Understanding Zero Trust Security

Questions and Answers

What is the principle of least privilege in the context of Zero Trust (ZT)?

Users and programs should have only the minimal privileges necessary to perform their tasks. (correct)

Users should be able to access resources at any time without restrictions.

Users should have unrestricted access to all applications.

All users must be identified before gaining access to any system.

How does Zero Trust (ZT) reduce security architecture complexity?

By eliminating all security barriers within the network.

By consolidating all resources into a single access point.

By creating focused perimeters around applications and identity. (correct)

By allowing all users to access all applications under supervision.

What role does micro-segmentation play in Zero Trust (ZT)?

It allows users to share access with others in the network.

It facilitates the merging of all security protocols into one framework.

It isolates workloads by creating zones in the IT environment for enhanced security. (correct)

It enables unlimited access to cloud services for all users.

Study Notes

Security Challenges

Complexity in IT environments reduces visibility and complicates configurations, making organizations more vulnerable to attacks.
Emerging IT paradigms like hybrid cloud, multi-cloud, and edge computing exacerbate access control management challenges.

Zero Trust (ZT) Framework

ZT treats all entities seeking application access as malicious, thereby eliminating the assumption of trust.
Instead of policing network borders, ZT creates focused security "islands" around applications and data.
ZT strategies require multiple attributes for access management compared to traditional security mechanisms.

Principle of Least Privilege

ZT enforces the principle by granting users the minimum access necessary to perform their tasks.
Access is strictly controlled, ensuring users connect to only the required applications and services through micro-segmentation.

Reduced Risk of Compromise

ZT reduces compromise risks by limiting the attack surface and lateral movement of attackers.
It accelerates breach detection and containment efforts.

Attack Surface and Impact Radius

Access is determined based on user attributes, device security hygiene, request context, and environmental risk.
Resource hiding limits visibility to only authenticated users, minimizing unauthorized access and privilege escalation.

Access Management Model

Utilizes a Policy Enforcement Point (PEP) and Policy Decision Point (PDP) for authorization processes.
Ensures only vetted applications can interact with the server's resources, isolating applications to protect sensitive data.

Eliminating Complexity in Access Control

ZT models avoid outdated access control mechanisms such as nested groups and antiquated authorization models.
Removes issues with orphaned groups and inconsistent access decisions that complicate management and create security gaps.

Traditional vs. Zero Trust Security

Traditional models grant access based solely on network perimeter defenses, leading to potential vulnerabilities once inside.
ZT ensures that every internal resource independently assesses access, thus tightening security and minimizing exposure to threats.
