Foreword to first version

This book was first produced in response to a computer hacking incident encountered during 2020 by the author of the first version of this book, in the course of his being a self-employed software developer. He had already adopted some security measures but then felt he really needed an overhaul of the security measures and systems he had in place.

This book is aimed specifically at individuals, sole traders, and small businesses, bearing in mind that they may have shoestring budgets.

It was the author’s belief that end-user security was a real issue of concern because the mindsets of security specialists seemed to be often attuned to examining and proposing solutions within rigid frameworks: such as for example only looking at software security risks but completely ignoring physical aspects of everyday nuts-and-bolts security. A certain element of being able to think ‘outside the box’, and outside one’s own specialised domain, is needed. As such, security is really a multidisciplinary field, requiring the creativity of people from all walks of life.

There is special concern for the highlighted entities (individuals, sole traders, and small businesses), because of their being prone to attack due to budget constraints, and a lack of other important resources.

The author of the first version of the book places his contributions into the public domain (the author’s Google Drive version hosted here [minus the Google Docs comments] will always be in the public domain). He feels that end-user security is so important, that intellectual property obstacles should be removed as much as possible, so as to enable everyday users to be able to undertake computing activities safely. This is especially of concern at the time of writing during the 2020 COVID-19 worldwide outbreak. During this outbreak, individuals are being called upon in great numbers to remote work and also to socialise and conduct recreational activities using computing devices.

The increasing consumer use of cryptocurrencies is another reason why a work like this is important.
