Comprehensive and Detailed Explanation:

Understanding Residual Risk:

Residual riskis the amount of risk remainingafter controls and mitigations have been applied.

Risk appetitedefines the level of risk an organization iswilling to acceptbefore taking additional actions.

Why Option D is Correct:

TheCIO must clarify the organization’s "Risk Appetite"to determinehow much residual risk is acceptable.

If risk exceeds the appetite,additional security measuresneed to be implemented.

This aligns withISO 31000andNIST Risk Management Framework (RMF).

Why Other Options Are Incorrect:

A (Mitigation):Mitigationrefers toreducing risk, but it doesn’t define the acceptable level of residual risk.

B (Impact):Impact assessment measurespotential damage, but it does not determine what is acceptable.

C (Likelihood):Likelihood is theprobability of risk occurring, but not what level isacceptable.

Implementing the given commands in the Dockerfile ensures that the container runs with non-root user privileges. Running applications as a non-root user reduces the risk of privilege escalation attacks because even if anattacker compromises the application, they would have limited privileges and would not be able to perform actions that require root access.

A. Implementing the following commands in the Dockerfile: This directly addresses the privilege escalation attack surface by ensuring the application does not run with elevated privileges.

B. Installing an EDR on the container's host: While useful for detecting threats, this does not reduce the privilege escalation attack surface within the containerized application.

C.Designing a multi-container solution: While beneficial for modularity and remediation, it does not specifically address privilege escalation.

D. Running the container in an isolated network: This improves network security but does not directly reduce the privilege escalation attack surface.

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.

To protect company information on stolen mobile devices, implementingremote wipe proceduresensures data can be erased if a device is suspected lost or stolen.Biometric access controlwith enforced timeouts further secures the device, requiring biometric authentication periodically, thus limiting unauthorized access even if the device is stolen. Geofencing and certificates provide additional security layers but are less immediate protections against information exposure after theft. Application control and side-loading prevention are important for malware threats but less so for stolen device scenarios.

The table indicates varying load times for users accessing the website from different geographic locations. Customers from Australia and India are experiencingsignificantly higher load times compared to those from the United States. This suggests that latency and geographical distance are affecting the website's performance.

A. IDS (Intrusion Detection System): While an IDS is useful for detecting malicious activities, it does not address performance issues related to latency and geographical distribution of content.

B. CDN (Content Delivery Network): A CDN stores copies of the website's content in multiple geographic locations. By serving content from the nearest server to the user, a CDN can significantly reduce load times and improve user experience globally.

C. WAF (Web Application Firewall): A WAF protects web applications by filtering and monitoring HTTP traffic but does not improve performance related to geographical latency.

D. NAC (Network Access Control): NAC solutions control access to network resources but are not designed to address web performance issues.

Implementing a CDN is the best solution to resolve the performance issues observed in the log output.

The ATT&CK (Adversarial Tactics, Techniques, and Common Knowledge) framework is the best tool for a security analyst to use for threat modeling when looking for gaps in detection capabilities based on Advanced Persistent Threats (APTs) that may target the industry. Here’s why:

Comprehensive Framework: ATT&CK provides a detailed and structured repository of known adversary tactics and techniques based on real-world observations. It helps organizations understand how attackers operate and what techniques they might use.

Gap Analysis: By mapping existing security controls against the ATT&CK matrix, analysts can identify which tactics and techniques are not adequately covered by current detection and mitigation measures.

Industry Relevance: The ATT&CK framework is continuously updated with the latest threat intelligence, making it highly relevant for industries facing APT threats. It provides insights into specific APT groups and their preferred methods of attack.

The best location to test a newly released feature for an internal application, without affecting the production environment, is the staging environment. Here’s a detailed explanation:

Staging Environment: This environment closely mirrors the production environment in terms of hardware, software, configurations, and settings. It serves as a final testing ground before deploying changes to production. Testing in the staging environment ensures that the new feature will behave as expected in the actual production setup.

Isolation fromProduction: The staging environment is isolated from production, which means any issues arising from the new feature will not impact the live users or the integrity of the production data. This aligns with best practices in change management and risk mitigation.

Realistic Testing: Since the staging environment replicates the production environment, it provides realistic testing conditions. This helps in identifying potential issues that might not be apparent in a development or testing environment, which often have different configurations and workloads.

Unauthorized code changesand lack ofindependent verificationare directly mitigated bycode signing, which ensures that code is from a trusted source and has not been altered.

While digital signatures are part of code signing, the broader practice of code signing encompasses signature management, version integrity, and trusted sources.

Lightweight cryptography is irrelevant in this context; it's more about efficiency in constrained devices.

Non-repudiation is a benefit of digital signatures but doesn't directly solve the verification/integrity concerns alone.

FromCAS-005 Guide, Domain 4: Security Architecture, Tools, and Technologies:

“Code signing ensures that the code has not been tampered with and originates from a trusted developer.”
