Iowa's private-sector security posture rests on a cybersecurity tort-liability affirmative defense, Iowa Code chapter 554G (554G.1 to 554G.4, added by 2023 Acts, ch. 63 (H.F. 553)), reaching a covered entity, a business defined to include a financial institution and an entity organized under chapter 28E but not a municipality, that accesses, receives, stores, maintains, communicates, or processes personal information or restricted information.
A covered entity that creates, maintains, and complies with a written cybersecurity program with administrative, technical, operational, and physical safeguards, funded at or above its own calculated maximum probable loss from a data breach, and that reasonably conforms to a named industry-recognized framework (the NIST Cybersecurity Framework, NIST SP 800-171, NIST SP 800-53 and 800-53A, the FedRAMP Security Assessment Framework, the CIS Critical Security Controls, or the ISO/IEC 27000 family) or an applicable regulatory regime (Health Insurance Portability and Accountability Act (HIPAA)'s Security Rule, Gramm-Leach-Bliley Title V, the federal Information Security Modernization Act, HITECH, or Iowa's own Insurance Data Security Act, chapter 507F) gains an affirmative defense to a tort claim alleging that a failure to implement reasonable information security controls caused a data breach.
The chapter imposes no duty to adopt a program, names no regulator and no penalty, and, under 554G.4, creates no private right of action of its own: it is a defendant's shield raised in litigation another statute or the common law already permits, never a plaintiff's remedy.
Separately, the Insurance Data Security Act, Iowa Code chapter 507F (2021 Acts, ch. 79), requires a licensee under Iowa's insurance laws (with carve-outs for a licensee already compliant with HIPAA or Gramm-Leach-Bliley) to develop, implement, and maintain a risk-assessment-based information security program, investigate a cybersecurity event, and notify the commissioner of insurance within three business days of confirming a reportable event; a licensee with fewer than twenty workers, under five million dollars in gross annual revenue, or under ten million dollars in year-end total assets is exempt.
Because 507F's bound party, an insurance licensee, is a role the LexLint activity vocabulary cannot yet express, it is deferred rather than flagged on a guess (#6740): no instrument for it is filed here, and it is recorded in this summary so a reader knows it exists.
No Iowa statute setting security requirements a connected device or software product must meet before or after it reaches the market, comparable to California's, Oregon's, or the Cyber Resilience Act's connected-device or product duties, is described here; none was located across the source dossier already researched for this jurisdiction (Iowa Code chapters 103A, 335, 414, 423, 455B, 476, 507F, 554G, 700 through 728) or in a further search for one, so this is a researched absence rather than a gap in coverage.
No general Iowa statute requires a private business to report an exploited vulnerability or a security incident to an authority, a CSIRT, or users, outside the insurance-sector duty above; none was located. Iowa's breach-of-security notification duty, Iowa Code 715C.2 (Personal Information Security Breach Protection), is already this jurisdiction's privacy row and is not repeated here.
The Iowa Consumer Data Protection Act's own security-of-processing clause, Iowa Code 715D.4(1), requiring a controller to adopt and implement reasonable administrative, technical, and physical data security practices appropriate to the volume and nature of the personal data at issue, is a section of that comprehensive privacy regime and stays with this jurisdiction's privacy row rather than being researched a second time here.
Iowa Code 716.6B, unauthorized computer access, is an offense committed by the person accessing a system rather than a duty on the system's operator or manufacturer, so it belongs to this jurisdiction's scraping row and is not a security-topic presence on its own.
