Reconnaissance (Recon) is the initial phase of a cyberattack where attackers gather information about a target system or network. This process involves scanning, mapping, and researching to identify potential vulnerabilities, open ports, or weak points that could be exploited. Recon can include both passive methods, like searching public records, and active methods, such as probing systems for responses. The goal is to collect as much useful data as possible to plan and execute further attacks. Understanding reconnaissance helps organizations recognize early warning signs and strengthen their defenses.
