DescribeStaleSecurityGroups

Describes the stale security group rules for security groups referenced across a VPC peering connection, transit gateway connection, or with a security group VPC association. Rules are stale when they reference a deleted security group. Rules can also be stale if they reference a security group in a peer VPC for which the VPC peering connection has been deleted, across a transit gateway where the transit gateway has been deleted (or the transit gateway security group referencing feature has been disabled), or if a security group VPC association has been disassociated.
