Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block] | Risk Management and Strategy We have developed and continue to enhance our cybersecurity governance program to help protect the security of our computer systems, software, networks, and other technology assets against material risks from cybersecurity threats, including unauthorized attempts to access confidential information or to disrupt or degrade our business operations. Our cybersecurity governance program is strategically integrated into our broader risk management framework and aims to (1) proactively manage cyber and information security risks at AutoNation, (2) implement the internal controls required by cybersecurity regulatory requirements as well as AutoNation’s information security control objective documents and information security standards, and (3) improve the efficiency, maturity, and effectiveness of technology functions and processes. We regularly evaluate new and emerging risks and ever-changing legal and compliance requirements and examine the effectiveness and maturity of our cyber defenses through various means, including internal audits, targeted testing, incident response exercises, maturity assessments, and industry benchmarking. We also dedicate significant resources that are designed to secure our systems and to protect confidential information, such as firewalls, endpoint protection, and behavior analysis tools, among others, and engage with a range of external experts, including cybersecurity assessors, consultants, and auditors in evaluating and testing our risk management systems. In addition, we annually perform a risk assessment of our third-party service providers.
