The differences between working for a community agency or residential treatment setting Versus a private practice

Full Answer Section

• SaaS (Software as a Service): In SaaS, the CSP provides a complete software application accessible over the internet. The enterprise has the least control over the underlying infrastructure and software. The CSP assumes the primary responsibility for security, including data protection, application security, and infrastructure security. However, the enterprise is still responsible for securing its own data within the SaaS environment and ensuring compliance with relevant regulations.

Question 2:

• Data at rest and data in motion

Question 3:

• Cloud Lock-in: Cloud lock-in refers to the situation where an organization becomes overly dependent on a specific cloud provider, making it difficult or costly to migrate to another provider.
  • Impacts:
    • Reduced Flexibility: Limits the ability to leverage competitive pricing or explore alternative solutions.
    • Vendor Lock-in: Can increase reliance on a single vendor, potentially reducing bargaining power and increasing costs.
    • Security Risks: Vendor lock-in can increase security risks if the chosen provider experiences security breaches or service disruptions.
  • Trends Addressing Cloud Lock-in:
    • Open Source Technologies: Utilizing open source technologies and open standards can reduce vendor lock-in by increasing portability and interoperability.
    • Multi-cloud and Hybrid Cloud Strategies: Adopting a multi-cloud or hybrid cloud approach can mitigate vendor lock-in by diversifying across multiple providers.
    • Cloud-Agnostic Architectures: Designing and implementing cloud-agnostic architectures can make it easier to migrate applications and data between different cloud providers.

Question 4:

• NIST Security Controls: NIST (National Institute of Standards and Technology) provides a comprehensive framework for cybersecurity. NIST security controls are a set of safeguards designed to protect information systems and organizations from various cyber threats.
• NIST Security Control Structure: NIST organizes security controls into families and classes.
  • Families: Group related controls together (e.g., Access Control, Identification and Authentication, System and Information Integrity).
  • Classes: Further categorize controls within each family (e.g., Access Control: Identification and Authentication, Access Control: Authorization).
• Use in Risk Management: NIST security controls provide a standardized framework for organizations to assess their security posture, identify and prioritize risks, and implement appropriate security measures. They can be used to guide the selection, implementation, and evaluation of security controls throughout the organization.

Question 5:

• Policy:
  • Least Privilege: The principle of least privilege dictates that users should only be granted the minimum level of access necessary to perform their job duties. This helps to minimize the impact of potential security breaches.  
• Risk Management:
  • Threat Modeling: Conducting regular threat modeling exercises to identify and assess potential threats to cloud environments. This helps organizations prioritize security controls and allocate resources effectively.

Question 6:

True

Question 7:

• Acts of Nature: Data centers must be designed to withstand natural disasters such as earthquakes, floods, and hurricanes. This includes measures such as raised floors, backup power generators, and robust cooling systems.
• Business Continuity and Disaster Recovery: Data centers must have robust business continuity and disaster recovery plans in place to ensure that critical operations can continue in the event of a disruption. This may include redundant systems, off-site backups, and disaster recovery sites.

Question 8:

False

When private cloud Internet and enterprise users are segregated in a defense-in-depth manner, user data should be encrypted both at rest and in transit to enhance security and protect sensitive information.

Sample Answer

Question 1:

• IaaS (Infrastructure as a Service): In IaaS, the CSP provides the fundamental building blocks for cloud IT: compute, storage, and networking. The enterprise retains the highest degree of control over the operating systems, applications, and data. However, the CSP is responsible for the security of the underlying infrastructure, including physical security, network security, and virtualization.
• PaaS (Platform as a Service): In PaaS, the CSP provides a platform for developers to build, run, and manage applications. The CSP manages the underlying infrastructure, operating systems, and runtime environments. The enterprise has more control over the applications and data, but the responsibility for security is shared between the enterprise and the CSP. The enterprise is responsible for application security, data security within the application, and user access controls. The CSP is responsible for the security of the underlying platform, including infrastructure security, operating system security, and platform-level security controls.
