Question 1
Of the following options, which risk/threat does SDP mitigate by mandating micro-segmentation and implementing least privilege?
  1. Identification and authentication failures
  2. Injection
  3. Security logging and monitoring failures
  4. Broken access control
Correct answer: D
Explanation:
SDP mitigates the risk of broken access control by mandating micro-segmentation and implementing least privilege. Micro-segmentation divides the network into smaller, isolated segments that can prevent unauthorized access and contain lateral movement. Least privilege grants the minimum necessary access to users and devices for specific resources, while hiding all other assets from their view. This reduces the attack surface and prevents attackers from exploiting weak or misconfigured access controls

Question 2
What should an organization's data and asset classification be based on?
  1. Location of data
  2. History of data
  3. Sensitivity of data
  4. Recovery of data
Correct answer: C
Explanation:
Data and asset classification should be based on the sensitivity of data, which is the degree to which the data requires protection from unauthorized access, modification, or disclosure. Data sensitivity is determined by the potential impact of data loss, theft, or corruption on the organization, its customers, and its partners. Data sensitivity can also be influenced by legal, regulatory, and contractual obligations.Reference:Certificate of Competence in Zero Trust (CCZT) prepkit, page 10, section 2.1.1Identify and protect sensitive business data with Zero Trust, section 1Secure data with Zero Trust, section 1SP 800-207, Zero Trust Architecture, page 9, section 3.2.1

Question 3
Which security tools or capabilities can be utilized to automate the response to security events and incidents?
  1. Single packet authorization (SPA)
  2. Security orchestration, automation, and response (SOAR)
  3. Multi-factor authentication (MFA)
  4. Security information and event management (SIEM)
Correct answer: B
Explanation:
SOAR is a collection of software programs developed to bolster an organization's cybersecurity posture. SOAR tools can automate the response to security events and incidents by executing predefined workflows or playbooks, which can include tasks such as alert triage, threat detection, containment, mitigation, and remediation. SOAR tools can also orchestrate the integration of various security tools and data sources, and provide centralized dashboards and reporting for security operations.Reference:Certificate of Competence in Zero Trust (CCZT) prepkit, page 23, section 3.2.2Security Orchestration, Automation and Response (SOAR) - GartnerSecurity Automation: Tools, Process and Best Practices - Cynet, section ''What are the different types of security automation tools?''Introduction to automation in Microsoft Sentinel

Question 5
Which component in a ZTA is responsible for deciding whether to grant access to a resource?
  1. The policy enforcement point (PEP)
  2. The policy administrator (PA)
  3. The policy engine (PE)
  4. The policy component
Correct answer: C
Explanation:
The policy engine (PE) is the component in a ZTA that is responsible for deciding whether to grant access to a resource. The PE evaluates the policies and the contextual data collected from various sources, such as the user identity, the device posture, the network location, the resource attributes, and the environmental factors, and then generates an access decision. The PE communicates the access decision to the policy enforcement point (PEP), which enforces the decision on the resource.Reference:Certificate of Competence in Zero Trust (CCZT) prepkit, page 14, section 2.2.2What Is Zero Trust Architecture (ZTA)? - F5, section ''Policy Engine''What is Zero Trust Architecture (ZTA)? | NextLabs, section ''Core Components''[SP 800-207, Zero Trust Architecture], page 11, section 3.3.1

Question 6
What is the function of the rule-based security policies configured on the policy decision point (PDP)?
  1. Define rules that specify how information can flow
  2. Define rules that specify multi-factor authentication (MFA) requirements
  3. Define rules that map roles to users
  4. Define rules that control the entitlements to assets
Correct answer: D
Explanation:
Rule-based security policies are a type of attribute-based access control (ABAC) policies that define rules that control the entitlements to assets, such as data, applications, or devices, based on the attributes of the subjects, objects, and environment. The policy decision point (PDP) is the component in a zero trust architecture (ZTA) that evaluates the rule-based security policies and generates an access decision for each request.Reference:Certificate of Competence in Zero Trust (CCZT) prepkit, page 14, section 2.2.2A Zero Trust Policy Model | SpringerLink, section ''Rule-Based Policies''Zero Trust architecture: a paradigm shift in cybersecurity - PwC, section ''Security policy and control framework''

Question 9
The following list describes the SDP onboarding process/procedure.
What is the third step? 1. SDP controllers are brought online first. 2.
Accepting hosts are enlisted as SDP gateways that connect to and authenticate with the SDP controller. 3.
  1. Initiating hosts are then onboarded and authenticated by the SDP gateway
  2. Clients on the initiating hosts are then onboarded and authenticated by the SDP controller
  3. SDP gateway is brought online
  4. Finally, SDP controllers are then brought online
Correct answer: A
Explanation:
The third step in the SDP onboarding process is to onboard and authenticate the initiating hosts, which are the clients that request access to the protected resources. The initiating hosts connect to and authenticate with the SDP gateway, which acts as an accepting host and a proxy for the protected resources. The SDP gateway verifies the identity and posture of the initiating hosts and grants them access to the resources based on the policies defined by the SDP controller.Reference:Certificate of Competence in Zero Trust (CCZT) prepkit, page 21, section 3.1.26 SDP Deployment Models to Achieve Zero Trust | CSA, section ''Deployment Models Explained''Software-Defined Perimeter (SDP) and Zero Trust | CSA, page 7, section 3.1
