摘要: This paper defines a methodology for the evaluation of Rate-based Intrusion Prevention System (IPS) Distributed Denial Service (DDoS) threat. system uses realistic background traffic along with attacking traffic, four different DDoS attacks. The metrics are defined using Snort for: rate packet loss; time to respond; available bandwidth; latency; reliability; CPU loading; and memory usage. results show that is effective in handling low-throughput attack, but when 6 000 pps malicious reached, starts drop legitimate packets, at same loss. It also shows IPS operates well up throughputs 1Mbps.
