How to find every device on network with NMAP?












0















As a beginner to NMAP, my interest is using it on a local network to find any rogue device, whether it be connected for malicious or non malicious reasons. From my understanding of NMAP, the only way to be 100% certain beyond a shadow of a doubt that a host discovery, or "ping sweep" will find all devices on the network (especially malicious rogue devices trying to hide) would be to have NMAP do a scan in the network's IP range that includes:




  • SYN ping of every port

  • ACK ping of every port

  • UDP ping of every port

  • ICMP echo request, timestamp query, and address mask query (-PE, -PP, -PM)

  • IP Protocol ping for every protocol

  • ARP Scan


With this, the only other factor limiting NMAP's ability to detect an online host could be data lengths of packets sent (specified by --data-length). Otherwise, if a device is connected to the network being scanned, it will not be able to hide from NMAP. Is this assumption correct?
