Set up the ec2 integration.
Reduce the probability of a breach by checking EC2 security groups for inbound rules that allow unfettered access to host using the Internet Control Message Protocol (ICMP), a protocol commonly used to troubleshoot TCP/IP networks and deliver IP packets, and restrict access.
Malicious activity, such as denial-of-service (DoS) attacks and Smurf/Fraggle attacks, can occur when permitting unfettered access to this port.
Follow the Security group rules docs to learn how to restrict access to host using the ICMP.
Run describe-security-groups with a filter to expose security groups that allow access to host using ICMP.
describe-security-group.sh
aws ec2 describe-security-groups
--filters Name=ip-permission.protocol,Values=icmp Name=ip-permission.cidr,Values='192.0.2.0/24'
--query 'SecurityGroups[*].{Name:GroupName}'
