Protecting  RADIUS Login with IP Shielding

IP shielding involves early-stage rejection of authentication requests originating from IPs with a malicious track record. The IP address track record is determined in real time as a collective effort based on input from participating RADIUS servers. This strategy provides a quick and efficient identification of malicious login attempts, protecting the network against DOS, brute-force, password spray, and MFA fatigue attacks.
