Speeding up nmap service scanning 16x::In my previous post post, I began writing about how I was designing a port and service scanner for large-scale networks by combining port-scanning tools like masscan/zmap and service scanning tools like nmap. In this post, I’m going to dive into some of the details of nmap’s service scanning, and outline how I was able to speed up nmap’s service scanning by 16-times.
