Abstract

A method of remote access action includes directing user actions including a first action to a destination device in an industrial control system (ICS) through a terminal server including a memory, a remote access recording component (RARC), and a security center coupled by a communication server through a network connection to the ICS. The terminal server is coupled to a streaming server having a recorded session repository database. The terminal server limits the user to specifically allowed actions and directs actions if allowed enabling user selecting the destination device from a menu that then provides a connection for the first action to be begun. The RARC during the remote session records streams of video of display window content and text representing the first action, combines the text and display window content to generate a combined video output file and stores the file in the session repository database.

Dependent claims

A method of remote access action recording in a video file of a remote session, comprising:

during said remote session directing said remote access actions of a user including a first action to be applied to a destination device located within at least one industrial control system (ICS) through a terminal server including a memory and a remote access recording component (RARC) and a security center that is coupled by a communication server through a network connection to said ICS, wherein said terminal server is coupled to a streaming server having a recorded session repository database, and wherein said terminal server limits said user to only specifically allowed said remote access actions and directing said first action if said specifically allowed that enables said user selecting said destination device from a menu that then provides a connection to said destination device for said first action to be begun;
said RARC during each sampling interval of said remote session:
recording streams of video of display window content as well as text representing said first action;
combining said text and said display window content to generate a single combined video comprising output file, and
storing said combined video comprising output file in said recorded session repository database.
