Privileged ports, also known as well-known ports, are those in the range of 0-1023, and are typically reserved for services provided by the operating system or important applications. Unusual connections between privileged ports may indicate an attempt to exploit a service or gain unauthorized access to sensitive resources. The wkpsrcdst security event is triggered when a connection is established between two privileged ports (ports in the range of 0-1023) on the network. **What to Look For** Consider source and destination IPs, ports, connection frequency and duration, data transferred, user accounts and authentication, and log files and system events when analyzing the wkpsrcdst event. Compare the connection to normal network behavior and initiate incident response if necessary. **Related MITRE ATT\&CK Categories** [Command and Control: Protocol Tunneling, Technique T1572 - Enterprise](https://attack.mitre.org/techniques/T1572) --- # Agent Instructions This documentation is published with GitBook.

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/post-compromise/wkpsrcdst.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.
