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.

  • TEG7
  • Cyber Threats

In response to the Paris & Brussels terror attacks, Newrisk Ltd became a founder member of The Exercise Group7 LLP (TEG7) which is a dynamic team drawn from cyber & former special defence fields to exercise organisations & governments on emerging terror and cyber threats.  The TEG7 profile can be seen at www.teg7.co.uk. The Manchester Arena suicide bombing in May 2017 highlights a new military style of terrorism from ISIS with a greater potential to attack the public & security personnel in many countries.  TEG7 integrates physical & cyber security for corporate exercises to protect against terror & cyber-attacks.

Delta & British Airways have suffered a world-wide loss of aviation business systems as a result of computer system outages.  Newrisk Limited - as part of The Exercise Group7 LLP - conducts exercises in integrated cyber & physical security transformation for companies & governments.  Cyber threats are becoming more serious for critical infrastructure & require new principles in management & exercises of personnel to pre-empt crises. Degraded operations will become a fall-back if persistent attacks continue to exploit vulnerabilities & use ransomware or nation state motivated attacks. The Ukraine power grid attacks are a key lesson for infrastructure protection. Aviation remains the industry ‘canary’ for cyber failures.
