Transmission Control Protocol/Internet Protocol is the foundational communication protocol suite for the internet. TCP breaks data into packets, ensures reliable delivery, and reassembles them at the destination. IP handles addressing and routing packets between networks.
Every cybersecurity role requires TCP/IP knowledge. SOC analysts examine packet headers daily when investigating alerts. Penetration testers exploit protocol weaknesses to move through networks. Understanding TCP flags, handshakes, and IP addressing is non-negotiable for any technical security position.
