Top 5 Advanced Nmap Scans | Nmap Tutorials for Beginners

1. Save Scan Results to text file (Not allowed to use angle brackets in Youtube description replace right_arrow with right arrow or right angled brackets. Refer to the video) nmap 192.168.1.254 right_arrow scans.txt nmap 192.168.1.254 right_arrow right_arrow scans.txt (Append multiple scans to same text file) 2. How to Perform an Aggressive Scan nmap -A 192.168.1.254 The Aggressive scan is a comprehensive scan that combines various Nmap features to gather extensive information about the target. It includes OS detection, version detection, script scanning using the Nmap Scripting Engine (NSE), traceroute, and other advanced scanning techniques. This scan provides a thorough analysis of the target's operating system, running services, and potential vulnerabilities. 3. Fast Scan - Scans 100 most common ports nmap -F 192.168.1.254 4. The TCP SYN scan, also known as the half-open scan, is one of the most popular Nmap scans. It sends SYN packets to the target's specified ports and observes the response. If a port is open, the target should respond with a SYN-ACK packet. The half-open approach avoids completing the TCP three-way handshake, making it faster and stealthier, as some Intrusion Detection Systems (IDS) may not log it. nmap -sS 192.168.1.254 5. The Scan Delay: Slowing down the scan with the --scan-delay option reduces the number of packets sent per second, making the scan less likely to trigger alarms. nmap -sS --scan-delay 200ms 192.168.1.254 6. Fragment packets (Bonus scan) : Using the -f option, Nmap can send fragmented IP packets. This can sometimes bypass certain firewall or IDS filters. nmap -f 192.168.1.254 Disclaimer: All demonstrations in this video are conducted on authorized systems with explicit permission.
