The Role of Internet Service Providers in Cyber Security

Internet insecurity is a worldwide problem that has generated a multitude of costs for businesses, governments, and individuals. suggests that one significant factor in these cyber security problems is the inadequate level of security maintained by home users and small businesses. Attackers compromise the computers of such users, developing networks of " zombies " or " bots " (called " botnets ") through which they send large amounts of spam and conduct other malicious activity (Markoff, 2007). Unfortunately, home users and small businesses are often unaffected by such activities and thus lack the incentives to invest in a security plan that approaches the socially optimal level of security, thus making all users less secure (Schneier, 2007b). Economists refer to such an issue as a " free rider " or " public goods " problem (Anderson & Moore, 2006). A handful of research studies and security experts have suggested that Internet Service Providers (ISPs) may be in a good position to cost-effectively prevent certain types of malicious cyber behavior, such as the operation of botnets on home users' and small businesses' computers (e.
