These detections are designed to inform and alert network administrators about irregularities that could impact network functionality or indicate potential vulnerabilities. For example, the 6in4tunnel detection flags IPv6 traffic tunneled over IPv4, which, while not inherently harmful, could be exploited for covert communication. The alltcpflags detection alerts when all TCP flags are set, an unusual condition often associated with network scanning or evasion techniques. While these detections may not always signify an imminent attack, they serve as critical informational tools for maintaining network hygiene and preemptively addressing potential security risks. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.fusion.vectra.ai/detection-models/library/informational.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. 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.
