This is a no-nonsense book designed for people who want to earn certificates in the information security industry. Some of the advice reminds me of emails I get at my place of work, where we receive security tips and are required to complete quizzes to stay on top of things. But this “bible” is way more in depth than that and promises to thoroughly help readers pass their tests on their first try. Topics in this nearly 600-word (e-book version) tome include data integrity and availability, OS security features and patch management, information on malware, social engineering techniques, how to secure network traffic, cloud service models, risk migration strategies, and so much more. I thought the portions covering exam essentials and exam topics were particularly helpful at the end of chapters to really help readers retain what they learned. For example, key things to know for the CompTIA Security+ SY0-701 test include an outstanding grasp of code that is malicious, being able to identify varied types of malware, and a detailed understanding of antivirus software. I consider myself a somewhat techie person, but I have to say I’m glad I don’t have to take any of these tests! An A+ book for its wide range of coverage and intricate details.

I picked this up hoping for a straightforward, all-in-one study resource, and that’s exactly what I got. The CompTIA Bible 3-in-1 doesn’t waste time on fluff or filler; it’s clearly written for people who are serious about certification and want a structured, manageable path through a lot of material. The tone is professional but never dry, and the explanations strike a good balance between depth and accessibility. I never felt lost, even when tackling some of the more technical areas of cybersecurity or networking.

What really helped me was how the book is broken down into digestible sections, each ending with key takeaways, quizzes, and sometimes hands-on labs. That structure made it easier to retain what I was reading, and I could tell the content was aligned with the actual exam objectives. The practice questions were a great bonus. They mirrored the kinds of things I’d expect to see on the real test and helped me identify where I needed to focus more.

Overall I’d recommend this to anyone studying for Security+, A+, or Network+ whether you're brand new to IT or switching fields. It’s a serious book, but it doesn’t try to intimidate.
