Forresters "NAV" (Network Analysis & Visibility) is a term I prefer rather than the the concept (misconception) of NDR (Network Detection and Response). I've yet to see any organisation deploy the "R", certainly from an automated perspective anyway ! Maybe just too risky a step ? However there are ways to get closer to this small "r".

What I Learned Today About Network Scanning with Nmap Today, I delved into network scanning and security with Nmap, an essential tool for any cybersecurity professional. Here are some key insights I'm taking with me: Types of Scans: SYN Scan ("Half-Open" or "Stealth"): This scan sends SYN requests only without completing the full TCP handshake. It’s faster and less detectable by older IDS systems. This scan allows us to efficiently and quickly gather information about open ports on the target system. Command: sudo nmap -sS <target_ip> UDP Scan: This scan is slower and more challenging due to the lack of response from open ports. It marks ports as "open|filtered" if no response is received. This command helps us identify services listening on UDP ports that do not respond like TCP ports. Command: sudo nmap -sU <target_ip> Special Scans - NULL, FIN, and Xmas: These scans are considered stealthier and are used to avoid firewalls and IDS systems. These scans use different TCP flags to try and evade detection systems. Commands: sudo nmap -sN <target_ip>, sudo nmap -sF <target_ip>, sudo nmap -sX <target_ip> Firewall Evasion: Ping Sweep Scan with -Pn: This bypasses firewalls that block ICMP by scanning without sending ping requests. This switch allows Nmap to assume the target is alive and proceed with port scans. Command: sudo nmap -Pn <target_ip> Using Switches like -f and --mtu: Fragmenting packets or changing packet size to avoid detection. The -f switch is used to fragment packets, while --mtu provides control over packet size. Commands: sudo nmap -f <target_ip>, sudo nmap --mtu <number> <target_ip> Using the Nmap Scripting Engine (NSE): I learned how to use different scripts to extend Nmap’s scanning capabilities. Using NSE allows running scripts for vulnerability checks, service detection, and more. Example command: sudo nmap --script ftp-anon -p 21 <target_ip> Practical Exercises: Performing SYN, UDP, and Xmas scans on various ports and analyzing results: I scanned a range of ports and learned how to interpret the results to understand which services are running on the target. Understanding how to bypass firewalls and use advanced scan switches: I analyzed scans using SYN, FIN, Null, and Xmas flags to understand techniques for evading firewalls and IDS. Using switches like -Pn to bypass firewalls blocking ICMP: I learned how to run scans in scenarios where ping requests are blocked. Summary: Thank you to everyone who contributed to these learning resources and amazing tools! On TryHackMe, I’m excited to continue deepening my knowledge in cybersecurity and make use of tools like Nmap to protect systems and discover vulnerabilities. #cybersecurity #infosec #networksecurity #nmap #pentesting #ethicalhacking #cyberawareness #cyberdefense #hacking #itsecurity #tryhackme #securitytools #vulnerabilityassessment #techskills #learning
