Risk Assessment Modelling

Newrisk Limited applies an original risk assessment model developed from original doctorate research work by Newrisk Limited's principal adviser, Dr Leivesley. To return to the overview of the risk assessment services provided by Newrisk Limited, please click here.

The catastrophic risk modelling used by Dr Leivesley was developed from an initial study of over 2,000 incidents in original research. This research provided key dimensions across all disasters and factors which caused a breakdown in critical functions of business and government. In the subsequent years, practical experience with managing disaster recovery units and providing catastrophic risk advice across a variety of industries has broadened the range of factors used in models to assess particular risks.

The catastrophic risk speciality covers all risks across all industries and disciplines where failures in a critical function may cause a total collapse of business processes, government policies and responses, crises from natural disasters, terrorism or major accidents. The health of populations is particularly dependent on catastrophic risk assessment as this discipline protects against mass casualties from disasters such as earthquakes, pandemics, terrorist actions or as a consequence of war.

The advantage of the risk modelling process applied by Newrisk Limited is that human factor failures can be included alongside technology, conflict, terrorism, technological processes and geopolitical inputs. Quantification of risk is an important contribution to business and government policies. Operational plans and the operational risk assessment work by Newrisk Limited's principal adviser, Dr Leivesley, allow stress testing, the exercising of existing procedures, the assessment of the cost effectiveness of any new controls being considered by organisations or governments to reduce the risk of catastrophic loss or otherwise mitigate incidents in real-time.

  • Security 2018
  • Cyber!

Walk-in attacks by terrorists with guns, improvised explosive devices, knives & other weapons are happening in 2018. France has started to suffer significant threats from attacks directed at police using vehicles & guns.  Heroic police actions to protect the public have united the country.  In England, an attack using Novichok nerve agent on the former Russian Spy Sergei Skripal in Salisbury  has increased business sensitivity to international tensions & unconventional weapons.

Regulatory compliance with GDPR will be the top challenge for companies in 2018.   Nation State, organised crime and individual hostile cyber actors can be mitigated by well-trained workforce teams & confident, adaptive & innovative leaders. Cloud & third party providers & insider threats add to the regulatory burden on business. When one mastermind criminal can take a billion dollars out of the financial sector in four years the scale of business losses to poor performance in cyber operations is obvious.  Energy, banking and transportation are high risk targets and organisations with static unchanging security practices are possible consequential victims.
