Practical approaches for MTCP Security

Multi-path TCP (MPTCP) is an emerging IETF standard for providing connection resilience and bandwidth aggregation. MPTCP evolves the existing TCP protocol by allowing multiple TCP flows for a TCP session. This provides exciting new possibilities for mobile devices that can maintain TCP sessions as connection paths are added or dropped, and multi-homed servers that allow TCP sessions to take advantage of a mesh topology. However, current network security monitoring infrastructure solutions cannot appropriately inspect MPTCP connections, leaving significant intrusion detection and data loss blind spots. This paper will discuss practical approaches for MPTCP security.
