The book provides a general discussion and education about information security breaches, how they can be treated and what ISO27001 can offer in that regard, spiced with a number of real-life stories of information security incidents and breaches. These case studies enable an in-depth analysis of the situations companies face in real life, and contain valuable lessons your organisation can learn from when putting appropriate measures in place to prevent a breach. The author explains what your top priorities should be the moment you realise a breach has occured, making this book essential reading for IT security managers, chief security officers, chief information officers and chief executive officers. It will also be of use to personnel in non-IT roles, in an effort to make this unwieldy subject more comprehensible to those who, in a worst-case scenario, will be on the receiving end of requests for six- or seven-figure excess budgets to cope with severe incidents.
