| Summary |
An adversary engages in probing and exploration activities to identify constituents and properties of the target. |
| Prerequisites |
An application must publicize identifiable information about the system or application through voluntary or involuntary means. Certain identification details of information systems are visible on communication networks (e.g., if an adversary uses a sniffer to inspect the traffic) due to their inherent structure and protocol standards. Any system or network that can be detected can be footprinted. However, some configuration choices may limit the useful information that can be collected during a footprinting attack. |
