Application Security in the AWS Cloud


What is Application Security?

Application security describes application-level security measures designed to prevent theft of data and code within an application, or compromise of the application and its host environment. It includes security considerations that arise during application development and design, as well as systems and methods for securing applications after deployment.

Application security can include hardware, software, and procedures to identify or minimize security gaps. Application-level security measures are most commonly delivered via software solutions. For example, web application firewalls clearly define allowed and forbidden activities for application traffic. Security procedures can include things like application security routines, including periodic security testing.

The Need For Cloud Application Security

Cloud application security is a system of policies, processes, and controls that enable enterprises to protect applications and data in collaborative cloud environments.

Modern enterprise workloads are distributed across a variety of cloud platforms, from SaaS suites to custom cloud-native applications running on multiple hyperscale cloud service providers.

As a result, network perimeters are more dynamic than ever, and critical data and workloads face threats that did not exist 10 years ago. Businesses need to protect their workloads wherever they run. Cloud computing can also introduce new challenges to data sovereignty and data governance and complicate compliance.

Application Security in the AWS Cloud

Amazon Web Services (AWS) is the world's leading cloud provider. It provides a range of tools and services that provide control over the AWS environment. These services help network and application security teams meet specific protection and compliance requirements in the Amazon cloud, providing protection at the host, network, and application level.

AWS Security Hub

AWS Security Hub provides a comprehensive view of your AWS security posture and compliance with security standards and best practices. AWS Security Hub centralizes and prioritizes security findings from AWS accounts, services, and supported third-party partners, analyzes security trends, and identifies top-priority security issues.
