Security you can count on.®
Physical and system access controls
- The central count tabulators (DS450, DS850 and DS950) use keylocks and security seals to protect against tampering or intervention in system operations.
- All data ports and the power switch are secured behind clear plastic lockable and sealable doors to protect access and allow election officials to easily detect unauthorized access
System application controls
- These tabulators cannot write or otherwise change the election program once installed. The central count election media content is digitally signed and verifiable using the application.
- No options to change any ballot information exist on the central count tabulators.
- All administrative functions are limited to the controls allowed through the touch-screen interface for machine operation only.
Encryption, hash validation and digital signatures
- The units use digital encryption and signing of key configuration and data files for complete integrity of the election and results. All central count data is signed with FIPS-compliant digital signature algorithms. All generated data is also signed so that the program receiving the data can validate it.
Audit logs
- The tabulators generate a digitally signed audit log that tracks all events that occur on the unit — whether successful or failed — such as passcode attempts, user actions, system events and error messages.
- The tabulators provide options for printed and electronic real-time logs of all activity performed, allowing users to reprint logs on-demand or export electronic logs for review.
- Only the system can create, read, modify and delete the audit log content because the user interface is locked out of these functionalities.
