Computer Hacking: Computer Systems

Hacking is breaking into computer systems, frequently with intentions to alter or modify existing settings. Sometimes malicious in nature, these break-ins may cause damage or disruption to computer systems or networks. People with malevolent intent are often referred to as "crackers"--as in "cracking" into computers. Source:

The report found numerous weaknesses that permitted unauthorized access to the medical information of Medicare recipients. Director of the FBI's National Infrastructure Protection Center, said there are currently 102 open investigations of computer intrusions into government systems, and the bureau is keenly aware of the rise of state-sponsored hacking. Only 5 to 10 percent of federal agencies use automatic security detection programs and 80 percent of incidents go unreported. The government's lack of safeguards against domestic and foreign attackers who struck 32 federal agencies last year is "chilling," one congresswoman said. Source:
