📌 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

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.

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.

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.

💡Other Useful Knowledge Cards

Kerberos Exploitation

Kerberos exploitation refers to techniques used by attackers to abuse weaknesses or misconfigurations in the Kerberos authentication protocol. Kerberos is widely used in Windows environments to manage secure logins and resource access. Attackers can exploit vulnerabilities to gain unauthorised access, impersonate users, or escalate their privileges within a network.

Data Governance Frameworks

A data governance framework is a set of rules, processes and responsibilities that organisations use to manage their data. It helps ensure that data is accurate, secure, and used consistently across the business. The framework typically covers who can access data, how it is stored, and how it should be handled to meet legal and ethical standards.

Shadow IT Identification

Shadow IT Identification is the process of finding and tracking technology systems, software, or devices that are used within an organisation without official approval or oversight. These tools are often adopted by employees to solve immediate problems or increase productivity, but they can create security and compliance risks if not properly managed. Identifying shadow IT helps organisations maintain control over data, ensure security standards are met, and avoid unnecessary costs.

Cloud Migration

Cloud migration is the process of moving digital assets such as data, applications, and IT resources from on-premises infrastructure to cloud-based services. This shift aims to take advantage of benefits like increased flexibility, scalability, and cost savings. It often involves careful planning to ensure that systems work smoothly in the new environment and that data is transferred securely.

Smart Contract Security

Smart contract security refers to the practice of protecting digital agreements that run automatically on blockchain networks. These contracts are made of computer code and control assets or enforce rules, so any errors or weaknesses can lead to lost funds or unintended actions. Security involves careful coding, testing, and reviewing to prevent bugs, hacks, and misuse.
