There are database-specific PaaS providers, for instance, as well as an emerging type called high productivity application PaaS (hpaPaaS), which features a graphical, low-code approach to development. See Azure security best practices and patterns for more security best practices to use when you’re designing, deploying, and managing your cloud solutions by using Azure. As highlighted Examples of platform-as-a-service are AWS Lambda, Microsoft Azure PaaS, Google App Engine, Apache Stratos, and Force.com, which is a development platform for Salesforce customers. Validating security defenses is as important as testing any other functionality. Initially, Azure PaaS services (for example, web roles and Azure SQL) provided little or no traditional network perimeter defenses. While key management is an additional responsibility, you have areas in a PaaS deployment that you no longer have to manage so you can shift resources to key management. Azure App Service is a PaaS offering that lets you create web and mobile apps for any platform or device and connect to data anywhere, in the cloud or on-premises. To help facilitate this process, Microsoft has created the SDL Threat Modeling Tool. Therefore, modern defense practices have moved to identity. The following are best practices for managing the identity perimeter. Understand PaaS end-to-end application architecture. Starting at the bottom of the stack, the physical infrastructure, Microsoft mitigates common risks and responsibilities. In-house security, on the other hand, is not usually an individual's or a organization's main business and, therefore, may not be as good as that offered by the PaaS Cloud Provider. Security Architecture Best Practices for SaaS Applications. Monitor performance metrics for potential denial-of-service conditions. Best practice: Restrict access based on the need to know and least privilege security principles. Security advantages of a PaaS cloud service model. Many PaaS products include built-in software components that can be integrated into new applications, such as a search function, security features, pre-defined workflows and directory services. Types of Cloud-based delivery Security researchers with skills that cover application hardening are highly sought after and are often hard to source when searching for your candidates.
