SCTP is a packet-based transport protocol. SCTP provide reliable and secure transport, minimized end-to-end delay, short failover time in case of network failures and both sequence and no-sequence transport. Configuration Overview You should configure at least one SCTP profile to enable the security device to perform stateful inspection on all SCTP traffic. The stateful inspection of SCTP traffic will drop some anomalous SCTP packets. The SCTP firewall supports deeper inspection: • Packet filtering-The profile configuration of drop packets for special SCTP payload protocol and M3UA service enables packet filtering. • Limit-rate-Controls the packets rate of SCCP in M3UA service. The SCTP deeper inspection requires the following steps: • Creating an SCTP profile • Configuring the filtering and limiting parameters • Binding the SCTP profile to a policy 51
