A Matter of Trust

There is a continuous stream of security-related bug reports permeating the news these days. With all the

noise, it is difficult to spot the core issue, let alone to keep one’s eye on it. The simple questions of what one

trusts and why one trusts it are often ignored. Moreover, the need to define both inter-and intra-

infrastructure trust relationships is often overlooked. The core question of what trust is and its importance

is usually forgotten altogether. Security is a matter of trust. This chapter explores the nature of trust and

trust relationships, and discusses how one can use trust to build a secure infrastructure.
