Generate a statistical baseline of normal network activity. Calculates averages, standard deviations, and distributions for connections, bytes, services, and protocols. Use as a reference point to identify deviations that may indicate compromise.
AI agents call zeek_network_baseline to retrieve information from Zeek without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs statistical analysis and metric computation on network security logs to establish baseline profiles. It retrieves and processes data without creating side effects, modifying records, executing external commands, or destructively altering information. The output serves as a reference for anomaly detection.
From the tool's definition Tool generates statistical baselines and calculates metrics (averages, standard deviations, distributions) over existing network data with no modification or deletion capability mentioned.
Attacks that exploit this kind of access
Generate a statistical baseline of normal network activity. Calculates averages, standard deviations, and distributions for connections, bytes, services, and protocols. Use as a reference point to identify deviations that may indicate compromise. It is categorised as a Read tool in the Zeek MCP Server, which means it retrieves data without modifying state.
Register the Zeek MCP server in PolicyLayer and add a rule for zeek_network_baseline: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Zeek. Nothing to install.
zeek_network_baseline is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the zeek_network_baseline rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for zeek_network_baseline. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
zeek_network_baseline is provided by the Zeek MCP server (solomonneas/zeek-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
