Traffic management becomes critical as your network
infrastructure expands to support different types of traffic and
users. Most traffic management solutions have serious
limitations: too expensive, difficult to use, and overly taxing
on bandwidth. However ProCurve Networking by HP addresses these
requirements, overcomes the limitations of other solutions, and
gives you valuable insight into LAN performance. Click here to

Today's focus: The good and bad about static vs. virtual
directories
By Dave Kearns
Two weeks ago, I highlighted Bridgestream Vice President of
Marketing Ed Zou talking about the need for business analysis to
create the roles needed for role-based access control (RBAC).
Then, last week, I added Ron Rymon, founder of Eurekify's
thoughts on why role mining of your existing privilege
infrastructure was important. Now you've seen both sides of the
coin, which, as I mentioned last week, I'm willing to bet has
more than two sides - many more.
Symlabs is in the virtual directory business and its Vice
President Felix Gaehtgens was quick to point out to me that the
technology of virtual directories could obviate - or at least
lessen - the need for structuring roles. Not that the concept of
roles is bad - any time we can group similar things together and
treat them as a group or a class it's that much easier to
accomplish a goal. But Gaehtgens likened the virtual directory
(vis-à-vis a static datastore) to a relational database
(vis-à-vis a flat file database).
Gaehtgens said: "Look at what views, triggers and stored
procedure did to relational databases. Virtual directories do
the same for directories, although it's been taking a while for
many folks to appreciate that fact." I'm sure that's a sentiment
that the folks at Radiant Logic, MaXware and Octetstring would
also express.
Gaehtgens believes in the theory of roles, just not the current
practice: "Whenever I hear people talking about RBAC, groups,
roles, and how to use these tools to create a policy model for
access in their organization, I sometimes think they are trying
to fix a sophisticated piece of machinery with a hammer, instead
of taking a screwdriver. Sure, you can do a lot of nice things
with dynamic groups or roles. But then again, that really starts
to creak as your directory grows." It is true that scalability
is sometimes overlooked when we're planning an identity
management project. What works in the lab, and on the testbed
may not perform as well when it's rolled out to the enterprise.
There is a certain flexibility offered by a virtual directory
that a static datastore cannot offer. On the other hand, there's
a certain stability to a datastore constructed on a robust
relational database. You need to establish your own priorities -
but be sure to do that first. Then you can pick the tools that
best meet your needs. Maybe it's a hammer, maybe it's a
screwdriver - just be sure you know the difference.

IS IT THE NETWORK OR THE STORAGE THAT'S THE PROBLEM?
Midsize and larger businesses often find their IT topology has
become a complex mix of servers, networks and storage systems.
Many of these companies also route long-haul traffic over
fiber-based networks - metropolitan-area networks, WANs and
private optical networks. Who's responsible when a
storage-related problem occurs on a fiber network? For more,
