Security Fundamentals Flashcards

Which system variable, when set to 0, stops AutoCAD from searching the drawing's own folder for executable files such as acad.lsp?

Answer: LEGACYCODESEARCH

LEGACYCODESEARCH set to 0 (the default) keeps AutoCAD from searching the starting and drawing folders for executables, which blocks a common malware route.

Which system variable controls the trusted domains from which AutoCAD may run JavaScript code?

Answer: TRUSTEDDOMAINS

TRUSTEDDOMAINS lists the domains and URLs allowed to run JavaScript inside AutoCAD.

A colleague emails you a DWG together with an unfamiliar acaddoc.lsp file. What is the safest action?

Answer: Open only the DWG, and review or discard the LSP file before loading it

Unknown auto-loading LSP files can run harmful code, so inspect them before any trusted folder or drawing path can load them.

Which of these file types is NOT covered by SECURELOAD restrictions?

Answer: DWG

SECURELOAD covers executable files such as LSP, FAS, VLX, ARX, DLL, and DVB, not drawing files.

Where in the Options dialog can a user reach the Security Options settings, including SECURELOAD and trusted locations?

Answer: System tab

The Security Options button on the System tab gives access to executable file settings and trusted locations.

Which file pair appears in a shared network folder while a drawing is open, signaling that the file is in use?

Answer: .dwl and .dwl2

AutoCAD creates .dwl and .dwl2 lock files that record who has the drawing open, which helps prevent conflicting edits.

A second user opens a drawing that someone else is currently editing on a network share. What does AutoCAD normally do?

Answer: Opens it read-only

Because of the lock file, AutoCAD tells the second user the file is in use and offers to open it read-only.
