The Zero Trust Model is exactly what it sounds like. A model that indicates that organizations must place zero trust into anything inside or outside their perimeters. Essentially, its motto is “Don't trust anyone.

2. Zero Trust
Model
The Zero Trust Model does
not trust anyone from
within or outside of the
company. Hence, one of its
main principles is to ensure
verified authentication and
access to all organizational
resources
User access must be limited to
allow them access only to the
resources they need to do their
job. By limiting each user's
access, you can limit attackers
from gaining access to all
resources of the organization
with a single compromised
account.
Another aspect of the Zero
Trust Model, which also
aligns with several security
compliances is logging. The
model’s definition implies
that everything ranging
from network calls, access
requests, file access, email,
etc.

3. The
Architecture of
the Zero Trust
Model
One of the most important
aspects of the Zero Trust
Model is the data. Since data
is the main target for an
insider as well as outsider
attackers, it is the most
important part of the Zero
Trust architecture that must
be secured.
Networks are used to
steal data, hence this is
another component
that must be
segmented, isolated,
and restricted with
firewalls.
Since people are the
weakest link in security,
they must be monitored,
limited and their access
should be managed strictly.
People should not be
trusted in the Zero Trust
Model and must be verified
and checked at all available
instances.

4. How to Deploy the Zero
Trust Model?
Following the Zero Trust Model is not
about deploying policies and creating
architecture once, but it is about
constant monitoring, maintaining,
and updating the model as time
passes. Make sure to identify new
sensitive aspects of the
infrastructure, update policies
according to the new transaction
flows, and maintain the Zero Trust
environment at all costs.
Map how user access takes place, how
the workflow occurs, and what can be
done to ensure that the Zero Trust
Model is incorporated into the generic
system workflow.Create well-written
policy documents that incorporate all
the Zero Trust Model principles.
