Introduction
The Security+ certification is a professional certification offered by CompTIA (Computing Technology Industry Association). It validates the knowledge and skills required to secure computer systems and networks, making it a widely recognized certification in the field of information security.
The Security+ certification is intended for IT professionals, including security administrators, network administrators, system administrators, security consultants, and security engineers. It provides a baseline level of knowledge and skills required for securing networks, systems, and applications in an enterprise environment.
The Security+ certification is widely recognized by the industry and is recommended or required by various organizations, including the US Department of Defense (DoD) and several private companies. It is also considered a stepping stone for more advanced cybersecurity certifications, such as the Certified Information Systems Security Professional (CISSP) or Certified Ethical Hacker (CEH).
