質問 # 113
A news organization wants to implement workflows that allow users to request that untruthful data be retraced and scrubbed from online publications to comply with the right to be forgotten. Which of the following regulations is the organization most likely trying to address?
正解：B
解説：
The General Data Protection Regulation (GDPR) is the regulation most likely being addressed by the news organization. GDPR includes provisions for the "right to be forgotten," which allows individuals to request the deletion of personal data that is no longer necessary for the purposes for which it was collected. This regulation aims to protect the privacy and personal data of individuals within the European Union.
質問 # 114
During a gap assessment, an organization notes that BYOD usage is a significant risk. The organization implemented administrative policies prohibiting BYOD usage. However, the organization has not implemented technical controls to prevent the unauthorized use of BYOD assets when accessing the organization's resources. Which of the following solutions should the organization implement to best reduce the risk of BYOD devices? (Choose two.)
正解：C、F
解説：
Conditional access allows the organization to restrict access based on device trust, enforcing user-to-device binding and blocking unauthorized BYOD devices.
Network Access Control (NAC) ensures only compliant and authorized devices can connect to the network, enforcing security configurations and reducing BYOD risks.
質問 # 115
A systems engineer is configuring a system baseline for servers that will provide email services. As part of the architecture design, the engineer needs to improve performance of the systems by using an access vector cache, facilitating mandatory access control and protecting against:
* Unauthorized reading and modification of data and programs
* Bypassing application security mechanisms
* Privilege escalation
* interference with other processes
Which of the following is the most appropriate for the engineer to deploy?
正解：B
解説：
The most appropriate solution for the systems engineer to deploy is SELinux (Security-Enhanced Linux).
Here's why:
Mandatory Access Control (MAC): SELinux enforces MAC policies, ensuring that only authorized users and processes can access specific resources. This helps in preventing unauthorized reading and modification of data and programs.
Access Vector Cache: SELinux utilizes an access vector cache (AVC) to improve performance. The AVC caches access decisions, reducing the need for repetitive policy lookups and thus improving system efficiency.
Security Mechanisms: SELinux provides a robust framework to enforce security policies and prevent bypassing of application security mechanisms. It controls access based on defined policies, ensuring that security measures are consistently applied.
Privilege Escalation and Process Interference: SELinux limits the ability of processes to escalate privileges and interfere with each other by enforcing strict access controls. This containment helps in isolating processes and minimizing the risk of privilege escalation attacks.
質問 # 116
A security engineer receives the following findings from a recent security audit:
* Data should be protected based on user permissions and roles.
* User action tracking should be implemented across the network.
* Digital identities should be validated across the data access workflow.
Which of the following is the first action the engineer should take to address the findings?
正解：C
解説：
The first action is to implement continuous and context-based authentication and authorization (A). Traditional authentication validates users only at login, which creates gaps during active sessions. Continuous authentication ensures validation throughout the data access workflow, incorporating contextual factors like device state, geolocation, and behavioral analysis. This directly aligns with audit findings requiring protection by role, identity validation, and action tracking.
Option B improves onboarding and monitoring but does not enforce continuous access control. Option C improves identity federation but does not provide session-by-session validation. Option D secures APIs but is too narrow for organization-wide identity workflows.
質問 # 117
An application security engineer is examining the IAM configuration for a workload. The following is a sample of the decoded payload and header:
" alg " : " None "
" typ " : " JWT "
" user " : " 98765 "
" iat " : 1680000000
" exp " : 1680003600
" sub " : " svc account "
" refresh " : true
" token_id " : " abc123 "
Which of the following is the most concerning risk?
正解：C
解説：
The best answer is B. Privilege escalation . The most critical issue is the JWT header value " alg " : " None " , which indicates an unsigned token. If a workload accepts such a token, an attacker may be able to alter claims such as subject, role, scope, or account identity and then present the modified token as valid. Because the sample already references a service account in the token claims, the most concerning IAM consequence is unauthorized elevation of access through token forgery or manipulation. CompTIA's SecurityX objectives include IAM and secure implementation of authentication and authorization controls; a broken token- validation scheme directly undermines authorization integrity.
Why the other options are not best:
A). Lateral movement could be a downstream result, but the immediate and primary risk in the token itself is unauthorized privilege gain. C. Credential stuffing involves reuse of stolen usernames and passwords, which is unrelated to this JWT issue. D. RCE from deserialization is a different application vulnerability class and is not the main concern shown by the JWT header and claims. The most direct risk here is privilege escalation via forged or altered tokens.
