I am receiving security exception email every hour since yesterday and the reason is Admin Query String.
When I checked the IP addresses these attacks are not coming from same IP , but it it belongs to same host with different IP addresses as mentioned below.
Host: ec2-35-167-154-190.us-west-2.compute.amazonaws.com
Host: ec2-52-11-54-22.us-west-2.compute.amazonaws.com
Could you please tell me how to block this kind of attacks, if the attacker is using different IP addresses?
Best Regards
