Su22 - CPS 401 - Defensive Security
The Zero Trust model is built upon the following
5 assumptions:
• The network is always assumed to be
hostile
●
5G UC 83%
• External and internal threats exist on the
network at all times
• The location of the network is not enough
for determining trust in the network
Every device, user, network and workflow
is authenticated and authorized
• Policies must be dynamic and uniquely
calculated from all possible sources of data
1. Why is the assumption that the network
and all its elements are hostile a key tenet
of the Zero Trust Architecture?
2. Discuss the concept that the Zero Trust
approach assumes that all Networks are
"Hostile" and "Dangerous" at all times.
3. Based on your current job and experience
in Cybersecurity, why is it required that
every user, every device, network
components and workflow must be
properly authenticated and authorized?
Explain what you think we need to stop
doing, as defenders, to apply this concept
into the enterprise to make it more secure?
4. Another key tenet of Zero Trust is that trust
should never be granted implicitly and that
any trust given needs to be constantly
evaluated. Discuss this concept and explain
the value and the pros and cons associated
with this approach.
