Risk Assessments

Newrisk Limited can assist clients to identify and assess relevant risks so as to determine prevention counter measures and responses. This identification and assessment process involves catastrophic risk analysis based on a model developed from the original doctorate research work by Newrisk Limited's principal adviser, Dr Leivesley. For further details of this risk assessment modelling process as applied by Newrisk Limited, please follow this link.

Newrisk Limited's principal adviser, Dr Leivesley, has designed stress tests of critical functions for companies and govenrments so that analysis of, and responses to, identified lacunae and vulnerabilities can be based on outcomes which have been quantified from the stress test workshop and field exercises.

Brief exercising and testing is recommended and timing is based on an analysis of each client's "critical period": this may be an hour or even a five minute period, depending on the critical period when an organisation may self-protect or when people are deciding whether to evacuate or shelter in the workplace. In the cyber realm, decisions may be taken within a tight time frame and therefore responses to critical decisions may need to be pre-empted for the purposes of systems design, so as to recognise and respond to threats - for example, when milliseconds may impact on the integrity of a communications system.

Critical infrastructure such as power stations, petrochemical and gas plants, rail control rooms and rail tunnels always benefit from extremely brief field exercises that use maintenance time or other opportunities (such as board meetings) to test systems and personnel in a practical and cost effective manner. Workshop exercises in certain sectors, such as the banking and finance sectors, may be conducted via an international video conference or other form of social media.

  • TEG7
  • Cyber Threats
In response to the Paris & Brussels attacks, Newrisk Ltd has become part of The Exercise Group7. The TEG7 LLP is a dynamic team drawn from cyber & former special defence fields to exercise organisations & governments on emerging terror threats.  The TEG7 profile can be seen at www.teg7.co.uk.  The level of casualties from shooting attacks (as with the Bataclan (France) in 2015; Brussels airport (Belgium), Ataturk airport (Turkey), Nice beach (France) & Berlin Christmas Market (Germany) in 2016; & La Reina Nightclub (Turkey) in 2017) are the result of military style incursions by terrorists determined to maximise casualties.  Home grown terror threats are increasing in many countries - the New York & New Jersey bombs found in 2016 & the numerous disrupted plots in the UK, Germany & France - indicate serious changes in terror capability which may be made more dynamic as ISIS fighters return to their home countries.

Cyber threats are changing from loss of data & privacy to loss of control of business systems & more seriously reconnaissance attacks on critical infrastructure including energy grids.  The fragility of highly connected systems will become more serious in 2017 with open system dependencies (driven by business innovation).   Degraded capacity operations will become essential if persistent attacks affect critical infrastructure.  Exploiting cyber weaknesses are (i) criminals with ransomware & (ii) nation states aiming to disrupt, deter or signal capability against target countries.  The Ukraine power attacks remain a lesson for critical infrastructure losses.  Aviation remains the industry ‘canary’ for cyber failures & cyber forensics must evolve to close open investigations (as in the case of MH370).
