Static filtering rules that are created based on network-layer characteristics
TCP replay attack filtering rules that are dynamically generated

• Defense against application-layer attacks (HTTP)

Defense against high-frequency application-layer attacks (HTTP and HTTP CC attacks) based on behavior analysis
Defense against low-frequency application-layer attacks (HTTP and HTTP CC attacks) based on machine learning
Defense against slow-rate HTTP attacks based on behavior analysis, including HTTP slow header, HTTP slow post, RUDY, LOIC, HTTP multi-methods, HTTP Range request amplification, and HTTP null connection attacks

• Defense against HTTPS/TLS encrypted application-layer attacks

Defense against high-frequency HTTPS/TLS encrypted attacks

• Defense against application-layer attacks (SIP)

Defense against SIP flood/SIP methods flood attacks, including Register, Deregistration, Authentication, and Call flood attacks
Source-based rate limiting

• User-defined filtering rules

User-defined filtering rules for local software and hardware, as well as BGP FlowSpec rules for remote filtering. The fields can be customized, including source/destination IP address, packet length, IP protocol, IP payload, source/destination port, TCP flag bit, TCP payload, UDP payload, ICMP payload, DNS domain name, HTTP URI, HTTP field user-agent, as well as caller and callee in the SIP protocol.

IPv4/IPv6 dual-stack defense against DDoS attacks

• Automatic tuning of defense policies

Attack traffic snapshot, defense effect evaluation, and automatic tuning of defense policies
Automatic attack evidence collection

• Baseline learning

Support for dynamic traffic baseline learning and learning period configuration

• Packet capture-based evidence collection

Automatic packet capture based on attack events and user-defined ACLs for packet capture
Online parsing and analysis, source tracing, and local analysis after downloading for captured packets
