# Reconnaissance Reconnaissance detections are an essential component of Netography Fusion's Netography Detection Models (NDMs) that are designed to identify and alert network administrators to activities associated with scanning and reconnaissance. These detections help identify potential attackers who are seeking information about the network and its infrastructure. For example, the system can detect Port Scanning and Service Enumeration attempts, which indicate an attacker is trying to identify open ports and the services running on them. The detection of OS Fingerprinting attempts can identify an attacker's attempt to learn more about the target operating system and any associated vulnerabilities. By identifying these reconnaissance activities, the system can alert network administrators to the presence of potential threats and enable them to take the necessary steps to mitigate these threats before they escalate into a full-blown attack. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.fusion.vectra.ai/detection-models/library/reconnaissance.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
