📌 Serverless Security Models Summary
Serverless security models refer to the methods and best practices used to protect applications built using serverless computing platforms. In serverless architecture, developers write code that runs in short-lived, stateless functions managed by a cloud provider, rather than on traditional servers. Security responsibilities are shared between the cloud provider, who secures the infrastructure, and the developer, who must secure their application code and configurations. Serverless security models help ensure that data, functions, and workflows remain safe from threats like unauthorised access, code injection, and misconfiguration.
🙋🏻♂️ Explain Serverless Security Models Simply
Imagine you are renting a room in a hotel. The hotel owner takes care of the building’s security, but you must lock your own door and keep your valuables safe. Serverless security works in a similar way: the cloud provider protects the building, and you are responsible for what happens inside your room, like your code and data.
📅 How Can it be used?
Serverless security models help protect user data and prevent unauthorised access in cloud-based event-driven web applications.
🗺️ Real World Examples
A company uses AWS Lambda functions to process online orders. They apply a serverless security model by setting strict permissions on their functions, encrypting sensitive data, and monitoring logs for unusual activity to prevent data leaks or unauthorised access.
A fintech startup builds a chatbot using Azure Functions to handle customer queries. They implement serverless security by validating all user input, using secure API gateways, and ensuring each function has only the necessary permissions to access financial data.
✅ FAQ
What is a serverless security model and why does it matter?
A serverless security model is a set of guidelines and methods designed to keep applications safe when using serverless platforms. Since the cloud provider manages the servers, developers focus more on securing their own code and settings. This matters because, even though some security is handled for you, mistakes in your code or settings could still leave your application open to threats.
Who is responsible for security in serverless computing?
Security in serverless computing is a shared responsibility. The cloud provider takes care of the infrastructure, like the servers and networking, while the developer is responsible for securing the actual application, including the code, permissions, and how data is handled. Both sides need to do their part to keep everything safe.
What are common threats to serverless applications?
Common threats to serverless applications include unauthorised access, code injection, and misconfigurations. Because serverless apps often connect to other services and handle sensitive data, any weak spot in the code or settings can be an easy target for attackers. Keeping everything up to date and following best practices helps reduce these risks.

Cloud Cost Frameworks
Cloud cost frameworks are structured approaches that help organisations understand, manage, and optimise the expenses related to their use of cloud services. These frameworks provide guidelines and methods for tracking spending, allocating costs to different teams or projects, and identifying areas where savings can be made. By using a cloud cost framework, businesses can make informed decisions about their cloud investments, ensuring they get value for money and avoid unexpected bills.
DevSecOps Automation
DevSecOps automation is the practice of integrating security checks and processes directly into the automated workflows of software development and IT operations. Instead of treating security as a separate phase, it becomes a continuous part of building, testing, and deploying software. This approach helps teams find and fix security issues early, reducing risks and improving the overall quality of software.
OAuth Vulnerabilities
OAuth vulnerabilities are security weaknesses that can occur in applications or systems using the OAuth protocol for authorising user access. These flaws might let attackers bypass permissions, steal access tokens, or impersonate users. Common vulnerabilities include improper redirect URI validation, weak token storage, and insufficient user consent checks.
Feature Engineering
Feature engineering is the process of transforming raw data into meaningful inputs that improve the performance of machine learning models. It involves selecting, modifying, or creating new variables, known as features, that help algorithms understand patterns in the data. Good feature engineering can make a significant difference in how well a model predicts outcomes or classifies information.
Compliance in Transformation
Compliance in transformation refers to ensuring that changes within an organisation, such as adopting new technologies or processes, meet all relevant legal, regulatory and internal policy requirements. It involves identifying what rules and standards must be followed during a transformation project and making sure these are built into the planning and execution stages. This helps avoid legal issues, financial penalties and reputational damage while supporting smooth change.
