Background

Currently everybody’s everyday and professional activity is getting more and more dependent on the use of computers and software. So, there is a evidently a growing need in trustworthy computing, since “cyber-attacks” may happen every day, hour, or minute, and can lead to fatal consequences, from a crush of some data or the whole computer system, till a fault of some company or even the death of a live organism somewhat controlled by a computer. The book (Schneider, 1999) considered to be a classical book on trustworthy computing defines this term as follows: “Trustworthiness is assurance that a system deserves to be trusted – that it will perform as expected despite environmental disruptions, human and operator error, hostile attacks, and design and implementation errors. Trustworthy systems reinforce the belief that they will continue to produce expected behavior and will not be susceptible to subversion.”

The concept of trustworthy computing is wide and based on a number of scientific, engineering, business, and human factors. This article primarily focuses on trustworthy software development.
