Cloud Computing Models

Cloud computing can be categorized into several service models, each providing varying levels of control, flexibility, and management responsibilities:

  • Infrastructure as a Service (IaaS) provides virtualized computing resources over the Internet, allowing organizations to rent servers, storage, and networking infrastructure on a pay-as-you-go basis. This model offers the most control over IT resources but requires significant expertise in managing the infrastructure【Raza (Raza, M. 2024】.
  • Platform as a Service (PaaS) offers a platform allowing customers to develop, run, and manage applications without dealing with the underlying infrastructure. This model simplifies application deployment by providing a pre-configured environment【Akamai, n.d.】.
  • Software as a Service (SaaS) delivers software applications over the internet, eliminating organizations needing to install and run applications on their computers. This model is the easiest to use but offers the least control over the underlying infrastructure and applications【LinkedIn, 2023】.
  • Function as a Service (FaaS) is a serverless computing model that allows developers to execute code in response to events without the complexity of building and maintaining the infrastructure. This model provides scalability and cost-efficiency as users pay only for the execution time【DigitalOcean, n.d.】.
  • Desktop as a Service (DaaS) delivers virtual desktops to end users over the internet, providing a secure and manageable desktop environment. This model is beneficial for remote workforces and enhances security by centralizing data【Dgtl Infra, 2024】.
  • Backend as a Service (BaaS) offers backend cloud storage, database, and authentication services, allowing developers to focus on the front end and user experience. This model simplifies backend management and accelerates development cycles【Ekascloud, 2021】.
  • Database as a Service (DBaaS) provides managed database services, including setup, maintenance, and scaling, allowing organizations to focus on their applications without worrying about database administration【Microsoft Azure, n.d.】.

Comparison of Cloud Service Providers

The three leading cloud service providers—Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP)—offer a range of services, each with distinct advantages and disadvantages.


Cybersecurity in the Cloud

Migrating to the cloud brings numerous benefits, such as scalability, flexibility, and cost savings. However, it also introduces new cybersecurity challenges. Ensuring the security of cloud environments requires a multi-faceted approach:

  • Shared Responsibility Model: Cloud providers and customers share the responsibility for security. Providers are typically responsible for securing the infrastructure, while customers must secure their data and applications【IBM, 2024】.
  • Data Protection: Ensuring the confidentiality, integrity, and availability of data is paramount. This involves implementing strong encryption, access controls, and regular backups【Cloudflare, n.d.】.
  • Compliance and Governance: Adhering to regulatory requirements and establishing robust governance frameworks is critical for maintaining security and compliance in the cloud【IBM, 2024】.

The Cybersecurity Triad: CIA

The cybersecurity triad, also known as the CIA triad, is a fundamental concept in cybersecurity. It stands for Confidentiality, Integrity, and Availability:

  • Confidentiality: Ensuring that information is accessible only to those authorized to have access. This involves using encryption, access controls, and authentication mechanisms.
  • Integrity: Maintaining the accuracy and completeness of data over its lifecycle. Techniques include hashing, digital signatures, and checksums.
  • Availability: Ensuring that information and resources are available to authorized users when needed. This involves redundancy, failover mechanisms, and robust network architecture.

Intersectionality of the CIA Triad and Cloud Migration

Migrating to the cloud enhances an organization’s ability to respond to the cybersecurity triad:

  • Confidentiality: Cloud service providers offer advanced encryption technologies and stringent access controls to ensure data is accessible only to authorized users. This is crucial for maintaining the confidentiality of sensitive information, as cloud platforms typically implement robust security protocols and provide regular updates to counter emerging threats.
  • Integrity: Cloud platforms use checksums, hashing algorithms, and digital signatures to ensure data integrity. These mechanisms help detect and prevent data corruption or unauthorized modifications. Cloud providers also offer version control and auditing tools, allowing organizations to maintain accurate and complete data records over time.
  • Availability: Cloud services are designed to be highly available and resilient. They use redundant systems, distributed networks, and failover mechanisms to ensure that data and applications are accessible even during hardware failures or cyberattacks. This high level of availability is critical for maintaining business continuity and meeting service level agreements (SLAs).

NIST Cybersecurity Framework

The National Institute of Standards and Technology (NIST) provides a comprehensive framework for improving cybersecurity practices. The NIST Cybersecurity Framework consists of five core functions:

  1. Identify: Develop an understanding of the organizational context, resources, and cybersecurity risks.
  2. Protect: Implement safeguards to ensure the delivery of critical infrastructure services.
  3. Detect: Develop and implement appropriate activities to identify the occurrence of a cybersecurity event.
  4. Respond: Implement processes and procedures to respond to detected cybersecurity incidents.
  5. Recover: Implement plans for resilience and restoration of capabilities or services impaired due to a cybersecurity incident.

Intersectionality of the NIST Framework and Cloud Technology

Cloud technology aligns well with the NIST Cybersecurity Framework, offering tools and services that support each of the five core functions:

  • Identify: Cloud providers offer comprehensive tools for asset management, risk assessment, and governance. These tools help organizations identify and categorize their digital assets, assess vulnerabilities, and understand their risk posture.
  • Protect: Cloud platforms provide various security controls, including firewalls, encryption, and identity and access management (IAM) systems. These controls are essential for protecting data and systems from cyber threats.
  • Detect: Cloud services include monitoring and logging tools that enable continuous surveillance of systems and networks. These tools can detect suspicious activities and trigger alerts, allowing for timely responses to potential security incidents.
  • Respond: Cloud providers offer incident response capabilities, including automated workflows and playbooks for handling security breaches. These features enable organizations to respond swiftly and effectively to cyber incidents, minimizing damage and disruption.
  • Recover: Cloud platforms support disaster recovery and business continuity planning with features like data backups, replication, and automated failover. These capabilities ensure that organizations can quickly recover from disruptions and restore normal operations.

Conclusion

The intersectionality of cloud computing and cybersecurity presents both opportunities and challenges. Understanding the different cloud service models, evaluating the offerings of leading providers, and implementing robust cybersecurity measures are essential steps for organizations navigating this complex landscape. By leveraging frameworks such as the NIST Cybersecurity Framework and focusing on the CIA triad, organizations can enhance their security posture while taking full advantage of cloud computing capabilities.
