Security architecture and security design are both important parts of how IT works and how professionals try to keep systems safe. But these two parts of security are different and can’t be switched. To know what the difference is between security architecture and security design, you would have to know a lot about both.
On the one hand, a cyber security architecture is the set of parts and resources that make security work. In cyber security architecture, we talk about how security systems are set up and how the different parts that make up the security architecture work. To deal with cyber security architecture, you could look at a resource like a network monitor or security software program in the context of the whole system.
On the other hand, “security design” refers to the techniques and methods for putting hardware and software parts in places that make them more secure. Handshakes and authentication are parts of the design of a network’s security.
The operations and functions of the two terms are different, and as was already said, you can’t use them interchangeably. Let’s talk about each of the domains on its own so you can see how they are different.
What is Cyber Security Architecture?
Cyber security architecture can be described in different ways, but at its core, it is a set of security concepts, procedures, and models that are meant to fit your goals and keep your company safe from cyber threats.
Architecture is the process of turning business needs into security requirements that can be met in the real world. It also includes finding and evaluating possible threats and weaknesses, as well as recommending or putting in place the right security measures to reduce risks.
The Following Are the Main Parts of the Cyber Security Architecture:
- Security policy: This says how an organization plans to keep its systems safe and what should be done if a breach happens. A good policy has rules for privacy, availability, and reliability, as well as rules for how to use the information. It should also say who is responsible for making sure that each system is protected as the policy says.
- Security strategy: This is how a company plans to protect its systems and what resources will be used to do so. One solution could be to hire more people. Another could be to put money into better technology. The risk management strategy should also include finding weaknesses and coming up with a plan to stop them from happening again.
- Security program: A security program is everything that an organization does to make sure that its systems are safe. Some of these things are testing, monitoring, reviewing, patching, documenting, and training.
Developing cyber security architecture is based on three main goals: stopping attacks, making them less harmful, and looking into events quickly to stop them from happening again. All companies must deal with these problems if they want to be seen as safe.
What is Cyber Security Design?
It’s called “cyber security by design” when an architect makes plans for a building. The most important parts of security have always been there.
Here are the main ideas behind designing for cyber security:
Establishing Context Before System Development
Before you can build a safe system, you need to understand how it works and take steps to fix any flaws you find.
Developing with security in mind means using ideas and techniques that make it harder for attackers to mess up your data or systems.
Make Disruption a Challenge
When important or high-value services are provided by technology, it is very important that the technology is always available. In these situations, the allowed amount of “down time” can be close to zero.
Make It Easier to Detect Compromise
Even if you do everything you can, there is still a chance that a new attack or one you don’t know about will hurt your system. You should have the right tools to find signs of compromise so that you have the best chance of catching these attempts.
Reduction of Compromise’s Influence
Plan to naturally lessen the impact of any tradeoff. Again, there is the cyber security infrastructure design document, which is an important part of developing and putting in place security.
The Security Infrastructure Design Document helps to record and keep track of the information that is needed to describe the architecture and system design and give information about the security architecture of the IT environment that will be built.
This includes finding any standards, rules, and regulations that may apply and have an effect on how technology is chosen and put into place. The SIDD makes it clear what needs to be done to protect an organization’s network by listing the things that are needed for good security design.
These elements include finding threats, mapping systems and processes, figuring out risks, making a security policy, installing physical and technical controls, training staff, and keeping an eye on security activities.
The SIDD should be changed as needs change or as new risks come up. A cyber security architecture course is available for architects, just like any other cyber security specialization, and there are also certifications. For people who want to work in cyber security architecture, it would be best to start with a good cyber security course.
