Assess – What problems are you trying to solve?

OT environments are related to traditional IT networks, but they’re different in crucial areas. With the rise of devices, physical infrastructure and process control being digitised, the role of the network connecting all of these devices has become ever more crucial.   This convergence of IT and OT, especially from a network standpoint means that security standards must be more rigorous and carefully managed.

Denver provides an independent OT Security Health Check & Maturity Assessment, benchmarking our client's OT systems against best practices and other businesses of comparable size, complexity, and industry.

This practical risk assessment will identify mitigation measures, and uncover opportunities for modernisation and improvement, whilst providing a clear and concise Action Plan, Design Roadmap, and strategy to take our customers to OT security maturity and alignment with industry standards. 

Utilising an Agile, outcome-based approach, Denver follows a four staged delivery framework to initiate and plan, workshop, analyse, and present findings.

Architect – How are we going to solve them?

All good security practice starts with policy, but it is equally important to turn those principles into security architectures that support governance efforts. This can involve refining existing infrastructures or implementing whole new designs as part of modernisation programmes. In the OT environment, this often means ensuring that infrastructure such as SCADA and process automation systems are “air-gapped” from the rest of the organisation, due to their security, safety and commercial sensitivity, but also able to be integrated with key business systems to realise efficiency gains.

Denver has the expertise and experience to provide architectures and designs that help clients effectively navigate the competing security and operational requirements in OT environments.

IT/OT Security and Architecture Strategy Development

Denver's core principles and framework are in alignment with NIST (National Institute of Standards and Technology).

Following these principles, Denver provides our resource and energy clients with the following Security and Architecture Strategy Development services:

• Taking our clients IT/OT strategy and roadmap items/priorities from assessments and building security policy frameworks for later implementation.
• Independent evaluation of proposed OT architectures and policy frameworks and benchmarking them against best practice.
• Assessment of proposed solutions from third party vendors and providing oversight, as well as ensuring alignment against corporate standards.
• Network design and architecture with the appropriate segregation of IT and OT infrastructure.
• Facilitating integration between OT and IT systems without compromising security.
• Enabling remote management of OT without compromising security.

OT Network Architecture Consulting

• Reviewing existing designs and recommending architectural changes and opportunities for improvement
• Acting as the central coordination point for:
  • Designing OT architectures, especially those that converge with IT networks
  • High-level and low-level designs of new and upgrades to existing OT architectures
