This chapter describes concerns for security administrators
of clustered systems. Clustered systems refer
to those systems using hardware and software that permit sharing
of disks, resources, and a common operating system among various
computers. Clusters of VAX processors are said to be joined in an
OpenVMS cluster environment; whereas clusters including both Alpha
processors and VAX processors are said to be joined in an OpenVMS
Cluster environment. To properly secure your cluster, you should
be familiar with the information in the HP OpenVMS Cluster
Systems Manual.
The HP OpenVMS Cluster Systems Manual describes
the tasks of the cluster manager. The cluster manager's job is the
same as that of any system manager, but the cluster manager has
to implement changes across many nodes. The security administrator
for a cluster generally requires the same training and skills as
a cluster manager, and at some cluster sites, the same person serves
in the role of security administrator as well as cluster manager.
At other sites, there may be one or more security administrators
in addition to a cluster management team.
When a site
separates the security administrator function from the cluster management
function, coordination, cooperation, and communication between these
functions becomes vital. As in previous chapters, this chapter uses
the title of security administrator to refer to individuals who
have the responsibility for system security, regardless of what
other responsibilities they hold.
