Companies can manage IT risks and remain responsive to the marketplace, MIT"s George Westerman tells CIO Insight"s Allan Alter.
CIO INSIGHT: Some businesspeople say overzealousness about IT
security makes it harder to be agile and responsive to the marketplace.
What do you say to them?
WESTERMAN: We hear that, and I actually believed for a long
time that if we put more process, governance and standards in place, we
actually would hurt the agility of the company. But more and more
research that my CISR [MIT Sloan Center for Information Systems
Research] colleagues and I have been doing shows you can actually have
standards, processes and agility. You don"t want to be too Draconian,
but if we have a good solid foundation, a very well built architecture,
and a streamlined yet tight governance process, you can actually have
both security and agility. But typically, when you put a risk
governance process in place, it tends to be much more difficult before
it gets better. It takes a while to work out.
So realistically, expect it will slow you down until you learn to do it better.Absolutely.
And then make sure you are continually improving that process. The idea
is to give people good standards to live by, good policies to follow,
and then allow them to do their thing as long as they"re following
those standards and policies. That allows them to be agile while living
within a reasonable set of rules. For example, when PFPC, a financial
services transaction-processing firm based out of Delaware, first put
their risk governance process in place, they identified 300 supposedly
major risks. That wasn"t useful at all because 300 risks are so many
it"s hard to keep track. It turned out they had a lot of inconsistency.
Two out of seven people involved in the process had identified
two-thirds of the risks. The others may have identified not enough
risks. So they boiled it down to 30 risks. They started understanding,
what does it mean to be a high risk, what does it mean to be something
you would report to corporate as opposed to keeping it in your own
area, how do we report risks in a consistent way. They got down to 18
or 19 relatively high-importance risks. Now, that"s a manageable
number; when the CIO goes to the enterprise risk committee meetings,
he"s got a small number of things he wants to talk about.
Another example of a good risk governance process is [European
telecom company] TeliaSonera. They have a really nice process for doing
internal security audits on new projects and existing applications.
They have tried to make it very much a partnership between IT and
business. They identify issues, and work out who will take care of
them. Then they come back later to see whether the issues have been
addressed. Because they work in partnership—IT does some parts, the
business units do other parts—it"s non-threatening. It"s very much,
let"s manage the risk in this organization, as opposed to, let"s find
all the mistakes you"ve made. This partnership has made the reviews
easier because people feel less threatened. The head of security said
when we come back these risks have all usually been handled; we almost
never have to come back and tell them twice because of the partnership
model they"ve developed.
The last bit I"ve heard that"s really interesting is using the
internal IT auditor center at the beginning of the systems development
process. In many cases internal auditors tend to function almost as an
afterthought—they come in afterward to just kind of bless the system.
But more and more CIOs I"ve been talking to say the best thing they"ve
started to do is put their internal auditors into the initial meetings
of a new application development project. The auditors help them avoid
issues right up front, so when it comes time for a different auditor to
sign off on the system later, the problems aren"t there.
So, yes, people are learning to balance security and agility well,
although we don"t always hear about it. But many people are still
struggling to figure out how to make business aware of security issues
and talk about risk issues in a holistic way, so businesspeople can
make the right investments.
