Exam CAS-004 topic 1 question 269 discussion

The designs that must be considered to ensure the architect meets these requirements are: Network services must be designed to ensure multiple diverse layers of redundancy. Establishment of warm and hot sites for continuity of operations. Implementation and configuration of a SOAR (Security Orchestration, Automation and Response) system to automate defensive and responsive actions to reduce human operator demands. Heterogeneous architecture refers to the use of different types of hardware and software in a system. It is not related to the design of network services to ensure multiple diverse layers of redundancy.

Source: Verifying each answer against Chat GPT, my experience, other test banks, a written book, and weighing in the discussion from all users to create a 100% accurate guide for myself before I take the exam. (It isn't easy because of the time needed, but it is doing my diligence)

Going with BCH: Reconstitution -> C (Containers) provides rapid service restoration from a verified state. Redundancy -> B (Geographic Distribution) provides a crucial layer of diverse redundancy. Automation -> H (SOAR) directly provides the necessary automation for defense/response.

Geographic distribution of critical data and services: This ensures redundancy by spreading data across different physical locations, so if one area is compromised, other copies remain accessible. This also supports quick reconstitution from a known-good state by allowing access to unaffected data copies. Hardened and verified container usage: Hardened containers provide increased security by minimizing the attack surface within them. Verification processes ensure the containers are trustworthy and haven't been tampered with, further enhancing security and facilitating rapid reconstitution. Establishment of warm and hot sites for continuity of operations: Warm and hot sites allow for rapid switchover to operational systems in the event of a disaster or major outage, minimizing downtime and enabling business continuity. This aligns with the requirement for quick reconstitution and redundancy.

I think CFH makes more sense to me. Geography doesn't help with supply-chain attacks, or at least not for Solarwinds and Cisco. Containers can be self-healing, and SOAR helps with security automation and response.

B. Geographic distribution of critical data and services: Geographic distribution helps ensure that services and data are available from multiple locations, providing redundancy in case of regional disruptions. It also enhances the organization's ability to quickly recover from any attacks or disasters, as the services can be restored or accessed from a different region. E. Establishment of warm and hot sites for continuity of operations: A hot site allows services and data to be quickly restored from a fully operational backup location, while a warm site has some infrastructure ready to be scaled up in case of failure. Both are crucial for business continuity and meet the requirement of quickly reconstituting services from a known-good state. H. Implementation and configuration of a SOAR (Security Orchestration, Automation, and Response): SOAR platforms automate defensive and responsive actions. They can detect, analyze, and respond to threats without requiring manual intervention, which reduces human operator demands.

Company is concerned about APTs, so BCH wouldaddress all oftheir requirements. A Warm/cold site doesn't solve APT issue, which is what the organization is concerned about and the reason why they are building this design.

B. Geographic distribution of critical data and services Ensures redundancy and resilience by distributing data and services across multiple locations, reducing the impact of localized failures or attacks. C. Hardened and verified container usage Facilitates quick reconstitution of services from known-good states using secure, consistent container images. H. Implementation and configuration of a SOAR (Security Orchestration, Automation, and Response) Automates defensive and responsive actions, reducing human operator demands and ensuring rapid, consistent responses to security incidents.

Unless that ATP is planning to magically summon a tornado to destroy your office, I don't see how establishing a Hot/Warm Site is going to do anything to help you. For that reason, my answer is B, C, H.

Geographic distribution of critical data and services - This ensures redundancy and helps in quickly recovering from a known good state if one location gets compromised; Hardened and verified container usage - Containers can be reconstituted quickly, and if they are hardened and verified, they are resistant to compromise; Implementation and configuration of a SOAR (Security Orchestration, Automation, and Response) - This primarily deals with the automation of defensive and responsive actions, making it relevant to the third requirement.

A. Increased efficiency by embracing advanced caching capabilities B. Geographic distribution of critical data and services H. Implementation and configuration of a SOAR Explanation: A: Advanced caching can be used to improve the speed of reconstitution from a known-good state, which is one of the requirements. B: Geographic distribution of critical data and services can be used to ensure multiple diverse layers of redundancy. H: The implementation and configuration of a SOAR (Security Orchestration, Automation and Response) can help automate defensive and responsive actions, thereby reducing the demands on human operators.

Based on the provided requirements, the following designs should be considered to ensure the architect meets the organization's needs:

B, C, and H are the most appropriate designs to ensure that the architect meets the requirements. B. Geographic distribution of critical data and services will ensure that multiple sites are available to restore data and services in the event of an APT attack. This will also reduce the impact of DDoS attacks by ensuring that traffic is spread across multiple sites. C. Hardened and verified container usage can help to isolate services from one another and protect them from APT attacks. Containerization can provide a secure and scalable platform for deploying services, which can be reconstituted quickly from a known-good state. H. Implementation and configuration of a SOAR platform will automate the process of responding to and mitigating APT attacks. The SOAR platform will allow the organization to create a set of automated actions that can be executed in response to security events, reducing the human operator demands.

F. Heterogeneous architecture - vendor diversity for redundancy G. Deployment of IPS services that can identify and block malicious traffic- to defend H. Implementation and configuration of a SOAR- for automation of recover
