Scanning is the second phase of a pen testing engagement, after Planning and Reconnaissance. Scanning uses tools to gather information such as network information and potential vulnerabilities.

Scanning and Internal Reconnaissance

Now that we are inside the network of our target, we will now perform reconnaissance inside the internal network, known as active reconnaissance, in order to reveal which devices are on the network and what potential new targets await.

• We call this active reconnaissance because we are now directly interacting with our target.
• It is also considered internal reconnaissance because we are conducting this internally within the target.
• While inside the network, we can gather the following:
  • Information about the host, known as host enumeration.
  • Information about processes on the system, known as process enumeration.
  • Information about the users on the system.

Scanning

Additionally, we can more aggressively gather information through a process called scanning.

• Scanning is the second phase of a pen testing engagement, after Planning and Reconnaissance. Scanning uses tools to gather information such as network information and potential vulnerabilities.
  • While in our example we scanned our target from inside the network, scanning is often conducted externally, before initial access.
• Nessus, Hping, and Nmap are tools which we often utilize to conduct scanning.
• Zenmap is the GUI version of Nmap. It provides an easy-to-use tool to automate scanning tasks.
• NSEs (Nmap scripting engines) are scripts that are commonly used to test whether a service is vulnerable to an exploit.
• SearchSploit is a command-line utility for Exploit-DB that allows you to take an offline copy of the Exploit Database with you wherever you go.
