How can firms protect themselves from ransomware?

In a previous blog post I wrote about the rise of ransomware over the last year. In this post I will briefly outline what steps organisations should take to avoid becoming the next victim of ransomware. Continue reading “How can firms protect themselves from ransomware?”

The importance of having an Asset List

In July I attended and presented at the East Midlands Cyber Security Conference and Expo, at the National Space Centre in Leicester.

Asset List blog2In their presentations, Derbyshire’s Assistant Chief Constable –  Martyn Bates, Del Heppenstall – Director, KPMG, and Christian Toon – Cyber Security Specialist, PricewaterhouseCoopers LLP all mentioned in one way or the other the importance of maintaining an asset list.

In my presentation on Implementing Cyber Essentials, I also observed that while not a specific requirement of Cyber Essentials, in practice you will find it hard to manage a certified environment unless you have a good view of the complete list of assets.

There are lots of attempts to define the terms, write taxonomies etc. There is little point in duplicating this, however, here is how I think about the terms…

Are we Incentivising Staff to Break Security Rules?

In the article Security Zone: understanding why staff break the rules,
Andrew Kays describes some research undertaken by Nexor with cyberpsychology researchers at Nottingham Trent University to look at the underlying causes of sensitive data loss. The research looked specifically at the factors that influence human behaviour and people’s attitudes towards security, in particular their responses to rules defined in published security policies.
