • Network services that are running but not in use.
  • Default user accounts that have no passwords.
  • Guest accounts that are active.

How?

Take information already gathered during reconnaissance (like IP addresses) and during scanning (open ports) and gather as much extended data about targets and services running on targets, using a variety of techniques and tools.

Start with an IP address range, or a specific DNS entry, and the open ports on the system. Use a number of methods to collect information on applications and hosts on the network and on the user accounts used on the network. Make a list of known and reachable services from that source.
