Ep 17. Discovering Open Ports

The show Learning Network Penetration Testing with Kali Linux is a comprehensive guide to mastering the skills required for network penetration testing using Kali Linux. In season 1 episode 17, titled Discovering Open Ports, viewers will learn the basics of detecting open ports in a network.

The host of the show, a seasoned cybersecurity expert, begins by explaining the importance of identifying open ports in a network. Open ports are the entry points through which attackers can gain unauthorized access to a network. Therefore, it is essential to identify all open ports and ensure that only necessary ports are open.

The host then demonstrates how to use nmap, a popular network scanning tool, to discover open ports. Viewers will learn how to use the different options and switches offered by nmap to scan a network and identify all open ports. The host also explains how to use nmap to scan specific ports and hosts.

Once open ports have been identified, the host explains how to determine the services running on those ports. This information is crucial for assessing the vulnerability of the network. The host demonstrates how to use nmap to identify the services running on open ports and how to use other tools like netstat and lsof to get more detailed information.

The next part of the episode focuses on determining the version of the services running on open ports. Knowing the version of a service running on a port can help identify vulnerabilities that can be exploited by attackers. The host demonstrates how to use nmap to determine the version of services running on open ports and how to use other tools like banner grabbing and fingerprinting to get more accurate information.

The host also emphasizes the importance of ensuring that only necessary services are running on open ports. Services like telnet and FTP are often used by attackers to gain unauthorized access to a network. Viewers will learn how to use nmap to identify these services and how to use other tools like Nessus to assess the vulnerability of the network.

The episode concludes with the host summarizing the importance of discovering open ports and the services running on them. Viewers will have learned how to use nmap and other tools to scan a network and identify all open ports and services running on them. They will also have learned how to assess the vulnerability of the network and ensure that only necessary services are running on open ports.

Overall, season 1 episode 17 of Learning Network Penetration Testing with Kali Linux is an informative and practical guide to discovering open ports in a network and assessing the vulnerability of the network. It is a must-watch for anyone interested in cybersecurity and network penetration testing.
