# vnc\_scanning\_internal **Explanation** The vnc\_scanning\_internal Netography detection model (NDM) is designed to identify any internal VNC scanning activity taking place within a network. It works by monitoring traffic on the network and analyzing it for any signs of VNC scanning activity originating from within the network. The NDM can detect both successful and unsuccessful VNC connection attempts. **What to Look For** If the vnc\_scanning\_internal NDM has an event triggered, it is important to analyze the source IP address of the VNC scanning activity and investigate whether the activity was malicious or not. If the activity was not authorized, immediate remediation steps should be taken to prevent any further unauthorized attempts to access the affected system or systems. **Related MITRE ATT\&CK Categories** [Discovery: Network Service Discovery, Technique T1046 - Enterprise](https://attack.mitre.org/techniques/T1046) --- # 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.
