Ace Your CAS-005 SecurityX Exam

The security diagram proposed by the security architect depicts a Zero Trust security model. Zero Trust is asecurity framework that assumes all entities, both inside and outside the network, cannot be trusted and must be verified before gaining access to resources.

Key Characteristics of Zero Trust in the Diagram:

Role-based Access Control: Ensures that users have access only to the resources necessary for their role.

Mandatory Access Control: Additional layer of security requiring authentication for access to sensitive areas.

Network Access Control: Ensures that devices meet security standards before accessing the network.

Multi-factor Authentication (MFA): Enhances security by requiring multiple forms of verification.

This model aligns with the Zero Trust principles of never trusting and always verifying access requests, regardless of their origin.

In a federated environment divided by region, if user identities are not synchronized across regions, authentication may be slow or fail when employees travel. CAS-005 IAM guidance states that identity synchronization ensures user attributes and credentials are consistently available in all regions, reducing latency and login issues.

Option A creates separate identities, which breaks single identity management.

Option C is unrelated to the login performance issue.

Option D may resolve SSO appliance sync but not cross-region identity data availability.

Software Composition Analysis (SCA) is the best method for identifying all components, dependencies, and open-source libraries used inan application. It ensures that organizations track and manage vulnerabilities in third-party code before deployment.

SCA tools generate a Software Bill of Materials (SBOM), which provides a full representation of the code and modules used in the application.

Other options:

Static Application Security Testing (SAST) (C) checks for vulnerabilities but does not map dependencies.

Interactive Application Security Testing (IAST) (D) works at runtime, not before deployment.

Runtime Application Self-Protection (RASP) (B) works while the application is running.

Privileged Access Management (PAM)restricts elevated permissions, reducing the risk of widespread ransomware attacks.Multi-Factor Authentication (MFA)protects against credential theft and ensures that even if passwords are compromised, accounts are not easily accessible.Network segmentationbreaks the flat network into secure zones, limiting lateral movement by attackers. SD-WAN and BGP relate to network routing and efficiency, not security architecture specifically. Remote access VPN secures external access but does not solve internal flat network issues. Network Access Control (NAC) is helpful but secondary compared to PAM, MFA, and segmentation in this context.
