Election systems are essential public infrastructure, supporting the secure administration of voting and the public’s confidence in democratic outcomes. As these systems become more connected, election infrastructure protection has emerged as a national security priority, requiring safeguards against cyberattacks, physical disruption, and failures that could undermine reliable operations.
Protecting election infrastructure involves more than securing voting machines. It also means safeguarding voter registration databases, election offices, communications networks, equipment, and supply chains. Effective security combines risk-based protections with resilient backup plans, coordination among responsible agencies, and transparent processes that help ensure results can be independently verified.
Why Election Infrastructure Protection Is a National Security Priority
Election infrastructure underpins the democratic process and the lawful transfer of political power. Disruption or unauthorized access could interfere with election administration, expose sensitive information, or delay the reporting of results, with consequences for public trust and government continuity.
The risks extend beyond voting machines. Systems used to register voters, manage election operations, communicate with officials, and report results may be targets of cyber activity, physical attacks, or attempts to spread false information. Protecting these interconnected functions is therefore part of safeguarding national security.
Election Infrastructure Protection also supports resilience against accidental failures and natural hazards. Prepared systems and clear procedures can help election officials maintain operations, verify results, and recover from disruptions without compromising the integrity of the process.
Because elections are administered across jurisdictions, security depends on coordination among local, state, and federal authorities, as well as relevant private-sector partners. This shared responsibility helps address threats while preserving the decentralized structure of U.S. elections.
Core Components of Election Infrastructure
Election infrastructure encompasses the people, systems, facilities, and processes that support voting and the administration of elections. Its components extend beyond voting machines: voter registration databases, election management systems, polling locations, communications networks, and systems used to report results are all part of the wider environment.
Voter registration databases store records used to determine voter eligibility and maintain registration information. Election management systems help officials prepare ballots, manage election tasks, and organize results. Because these systems handle sensitive data and operational information, their accuracy and availability matter throughout the election cycle.
Voting devices, ballot scanners, and tabulation systems support the casting and counting of votes. Their functions vary by jurisdiction, and some processes rely on paper ballots that can provide a record for audits or recounts. Clear procedures help officials verify that equipment is configured and used as intended.
Election offices, communications channels, and supporting networks connect staff, equipment, and public services. Protecting election infrastructure therefore requires understanding how these components interact, including dependencies on third-party technology and essential services.
Voter registration databases and election management systems
Voter registration databases hold records used to determine voter eligibility and maintain accurate voter rolls. Election management systems support administrative tasks such as preparing ballots, assigning polling locations, and tracking election operations. Together, these systems handle sensitive information and influence important stages of the voting process.
Their security depends on protecting the confidentiality, integrity, and availability of data. Unauthorized access or improper changes could expose personal information or disrupt election administration. Strong access controls, multifactor authentication, activity logging, and timely software updates help reduce these risks.
Election officials should also maintain accurate records through authorized procedures for adding, updating, or removing voter information. Clear separation of duties and reviewable audit trails can help detect errors and support accountability. These safeguards are practical elements of election infrastructure protection.
Because systems and procedures differ by jurisdiction, protections should reflect local requirements and technology. Documented backups and tested recovery plans can help officials restore access to reliable records if a system is disrupted, while preserving established controls for data changes.
Voting devices, ballot scanners, and tabulation systems
Voting devices capture voter selections, while ballot scanners interpret marked paper ballots and tabulation systems count votes. These components may be separate or integrated, depending on the jurisdiction’s equipment. Because they directly handle or process votes, their security and reliable operation are central to election infrastructure protection.
Safeguards include restricting physical and digital access, maintaining documented custody of equipment, and using approved, securely configured software. Election officials should verify equipment before use and retain records of testing, maintenance, and any authorized changes. Specific procedures vary by jurisdiction and system.
Paper records can support independent checks of electronic counts. Where voter-marked paper ballots are available, risk-limiting audits or other established post-election audits can compare samples of ballots with reported results. These checks help detect discrepancies without assuming that any technology is error-free.
If a device fails, officials need procedures to preserve ballots and continue voting or counting in accordance with applicable law. Clear documentation and tested contingency processes help protect the integrity of results while limiting disruption.
Election offices, communications, and supporting networks
Election offices depend on more than voting equipment. Their day-to-day work uses email, phone systems, internal networks, and software for scheduling, logistics, and coordination. Disruptions to these services can delay operations or hinder communication with staff, local authorities, and the public.
Supporting networks may connect election offices with state agencies, vendors, and other partners. Each connection can introduce security risks, particularly when accounts are compromised or systems are misconfigured. Limiting access to authorized users and monitoring network activity can help reduce exposure.
Communications also need reliable backup methods. Election offices can maintain current contact lists and establish procedures for sharing verified updates if primary email, phone, or internet services become unavailable. These measures support continuity without relying on a single channel.
As part of Election infrastructure protection, offices should define who can access systems, how incidents are reported, and which services must be restored first. Regular staff training and tested continuity procedures help teams respond consistently to technical disruptions and suspected cyber incidents.
Identifying Threats to Election Infrastructure
Threats to election infrastructure can target digital systems, physical assets, or the people and processes that support them. They may involve state or criminal actors, insiders, or accidental errors; attribution is not always possible from initial evidence.
Common threat categories include:
- Cyberattacks, such as phishing, ransomware, denial-of-service attacks, and attempts to access or alter data.
- Physical interference with election offices, equipment, or communications links.
- Supply-chain risks, including compromised software, hardware, or service providers.
- Misinformation that falsely claims systems are compromised or results have been manipulated.
Threats can affect voter registration, election management, voting, or the reporting of results. Identifying them requires monitoring credible indicators—such as unusual account activity, unexpected system changes, or equipment tampering—while distinguishing verified incidents from unsubstantiated claims.
Election officials should document reports and coordinate with relevant technical and law-enforcement partners. A clear picture of likely threats helps guide later risk assessments and protection priorities.
Assessing Risk and Setting Protection Priorities
Risk assessment helps election officials determine which assets and services face the greatest threats and what consequences a disruption could cause. The process should consider the likelihood of incidents, potential effects on voting and tabulation, and the time required to restore operations.
Officials can map critical systems, dependencies, and access points, then evaluate risks such as unauthorized access, malware, equipment failure, physical damage, or service outages. Assessments should reflect local conditions, including staffing, facility security, network design, and reliance on outside vendors.
Protection priorities should be based on risk, not convenience alone. Systems supporting voter registration, ballot preparation, vote capture, and result reporting may warrant stronger safeguards, while practical plans should also address limited budgets and personnel. Election infrastructure protection requires regular reviews because systems, threats, and operational needs change.
Documenting decisions makes it easier to assign responsibilities, direct resources, and explain why particular safeguards were selected. Officials should revisit priorities after significant system changes, identified vulnerabilities, or incidents, while coordinating with relevant state and federal partners when appropriate.
Securing Election Systems and Networks
Election infrastructure protection depends on safeguarding the systems that support voter registration, election management, and vote processing. Security measures should reflect each system’s function and potential impact, while preserving availability and ensuring that authorized election personnel can complete their work.
Access controls limit who can view or change sensitive data. Multifactor authentication can strengthen account security, and least-privilege permissions give users only the access needed for their duties. Election offices should also review accounts regularly and remove access when roles change.
Network segmentation can help contain an intrusion by separating critical systems from less sensitive networks. Timely patching and secure configurations reduce exposure to known weaknesses, though updates should be tested before deployment to avoid disrupting election operations.
A disciplined security program should include:
- Independent testing of systems and configurations
- Ongoing vulnerability tracking and remediation
- Monitoring for unusual activity, with procedures for reporting and responding to incidents
These controls support secure operations without treating any single measure as a substitute for layered defenses.
Access controls, multifactor authentication, and least privilege
Access controls determine who may enter election systems and what actions each account can perform. Election officials should assign individual accounts rather than shared credentials, making activity traceable and access easier to revoke when personnel change roles or leave.
Multifactor authentication adds verification beyond a password, such as a hardware security key or an authenticator app. Applying it to remote access, administrative accounts, and other sensitive systems can reduce the risk that a stolen password alone will enable intrusion.
The principle of least privilege limits each user to the information and functions needed for assigned duties. For example, staff responsible for voter registration should not automatically receive administrative rights to voting equipment or election-management systems.
These safeguards should cover employees, temporary workers, and authorized vendors, with permissions reviewed regularly and removed promptly when no longer required. As part of election infrastructure protection, clearly documented access procedures support accountability without disrupting legitimate election work.
Network segmentation, patching, and secure configurations
Network segmentation limits how far an intruder can move if one system is compromised. Election offices can separate voter registration databases, election management systems, voting equipment, and public-facing services into distinct network zones. Connections between zones should be restricted to those required for legitimate operations.
Patching addresses known software vulnerabilities, but updates must be planned around election schedules and tested for compatibility before deployment. Election officials should track software versions, prioritize urgent security fixes, and coordinate with vendors when systems are managed or supported externally.
Secure configurations reduce unnecessary exposure. Disable unused services and accounts, change default credentials, apply approved security settings, and restrict administrative access. Documenting configurations helps teams detect unauthorized changes and restore systems consistently.
Together, these practices support election infrastructure protection by reducing attack paths and limiting the impact of a breach. Controls should be reviewed regularly, since system changes, newly disclosed vulnerabilities, and operational requirements can alter the risks.
Independent testing and vulnerability management
Independent testing provides an objective assessment of election systems beyond routine internal checks. Qualified testers can examine software, configurations, and network defenses for weaknesses, using methods approved by election officials and designed to avoid disrupting live operations or exposing sensitive data.
Vulnerability management turns findings into tracked corrective actions. Election officials should assess each issue’s severity, potential impact on election services, and available mitigations, then document remediation and retesting. Testing should be authorized, scoped, and coordinated with system vendors where necessary.
A practical process can include:
- Reviewing independent assessment reports and security advisories.
- Prioritizing vulnerabilities based on risk and operational context.
- Applying verified updates or compensating controls, then retesting.
- Recording unresolved issues, decisions, and responsible personnel.
For election infrastructure protection, testing must complement—not replace—certification requirements, operational safeguards, and established procedures. Reports should be shared only with authorized parties when they contain sensitive technical details, while officials communicate relevant security practices transparently to the public.
Protecting Election Facilities, Equipment, and Supply Chains
Election offices and storage sites should use controlled entry, visitor logs, secure keys or badges, and alarms where appropriate. Limit access to authorized personnel, and store ballots, voting devices, and other sensitive materials in locked, monitored areas with documented handling procedures.
Equipment should be inventoried, labeled, and tracked as it moves between facilities. Before and after use, officials can inspect devices for tampering, verify seals, and record maintenance. Clear custody records help identify discrepancies and support investigations without disrupting routine election operations.
Supply-chain safeguards extend to purchasing, delivery, repair, and disposal. Election officials should assess vendors, confirm that equipment comes from authorized sources, and require secure handling of devices and components. Unneeded media and equipment should be sanitized or destroyed using approved procedures.
These physical controls complement cybersecurity measures in election infrastructure protection. Facility access plans should also address disruptions such as power loss, fire, or severe weather, so staff can secure equipment and maintain orderly operations under established contingency procedures.
Building Resilience Through Backups and Contingency Planning
Election offices should maintain secure, tested backups of voter registration data, election management files, and other records needed to administer elections. Backups should be protected from unauthorized access and ransomware, stored separately from primary systems, and checked regularly to confirm that data can be restored accurately.
Recovery procedures should identify who can authorize restoration, which systems take priority, and how records will be verified before use. Documented steps help election officials respond in a controlled manner if equipment fails, data is corrupted, or a cyber incident disrupts operations.
Contingency plans should also cover practical alternatives, such as backup power, replacement equipment, paper-based processes, and alternate communications. These options must comply with applicable law and preserve ballot security, accessibility, and accurate recordkeeping.
Election infrastructure protection depends on plans that work under real conditions. Exercises involving election staff and relevant partners can reveal gaps, clarify responsibilities, and improve response and continuity procedures before an actual disruption occurs.
Maintaining secure backups and recovery procedures
Election offices should create backups of voter registration data, election management configurations, and other records needed to conduct and certify elections. Copies should be protected from unauthorized access, alteration, and ransomware, with encryption and tightly controlled permissions where appropriate.
A backup is useful only if it can be restored. Election officials should document recovery steps, assign responsible personnel, and test restoration regularly in a controlled environment. Tests can reveal corrupted files, outdated procedures, or dependencies that could delay recovery.
At least one backup should be separated from the systems it protects, such as through offline or otherwise isolated storage. This reduces the risk that a cyber incident affecting operational networks will also compromise recovery copies.
Recovery procedures should identify which systems and data take priority, how their integrity will be checked, and how restored information will be reconciled with authoritative records. These measures support election infrastructure protection while helping officials resume operations accurately after disruption.
Preparing alternative processes for disruptions
Election officials should define lawful fallback procedures for disruptions such as equipment failure, network outages, severe weather, or loss of access to a polling location. Plans should specify who can authorize each measure, how voters will be informed, and how ballot security and chain of custody will be maintained.
Depending on applicable law and local procedures, alternatives may include:
- Using approved paper ballots when voting equipment is unavailable.
- Directing voters to another accessible site or providing other authorized ways to vote.
- Recording and securely reconciling ballots when electronic reporting systems are offline.
Alternative processes should be documented, accessible to voters with disabilities, and consistent with election laws. Staff need clear instructions and training so a disruption does not lead to improvised or inconsistent practices.
Regular exercises can test whether personnel can carry out these procedures and account for ballots under pressure. As part of election infrastructure protection, fallback plans should also identify secure communications methods and the steps for restoring normal operations.
Testing incident response and continuity plans
Election officials should rehearse how they would detect, report, contain, and recover from incidents such as ransomware, equipment failure, or loss of communications. Exercises can use realistic scenarios without connecting test activity to live voting systems or exposing sensitive information.
Tabletop exercises allow staff, technical teams, and agency partners to walk through decisions and responsibilities. Functional drills can test specific capabilities, such as restoring a system from a backup or switching to an alternative communication method. Each exercise should have clear objectives and documented results.
Continuity plans should be tested against practical constraints, including staff availability, access to facilities, and time needed to restore essential services. Exercises should also verify that escalation paths and contact lists are current, and that participants understand who has authority to make operational decisions.
After each test, officials should record gaps, assign corrective actions, and set deadlines for addressing them. Retesting those changes helps confirm that procedures work as intended and strengthens election infrastructure protection without disrupting election operations.
Coordinating Election Security Across Agencies and Partners
Election security depends on clear coordination among local election officials, state authorities, and relevant federal agencies. Defined points of contact and established procedures help partners share timely, actionable information while preserving each jurisdiction’s authority over election administration.
Election offices can coordinate with cybersecurity agencies, law enforcement, emergency managers, and providers of election systems and communications. Each partner should understand its responsibilities, reporting channels, and limits on information sharing, including safeguards for sensitive operational details.
Joint planning supports faster responses to suspected intrusions, equipment failures, or threats to election facilities. Exercises can clarify who assesses an incident, who communicates with affected officials, and how technical assistance is requested. These arrangements strengthen election infrastructure protection without disrupting routine operations.
Coordination should continue beyond active incidents. Regular briefings, trusted reporting channels, and lessons-learned reviews help partners address emerging risks and improve preparedness. Clear, consistent public communication can also reduce confusion while protecting investigative information and the integrity of ongoing election processes.
Strengthening Public Confidence Through Verifiable Results and Transparency
Public confidence depends on evidence that election results were produced and counted accurately. Election infrastructure protection supports this confidence, but security measures should also be paired with clear procedures for verifying outcomes and explaining them to the public.
Risk-limiting audits, conducted according to state law and established procedures, can check a sample of paper ballots against reported results. Their findings provide an independent check on tabulation and may trigger a broader review when discrepancies exceed defined limits.
Election officials can publish audit methods, schedules, results, and explanations of any corrections in accessible language. Transparency should protect sensitive information, such as voter data and system credentials, while giving observers and the public meaningful ways to understand the process.
Consistent communication before and after an election helps distinguish verified facts from unsubstantiated claims. Promptly documenting incidents, describing their impact accurately, and explaining how they were addressed can reinforce accountability without overstating what security controls can guarantee.
