IT Security and Building Resilient Infrastructure

How does resilience impact IT Security? Without resilience in an IT Estate your business can quickly find itself ceasing particular activities because of events outside of your control.

Data Loss Prevention – why it matters

Data Loss Prevention (DLP) Every organisation in the UK that handles data digitally must register with the Information Commissioner’s Office and take reasonable steps to protect the integrity of their data.

Cloud Security – a different perspective

Taking a leaf from Kendo when talking about Cloud Security Kendo is ‘The Way of The Sword’ – a martial art heavily rooted in Buddhism and seeks to build a culture of striving for improvement.

Security first: why good enough isn’t good enough anymore

The Computer Security challenge Most solutions require an internet connection and are therein contactable through the internet – be this an internal network (such as within the office) or an external one (through the world-wide-web) such as a web-interface. This is why since 2020 ransomware has become increasingly dangerous for the global economy, from small and medium sized businesses to government departments or critical infrastructure.

Militaries plunder science fiction for technology ideas, but turn a blind eye to the genre’s social commentary Pavel Chagochkin/Shutterstock Will Slocombe, University of Liverpool Military planning is a complicated endeavour, calling upon experts in logistics and infrastructure to predict resource availability and technological advancements. Long-range military planning, deciding what to invest in now to prepare armed forces for the world in thirty years’ time, is even more difficult. One of the most interesting tools for thinking about future defence technology isn’t

The Conversation, on Responding to Cyber Warfare

Should cyberwar be met with physical force? Moral philosophy can help us decide seaonweb/Shutterstock Christopher J. Finlay, Durham University In conventional warfare, it’s accepted that if a state finds itself under attack, it’s entitled to respond – either with defensive force, or with a counterattack. But it’s less clear how countries should respond to cyber-attacks: state-backed hacks which often have dangerous real-world implications. The 2020 SolarWinds hack, attributed to state-backed Russian hackers, breached security at around 100 private companies. But it
