A Comparative Study of Cyberattacks

Open Access

Abstract

Cyberattacks are computer-to-computer attacks undermining the confidentiality, integrity, and/or availability of computers and/or the information they hold. The importance of securing cyberspace is increasing, along with the sophistication and potential significance of the results of the attacks. Moreover, attacksb involve increasingly sophisticated coordination among multiple hackers across international boundaries, where the aim has shifted from fun and self-satisfaction to financial or military gain, with clear and self-reinforcing motivation; for example, the number of new malicious code threats worldwide increased more than 71% from 2008 to 2009.
