Ensure routing tables for VPC peering are "least access"

SrednjaNivo 1Ručni pregledalibaba

Opis

Once a VPC peering connection is established, routing tables must be updated to establish any connections between the peered VPCs. These routes can be as specific as desired, even peering a VPC to only a single host on the other side of the connection. Although the routing table is empty by default upon creation for any newly created routing table, hence it denies any default access, it is recommended that the table entry is only added based on the least access ... Reported as a manual review item: the benchmark audit needs console review or organisational judgement.
