Evading Firewalls & Enumerate SNMP Using Advanced NMAP Techniques

You've been tasked with learning about a network and its systems, which you have no prior knowledge of. It's an unidentified network. You are required to locate active IP addresses, network interfaces, hosts that are actively executing apps, services, OS & their versions, or even just open or closed ports. But you have no idea at all! NMAP, sometimes known as Network Mapper, can help here. NMAP can be used for reconnaissance so that we can create our TCP packets, send them to the targets, and investigate the network and systems contained within it. When obtaining important information from target networks and systems, you can avoid firewalls and intrusion detection systems. The data gathered can also be utilised to perform penetration testing to look for weaknesses.
