Busey’s cyber security risk management program is a key part of the Company’s overall risk management system, which is administered by the Chief Risk Officer. Busey’s cyber security risk management program includes administrative, technical, and physical safeguards to help ensure the security and confidentiality of customer records and information. Busey has long devoted significant resources to assessing, identifying, and managing risks associated with cybersecurity threats, including: •Establishing an internal cybersecurity team that is responsible for conducting regular assessments of Busey’s information systems, existing controls, vulnerabilities, and potential improvements; •Employing continuous monitoring tools that can detect and help respond to cybersecurity threats in real-time; •Performing due diligence with respect to third-party service providers, including their cybersecurity practices, and requiring contractual commitments from Busey’s service providers to take certain cybersecurity measures; •Ongoing monitoring and assessment of third-party vendors' cybersecurity practices, including regular audits, compliance checks, and incident reporting requirements; •Engaging third-party cybersecurity consultants, who conduct periodic penetration testing, vulnerability assessments, and other procedures to identify potential weaknesses in Busey’s systems and processes; •Mandating periodic cybersecurity training for Busey’s workforce, which includes awareness programs on phishing, social engineering, and other common cyber threats; •Implementing access control measures such as multi-factor authentication, role-based access controls, and regular access reviews to ensure that only authorized personnel have access to critical systems and data; •Using data encryption for both data at rest and data in transit to protect sensitive information; and •Creating an incident response plan that outlines the steps to contain, mitigate, and remediate the impact of cybersecurity incidents, including communication protocols and post-incident analysis. Busey’s security and privacy policies and procedures are in effect across all of its businesses and geographic locations. Busey adheres to various regulatory requirements and standards, including the Gramm-Leach-Bliley Act to ensure compliance with data protection laws.
