Secure pages (https)2

ChangedWhen a computer opens the controller's address, the controller first tries its secure page (https) and opens it when that computer can reach it, as before. When that computer cannot open the secure page -- the site's network does not let it reach the controller on TCP port 443, or its browser does not trust the controller's certificate yet -- the controller now shows a page that says so, with two choices -- "Open the secure page" and "Continue on the plain page for now" -- and the text for the IT department: let the computers reach the controller on TCP port 443, and install the controller's certificate. The plain page works as before; the computer is asked again after 12 hours.
NewA computer that continues on the plain page is written in the Action Journal, once a day. When computers have used the plain page for 7 days and none of them has reached the secure page, the Action Journal says so and asks for the change by IT.

Update System1

ChangedThe controller installs a file only once it has checked the file's LiquiDynamics signature, whichever way the file comes: Check for Latest Version, Check for Specific Version or Install from a file. A file that carries no signature, or that the controller cannot check, is not installed; the page says why and what to do next. Every release since LQD_R_2_49 is signed by LiquiDynamics.

Security1

ChangedSigning in to the controller over SSH with a password is accepted only from private network addresses and from the controller's own network. Signing in with a key is not changed.
