TCP Reset Injection
TCP reset injection attempts to disrupt a connection by causing endpoints to accept forged or unauthorized TCP RST packets.
Mechanism
If an endpoint accepts a reset that appears valid for the connection, the session can terminate unexpectedly.
Indicators to watch
Unexpected RST spikes, repeated resets from an unexpected path, interrupted long-lived sessions, and sequence-number anomalies.
Concept diagram
Defensive controls
Use authenticated/encrypted protocols, network path protection, monitoring, and modern transport/security mechanisms where appropriate.
Recommended security control
Wireshark TCP analysis
Analyze captures from a controlled lab connection.
