In the 1970s and 1980s, computer security was mainly limited to academia until the conception of the Internet, where, with increased connectivity, computer viruses and network intrusions began to take off. Cybersecurity and cyber threats have been constant for the last 50 years of technological change.

While most aspects of computer security involve digital measures such as electronic passwords and encryption, physical security measures such as metal locks are still used to prevent unauthorized tampering.Ĭomputer security, cybersecurity, or information technology security ( IT security) is the protection of computer systems and networks from information disclosure, theft of or damage to their hardware, software, or electronic data, as well as from the disruption or misdirection of the services they provide.
