Describe cyber attacks that could affect a computer system or network : Hidden Scanning Ports with Nmap

This video tutorial covers the use of Nmap for network scanning, both for legitimate and hacking purposes. It explains basic and advanced scanning techniques, including the use of parameters to identify open ports, operating systems, and services. The tutorial also introduces Zenmap, a graphical interface for Nmap, and discusses stealth scanning techniques to avoid detection. The video emphasizes the importance of understanding Nmap's capabilities for both network troubleshooting and cybersecurity.

What is the primary purpose of using Nmap in network security?

• To create network diagrams

• To encrypt network traffic

• To troubleshoot network issues

• To scan for open ports and vulnerabilities

Which Nmap parameter provides verbose output during a scan?

• -sS

• -O

• -v

• -A

What does the -O parameter in Nmap do?

• Increases scan speed

• Scans for open ports

• Detects the operating system

• Performs a stealth scan

What is Zenmap?

• A network encryption tool

• A graphical interface for Nmap

• A vulnerability assessment tool

• A command-line tool for network scanning

Which scan type in Zenmap is known for being comprehensive?

• Stealth scan

• Regular scan

• Intense scan

• Quick scan

What is the purpose of using the -sS parameter in Nmap?

• To perform a full TCP connect scan

• To perform a stealthy SYN scan

• To detect the operating system

• To increase scan verbosity

Why is it important to choose the appropriate T parameter in Nmap?

• To ensure the scan is completed quickly

• To avoid detection by the target network

• To increase the number of open ports found

• To improve the accuracy of OS detection
