A Focused Approach to Zero Trust

The evolution of IT has greatly outpaced that of
cybersecurity. While security hasn’t stood still, it hasn’t progressed effectively
to address today’s digital and gig economy realities. Here are some reasons why
this is so.

IT is distributed, hybrid and on-demand, broadening the
scope of your attack surface. The workforce, like today’s data, is mobile, and
access can come from anywhere. Complexity
is rampant
, putting your security team under immense pressure to protect
data wherever it is, be it on premise, in the cloud, or elsewhere. Finally, threats
are pervasive and constantly evolving. Your defenses need to evolve as well.

Security must undergo a Zero Trust paradigm shift, which Forrester
defines as “a fundamental transformation of corporate security from a failed
perimeter-centric approach” – Security Architecture &
Operations Playbook,  Forrester, 2018.

In-order to achieve Zero Trust, focus is imperative. It requires
addressing three fundamental challenges to become cyber resilient, which can minimize
complexity and establish a secure foundation for your future.

  1. Reduce Your Attack Surface

There are too many entry points and paths leading to your critical systems.
You need to make resources, wherever they reside, invisible to unauthorized
people. It also requires limiting the lateral movement an individual can take
once access has been granted.

This is all achievable with a Software-Defined
that cloaks the ports of entry and deploys fine-grained
microsegmentation for a secure 1:1 connection to permitted resources. Zero
Trust terminology calls it the Principle of Least Privilege.

  • Secure User Access 

Zero Trust requires replacing the old “trust, then verify” model with
an identity-centric approach that factors in context before granting secure
access. Gone are the days when a known IP address and password are enough to
ensure the user behind the device is who she says she is.  

Attempting to achieve Zero Trust by gluing together VPNs, NACs and various
types of Firewalls introduces unneeded complexity. A Software-Defined Perimeter
presents a better approach to network security that embodies the principles of
Zero Trust, reduces operational complexity and unifies secure access across
your hybrid organization.

  • Neutralizing

Leon Trotsky said it best, “You may not be
interested in war, but war is interested in you.” Threat mitigation requires both
a strong offense and defense.

Your frontline consists of your employees and
the online environments they access. Adversaries actively prey on your
workforce here. You must monitor
your digital footprint to proactively detect and remove threats

before they reach your workforce

Being complacent in today’s threat ridden world
will end in disaster. Organizations must continuously search for
vulnerabilities and hunt for threats that have bypassed preventative controls. Cyber
resilience requires deep analytics and specialized expertise to unearth where
you are most vulnerable and how an adversary could get in.  

Security needs to
catch up with IT
and a focused
approach to Zero Trust
can get you there. By embracing this
straightforward framework, organizations can become more secure and less
complex. Learn more about a focused
approach to Zero Trust.
