Cybersecurity Risk Management, Strategy, and Governance [Line Items] |
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block] | Item 1C. Cybersecurity. Risk Management and Strategy We have implemented systems and processes intended to secure our information technology systems and prevent unauthorized access to or loss of sensitive, confidential and personal data. These processes are implemented and overseen primarily by our Chief Information Officer (CIO) and Chief Information Security Officer (CISO). Our CIO has over 35 years of experience and in his 20 years at NVR has been responsible for the implementation and modernization of many of our key technologies across the enterprise. Our CISO has over 25 years of experience in information technology architecture, including over 18 years with NVR in progressively more senior information security roles. Significant information technology processes that have been implemented include: - vulnerability management to help ensure security updates are effectively applied, - utilization of encryption and multi-factor authentication technologies to protect company data, - regular required training for all employees with systems access regarding matters such as cybersecurity threats and data protection, and utilization of simulated phishing tests to increase security awareness, - regular review of third-party service providers, including review of their system and organization controls (SOC) reports, - enhanced monitoring capabilities for early detection and rapid response to potential security anomalies, - documented incident response readiness process updated annually, - completion of tabletop exercises on potential cybersecurity breaches with the assistance of a third-party cybersecurity consultant, and - regular review of information technology disaster recovery and business continuity processes to help ensure the ability to resume work after an incident. Review of these processes has been incorporated into our annual risk assessment and internal audits of controls performed by our Internal Audit department. Results of these audits are reported to the Audit Committee by our Vice President of Internal Audit and Corporate Governance. As previously discussed in Item 1A of this Form 10-K "Risk Factors", failure to maintain the security of the data we are required to protect could have a material adverse effect on our operations and financial results. We currently do not believe that any current cybersecurity threats have materially affected, or are reasonably likely to materially affect, our business strategy, results of operations or financial condition.
