Enhanced Security (ES) is a sandbox capability that restricts access to system resources. ES can be configured in two modes: Standalone mode is when Acrobat opens the desktop PDF client. ES Browser mode is when a PDF is opened via the browser plugin. When Enhanced Security is enabled and a PDF file tries to complete a restricted action from an untrusted location, a security warning must appear. Enhanced Security “hardens” the application against risky actions. It prevents cross domain access, prohibits script and data injection, blocks stream access to XObjects, silent printing, and execution of high privilege JavaScript.

Protected View is a “super-sandbox” that is essentially a read-only mode. When enabled, Acrobat strictly confines the execution environment of untrusted PDF's and the processes the PDF may invoke. Acrobat also assumes all PDFs are potentially malicious and confines processing to a restricted sandbox. When the PDF is opened, the user is presented with the option to trust the document. When the user chooses to trust the document, all features are enabled, this action assigns trust to the document and adds the document to the users’ list of Privileged Locations.

Security flaws with software applications are discovered daily. Vendors are constantly updating and patching their products to address newly discovered security vulnerabilities. Organizations (including any contractor to the organization) are required to promptly install security-relevant software updates (e.g., patches, service packs, and hot fixes). Flaws discovered during security assessments, continuous monitoring, incident response activities, or information system error handling must also be addressed expeditiously. This requirement will apply to software patch management solutions that are used to install patches across the enclave and also to applications that are not part of that patch management solution. For example, many browsers today provide the capability to install their own patch software. Patch criticality, as well as system criticality, will vary. Therefore, the tactical situations regarding the patch management process will also vary. This means that the time period used must be a configurable parameter. Time frames for application of security-relevant software updates may be dependent upon the Information Assurance Vulnerability Management (IAVM) process. The application will be configured to check for and install security-relevant software updates within an identified time period from the availability of the update. The specific time period will be defined by an authoritative source (e.g., IAVM, CTOs, DTMs, and STIGs).

Acrobat Pro XI provides a Webmail capability. This allows users to send PDFs as email attachments using any mail account that supports SMTP/IMAP protocols. In addition to existing desktop email clients, users can now configure these mail accounts by providing User Name, Password, IMAP and SMTP details. The capability allows users to utilize Gmail and Yahoo mail accounts to send PDF files directly from within the Acrobat application. This capability allows the user to by-pass existing email protections provided by DoD email services.
