1-2-1 Common security risks
System administrators frequently separate production LANs from management LANs. In such
cases, management LANs act as a separate network, which isolates management traffic from a
production network and reduces the risk of security-related threats. If a management controller such
as the SVP exists on a production LAN, the storage subsystems are left open for access by any
entity on the IP network. Whether the access is intentional or not, the resulting security risks can
lead to DoS (Denial of Service) attacks and actual loss of storage availability. DoS attacks may lead
to a management session being hijacked for malicious purposes, such as unbinding a storage
extent from a port during an I/O operation.
The following are guidelines for constructing management LANs:
Traffic from the production LAN should not flow through, or be routed to, the management
LAN.
If possible, all hosts with management interfaces or controllers on the management LAN
should be hardened to their maximum level to reduce the potential that software other than the
management interface will not lead to an exploit of the entire station or device. (In this case
hardening includes removing unnecessary software, shutting down nonessential services, and
updating to the latest patches.)
The management LAN should intersect a production LAN only on those computers acting as
an interface between the management LAN and the production LAN (for example, the Device
Manager server.)
If possible, computers intersecting both a private LAN and a management LAN should be
behind a firewall of some kind, further inhibiting unintended access.
1-2-2 Most secure configuration: separate management
LAN plus firewall
In this case, the computer hosting Device Manager server must either be dual-homed or have two
NICs, and every other management application must be of a similar configuration. The first NIC for
each computer is attached to a LAN dedicated to manage traffic between the management
computer and managed storage subsystems. A second NIC is attached to a LAN where access is
governed by a firewall. As shown in
Figure 1-3, each application server could also be connected to
