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 Mississippi, cybersecurity is governed by a combination of state statutes and federal laws designed to protect computer systems and sensitive data from cyber-threats. The Mississippi Code includes provisions that address computer crimes and unauthorized access to computer systems under Title 97, Chapter 45, known as the 'Mississippi Computer Crimes Act.' This Act makes it illegal to knowingly and willfully commit various computer-related offenses, such as computer fraud, unauthorized access, and the introduction of computer viruses. Penalties vary depending on the severity of the crime and can include fines and imprisonment. Additionally, businesses in Mississippi must comply with federal laws such as the Computer Fraud and Abuse Act (CFAA) and the Cybersecurity Information Sharing Act (CISA), which provide a framework for criminalizing certain cyber activities and encourage sharing of cybersecurity threat information. Businesses that handle personal information are also subject to data breach notification laws, requiring them to notify affected individuals if their personal information is compromised in a cybersecurity breach.
