ith the increased
adoption of cloud
services, SD-WAN
adoption is booming thereby
reducing the use of traditional
corporate network models.
SD-WAN offers the promise
of lower capital expenditures
and cut an organisation’s
ongoing operational and
management costs by around
a half when compared to the
traditional hardware-based
approaches. It also boosts up
the network efficiency.
However, there is one area
where SD-WAN is deficient
in, i.e. advanced security
functionality. According to a
statement from the research
firm Gartner most of the
SD-WAN vendors support
basic capabilities such as
stateful firewalling and
VPN, but they still have to
depend on security partners
for advanced functionalities
such as intrusion prevention
system, malware analysis
and sandboxing. For that, it
recommends organisations
to deploy integrated and
dynamic threat protection for
multiple cloud connections
at the cloud’s edge and
the customer’s Internet/
WAN gateway points. Let’s
take a look at the widely
recognised security pitfalls
that pose a threat for SD-WAN
deployments.
Leaving Traffic
without Inspection
Sometimes, users don’t
have any idea about the
configuration of their
networks. As a result, the
internet-bound traffic that
leaves directly from satellite
offices in certain SD-WAN
architectures is not inspected.
In many other cases, it so
happens that the traffic is
intentionally let to leave
without any sort of inspection
