AWS follows a shared security responsibility model, where they secure their infrastructure and the customer is responsible for securing their data and applications. The customer must understand the demarcation line between AWS's responsibilities and their own to properly secure their apps on AWS. Security in the cloud includes protecting customer data, implementing encryption, and enabling identity and access management (IAM). To establish security in the cloud, customers should prioritize data security, implement IAM controls, configure operating systems and networks, and use robust firewalls. The Snyk platform can help teams secure their application side of the cloud environment by automating security controls across the SDLC, providing centralized security intelligence and flexible governance, and integrating with AWS services such as Amazon Inspector, AWS Security Hub, and AWS CloudTrail Lake.
