HOW DIGITAL TRANSFORMATION STRETCHES NETWORK PERFORMANCE AND RISKS NETWORK
SECURITY


BY CARLOS FERRO, SVP AND GENERAL MANAGER INTERNATIONAL REGION, FOR LIVEACTION.

 * 3 months ago Posted in

Disruption is one of the modern world’s favorite words. Not a day goes by in
which one exciting new startup or another doesn't claim that it will “disrupt”
one space or another.


But take that word seriously and you’ll find that disruption doesn't just refer
to insurgent new ideas or transformational new technologies, but the old
relied-upon traditions and ways of working being fundamentally uprooted.

The double edge sword of digital transformation

Many businesses are now waking up to this reality. Digital transformation is
happening everywhere and often at breakneck pace and while those digital
transformations often provide astounding benefits, they undo the time tested
arrangements upon which those organisations previously relied. Both NetOps and
SecOps teams know this well because digital transformation disrupts their
ability to ensure network performance and spot threats.

So while digital transformations offer huge benefits - they often create chaos
in their wake. However, the true disruptions that digital transformation causes
are not explicitly to do with the new technologies that are introduced, but the
fact that many organisations don’t re-architect their environments to
accommodate the ways in which that technology has changed it.

SecOps’ new blindness

One of the key obstacles that digital transformation often introduces is the
presence of new areas of darkspace - parts of the network that are invisible to
operations and security teams. In fact, one report by Dimensional Research shows
that 81% of operations professionals deal with network blindspots. That’s
understandable - much of the network is now made of devices, services, entities
and technologies which sit outside the perimeter and the view of legacy
visibility tools.

The new shape of the digitally transformed network often makes it difficult to
monitor in the same way. As new technologies are added to the network, new
pathways can open up which lead to unaccounted for blindspots. Similarly, the
ease and flexibility that so often characterises digital transformation can
permit instances of shadow IT and risky behaviours which are also left
unmonitored.

Take an example like the cloud: Many organisations have now migrated their
networks - or portions of the networks - en masse to the cloud. This has, on one
hand, permitted great levels of flexibility for organisations and paved the way
for future transformation - such as mass remote work. On the other, it has made
much of the network invisible to operations and security teams. As a result,
cloud misconfigurations are one of the leading vectors in data leaks.

Similarly, APIs are allowing new connections and collaboration between different
organisations and entities. In fact, it is now estimated that APIs now account
for 84% of

network traffic. Unfortunately APIs are often left unmonitored due to how
quickly they can be spun up, and how numerous they soon become.

As a result, breaches can quickly spiral out of control. One 2022 Google
Research report found that 62% of IT decision makers had experienced an API
related security incident in the previous 12 months. One respondent noted that
“the rate at which APIs are developed today exceeds the rate at which our
organisation can ensure the security of each of these APIs.”

NetOps’ new resource demands

Similarly, when new devices and technologies are added to a network, they can
claim unexpected amounts of resources if not correctly accommodated. This in
turn, has a huge effect on the network and when resources aren’t correctly
allocated to individual parts of the network, performance suffers and
bottlenecks emerge.

The first and perhaps most obvious effect on network performance is increased
traffic. As new technologies, devices and applications get added and new
pathways run through the network, they generate more traffic in more places -
adding to potential complexity, potential performance issues bottlenecks and
ultimately the burden that NetOps teams have to deal with.

These often include bandwidth-intensive applications - such as video
applications - which can be extremely demanding on network resources. When these
new demands aren’t accounted for, they can deprive other parts of the network -
including critical applications - of crucial resources thus leading to more
performance issues and introducing latency.

The potential issues run further still: Cloud deployments, hybrid networks and
other distributed architectures can introduce latency; integrating new
technologies with legacy technologies can cause compatibility problems which can
cause further performance issues and initiatives such as remote work can cause
huge problems if they’re not properly optimised and endowed with the correct
resources.

So what?

While enterprises undergo digital transformations, they often expand out of the
reach and sight of the NetOps and SecOps teams that are supposed to be managing
the network. As the network complexifies and their monitoring tools become less
effective, problems spiral and those organisations become sure victims of
security incidents and have to deal with more and more performance problems and
ultimately, downtime.

Downtime is a very scary word for a business. Considering that so many
businesses are internationally-focused and digital-first, they require the
smooth operation of their networks every minute of every day in all timezones,
everywhere. Every minute of downtime is a minute of revenue loss, increased cost
and business paralysis. In fact, data shows that downtime costs organisations
$300,000 to $400,000 an hour.

Treating the problem

Many of the network optimisation problems that come along with digital
transformations are not necessarily problems of the technologies themselves, but
that organisations haven’t pre-empted the ways in which they would disrupt their
previous modes of operation.

Organisations can’t always be expected to know what these digital
transformations will do to their networks. Networks are complex things and are
becoming ever more complex so it may not be easy to understand beforehand the
true scope of the changes that a digital transformation will make to the
network.

That’s one of the reasons it's so important to regain control and visibility
over the network to accommodate digital transformations as and when they happen.

The complexification of the enterprise network that digital transformation
introduces increases the machine-to-machine traffic within the data center which
is often invisible to IT teams. Retaining visibility and control over the
network requires visibility into this crucial east-west channel. That solution
should include the ability to glean granular insights to quickly identify,
troubleshoot and resolve issues across both the traditional network and virtual
infrastructure.

Digital transformation offers incredible possibilities for businesses, but
they’re highly disruptive too. Organisations need to maintain visibility into
their own network so they can actually understand the ways in which digital
transformations fundamentally change the network.
