Description
Acrobat Pro allows for files to be attached to PDF documents. Attachments represent a potential security risk because they can contain malicious content, open other dangerous files, or launch applications.This feature prevents users from opening or launching file types other than PDF or FDF and disables the menu option to re-enable.

Who does this work

5 NICE work roles and 5 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.
