I started to study for the CompTIA Security+ in March 2022, after 3 months I received my certification. It's a very great course that helps build the foundation for a great Cybersecurity career. I took an online course through Hacker-Arise (https://www.hackers-arise.com/) with Occupytheweb (OTW) a great Hacker, great Teacher and great Writer of books like : "Linux Basics for Hackers - No Starch Press" and "Getting Started Becoming a Master Hacker - Independently published", I highly recommended. I also studied a book called "CompTIA Security+: SY0-601 Certification Guide Second Edition by Ian Neil - Packt>". This book is very well written and the concepts are described very well. The book covers how to recognize and mitigate attacks, threats and vulnerabilities and how to help organizations respond to a cybersecurity incident. It also helps to manage risk, security and compliance to regulations. Cloud and Wi-Fi security are important chapters in the book because a lot of organizations are transitioning to hybrid networks. The CompTIA Security+ certification validates that you have the core skills necessary for a career in IT security. The exam costs around $370, it consists of 90 multiple choice and performance-based questions. You have 90 minutes to complete the exam. Professor Messer has an entire CompTIA Security+ training course for free on YouTube.
Prepare your brain to memorize a lot of acronyms!!!

I believe that this certificate will help improve your skills and be a great investment for your future career in IT security.
