TCP: Transmission Control Protocol in Cybersecurity
TCP stands for Transmission Control Protocol. TCP is a connection-oriented transport protocol that guarantees reliable, ordered delivery of data between hosts. It forms the backbone of most internet communications.
How TCP Is Used in Cybersecurity
Cybersecurity analysts inspect TCP flags and handshake patterns to detect SYN floods, port scans, and other network attacks. SOC teams monitor TCP sessions for anomalous connections to command-and-control servers. Security engineers tune firewall rules based on TCP port and state information.
