Interview with Michael Fischerkeller – Author of Cyber Persistence Theory

Cyberspace is a completely different third strategic environment from traditional strategic environments. Adversaries are constantly in contact with each other due to interconnectivity. Countries exploit their adversaries’ vulnerabilities for their own benefit. The cumulative effect can exceed the benefits of traditional warfare. Interview with Eugene H. Spafford, Professor of Purdue University

Spafford claims that the top priority of cybersecurity should not be security itself. Cybersecurity should protect users and their activities from attackers and losses, in order to support users in achieving their original goals.

He also said that the understanding that defense always fallen offence is a major misconception. It is not always true that offence is easier than defense. In addition, he said that a common problem is the pile-up of security tools. This is due to the misconception that the more tools there are, the more secure it will be.
