Cybersecurity Risk Management, Strategy, and Governance [Line Items] |
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block] | RISK MANAGEMENT AND STRATEGY MGIC’s Information Security Program (ISP) includes information security policies, annual risk assessments and analyses, threat monitoring and alerting, vulnerability management, incident response, and data loss prevention controls. With the ISP, MGIC seeks to prevent, detect, and respond to unauthorized access, use, or disclosure of confidential information. MGIC’s Information Risk Management (IRM) team is responsible for safeguarding the organization's information assets, data, and technology infrastructure from security threats and vulnerabilities. The IRM team’s primary focus is the protection of the confidentiality, integrity, and availability of sensitive information and compliance with relevant laws, regulations, and industry standards. The IRM team is overseen by the Company's Chief Information Security Officer (CISO). Our ISP is benchmarked against the National Institute of Standards and Technology (NIST) Cybersecurity Framework. Additionally, various aspects of the ISP are subject to periodic audit by the Company’s Internal Audit department or third-party professionals engaged by the Internal Audit department. Such audits vary from year-to-year but are generally focused on compliance with stated control activities, standards, and internal policies, as well as maintaining the integrity and independence of the audit process. Cybersecurity risk reviews such as SOC2, SOX controls, penetration tests, and regulatory controls are conducted by independent third parties. The ISP also incorporates a vendor due diligence process that is designed to assess vendor control environments and evaluate risks associated with vendor access to the Company's confidential data and systems. The process includes assessing and managing the cyber risks associated with engaging third-party vendors and reviewing their information security practices. In the event of a suspected or threatened cybersecurity incident, the CISO determines whether to activate the Company’s Cyber Incident Response Team (“CIRT”), composed of different subject matter experts from applicable domains such as network, infrastructure, and application areas in order to evaluate the technical issues relative to the incident. The CIRT is overseen by the CISO. If necessary, the CIRT may engage third-party cybersecurity experts to evaluate and/or remediate the incident. If and when the CIRT is activated, the CISO will inform the Company's Chief Information Officer (CIO). In the event that the CIRT confirms that the incident relates to a cybersecurity incident or compromise of MGIC’s computer systems, the CISO will notify the General Counsel, who will advise the Chief Executive Officer ("CEO"), who is a member of the Board of Directors. In addition to advising the CEO, the General Counsel will also convene an established committee whose members include the General Counsel, Chief Financial and Risk Officer, Senior Vice President of Investor Relations, and Chief Accounting Officer in order to determine if the event is a material cybersecurity incident so as to trigger an Item 1.05 filing on Form 8-K. If a determination is made that the event is material, or if the CEO or General Counsel otherwise determines it advisable, the CEO or General Counsel, or a delegate thereof, shall notify the Chairman of the Board, Lead Independent Director, and Chairpersons of the Board’s Business Technology and Transformation Committee (the “BTTC”) and Audit Committee. To our knowledge, during the reporting period there were no cybersecurity incidents that materially affected or are reasonably likely to materially affect our business strategies, results of operations, or financial condition. For additional information about risks related to cybersecurity, see our risk factors titled “Information technology system failures or interruptions may materially impact our operations and/or adversely affect our financial results” and “We could be materially adversely affected by a cybersecurity breach or failure of information security controls."
