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 encryption protocols

Hashing, symmetric, and asymmetric encryption are building blocks that are used to support applications and protocols that need to secure how data is stored and transmitted. Many processes will use a cipher suite, drawing on the strengths of the different types of encryption. We depend on these protocols to protect users when we're accessing online banking, remotely accessing the workplace, protecting information systems when they must be administered across a network, and ensuring that emails that are sent and received can be trusted. We will look at some of these common protocols in the following subsections.

Secure Sockets Layer (SSL)/Transport Layer Security (TLS)

SSL/TLS is used to encrypt many application layer protocols, such as HTTP, SMTP, IMAP, LDAP, and many more. It provides confidentiality (through encryption) and integrity (through HMAC). It uses hybrid cryptography through a suite of protocols. SSL is no longer used as it...
