CompTIA CASP+ CAS-004 Certification Guide

By: Mark Birch

Overview of this book

CompTIA Advanced Security Practitioner (CASP+) ensures that security practitioners stay on top of the ever-changing security landscape. The CompTIA CASP+ CAS-004 Certification Guide offers complete, up-to-date coverage of the CompTIA CAS-004 exam so you can take it with confidence, fully equipped to pass on the first attempt. Written in a clear, succinct way with self-assessment questions, exam tips, and mock exams with detailed explanations, this book covers security architecture, security operations, security engineering, cryptography, governance, risk, and compliance. You'll begin by developing the skills to architect, engineer, integrate, and implement secure solutions across complex environments to support a resilient enterprise. Moving on, you'll discover how to monitor and detect security incidents, implement incident response, and use automation to proactively support ongoing security operations. The book also shows you how to apply security practices in the cloud, on-premises, to endpoints, and to mobile infrastructure. Finally, you'll understand the impact of governance, risk, and compliance requirements throughout the enterprise. By the end of this CASP study guide, you'll have covered everything you need to pass the CompTIA CASP+ CAS-004 certification exam and have a handy reference guide.

Understanding ICS/SCADA

There are many examples of OTs that are deployed to automate the delivery of industrial processes and critical infrastructure. ICS are deployed within manufacturing and process control environments. They allow production lines to run and chemicals to be processed and delivered at the correct flow rates. It is important that information in the form of telemetry is displayed on management systems. There are many components required to manage complex processing environments. Figure 10.2 shows the components of a SCADA system:

Figure 10.2 – SCADA system

Human-machine interfaces (HMIs) allow supervisors to oversee and control complex ICS from a control room or data center. Supervisory computing systems communicate with specialized hardware (programmable logic controllers, or PLCs) that receive information, such as telemetry, from pumps, actuators, and sensors. The plant and equipment can then be automatically controlled by the PLC...
