Security Fundamentals Flashcards

A CAD manager wants AutoCAD to load executable files ONLY from trusted locations and silently block everything else. Which SECURELOAD value should be set?

Answer: 2

SECURELOAD set to 2 restricts loading to trusted locations and blocks executables from any other folder without prompting.

Which system variable stores the list of folders AutoCAD treats as trusted for loading executable code?

Answer: TRUSTEDPATHS

TRUSTEDPATHS holds the trusted folder locations used by SECURELOAD to decide which executables may load without warning.

When adding a trusted location, what suffix makes AutoCAD also trust all subfolders of that path?

Answer: \...

Ending a trusted path with \... extends trust to every subfolder beneath it.

Why does Autodesk recommend that trusted locations be set as read-only for regular users?

Answer: To prevent malicious or accidental code from being placed in a folder AutoCAD loads without warning

If users or malware can write to a trusted folder, any file dropped there would load without a security prompt.

Which file is automatically loaded into every drawing opened in AutoCAD and has historically been a target for AutoLISP viruses?

Answer: acaddoc.lsp

acaddoc.lsp loads with every drawing, so malicious copies placed alongside drawings were a common infection vector.

With SECURELOAD set to 1 (the default), what happens when a user tries to load an LSP file from a folder that is not trusted?

Answer: A security warning asks the user whether to load it

At the default value of 1, AutoCAD shows a security concern dialog for executables outside trusted locations.

Which AutoCAD startup switch launches the program without loading any executable code such as LSP, ARX, or VBA files?

Answer: /safemode

The /safemode switch disables the loading of executable files for that session, which helps when troubleshooting suspected malicious code.
