Demystifying NIST 800-145 Cloud Computing Definition: A Comprehensive Guide
Cloud computing is a technology that has taken the business world by storm. It allows businesses to access computing resources over the internet, reducing the need for on-premise hardware and software. However, with this innovation comes the need to understand the security concerns associated with cloud computing.
The National Institute of Standards and Technology (NIST) is a government agency that provides cybersecurity guidelines for businesses. The NIST 800-145 publication specifically addresses cloud computing security and provides a comprehensive definition of cloud computing. In this article, we will demystify the NIST 800-145 cloud computing definition.
Understanding NIST 800-145 Cloud Computing Definition
The NIST 800-145 cloud computing definition defines cloud computing as a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.
The NIST definition is broken down into three service models: Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). Understanding these service models is essential to understanding the NIST cloud computing definition.
SaaS refers to cloud software applications that a third-party provider hosts and makes available to customers over the internet. Examples of SaaS include email, customer relationship management (CRM), and payroll software.
PaaS refers to cloud computing platforms that a third-party provider hosts and makes available to customers over the internet. Customers can develop custom applications using the platform without having to worry about underlying infrastructure. Examples of PaaS include Microsoft Azure and Google App Engine.
IaaS refers to cloud computing infrastructure that a third-party provider hosts and makes available to customers over the internet. Customers can use this infrastructure to run their own software or applications. Examples of IaaS include Amazon Web Services (AWS) and Microsoft Azure.
Benefits of NIST 800-145 Cloud Computing Definition
The NIST 800-145 cloud computing definition provides several benefits to businesses. First, it offers a standardized definition for cloud computing, which helps businesses understand the technology and its associated security concerns. The definition also provides a framework for evaluating cloud service providers and their offerings, allowing businesses to make informed decisions about which provider to use.
Additionally, the definition provides guidelines for implementing cloud computing securely. By following the NIST guidelines, businesses can reduce the risk of data breaches and other security incidents in the cloud.
Conclusion
In conclusion, cloud computing is a critical technology for modern businesses. However, it comes with security concerns that must be addressed. The NIST 800-145 cloud computing definition provides a comprehensive understanding of cloud computing and its associated security concerns. By following the guidelines set forth in the definition, businesses can take advantage of the benefits of cloud computing while ensuring the security of their data.
