Cyber security Kill Chain: Active Reconnaissance Overview, Methodology and Tools

Reconnaissance is the first in the cyber security kill chain and it involved both passive and active techniques to obtain information about a target. Once an attacker has used Opensource Intelligence (OSINT) for passive reconnaissance, they generally move on to active techniques of information gathering that involve direct interaction with a target. In this video, we'll discuss active the active reconnaissance methodology and review tools and techniques for gathering information we can use for the next step in the kill chain.
