Operation AuroraAmericans are becoming heavily dependent on modern technology, which produces greater vulnerability to cyberattacks such as security breaches. Cyber ​​security, also known as computer security, is information security applied to computers and computer networks. It is designed to protect networks, programs, computers and data from attacks. These attacks can cause damage or unauthorized access to data. Cyber ​​security also includes protection from unexpected events and natural disasters. The main function of computer security is to protect computers, networks, programs and data from inadvertent or unauthorized access, modification or destruction. Confidential computer information is collected, processed, stored, and data is transmitted across networks to other computers by military, corporations, financial institutions, and government. There is a rapid growth in the volume and complexity of cyber attacks. This requires constant attention to protect sensitive personal and business information, as well as safeguard national security.

According to the nonprofit organization Privacy Rights Clearinghouse, between January 2005 and May 2008, 227,052,199 records containing sensitive personal data were found to be involved in security breaches in the United States.
