Discussion

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.

Check Content

The reviewer will, with the assistance of the IAO/NSO, verify 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.

Fix Text

Develop a plan to identify all services and protocols needed by each port in the SAN, modify the routing lists to enforce a Deny-by-Default policy and allow only the identified services and protocols on each port that requires them.  Obtain CM approval for the plan and implement the plan.
