Cyberattacks, data breaches and other cyber incidents, and various information security issues create enterprise-level risks for many organizations. Corporate boards must understand these issues and provide governance and oversight to ensure the organization meets reasonable data security practices standards. This Toolkit provides resources to help organizations address cybersecurity issues at a corporate level, including due diligence for merger and acquisition (M&A) transactions. For detailed guidance on developing and maintaining a comprehensive information security program and responding to cyber incidents, see Cybersecurity Toolkit (US).
