Zero Trust Architecture
(ZTA)
ENHANCING CYBERSECURITY WITH A “NEVER TRUST,
ALWAYS VERIFY” APPROACH
Introduction to Zero Trust
Architecture
What is Zero Trust?
• A security model where no one is trusted by default.
• Every action is authenticated and authorized.
Why is it important?
• Modern threats, like insider breaches and hackers, make
traditional “trusted” systems vulnerable.
• It’s especially critical today with remote work and cloud systems.
Traditional Security vs. Zero Trust
Traditional Perimeter-Based Security:
• Assumes that everything inside the network is trusted.
• Relies heavily on firewalls, VPNs, and perimeter defenses.
Zero Trust Approach:
• No implicit trust; verifies every request from every user, device, and
network.
• Verifies every person or device, no matter if they’re inside or
outside the network.
Core Principles of Zero Trust
Architecture
1. Verify Explicitly
• Continuous Authentication & Authorization: Each user and device must be authenticated and authorized every
time they attempt to access a resource. This includes multi-factor authentication (MFA), device verification, and
other checks.
3. Assume Breach
• Micro-Segmentation: The network is divided into smaller zones, each with its own security policies, to limit the
damage of a breach. This limits lateral movement within the network.
• Monitoring & Logging: Continuous monitoring of all traffic, behaviors, and access patterns is essential. This
helps detect anomalies that may indicate a breach or malicious behavior.
• Containment and Response: Quickly containing any breaches and responding to incidents reduces their
potential impact.
2. Least Privilege Access
• Role-Based Access Control (RBAC) and Attribute-Based Access Control (ABAC): Access should be restricted based
on the role, context, or attributes of the user or device. This prevents over-privileged access to sensitive resources.
• Dynamic Policy Enforcement: Policies should adapt to changing risk levels, such as user location, device health, and
real-time threat intelligence.
Components of Zero Trust
Architecture
1.Identity and Access Management (IAM):
Strictly verifies the identity of all users, devices, and applications accessing the network.
IAM controls who can access specific resources, ensuring that each user has the correct
permissions based on their role
2.Multi-Factor Authentication (MFA):
MFA adds an extra layer of security by requiring multiple forms of verification, making it
harder for unauthorized users to gain access.
3.Microsegmentation:
Microsegmentation breaks down a network into smaller zones, limiting access to
sensitive data and containing potential threats.
4.Continuous Monitoring:
Continuously monitors network activity and user behavior to detect anomalies in real-
time.
