Learn the protocols, services, and security mechanisms that run on top of TCP/IP. Through the industry-proven lens of the CompTIA Network+ (N10-009) exam, you'll move across four modules from core protocols such as TCP, UDP, and ICMP and everyday diagnostic tools, through application services including DNS, DHCP, NTP, email, file transfer, and remote access with SSH, to the access control, encryption, and PKI that protect it all. Wireshark packet capture and hands-on online labs, including configuring a DHCP scope and creating DNS records, help you set up and secure the services users depend on every day.
