Introduction
This chapter covers objective one of Domain 3.0 Security Architecture of the CompTIA Security+ 701 exam.
In this chapter, we will review the architecture and types of infrastructure that organizations use, from the cloud to on-premises infrastructure. This will include an exploration of centralized and decentralized models, as well as additional functions such as virtualization, embedded systems, high availability, and other considerations.
The final sections will also examine several network infrastructure security methods, such as software-defined networks, physical isolation, and logical segmentation, which are designed to minimize the impact of potential attacks.
This chapter will give you an overview of why companies rely on these processes to keep their environment safe to ensure you are prepared to successfully answer all exam questions related to these concepts for your certification.
