Linux Makes Automation, Infrastructure Strides
The Power of Tux

There is an interesting irony in the technology that surrounds
us. Tools that have been built by the human race are so advanced that
they are no longer able to be controlled and operated by those same
bipedal creatures with the cool opposable thumbs. One company is
introducing some new technology that will let Linux handle these
enormous and complex tasks.
A lot of technology has become bigger than us, it seems. We could not
manually operate the thousands of different switches it takes to
establish a phone call to our Uncle Poindexter in Bippus,
Indiana. We could not manually tune the satellite dish
frequencies necessary to bring in the latest episode of Six Feet Under
bouncing off a piece of metal hundreds of miles over our head. It's
simply too much to handle.
None of this is news to many of us, but it is not something we think
about on a daily basis. We turn the light on and expect the power to
be there. Seldom is much thought given to how that power gets
there. Unless you work for the power company. Or the company that
designs the software running on the power company's computers.
This, then, brings us to Verano, a Boston-based firm who's line of
products is the kind of software that will manage the automation
processes for manufacturing plants and utility companies in North
America and Europe. This is a specialized kind of automation that must
deal with controlling processes in real-time while (ideally) letting
the enterprise side of the company have access to the data so that
financial and business planning decisions can be formulated.
Verano has a lot of experience in this area, having produced software
for commercial UNIX platforms to run in such corporations as Innogy,
which manages 78 percent of the power needs for the United Kingdom.
This is done with Verano's SCADA (Supervisory Control and Data
Acquisition) platform, which allows plant managers, control workers,
and company executives to fully access exactly what data and controls
they need to keep all of the business humming along.
With this legacy fully in place, Verano has recently made the
announcement that they have moved their SCADA software over to the
Linux platform, which makes this the first time Linux has ever been
used for such complex automation processes.
According to Pan Kamal, Verano's new product, Performux, is geared to run on
Red Hat Advanced Server, and now opens the option of using Intel-based
servers to run SCADA-type operations. Kamal, vice president of
marketing at Verano, said that Performux is a
natural progression for many of Verano's customers, since much of
their control software runs on UNIX already.
Using Linux as part of the process control of an automated plant also
allows even better process integration with the rest of the company,
since, unlike UNIXes, Linux can be run on middle-tier and client
machines.
"Now they can run some applications off of the big iron and on
commodity-class Intel servers," Kamal said.
Using Linux also fits in with Verano's Instant Awareness philosophy,
which uses some of the same technology found in instant messaging
protocols to get information in an automated plant out to the people
who need it.
Linux's security and stability, Kamal said, also make it a suitable
candidate to move into this space. It's ability to interface with
legacy plant devices certainly does not hurt either. Nor does the
price tag--Performux comes in at 15 percent lower than Verano's
UNIX-based software.
Kamal revealed that this will not be a one-shot Linux product for Verano.
Performux is itself a highly secure product, but there are some
companies where security is more paramount than others. After the
September 11 attacks, many infrastructure facilities became aware that
they could be potential targets of outside attack.
While these facilities--dams, power plants, water treatment
plants--upgraded their physical security, their managers were also
painfully aware that a computer-based attack could render these
facilities as useless as any bomb could.
For this special class of facility, Verano is planning the
introduction of a new product this week during the LinuxWorld Expo:
the Linux-based Secure SCADA.
Much of the technology of Secure SCADA is the same software code found
in Performux, but what Verano did was harden the underlying Red Hat
Linux code with the National Security Agency's SE Linux
extensions. After this Linux base was integrated with the rest of the
Performux code, Secure SCADA was then further hardened with Verano's
own security features, such as a comprehensive security console.
In many of these types of facilities, there is oft-times a security
gap between the process-control network and the corporate LAN. Kamal
explained that Secure SCADA is the best wedge to place within this
gap, since this hardened software would prevent any cyber-intruder
from coming in through this gaps.
Secure SCADA, like Performux, is a unique offering for these kinds of
facilities, and not just because it is Linux-based, Kamal explained. The
idea of allowing flexible thin-client control over all of a facility's
processes while maintaining such a high level of security is another
aspect of its unique nature.
"No one else is doing this," he said.
Given the success Linux has had in other IT arenas, it is doubtful
that this will remain the only example of Linux in high-end automation and
infrastructure for long.
