SABSA is a model and a methodology for developing risk-driven enterprise information security architectures and for delivering security infrastructure … As we can see in the image below, the synergy between the areas may be much greater than we previously imagined. This will inform the second phase, during which the enterprise’s security specifications are designed and mapped. As you see in the above picture I use IAF (Integrated Architecture Framework) as a model to build my architecture. Also, one of the weaknesses in Single-Tier models, upgrading, is no longer a problem as we can upgrade and modify systems much more easily. It is not uncommon for this type of structure to be the same user responsible for running applications, and often the most privileged user, who may be root for *NIX or even the Administrator for Windows systems. It is rather difficult to talk about cloud security architecture without first talking about the operational model. Multi-tier models are most effective for today’s security models and systems and are therefore best suited for building security-focused applications. Think Strategy: How To Secure Microservices. Thus, the importance of a better understanding is evident. One solution that should be pursued is always to seek to convey the right information about what Security Architecture is because in many cases people understand that it is nothing more than the creation of maps and diagrams of networks or services. It is an initiative explaining not how IT works, but what IT means for business. This is nonetheless important, but behind a secure application lies infinity controls, processes, layers, and structures that must work together for the end result to be a secure application. Thinking about software security is not just about improving your code or even writing more secure codes – there’s a lot more to it. We need to understand that the Security Framework is a process, and as such should be carried out by people and systems who understand its importance. I argue that security architecture is the designing of security controls in a defined scope with the goal to assure system security requirements. If you would like to know more about this point, in this Gartner’s article you can find more in-depth concepts about this structure. Don’t depend on secrecy for security Principles for Software Security 1. These may be enterprise architecture, technical design, organizational structure, policy framework, process catalog, or … This, in addition to being a service continuity issue – as we have a single point of failure – is also a weakness in the architecture, since if there is a compromise of the application, the database will eventually be damaged. They are ideally suited for organizations wanting to maximize their return on any security technology investment by evaluating their needs and validating the security of their existing deployments. Without it, you’ll be entirely dependent on individual security settings and inconsistent tactics. Cybersecurity Standards and Frameworks That´s a Technical Infrastructure architecture of a security system. A cyber security architecture combines security software and appliance solutions, providing the infrastructure for protecting an organization from cyber attacks.
