Cybersecurity is the process of protecting internet-connected computer systems, such as hardware, software, and data, from cyber-threats. Cybersecurity is used by individuals and businesses to protect against unauthorized access to these computer systems when cyber criminals attempt to change, destroy, and steal sensitive data; extort money by making the systems unworkable; and interrupt business operations.
In Wisconsin, cybersecurity is governed by a combination of state statutes and federal laws designed to protect computer systems and sensitive data from cyber-threats. The Wisconsin Statutes cover various aspects of computer crime under Chapter 943, which includes offenses such as unauthorized access to computer systems, damage to computer data or programs, and possession of hacking tools. Additionally, businesses in Wisconsin must comply with the Wisconsin Data Breach Notification Law, which requires entities to notify individuals if their personal information is compromised in a security breach. At the federal level, laws such as the Computer Fraud and Abuse Act (CFAA) and the Cybersecurity Information Sharing Act (CISA) provide a framework for criminalizing unauthorized access to computer systems and facilitating the sharing of cybersecurity threat information. These laws work in tandem to deter cybercrime, mandate reporting of data breaches, and encourage the protection of critical infrastructure from cyber-threats.
