Study Notes

PDP and PIP

Malicious actors may attempt to spoof administrators to gain unauthorized access to administrative consoles.
Multi-Factor Authentication (MFA) can mitigate spoofing threats through enhanced credential protection.
Assurance checks should be performed to confirm that an administrator cannot access data from a different organization.
Logging of all administrative actions should be implemented, with the option for customer log sharing for transparency.

IAM for ZT Users

Identity providers may face compromises, leading to credential harvesting by malicious actors.
Security assessments of identity providers ensure they are suitable for protecting user identities.

Remote Access and Third-Party Service Providers

Zero Trust (ZT) policies can authenticate third-party users and determine necessary access privileges.
Hiding unused assets prevents lateral movement, thereby reducing potential attack surfaces in supply chain risks.

Staff Access to Hybrid Environments

Access to cloud service root accounts (AWS, Azure) must be strictly controlled to prevent misuse.
The use of ZT policies ensures consistent security measures across all accounts and subscriptions.
Transparency over cloud assets is reduced, thus minimizing the attack surface in public domains.

SaaS & PaaS

Access to SaaS and PaaS is categorized into service-level access and feature-level access.
Implementing Zero Trust facilitates Attribute-Based Access Control (ABAC) for defining access features within services.

Role-Based Access Control

Organizations with network segments for different security needs can create role-based policies effectively.
Example scenario: A soap manufacturing company restricts access to trade secrets exclusively for server administrators and ingredient engineers.
Zero Trust helps prevent unauthorized movements using compromised credentials through device verification.

Remote Access Considerations

Remote access is now common and includes employees, contractors, and suppliers, posing risks for lateral movement.
Security can be bolstered using Virtual Desktop Infrastructure (VDI) and corporate cloud workstations.
ZT enables administrators to limit remote access to only authorized applications and resources, reducing exposure.
Device authentication is critical to validate user requests before granting access.

Access via Mobile Devices

Organizations often provide services accessible from mobile devices like smartphones and tablets, emphasizing the need for robust security measures in mobile access management.
