About this course

This course is a critical component of modern technical controls and countermeasures, as many of the technologies covered represent the daily technical activities of security practitioners, operators, and administrators. Begin by discovering various infrastructure security considerations like device placement, security zones, and failure modes. Then, you will compare network appliances and explore port security and firewalls. Next, you will examine virtual private networks (VPNs) and IP security (IPSec). Finally, you will investigate transport layer security (TLS), software-defined wide area networks (SD-WANs), and secure access service edge (SASE). This course is part of a series that prepares you for the CompTIA Security+ (SY0-701) exam.
