Now that the pandemic appears to be receding from crisis
levels, there is a clear push to return to normal in the workplace. But while
many organizations are pulling back from the full work-from-home model that
arose during the contagion, this is unlikely to result in a complete return to
the workplace.
Instead, a new hybrid model is emerging in which workers
divide their time between home and office to varying degrees. Perhaps more significant, however, is the fact
that for the most part productivity remained consistent, or even improved,
thanks to new generations of remote collaboration tools.
Safe and Secure
But this new model of working is not without its challenges,
particularly in areas like data protection and security. When workers are no
longer connecting to enterprise data from within the firewall, new measures
must be taken in order to maintain existing security and compliance
requirements.
Chief among these are Zero-Trust access and Secure Access
Service Edge (SASE) architectures. Working in tandem, these two approaches
offer the best protection for distributed IT environments while also
accelerating digital transformation and the implementation of cloud-first
infrastructure.
The key to their effectiveness lies in the way they both
address two key issues in a coordinated fashion. Zero-Trust allows security
policies to extend all the way to the user device rather than simply the data
environment in general. Using multi-factor authentication and other tools,
Zero-Trust allows access to be established using multiple pre-set parameters,
such as data, time, location and device. This allows continuous security
controls to be maintained within and outside a traditional firewall, basically
embedding them into workloads wherever they go.
Meanwhile, SASE works to minimize the friction between
network and security protocols that arise as the enterprise data footprint
becomes increasingly dependent on cloud infrastructure. This provides uniform protection
across the entire data footprint, integrating Zero-Trust with other security
measures like secure web gateways and cloud access security brokers.
This greatly simplifies the security management burdens for
the IT staff and allows them to build and deploy policies based on the
applications that provide the most optimal user experience. In fact, under this
architecture, users are able to access applications directly, so as not to
expose the enterprise network to attack. At the same time, this eliminates much
of the backhaul traffic that adds latency to the network as it encounters
centralized network security controls.
For a hybrid workforce to maintain peak productivity, this
is essential, particularly when knowledge workers become reliant on globally
distributed architectures. One key capability is the power to microsegment
enterprise IT assets using remote policies. This provides real-time access on
an as-needed basis, while also reducing the time spent fixing trouble tickets
and increasing the ability to optimize resources for digital transformation.
Network Simplicity
Equally important is the way SASE streamlines overall
network architectures. Once in place, SASE allows the enterprise to do away
with costly on-premises solutions like firewall, proxy and VPN gateways, and it
greatly simplifies WAN and MPLS deployments. This enhances the speed at which
new network architectures can be established and heightens the flexibility to
customize them for peak operational performance for both general-purpose and
highly specialized applications.
As the digital economy evolves, organizations will be tasked
with providing the highest levels of data access to the workforce in order to
extract the greatest value from data, infrastructure and individuals. But
without the proper security and compliance tools, this will all be in vain
since the economic costs of data theft and malware is incalculable - both in
terms of direct financial loss and the loss of brand trust and credibility.
Implementing Zero-Trust and SASE puts the enterprise on a
secure footing as it transitions into a cloud-first, digitally focused entity,
but this heightened security cannot be treated as an afterthought as security
measures were in previous generations. It must be incorporated into this new
environment right from the start, as a core asset.
In this way, organizations will know that their data and
resources remain protected no matter where the workforce is located.
