Network Applications and TCP/IP Security

This course covers the application-layer protocols and services that run on top of TCP/IP and the security mechanisms that protect them. Covering approximately 4 hours and 19 minutes of expert instruction across network services, application protocols, and TCP/IP security, learners develop the skills to configure and secure the services that users depend on daily. Learners benefit by understanding DNS, DHCP, NTP, email protocols, web services, file transfer protocols, and how to secure network communications using firewalls, access control lists, and secure protocol alternatives. online labs reinforce service configuration and security implementation tasks. By the end of this course, learners will be able to configure common network services, implement TCP/IP security controls, and explain how application-layer protocols operate in enterprise networks.
