Cloud-native services are becoming increasingly popular among organizations, with many developing new cloud applications or migrating existing ones to the cloud. However, organizations that fail to fully understand the need for robust cloud application security or selecting cloud service providers and their applications may face a range of commercial, financial, technical, legal, and compliance risks.
What is Cloud Application Security?
Cloud application security (Cloud AppSec) is the process of safeguarding applications across the entire cloud environment, data, and infrastructure within a cloud computing environment from potential vulnerabilities, threats, and attacks.
It involves a comprehensive approach that encompasses data security, identity and access management (IAM), application security, infrastructure security, and incident response and recovery.
By implementing robust security measures, organizations can ensure the confidentiality, integrity, and availability of their data and assets, while also maintaining compliance with regulatory requirements and industry standards like the Health Insurance Portability and Accountability Act (HIPPA) and General Data Protection Regulation (GDRP).
The Importance of Cloud Application Security
Cloud application security is essential for ensuring the confidentiality, integrity, and availability of data stored and processed in the cloud. By adopting strong security measures, organizations can:
Cloud Application Models: Automation and Shared Responsibilities
Cloud application security models help define the shared responsibilities between cloud service providers and customers in securing cloud environments. The following are the three primary models:
1. Infrastructure as a Service (IaaS)
In the IaaS model, the cloud service provider delivers virtualized computing resources over the internet. The provider is responsible for securing the underlying infrastructure, including the physical hardware, networking components, and cloud storage systems. Customers, on the other hand, are responsible for securing the operating systems, applications, and data hosted within the virtualized environment. Examples of IaaS providers include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP). This relationship is often referred to as the Shared Responsibility model.
2. Platform as a Service (PaaS)
The PaaS model provides customers with a development platform and tools to build, test, and deploy applications within a cloud environment. In this model, the cloud service provider is responsible for securing the underlying infrastructure and the platform itself, while customers are responsible for securing their applications and data. PaaS providers typically offer built-in security features and services that can be easily integrated into customer applications. Examples of PaaS providers include Heroku, Google App Engine, and Microsoft Azure App Service.
3. Software as a Service (SaaS)
In the SaaS model, the cloud service provider delivers fully managed applications that are accessible over the internet. The provider is responsible for securing the underlying infrastructure, the platform, and the applications themselves. Customers, however, still have a role to play in cloud security, as they are responsible for managing user access, configuring security settings, and ensuring compliance with regulatory requirements and industry standards. Examples of SaaS providers include Salesforce, Microsoft Office 365, and Google Workspace.
By working collaboratively with their cloud service providers and leveraging the security features and services available, organizations can ensure a robust cloud security posture within their cloud environments.
For example, F5's Distributed Cloud Services provide SaaS-based application management, networking, and security services such as adding a web application firewall, bot defense, and API security so organizations can deploy, operate, and secure their applications.
