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 embedded systems

Embedded systems are used within OT environments. They are a combination of hardware and software, designed to operate a particular operational process. Machine tools used in mechanical engineering environments would be a good example of where we might see embedded systems, but we can see these systems in almost all environments where industrial controls are used. They will be used in power stations, water treatment plants, transportation systems, and much more. Embedded systems may rely on hardware that was designed over 50 years ago, and the software may have been written in low-level machine code.

In many cases, there is no cost-effective way to upgrade a legacy embedded system. It may be operating a nuclear facility or a coal-fired power station that is due to be decommissioned in the near future. Network segmentation is often the only way to mitigate risks when supporting these environments.
