Audit findings indicate several user endpoints are not utilizing full disk encryption During me remediation process, a compliance analyst reviews the testing details for the endpoints and notes the endpoint device configuration does not support full disk encryption Which of the following is the most likely reason me device must be replaced'
Correct Answer:
D
The most likely reason the device must be replaced is that the motherboard was not configured with a TPM (Trusted Platform Module) from the OEM (Original Equipment Manufacturer) supplier.
Why TPM is Necessary for Full Disk Encryption:
✑ Hardware-Based Security: TPM provides a hardware-based mechanism to store encryption keys securely, which is essential for full disk encryption.
✑ Compatibility: Full disk encryption solutions, such as BitLocker, require TPM to ensure that the encryption keys are securely stored and managed.
✑ Integrity Checks: TPM enables system integrity checks during boot, ensuring that the device has not been tampered with.
Other options do not directly address the requirement for TPM in supporting full disk encryption:
✑ A. The HSM is outdated: While HSM (Hardware Security Module) is important for
security, it is not typically used for full disk encryption.
✑ B. The vTPM was not properly initialized: vTPM (virtual TPM) is less common and not typically a reason for requiring hardware replacement.
✑ C. The HSM is vulnerable to common exploits: This would require a firmware upgrade, not replacement of the device.
✑ E. The HSM does not support sealing storage: Sealing storage is relevant but not the primary reason for requiring TPM for full disk encryption.

A financial technology firm works collaboratively with business partners in the industry to share threat intelligence within a central platform This collaboration gives partner organizations the ability to obtain and share data associated with emerging threats from a variety of adversaries Which of the following should the organization most likely leverage to facilitate this activity? (Select two).
Correct Answer:
DE
✑ D. STIX (Structured Threat Information eXpression): STIX is a standardized language for representing threat information in a structured and machine-readable format. It facilitates the sharing of threat intelligence by ensuring that data is consistent and can be easily understood by all parties involved.
✑ E. TAXII (Trusted Automated eXchange of Indicator Information): TAXII is a transport mechanism that enables the sharing of cyber threat information over a secure and trusted network. It works in conjunction with STIX to automate the exchange of threat intelligence among organizations.
Other options:
✑ A. CWPP (Cloud Workload Protection Platform): This focuses on securing cloud workloads and is not directly related to threat intelligence sharing.
✑ B. YARA: YARA is used for malware research and identifying patterns in files, but it is not a platform for sharing threat intelligence.
✑ C. ATT&CK: This is a knowledge base of adversary tactics and techniques but does not facilitate the sharing of threat intelligence data.
✑ F. JTAG: JTAG is a standard for testing and debugging integrated circuits, not related to threat intelligence.

Asecuntv administrator is performing a gap assessment against a specific OS benchmark The benchmark requires the following configurations be applied to endpomts:
• Full disk encryption
* Host-based firewall
• Time synchronization
* Password policies
• Application allow listing
* Zero Trust application access
Which of the following solutions best addresses the requirements? (Select two).
Correct Answer:
CD
To address the specific OS benchmark configurations, the following solutions are most appropriate:
* C. SCAP (Security Content Automation Protocol): SCAP helps in automating vulnerability management and policy compliance, including configurations like full disk encryption, host-based firewalls, and password policies.
* D. SASE (Secure Access Service Edge): SASE provides a framework for Zero Trust network access and application allow listing, ensuring secure and compliant access to applications and data.
These solutions together cover the comprehensive security requirements specified in the OS benchmark, ensuring a robust security posture for endpoints.

✑ "Zero Trust Networks: Building Secure Systems in Untrusted Networks" by Evan Gilman and Doug Barth: Covers the principles of Zero Trust and how SASE can implement them.
By implementing SCAP and SASE, the organization ensures that all the specified security configurations are applied and maintained effectively.
Which of the following best describes the challenges associated with widespread adoption of homomorphic encryption techniques?
Correct Answer:
D
Homomorphic encryption allows computations to be performed on encrypted data without decrypting it, providing strong privacy guarantees. However, the adoption of homomorphic encryption is challenging due to several factors:
✑ A. Incomplete mathematical primitives: This is not the primary barrier as the
theoretical foundations of homomorphic encryption are well-developed.
✑ B. No use cases to drive adoption: There are several compelling use cases for
homomorphic encryption, especially in privacy-sensitive fields like healthcare and finance.
✑ C. Quantum computers not yet capable: Quantum computing is not directly related
to the challenges of adopting homomorphic encryption.
✑ D. Insufficient coprocessor support: The computational overhead of homomorphic encryption is significant, requiring substantial processing power. Current general- purpose processors are not optimized for the intensive computations required by homomorphic encryption, limiting its practical deployment. Specialized hardware or coprocessors designed to handle these computations more efficiently are not yet widely available.

A company that uses containers to run its applications is required to identify vulnerabilities on every container image in a private repository The security team needs to be able to quickly evaluate whether to respond to a given vulnerability Which of the following, will allow the security team to achieve the objective with the last effort?
Correct Answer:
B
A centralized Software Bill of Materials (SBoM) is the best solution for identifying vulnerabilities in container images in a private repository. An SBoM provides a comprehensive inventory of all components, dependencies, and their versions within a container image, facilitating quick evaluation and response to vulnerabilities.
Why Centralized SBoM?
✑ Comprehensive Inventory: An SBoM lists all software components, including their versions and dependencies, allowing for thorough vulnerability assessments.
✑ Quick Identification: Centralizing SBoM data enables rapid identification of affected containers when a vulnerability is disclosed.
✑ Automation: SBoMs can be integrated into automated tools for continuous monitoring and alerting of vulnerabilities.
✑ Regulatory Compliance: Helps in meeting compliance requirements by providing a clear and auditable record of all software components used.
Other options, while useful, do not provide the same level of comprehensive and efficient vulnerability management:
✑ A. SAST scan reports: Focuses on static analysis of code but may not cover all components in container images.
✑ C. CIS benchmark compliance reports: Ensures compliance with security benchmarks but does not provide detailed component inventory.
✑ D. Credentialed vulnerability scan: Useful for in-depth scans but may not be as efficient for quick vulnerability evaluation.
