Today's focus: Architectural approach to security on the rise
By Scott Crawford
Because it is constantly evolving, the IT security market is
crowded with a mind-boggling range of technologies and tools. An
enterprise's ability to adopt new technologies is often limited
by the management challenge posed by the scope and variety of
options. This, however, has resulted in an opportunity for
security vendors - by enabling them to promote security
architectures.
The "architectural" approach to security refers to the
integration of disparate but complementary security tools into a
managed whole. From the Trusted Computing Group's Trusted
Network Connect initiative, to Sourcefire's "3D" suite, security
architectures integrate a risk intelligence center with a
combination of defenses and proactive risk management such as
patch and software maintenance, all strategically deployed and
interfacing with enterprise authentication services. This
holistic approach enables IT to more fully realize the benefits
expected from the use of many available options.
Infrastructure vendors have been among the most vocal proponents
of the approach, as evidenced by Cisco's Network Admission
Control (NAC) effort. More recently, these same vendors have
begun to drive "up the stack" with an architectural approach to
application infrastructure, as with Cisco's new Application
Oriented Networking (AON) initiative. The reasons are clear:
enterprise and Web applications, like security systems, require
the integration of moving parts into a coherent whole. This is
an approach that lends itself to infrastructure, so the fit has
much resonance in the market.
There would appear to be synergy between the architectural
approach to security and the emergence of integrated application
architectures. Yet up to now, the application security market -
the ground on which these trends would be expected to converge -
has been characterized by products that tend to be
point-centered rather than architecturally oriented, such as
application firewalls.
That is changing as we begin to see Web application security
products that more closely reflect the architectural nature of
enterprise applications themselves. Breach Security, for
example, is a vendor with a new class of application security
products that can monitor application traffic and distribute
security controls to key points throughout the application
architecture. This differs from point-oriented inline
protections, in that monitoring and control can be separated and
distributed across an application architecture itself, rather
than depending on a single inline security enforcement point.
This does not mean that application security enforcement points
disappear, any more than network firewalls have disappeared -
far from it, as the intelligence and performance of application
security point systems is very much needed at key points in the
application architecture. Rather, it focuses on the distribution
of control to the application components where it makes the most
sense, enabling controls integral to network systems,
application platforms, Web servers and databases, all to be
called upon to enforce application security both proactively as
well as in reacting to a detected threat. This leverages the
security capabilities of application components themselves,
distributing risk management beyond single enforcement points.
Architecturally oriented security is becoming an increasingly
common message - but application architectures would appear to
be a most fertile green field for this approach. The complexity
of Web and enterprise applications means that their security
lends itself to the management model of centralized intelligence
with distributed control. Expect to hear more about vendors such
as Breach Security and the emerging field of architecturally
oriented application security in the not-too-distant future.
