Dod Mobile Code Risk Categories [RELIABLE · 2027]

The Department of Defense (DoD) categorizes —software like JavaScript or ActiveX that downloads and executes automatically—based on its functionality and the potential threat it poses to information systems. These risk categories help determine which technologies are safe for use on government workstations and remote servers.

: Most Java applets fall into this category. They are designed to be restricted from reaching the underlying system unless specific vulnerabilities (sandbox escapes) are exploited.

While the primary policy governing these categories is , the specific risk tiers are structured by the level of access the code has to system resources. The Three Mobile Code Risk Categories Dod Mobile Code Risk Categories

: Code with limited access to system resources, typically operating within a controlled containment model or "sandbox".

: Technologies that support limited functionality with no capability for unmediated access to system resources. The Department of Defense (DoD) categorizes —software like

: Use of this category is strictly controlled and often prohibited unless the code is signed by a trusted US certificate signing authority. Category 2: Limited Access (Medium Risk)

: Flaws in the containment models of Category 2 code can allow it to reach sensitive data it should not see. They are designed to be restricted from reaching

: Historically, this included ActiveX and Shockwave Flash , which could operate outside a restricted "sandbox" environment to interact directly with the operating system.
