Border Logic
Border Logic: “Software, firmware, or HARDWIRED LOGIC that is developed to connect APPLICATION LOGIC to COTS or THIRD-PARTY LOGIC.
Definition
“Software, firmware, or HARDWIRED LOGIC that is developed to connect APPLICATION LOGIC to COTS or THIRD-PARTY LOGIC. … Although it is typically developed by the voting system manufacturer, border logic is constrained by the requirements of the third-party or COTS interface with which it must interact. It is not always possible for border logic to achieve its function while conforming to standard coding conventions. For this reason, border logic should be minimized relative to application logic and where possible, wrapped in a conforming interface. An example of border logic that c ould not be so wrapped is a customized boot manager that connects a bootable voting application to a COTS BIOS.” 2007 VVSG.
