Examining port scan methods - Analyzing Audible Techniques. This paper attempts to enumerate a variety of ways to discover and map internal/external networks using signature-based packet replies and known protocol responses when scanning. Specifically, this document presents all known techniques used to determine open/closed ports on a host and ways an attacker may identify the network services running on arbitrary servers.
