Introduction
At Amazon Web Services (AWS), our foremost commitment is to cloud security. We offer a comprehensive suite of over 200 security, compliance, and governance services and features. This extensive toolkit ensures that a diverse range of customers — from large enterprises to startups — can confidently trust in our capabilities to safeguard their workloads.
In this series of articles, we will explore the security controls provided by AWS Serverless services and demonstrate how their built-in features can help you meet security and compliance standards. In this post, I will discuss the advantages of serverless architectures, emphasizing the shared security model associated with these applications. I will also highlight specific roles — including Developers, DevOps engineers, and Compliance teams — tasked with ensuring the secure deployment and management of serverless applications.
What is Serverless?
Serverless computing represents the cloud’s native architecture, enabling businesses to transfer many operational responsibilities to their cloud provider, such as AWS. This shift enhances agility and fosters innovation. Serverless allows developers to create and run applications without managing servers. It removes tasks like server provisioning, patching, and operating system maintenance, allowing you to focus on building applications that are scalable and available.
The four primary benefits of serverless include:
- No server management
- Flexible scaling
- Pay for what you use
- Automated high availability
Shared Security Model
In the realm of serverless computing, security and compliance responsibilities are shared between AWS and you, the customer. AWS provides a secure data center and network architecture that meets the highest security requirements, while it is responsible for safeguarding the infrastructure supporting all AWS services. Regular audits by third-party assessors validate our security effectiveness within the framework of AWS compliance programs. Your security obligations depend on the AWS services you utilize, alongside other factors such as data sensitivity, company policies, and applicable laws. This concept is referred to as “security in the cloud.”
With serverless architectures, customers can concentrate on several key areas: securing application code, managing the storage and accessibility of sensitive data, monitoring application behavior through logging, and implementing identity and access management (IAM) for relevant services.
Pay close attention to the responsibilities regarding platform management, code encryption, network traffic, firewall configuration, and operating system/network setup. While AWS handles these aspects for serverless architectures, they remain essential for non-serverless environments.
Security Personas
If you have experience with server-based applications, consider these points to better grasp how serverless alters your security practices:
- Compliance teams must recognize AWS’s increased security responsibilities in serverless applications, understand which services adhere to compliance standards, and identify any necessary configurations to maintain compliance.
- DevOps teams should utilize available protective and detective controls to securely deploy and manage serverless applications.
- Developers need to practice least privilege access and handle sensitive data appropriately in their applications.

Conclusion
In conclusion, serverless architecture presents immense advantages, but it also requires a shift in how security is approached. By understanding the shared responsibilities and focusing on the critical areas of security, organizations can leverage serverless technologies effectively and securely.
