ABSTRACT
The 'traditional' approach to cyber security, and one that most senior managers will be aware of, involves the protection of corporate information within a corporate network. Information technology (IT) managers are seen as people who guard against intruders by using complicated 'firewalls' and anti-virus software. Traditionally IT professionals defend network perimeters, in an attempt to keep malicious people out. Security firm Kapersky Labs reported up to $1 billion had been compromised and possibly stolen in a phishing attack that enabled Carbanak 'back door' malware to be downloaded to the IT networks of up to 100 financial institutions. 'Denial of Service' (DoS) attacks are very common and are designed to stop the website from working. These attacks target the Domain Name Server (DNS). Domain Name Servers are computers that act as the telephone directories of the Internet. In the spring of 2013, the Internet was slowed down by a massive Denial of Service attack by Cyberbunker.
