The Zero Trust Security Model for Modern Businesses!
1. The Zero Trust Security Model for
Modern Businesses!
Introduction:
The network security model has undergone a sea of changes over the years. While
perimeter-based security might have once seemed like a decent solution, users now realize that
leaving their security in the hands of others places them at a greater risk of facing data
breaches. The need for stringent identity verification has been felt for quite some time.
2. Zero Trust is an approach to securing networks that focuses on rigorous verification and user
authentication. Instead of focusing on just preventing hackers from gaining access, Zero Trust
ensures that every user and device accessing the network is authorized and authenticated. The
network and systems inside it get protected only after authentication has been performed for
each user or device attempting to connect.
What is Zero-Trust Security?
Zero-trust models are based on the idea that all users, including those with privileged access,
should be considered untrustworthy. This concept stems from a traditional security model in
which networks are divided into zones, and users have varying access levels depending on their
location in the network. Firewalls protected network resources, and permissions were granted
based on user identity, location, and activities within the network.
More recently, however, zero trust has gained popularity as a way to protect against
cyberattacks that target privileged users. As such, this whitepaper will discuss the fundamental
elements of zero trust security and why it is necessary for safeguarding networks against
today's sophisticated cybercriminals.
Since the Zero Trust model does not rely on the perimeter to safeguard data, it is becoming one
of the hottest topics in security discussions today.
The Zero Trust security model replaces the perimeter-centric security architecture and ensures
that access and security decisions are enforced dynamically on user context, identity, and
device. Instead of focusing on a single network, this model lessens the perimeter that can be
effective around every asset, device, and user. It works on the principle of not trusting anyone,
not allowing access to IP addresses and machines to anyone without knowing their identity, and
verifying whether they are authorized to gain access; it also protects users and applications
from advanced cyber threats.
3 Tips For Getting Started With Zero Trust Network Security:
1. Identify the protected surface:
It is becoming increasingly difficult to reduce, shrink, or defend the attack surface in today’s
environment. Thus, start by aiming for the micro level of the attack surface instead of the macro
level. Zero in on what is most crucial for your organization, for example, sensitive data, assets,
applications, and services (DAAS). Then build a perimeter around these critical assets to ensure
that controls are as close to the protected surface as possible.
2. Map how your traffic flow is across your DAAS:
To protect your assets, you must understand how traffic flows through the network and the
interconnectedness of your DAAS. You should know where the critical DAAS lives in the
3. network and who should be able to access it. Once you understand how your resources are
interconnected, you should ensure that the security controls are compatible between resources.
3. Build different prevention measures:
Employ various preventive measures to prevent hackers from breaking into the system. These
could be the following:
a) Identity Authentication:
The zero Trust security model is an identity-based access control method in which all users are
treated as untrusted entities. Data in a SaaS ecosystem is considered vulnerable unless its
access is limited, where it can be controlled. The first step to evaluate access to resources is to
centralize user management and initiate a robust authentication process. A centralized user
database that supports a single sign-on system is mandatory.
When the database is in place, you can initiate an authentication process like 2FA (two-factor
authentication) or MFA (multi-factor authentication) to secure your system. This ensures that
users accessing the applications are authorized personnel.
b) Device Authentication:
Device authentication deploys a centralized database for managing access privileges for
specific devices. Several users access their work applications through various devices. The
primary step is to secure these entry points and identify some risks associated with each
platform.
Using cross-functional input, choose security measures that are necessary for every platform.
This framework suggests which specific device qualifies as a managed device and how it can
be authenticated and monitored. To simplify device management, few organizations manage
“service access tiers” for establishing a standard level of security requirements for shared
devices.
c) Access Management:
After implementing identity and authentication mechanisms, the next step is to define and
enforce policies about who can access specific data and when they can access it. Zero Trust
supports the idea that employees should be given minimal permission to do their job; limiting
access minimizes risk. Access control is essential to any vendor risk assessment and
management and is integral to a long-term Zero Trust security implementation.
4) Keep Monitoring On A Regular Basis:
Continuously monitor network activity and inspect all traffic passing through the network.
Vulnerabilities change over time, and this process is critical to understanding key gaps in the
network and defending against them.
4. Conclusion:
With the increasing number of recent data breaches, it is essential to have a robust security
model in place to safeguard against cybercrime. However, traditional security models such as
the Security Rights and Access Management (DAC) model must be proven adequate against
sophisticated threats. Moving towards a Zero Trust model that treats all users as potential
threats and authenticates them only if they are known entities is a perfect way to protect
sensitive data and prevent significant attacks inside the network.
A Zero Trust security strategy is better at preventing cyber-attacks and has a higher resilience
against new vulnerabilities and exploits that might be uncovered during an attack. It provides a
solid defense system for your business to combat any eventuality that might put your brand
reputation at stake.
