I am here to help you pass the Security+ exam. You can use me as a resource: contact. I read every email sent to me.
The objectives for the exam can be found here: CompTIA Exam Objectives.
The book I used: CompTIA Security+ All-in-One Exam Guide, Sixth Edition (Exam SY0-601).
The audio tool I used: Professor Messer's youtube videos.
Each link under "Exam Objectives" in the Security + section goes through all of the objectives for the Security+ exam. Each chapter has 5 - 9 sections and each section has terms which the exam will use to test your knowledge of computer security. This website can be used to quickly test your knowledge on each term. It can also be used to quickly review terms that you are weak on without having to jump around a book or a youtube video.
