Cyber Reconnaissance

Cyber reconnaissance is a cybersecurity term built from the French word “reconnaissance,” which means “surveying” and adapted from the military practice of reconnaissance, conducting an exploratory survey of enemy territory.

Attackers use cyber reconnaissance techniques to identify the easiest digital entry points into their targets. Reconnaissance can include passive activities where an attacker searches for information without compromising the target. Reconnaissance can also be active, where the attacker gains unauthorized access and engages to gather information. Many attacks include both types.

When conducted defensively, cyber reconnaissance helps organizations to understand where and how cyberattackers could gain access to their networks.
