AuthorJeremy Conway

Total time: 34 minutes

Passive operating system fingerprinting is a method for passively detecting the operating system of a remote host based on certain characteristics within that host's network stack. Due to the passive nature of this analysis, the remote system being fingerprinted cannot detect this style of reconnaissance. In this learning module we will examine several common metrics utilized to perform passive operating system fingerprinting and some of the most common applications and/or tools that can perform this type of reconnaissance.
