Enterprise Security Architecture in a Dynamic Environment
Security architecture is a unified approach to security design that takes a risk-based approach to protecting assets.
A security architecture covers regulatory and legal requirements, business processes, financial requirements and technology. It makes compromise more difficult and limits the impact of any compromise.
The benefit for organisations is to optimise security based on the specific circumstances of each organisation while minimising costs.
Throwing cybersecurity technology at your IT systems doesn’t lead to real security. Today, what we write in our policies, the behaviour of our employees and the preparedness and responses of our management teams to the crisis determines the financial penalties that organisations face when a breach occurs.
Without a coherent security architecture vulnerabilities will remain to be discovered by attackers. Security Architecture is a well-established principle in highly-secure networks to design security into IT - but it is far less prominent in commercial networks. It is increasingly important for today’s highly adaptive, cloud-based IT environments.
The UK Government’s National Cyber Security Centre (NCSC) defines security architecture as the practice of designing computer systems to achieve security goals.
Our mission, as enterprise security architects, is to develop and evolve an adaptive, risk-based, context-aware security architecture for your network infrastructure and its related security mechanisms, policies and procedures, for consistent operation within a modern dynamic organisational environment. The purpose of this is to ensure your organisation is able to operate safely in a dynamic threat and technological environment by effectively managing the risks to your information assets.

Enterprise security architecture links the components of the security infrastructure into one integral design, ensuring the right technology is deployed, reducing the risks of undiscovered vulnerabilities and reducing technology costs.
