Technical Details

what runs on :9593

The CBA8 management-agent service is registered on both TCP and UDP port 9593. It uses a proprietary LANDesk Common Base Agent protocol for endpoint-management traffic; exact message framing and connection behavior depend on the LANDesk/Ivanti product version and deployment. Related LANDesk agent services may use nearby ports, including 9594 and 9595, so identifying the product should consider the complete port set rather than 9593 alone.

security overview

This is a remote-management service and should normally be restricted to LANDesk/Ivanti management servers and trusted administrative networks, not exposed to the public internet. An exposed instance can disclose that endpoint-management software is installed and may provide an attack surface for agent authentication, inventory, or management operations; apply vendor updates and enforce network access controls.
