What do reconnaissance traffic signatures indicate?

Reconnaissance traffic signatures are indicative of activities where an entity is probing a network to identify potential vulnerabilities. This often involves actions such as port scanning or sending packets to various IP addresses to map out the network structure and identify services running on open ports. Such techniques help attackers gather intelligence about the network, allowing them to plan more targeted attacks.

When analyzing reconnaissance signatures, security professionals look for patterns in traffic that suggest probing activities rather than legitimate communication patterns. This understanding is crucial for implementing security measures and responding effectively to potential threats. Identifying such signatures may allow network defenders to take preventive actions before an actual attack occurs, enhancing the overall security posture of the network.
