Abstract

I will attempt 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.

1.1 Introduction

This paper will provide an in-depth analysis of known port scan methods, with exhaustive information for each technique used in the wild today to map and identify open and closed ports on various network servers.

Note: This paper will not describe techniques used to fingerprint operating systems nor identify daemon versions (banner scanning).

With an epidemic of port scan instances occurring each and everyday, it should be recognized the ways an attacker could probe network hosts using a variety of techniques aimed to avoid detection whilst obscuring the sender's true source.......
