To a large extent liability for ICT perils is still a grey area, even though an increasing number of information security researchers adopt economic approaches to highlight market mechanisms and externalities. That is why this article focuses on the need for increased awareness of externalities and liability among ICT professionals and their customers. This is critical to achieve in order to promote appropriate ICT technologies and services with comprehensible privacy and security protection.

What is needed is a better understanding of the consequences of externalities from ICT perils. This would benefit customers and increase trust in ICT products and services which in turn may even increase suppliers' profit margin; customers would be prepared to buy more services and products if contracts and service level agreements would accept more liability. Moreover, suppliers could sell guaranties and insurances on top of their products and services. The result would be a win-win situation and would benefit society at large.
