SLI Compliance provides independent verification and validation of voting systems to ensure only proper versions of the software and no unauthorized software is present that could exploit any vulnerabilities. We sample hash codes from the Trusted Build and perform validation tests on the system onsite.

Our team conducts system audits and tests to ensure that the deployed system is identical to the certified baseline and that no improper data entry or security penetration occurred that would affect count accuracy.

We conduct audits to ensure security techniques being used are valid and that effective security procedures are contained in the design.  Security features are compared for validity against NIST Special Publications and ANSI Standards and Guidelines. We ensure that techniques being used are effective as built and can recommend enhanced techniques that should be implemented where needed. Overall, the end-to-end security process is reviewed to identify any weakness in the security chain.

The SLI Compliance team pays particular attention to any aspects of the overall design that could place the system at risk. We use FIPS Compliant hashing algorithms to provide independent verification and validation to confirm the software and data have not been modified in any manner from the originally test baseline. Finally, where risks are identified, we itemize corrective actions and compensating controls, including system configurations and architecture that can mitigate risks.




Election Auditing

  • I want to thank you again for SLI's independent assessment of Broomfield's election procedures and subsequent development of updated election procedures. SLI's work assisted the City Council greatly in understanding the strengths and weaknesses of existing systems and helped restore confidence in these systems for future elections.

  • It is with sincere gratitude and appreciation that we unconditionally recommend SLI. Our effort to obtain Meaningful Use Stage 2 Certification for our community health software platform required significant interpretation of the federal guidelines that SLI provided in plain English, on an as needed, and always timely basis. The staff is outstanding and their attitude is nothing less than grace under pressure. To keep it all together, with client after client struggling to interpret often vague federal guidelines, is laudable. The bottom line is that we had a choice, and we went with a recommendation for SLI based on a couple interviews with folks that preceded us, and it turned out to be the best possible decision.

  • I sought SLI’s assistance in providing information to me on testing practices for the Uniform Voting System (UVS) that the State of Colorado is seeking. I also worked with them as they developed a report for the Colorado Voter Access and Modernized Elections Commission on an assessment of voting system technology in Colorado. The results provided by SLI were valuable and helped the state make key decisions regarding Colorado's UVS strategy. As our project moves forward, we expect to call upon SLI to test one or more proposed systems to meet Colorado Voting System Certification Standards.

  • The SLI team, in my opinion, was outstanding. I truly appreciated this process and all the guidance they provided. Not only did this team well represent themselves and the expertise they possess, but also well represented the SLI organization. I would highly recommend SLI to anyone...

  • We are so gratified that our cumulative efforts have yielded the much-needed results. I must hasten to add that the work of the entire SLI team has lent so much credibility to this entire electoral process. For this alone, you have the gratitude of not just this member of the Technical Evaluation Committee, but more likely that of an entire nation.
