Network security is the practice of protecting and preventing unwelcome access attempts to computer networks. In this course, you'll learn about network hardening techniques and best practices. You'll learn to secure networks and about wireless authentication and authorization features You'll examine remote access methods and security considerations, VPN solutions, and the benefits of using virtual network computing and virtual desktop solutions. You'll learn about remote authentication and authorization considerations and how to implement out-of-band management.
