How much networking knowledge is needed for cybersecurity?
Basic networking knowledge is needed, but you do not have to begin with advanced expertise. Understanding concepts such as IP addresses, TCP/IP, DNS, HTTP, routing, and firewalls makes it easier to learn how attacks and defenses work. The depth required varies depending on whether you focus on monitoring and analysis, vulnerability assessment, operations, research, or another area, as well as on the courses you take.
