Yes and no. Security+ is a very specific subset of training and covers everything you need to know to protect (and access) most computer configurations. specific knowledge of proprietary systems are required to ensure a system that meets the standards of some career paths.
Security+ gives you the initial qualification to apply and work in any of the jobs listed and much more, but it is actually the first step in an ExamTopicsFree ongoing quest to understand cybersecurity. Technology changes all the time. Most employers expect you to know what this certification offers and to understand each system and a career path that requires a little more training and knowledge.
You may need to expand your understanding of computer systems by taking CompTIA A+ if you work in a small office and multitask, or you may need to learn C++ to understand the deep flaws in a system your company runs.
However, you'll never get into those careers if you don't start somewhere like Security+, and many companies will HAPPILY take someone trained in security over someone who isn't.
