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.

  • Cyber
  • Nuclear

Prepare for the unexpected. New forms of attack will be unexpected in time, tactics and consequences and may include kinetic attacks on undersea cables and space infrastructure. 

Questions to Consider:
Does the organisation have a capacity to fast switch to other cloud, in-house server or hot site operations to limit recovery time? Are there diagnostics for sensors and control systems and the interface with operations?  Could a global security crisis in the South and East China Seas and flash points elsewhere (including Europe) target an organisation’s upstream cyber providers?  Other resilience tasks to check are:

  • - Competent external recovery services;
  • - Internal policies for real time back- up systems unconnected to live operations;
  • - Financial resources for full re-build after ransomware;
  • - Internal policies to avert ransomware payments; 
  • - Cooperative recovery planning with industry peers;
  • - Regular modular and  whole of organisation exercises;
- Multiple scenario tests for strength of preparedness.

 Nations signalling intent of conflict.
 Energy regeneration challenges.

Nuclear conflict and radiation incidents are a high risk for some regions.  Nations are engaging in
‘signalling’ capability of weapons and intent. The most frequent signals are coming from China in
relation to Taiwan; the USA in relation to freedom of navigation in the South China Sea; Russia in
sending Zircon hypersonic missiles onto naval voyages into the Atlantic, movement of nuclear
weapons to Belarus and threats to Ukraine; North Korea in frequency of missile tests including
submarine launched missiles and drones; and Iran’s apparent nuclear enrichment found to be at
84% purity.

Planning for Energy Regeneration Post Nuclear Conflict:
1. Hardened energy infrastructure;
2. Academic and Industry collaborative Programmes;
3. Small Modular Reactors built underground;
4. Supplemental critical control system separated from IOT; and
5. Energy planning for rail transportation of populations.
