Secure By Design
Experts in supporting your organisation through your Secure By Design Activities from the start
Business Context and Requirements
There has been a strategic shift across Government and Defence in how organisations approach security. This shift is designed to enable a culture of proactive risk management and appropriate security consideration throughout a capability's lifecycle, where policies are no longer something to refer or adhere to only at the point of implementation, but are guard rails connecting cyber security principles, roles, processes, tools, and techniques used throughout the lifecycle to achieve secure outcomes.
In broad terms this means that for a solution or system to be secure by design, security needs to be designed into systems and services from the very start of a project, rather than be added as an afterthought at a later stage.
At Nexor, the approach of implementing security from the start of a project has been fundamental to the way we have always worked with our clients and designed and developed our own solutions. It is embedded in our company culture of Security Mindfulness and outlined in an overview of our approach.
How we can help
Nexor work with you to understand and document your business goals and requirements, and then help you fully understand your security objectives and information flows and how they fit into your organisation’s operational architecture. Nexor will also identify any threats and risks that would need to be managed in allowing the appropriate trade-off between confidentiality, availability, usability, and integrity of data. From this we can facilitate the design of suitable architectures and solutions that support the necessary data flows to enable efficient and secure operations.
Nexor consultants can then assess the application architecture by building a picture of all the required data flows, and on a per-data flow basis, identify the specific security policy that needs to be enforced to enable that flow. Nexor also offers Solution Design Services with specific focus on emerging principles such as Zero Trust Principles, Data Centric Security or High Assurance Information Exchange in Cloud Environments.

Embedded Security Architect into Programmes
Nexor’s security architects often become part of a customer team, working closely with you on the planning and design of the project. This is an important part of the Secure By Design approach, in the security design as an embedded position in the project, in everything from design through to implementation, test and through life management
Security Assessment
Nexor provide a bespoke cyber security assessment service tailored to the needs of your organisation, considering your threats, vulnerabilities and risks and your ability to mitigate them. Leading on from the assessment, Nexor’s consultants will provide mitigation advice and develop security improvement plans to help you move forward. Security Assessment Services can range from supporting major Defence and Government programmes as domain specialists, to a short threat/risk assessment for a small organisation.
Supply Chain Assessment
As Supply Chain attacks become more frequent, it is important that you understand the risk to operations if your Supply chain is targeted to gain access to sensitive information relating to components of your solutions or services.
Nexor can extend the Security Assessment to include your Supply Chain, mapping your solution bill of materials or end to end service onto your Supply Chain to assess again your defined security standards and policies to identify any vulnerabilities and risks associated with it. Each part of that supply chain will be assessed to then build a complete picture of your supply chain.
Solution Architecture & Design
Once your information exchange requirements are fully understood, Nexor can support you to design a solution / architecture that will meet those requirements and make compromise difficult.
Our experience is based upon many years of designing and implementing secure solutions utilising our market knowledge, architectures and policies and an understanding of the nuances needed to integrate them seamlessly. These architectures will outline the types and numbers of different components needed to solve your information exchange requirements, whilst also minimising any disruption in service or compromise to security
Nexor can also provide you with a solution design where our consultants will also recommend specific products and services and policies to ensure that it can be seamlessly integrated with your existing systems. Many of the design considerations will include the operation and monitoring of the solution, ensuring it is resilient to attack but easier to update and monitor, such as integration to your Security information and Event Management (SIEM) systems
The benefits of a Secure By Design approach are:
Cyber security risk is seen as a business risk.
Digital and Security specialists work collaboratively together and can build new digital services faster and to common specifications to build cross-department trust.
Compromise is difficult as security vulnerabilities are anticipated, along with invalid user input. By using "good" software design practices and concepts and techniques can be applied early in the design process to enhance security down the line.
Disruption is difficult as systems can be designed in a way that is resilient to denial of service and similar attacks.
Compromise detection is easier as systems should be designed so that unauthorised or suspicious activity should be flagged as quickly as possible.
Reducing the impact of compromise through the design of systems that minimises the potential impact if a particular aspect is compromised.
