What port which is used for connection between Managed Host-based Security agent and management server?
TCP 443 and TCP 80 are used for connection between the agent of Managed Host-based Security and the management server.
Although it seems to be a specification that communicates using HTTP(S), actually it communicates encrypted TCP communication rather than HTTP(S) by using ports 443 and 80.
