An engineering team determines the cost to mitigate certain risks is higher than the asset values The team must ensure the risks are prioritized appropriately. Which of the following is the best way to address the issue?
Correct Answer:
D
When the cost to mitigate certain risks is higher than the asset values, the best approach is to purchase insurance. This method allows the company to transfer the risk to an insurance provider, ensuring that financial losses are covered in the event of an incident. This approach is cost-effective and ensures that risks are prioritized appropriately without overspending on mitigation efforts.

An organization wants to implement a platform to better identify which specific assets are affected by a given vulnerability. Which of the following components provides the best foundation to achieve this goal?
Correct Answer:
B
A Configuration Management Database (CMDB) provides the best foundation for identifying which specific assets are affected by a given vulnerability. A CMDB maintains detailed information about the IT environment, including hardware, software, configurations, and relationships between assets. This comprehensive view allows organizations to quickly identify and address vulnerabilities affecting specific assets. References:

use of CMDBs for effective configuration and asset management.

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?
Correct Answer:
A
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.

Correct Answer:
C
cons
Dynamic Application Security Testing (DAST) is crucial for identifying and addressing security vulnerabilities during the software development life cycle (SDLC). Ensuring that DAST scans are routinely scheduled helps in maintaining a secure development process. Why Routine DAST Scans?
✑ Continuous Security Assessment: Regular DAST scans help in identifying
vulnerabilities in real-time, ensuring they are addressed promptly.
✑ Compliance: Routine scans ensure that the development process complies with security standards and regulations.
✑ Proactive Threat Mitigation: Regular scans help in early detection and mitigation of potential security threats, reducing the risk of breaches.
✑ Integration into SDLC: Ensures security is embedded within the development process, promoting a security-first approach.
Other options, while relevant, do not directly address the continuous assessment and proactive identification of threats:
✑ A. If developers are unable to promote to production: This is more of an
operational issue than a security assessment.
✑ B. If DAST code is being stored to a single code repository: This concerns code management rather than security testing frequency.
✑ D. If role-based training is deployed: While important, training alone does not ensure continuous security assessment.

A security engineer is developing a solution to meet the following requirements?
• All endpoints should be able to establish telemetry with a SIEM.
• All endpoints should be able to be integrated into the XDR platform.
• SOC services should be able to monitor the XDR platform
Which of the following should the security engineer implement to meet the requirements?
Correct Answer:
D
To meet the requirements of having all endpoints establish telemetry with a SIEM, integrate into an XDR platform, and allow SOC services to monitor the XDR platform, the best approach is to implement Host Intrusion Prevention Systems (HIPS) and a host-based firewall. HIPS can provide detailed telemetry data to the SIEM and can be integrated into the XDR platform for comprehensive monitoring and response. The host- based firewall ensures that only authorized traffic is allowed, providing an additional layer of security.
