PDFs have evolved from static pages to complex documents with features such as interactive forms, multimedia content, scripting, and other capabilities. These features leave PDFs vulnerable to malicious scripts or actions that can damage the computer or steal data. The Enhanced security feature protects the computer against these threats by blocking or selectively permitting actions for trusted locations and files. Enhanced Security determines if a PDF is viewed within a standalone application. A threat to users of Adobe Reader DC is opening a PDF file that contains malicious executable content. Enhanced Security “hardens” the application against risky actions: prevents cross domain access, prohibits script and data injection, blocks stream access to XObjects, silent printing, and execution of high privilege JavaScript.

Clicking any link to the Internet poses a potential security risk. Malicious websites can transfer harmful content or silently gather data. Acrobat Reader documents can connect to websites which can pose a potential threat to DoD systems and that functionality must be blocked. However, PDF document workflows that are trusted (e.g., DoD-created) can benefit from leveraging legitimate website access with minimal risk. Therefore, the ISSO may approve of website access and accept the risk if the access provides benefit and is a trusted site or the risk associated with accessing the site has been mitigated. Adobe Reader must block access to all websites that are not specifically allowed by ISSO risk acceptance. Satisfies: SRG-APP-000112, SRG-APP-000206, SRG-APP-000207, SRG-APP-000209, SRG-APP-000210
