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 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.
