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 asymmetric encryption algorithms

Asymmetric encryption has two main goals – one is to support a secure key exchange/agreement process, while the other is to support non-repudiation through the use of digital signatures. It is not used for bulk encryption as the key sizes (compared to symmetric encryption) are large. This would mean that it could be thousands of times slower to encrypt large amounts of data. Asymmetric encryption uses a key pair that is mathematically related; there is a public key and a private key. You can think of the public key as your bank details that you can share with a customer (who wants to make a payment). Your private key is used to securely access your funds. In this analogy, your bank card + pin + CVC code would be your private key. You would not share your private key with anyone.

Rivest, Shamir, and Adleman (RSA)

RSA is used for secure key exchange and digital signatures. It was developed and published in 1977, so it is one...
