Here is How the U.S. Government Wants You to Talk About Election Cybersecurity

In a September 2018 report, the office of the Director of National Intelligence provide a common lexicon and set of definitions for how cybersecurity professionals should be talking about election security issues.

According to the document “This reference aid draws on CTIIC’s experience promoting interagency situational awareness and information sharing during previous significant cyber events—including cyber threats to elections. It provides a guide to cyber threat terms and related terminology issues likely to arise when describing cyber activity. The document includes a range of cyber-specific terms that may be required to accurately convey intelligence on a cyber threat event and terms that have been established by relevant authorities regarding technical infrastructure for conducting elections.”

Adopting these terms within your own cyber intelligence practice will help streamline communications on the issue with the U.S. government, industry peers, and cybersecurity vendors.

Describing What’s Happened: Common Terms
The following terms are central to accurately describing cyber threat activity but are often used differently. CTIIC recommends their use be accompanied by definitions and any necessary context for nontechnical readers.

Attacked
Indicates that a cyber actor has attempted to degrade, destroy, disrupt, manipulate, or otherwise detrimentally affect the operation of a system or network. However, manipulation or deletion of data solely for the purpose of hiding one’s tracks is not considered an attack. Some reports use “attack” and “exploit” synonymously, drawing in part on the cryptanalysis sense of “attack”—the use of a technical approach to defeat a security measure. The dual usage can cause confusion, especially for nontechnical readers, if the context does not fully explain the type of malicious cyber activity that occurred.

Compromised
Indicates that a victim system has installed malware, connected to a malicious Internet victim tor’s Protocol address, or provided a cyber actor unauthorized access to collect data or execute commands.

Exploited
Indicates that a malicious actor has conducted additional activities on a compromised system, such as collecting data, deploying more malware, or establishing persistent access. Some documents—within both the IC and the private sector—use exploited and compromised synonymously. In practice, however, cyber actors may compromise more accounts and systems than they exploit, in part because of the availability of tools to automate the process of compromising vulnerable systems. Distinguishing whether and how an actor has made use of a compromised system—whenever available intelligence allows—aids in understanding the impact and implications of the malicious cyber activity.

Scanned/Scanning
Scanning a system involves attempting to identify the security vulnerabilities the system may have by sending it specific network traffic and observing its responses. The definition is reasonably specific but can cause confusion—and potentially undue alarm—if it is assumed to include follow-on attempts to exploit any vulnerabilities discovered. Scanning is extremely common on the Internet but may have only a modest success rate, and cyber actors therefore scan far more systems than they actually affect.

Targeted/Targeting
A cyber actor’s targeting of a particular victim can refer to any aspect of the actor’s attempts to select a system to conduct operations against, learn about, find vulnerabilities, gain access, or conduct other malicious activities. The term also connotes an attempt at conducting malicious cyber activity, without indicating the degree of success an actor achieved. We recommend greater specificity and clarification of the specific usage whenever available intelligence allows.

Election-Specific Terms
These terms have been defined by the US Election Assistance Commission (EAC), a bipartisan commission charged with developing voting system guidelines.

Audit
Systematic, independent, documented process for obtaining records, statements of fact, or other relevant information and assessing them objectively to determine the extent to which specified requirements are fulfilled.

Ballot
The official presentation of all of the contests to be decided in a particular election.

Central Count Voting System
A voting system that tabulates ballots from multiple precincts at a central location. Voted ballots are placed into secure storage at the polling place. Stored ballots are transported or transmitted to a central counting place, which produces the vote count report.

Claim of Conformance
Statement by a vendor declaring that a specific product conforms to a particular standard or set of standard profiles; for voting systems, National Association of State Election Directors (NASED) qualification or EAC certification provides independent verification of a claim.

Direct Recording Electronic (DRE) Voting System
System that uses electronic components for the functions of ballot presentation, vote capture, vote recording, and tabulation that are logically and physically integrated into a single unit. A DRE produces a tabulation of the voting data stored in a removable memory component and in printed hardcopy.

Election Databases
Data file or set of files that contain geographic information about political subdivisions and boundaries, all contests and questions to be included in an election, and the candidates for each contest.

Electronic Voting System
One or more integrated devices that use an electronic component for one or more of the following functions: ballot presentation, vote capture, vote recording, and tabulation.

Independent Testing Authority (ITA)
Replaced by “accredited testing laboratories” and “test labs.” Previous usage referred to independent testing organizations accredited by NASED to test voting system qualifications.

Internal Audit Log
A human-readable record, residing on the voting machine, used to track all activities of that machine. This log records every activity performed on or by the machine, indicating the event and when it happened.

Precinct Count Voting System
A system that tabulates ballots at the polling place, typically as they are cast, and prints the results after the close of polling. For DREs, and for some paper-based systems, these systems electronically store the vote count and may transmit results to a central location over public telecommunication networks.

Security Analysis
An inquiry into the potential existence of security flaws in a voting system. Includes an analysis of the system’s software, firmware, and hardware, as well as the procedures associated with system development, deployment, operation, and management.

Security Controls
Management, operational, and technical controls (i.e., safeguards or countermeasures) prescribed for an information system to protect the confidentiality, integrity, and availability of the system and its information.

Voting System
The total combination of mechanical, electromechanical, or electronic equipment (including the software, firmware, and documentation required to program, control, and support
the equipment) that is used to define ballots; to cast and count votes; to report or display election results; and to maintain and produce any audit trail information; and the practices and associated documentation used to identify system components and versions of such components; to test the system during its development and maintenance; to maintain records of system errors and defects; to determine specific system changes to be made to a system after the initial qualification of the system; and to make available any materials to the voter (such as notices, instructions, forms, or paper ballots).

The following terms, which reflect the changing technology used at election polling stations, have been defined by organizations other than the EAC.

Ballot on Demand (BOD)
A dedicated application that prints out a dedicated ballot as each voter checks in. BODs may also be used by polling stations to print additional ballots in emergency situations.

Election Management System
Set of processing functions and databases within a voting system that defines, develops, and maintains election databases; performs election definitions and setup functions; formats ballots; counts votes; consolidates and reports results; and maintains audit trails.
