Secure by Design, Resilient by Architecture: Security Architecture
Security architecture is a critical discipline within both on-premise and cloud systems, designed to ensure that the infrastructure, applications, and data within an organization remain protected against evolving cyber threats. The methodology behind security architecture involves a comprehensive approach to designing, building, and maintaining secure systems by incorporating security principles from the outset. For both on-premise and cloud systems, security architecture aims to define a robust framework that ensures the confidentiality, integrity, and availability (CIA) of systems, and effectively mitigates risks such as unauthorized access, data breaches, and service disruptions. The key difference between the two environments lies in the challenges they present—on-premise systems are typically controlled and contained within an organization’s perimeter, while cloud environments require additional considerations for data sovereignty, multi-tenant security, and shared responsibility models.
One of the most widely recognized frameworks for developing security architecture is SABSA (Sherwood Applied Business Security Architecture). SABSA is a risk-driven methodology that helps organizations align security goals with business objectives. It provides a structured approach to building a security architecture that spans both the business and technical levels, focusing on business requirements and mapping them to appropriate security solutions. In the context of on-premise systems, SABSA enables security professionals to design architectures that are tightly integrated with the organization’s overall business strategy, ensuring that security measures align with organizational goals. For cloud systems, SABSA helps to adapt security models to new challenges, such as dealing with shared cloud environments and ensuring that security policies can accommodate the distributed nature of cloud resources. SABSA’s comprehensive focus on risk management and its integration of security into the business decision-making process make it highly effective for both on-premise and cloud deployments.
Another key framework in security architecture is TOGAF (The Open Group Architecture Framework). While TOGAF is primarily focused on enterprise architecture, it also includes vital elements related to security, particularly when it comes to structuring secure IT environments. TOGAF’s architecture development method (ADM) helps in planning, designing, implementing, and governing enterprise IT systems, with security considered as an integral part of the overall architecture. When applied to on-premise systems, TOGAF allows for the creation of a security architecture that integrates with the organization’s infrastructure, aligning network designs, access control systems, and data protection strategies with business objectives. In cloud environments, TOGAF provides a broader view that can accommodate the complexity of hybrid systems, ensuring security measures account for the various security models and shared responsibilities inherent in public and private cloud services. By embedding security considerations into the architecture’s planning phases, TOGAF ensures that security is not bolted on as an afterthought but built in from the ground up.
F
or cloud-specific security architecture, Cloud Security Alliance (CSA) and NIST SP 800-53 also play pivotal roles in providing a framework for secure cloud computing. The CSA Cloud Control Matrix (CCM) offers a comprehensive set of security controls designed specifically for cloud environments, addressing areas such as data encryption, identity and access management, and security operations. The NIST Cybersecurity Framework, on the other hand, is an essential guide for protecting cloud environments through risk management processes and aligning cybersecurity activities with business objectives. NIST emphasizes the need for identifying, protecting, detecting, responding to, and recovering from security incidents in cloud systems. This framework can be applied across both on-premise and cloud systems, but for cloud environments, it focuses heavily on securing cloud infrastructure and ensuring proper monitoring and risk management, considering the shared responsibility model between cloud providers and consumers.
Incorporating security into both on-premise and cloud systems requires continuous monitoring, testing, and adaptation of the security architecture to stay ahead of evolving threats. Continuous assessment and security testing, such as penetration testing and vulnerability scanning, are essential to maintaining a robust security posture in both environments. In on-premise systems, this often involves monitoring network traffic, validating access controls, and securing physical infrastructure. For cloud systems, the focus shifts to monitoring multi-cloud environments, managing identity and access controls across providers, and securing APIs and cloud services interacting with external partners. Radix, as a solution provider, offers expert guidance in implementing these practices with specialized security frameworks like ISO 27001, CIS Controls, and NIST for both on-premise and cloud infrastructures. Radix ensures organizations build resilient security architectures that are agile, scalable, and capable of mitigating risks in both traditional IT and cloud environments.
