The cost-to-benefit tradeoff of a successful cyber-attack, and the availability of the internet as a delivery mechanism, effectively arms the masses With the right skills, anyone, anywhere, can launch a potentially devastating cyber-attack Several of these attacks were discussed in a recent whitepaper that analyzed the cyber-attack capabilities and vulnerabilities of Libya under the anti-Gadaffi uprising... infrastructure control & sabotage Political reasons Personal entertainment In the next section, we shall see how recent cyber-attacks are being targeted to realize these objectives and describe their potential impact to information systems and organizations 24 Security Enhanced Applications for Information Systems The actors that typically have these motivations can be categorized as: organized groups;... motives, it appears that they seek organizations with a low-security profile to publically embarrass at every opportunity A lone wolf or solo hacker, often incorrectly stereotyped as a basement-dwelling spotty teenager, can in some instances pose an equal threat An example of the lone wolf includes the case of the Scottish systems administrator, Gary McKinnon, and is perhaps one of the more famous of these... infrastructure Pivoting attacks are a severe form of web-based attacks as they allow attackers to completely bypass perimeter security controls at the network edge Web attacks involve the attacker identifying a potential vulnerability in a web system There are several types of vulnerabilities that allow for different forms of attacks The most common of these are cross-site scripting (XSS) and SQL injection Cross-site... day-to-day operations often omit security entirely from consideration At best it is an afterthought, akin to putting a ‘do not steal’ sign on the aforementioned vehicle and hoping this will deter all potential criminals In 2010, for the first time, the worldwide cost of information and electronic data theft (excluding piracy) rose 9.3% from 2009 to surpass all other theft (Kroll, 2010) In the UK alone,
