SY0-701 3.1: Architecture Models and Security Implications

Security+ Topic

Architecture Models and Security Implications for Security+

This Security+ topic covers cloud ownership models: cloud, responsibility matrix, hybrid considerations, third-party vendors, infrastructure as code, IaC, and serverless; Application architecture models: microservices, containerization, virtualization, centralized designs, decentralized designs, and on-premises designs; Network and industrial models: network infrastructure, physical isolation, air-gapped environments, logical segmentation, SDN, IoT, ICS, SCADA, RTOS, embedded systems, and high availability as an architecture concept; Architecture tradeoffs: availability, resilience, cost, responsiveness, scalabil...

4 lessons in this topic

1

Cloud And Shared Responsibility Models

Compare cloud, hybrid, third-party, responsibility matrix, serverless, and IaC implications for security ownership.

2

Modern Application Architecture Models

Explain security implications of microservices, containers, virtualization, centralized versus decentralized designs, and on-premises architecture.

3

Network And Industrial Architecture Models

Differentiate physical isolation, air gaps, logical segmentation, SDN, IoT, ICS/SCADA, RTOS, embedded systems, and high-availability architecture implications.

4

Architecture Security Tradeoffs

Evaluate architecture tradeoffs such as availability, resilience, cost, responsiveness, scalability, deployment ease, risk transference, recovery, patchability, power, and compute.

Common mistakes to avoid

1

The most common mistake is assuming cloud means the provider owns all security. The correction is to ask which layer is involved and check the responsibility matrix. Another common mistake is treating serverless as securityless.

2

Learners often confuse containers and virtual machines. The correction: containers share the host OS kernel, while virtual machines run guest operating systems on a hypervisor.

3

Learners often treat air-gapped as impossible to compromise. The correction is that air-gapped reduces network exposure but does not remove removable media, vendor maintenance, supply chain, or insider paths.

4

Learners often treat every tradeoff as a reason to choose the most secure-sounding option. The correction is to match the answer to the stated constraint. Another common confusion is risk transference versus risk elimination.
