The Complete Nmap Ethical Hacking MasterClass

Explore how local networks connect devices via modems and wifi, and learn to map and scan with Nmap for open ports, operating systems, and vulnerabilities.

Explore how ports function as access points for network services, showing how IP addresses and port numbers identify specific services, and how port scanning reveals open or closed ports.

Learn about the top 20 open tcp ports and their roles, including telnet 23, ftp 21, ssh 22, smtp 25, dns 53, and https 443.

Learn the top 20 most commonly open UDP ports, including dhcp, dns, ntp, ipsec, snmp, netbios, and upnp discovery, with practical notes for secure scanning in the Nmap MasterClass.

Perform a service version scan with Nmap using the -sV flag to reveal running software versions on open ports, guiding vulnerability assessment.

Learn how to save nmap scan results to a text file, name the output, and verify the saved data, with a glimpse at saving to XML in a future lesson.

Learn to log nmap scans with the -oA flag to generate three log files: text, image, and gnmap, and search them to find open ports and timing data.

learn to use nmap to scan specific ip ranges and ports, including default top 1000 ports, and customize port ranges with the -p flag for full 1-65535 scans.

Master ping-agnostic Nmap scanning to enumerate every host in a target range, including port ranges, uncover open ports and services even when ping fails, and perform complete port scans.

Learn to perform operating system detection with Nmap by leveraging a fingerprint database to identify target systems across a network, including confidence estimates for the detected OS.

Learn basic ping scanning with nmap on a local area network to identify which hosts are up, reveal mac addresses, and show how root privileges enhance results.

Demonstrate UDP ping and UDP scan by sending UDP packets to a host and observing responses to distinguish blocked traffic on strong systems from open ports on weak systems.

Explore icmp timestamp requests and how targets block responses, using a Windows 7 example with nmap and sudo, then speed scans with timing options T4, T3, and T2.

Learn to perform UDP port scans with nmap and enable version detection to identify running services. Adjust speed with timing options and scan a whole network for comprehensive results.

Learn how Nmap classifies ports into six states—open, closed, filtered, and the combined open or filtered and closed or filtered—and how these classifications guide detection and security considerations.

Explore the Nmap scripting engine (NSE) documentation, uncovering script categories such as authentication, discovery, brute force, and exploit, with guidance on choosing and learning from the NSE repository.

Use Nmap with NSE scripts to geo-locate targets by IP, leveraging IP geolocation, IP info db, and geo bytes to reveal coordinates and attacker location.

Learn to use expressions and arguments in NSE to exclude exploit and intrusive scripts, and to combine broadcast and discovery categories for targeted scans.

Learn to monitor nmap scan progress on large networks using timed intervals to observe state updates and completed results during slow scans.

Detects which http methods a website supports using nmap with the http-methods script on https ports, revealing supported methods such as get, post, and options.

Discover how to locate directories on a web server using network scanning tools and scripts, identify interesting folders within a target address, and interpret scan results.
