Using Nmap for Pentesting

Get to grips with the power of Nmap in this three-video course on using Nmap for pentesting.

Course description

Nmap is one of the most important tools in the pentester’s arsenal, and this is your chance to explore what it can do. In this course, three videos will introduce you to Nmap’s capabilities and some of the different commands it has in its arsenal, including Nmap -sT (TCP connect scan), Nmap -O (enables OS detection by fingerprinting the packet received) and Nmap -T (sets the timing for the scan at one of six levels). Includes demonstration video.

PenTest+ – Applied Nmap

Lab — 00:30:00

A vast number of tools were developed to aid pentesters in identifying and exploiting vulnerabilities ranging from reconnaissance to scanning and persistence. Knowing which tool to use depends on the services running on the target and the vulnerabilities identified. One way to get this information is by using Nmap, a network mapper that identifies active hosts, open ports, software versions, and known vulnerabilities associated with the software.This lab uses Nmap scans and results to provide practical examples on identifying the right tools to use based on the services running on the target machine. The categories covered include:● Scanners● Credential testing tools● OSINT● Web proxies● Social engineering tools● Remote access tools● Networking tools● Mobile tools● MISC

PenTest+ – Nmap and Hping

Lab — 00:30:00

Reconnaissance is the most crucial phase of a penetrations test. If conducted properly, it allows pen testers to limit the scope of potential attack vectors and map the target’s network. Information like the operating system installed on the target host, open ports, and running services helps pentesters identify vulnerabilities, find ways to exploit them, and advise the client on remediating the security holes. Several tools can help obtain this information, with Nmap and hping being some of the best known, reliable, and full-fledged utilities.This lab covers the most commonly used options and flags of Nmap and hping, describing in detail their functionality and usage. The topics covered are:● Nmap○ Port ranges○ Target specification○ Output formats○ Default scripts○ Scan types● Hping○ TCP packet crafting○ UDP packet crafting
