The SAN fabric zoning lists are not based on a policy of Deny-by-Default with blocks on all services and protocols not required on the given port or by the site.
An XCCDF Rule
Description
By using the Deny-by-Default based policy, any service or protocol not required by a port and overlooked in the zoning list will be denied access. If Deny-by-Default based policy was not used any overlooked service or protocol not required by a port could have access to sensitive data compromising that data. The IAO/NSO will ensure that SAN fabric zoning lists are based on a policy of Deny-by-Default with blocks on all services and protocols not required on the given port or by the site.
