$2.($IDPS Effectiveness$)$

An IDPS $($Intrusion Detection and Prevention System$)$ constantly checks source IP addresses on all incoming packets. If the IDPS finds any source IP address that accounts for more than $20\%$ of incoming traffic over the last $30$ minutes, it immediately blocks all packets from that address for the next $24$ hours. Is this an effective IDPS solution to detect and prevent DoS $($Denial of Service$)$ attacks? Explain in detail.
