# Awesome API Security Essentials
## 🚀 About the Project
As more applications rely on APIs for communication and data exchange, ensuring their security is crucial to prevent unauthorized access, data breaches, and service disruptions. The "Awesome API Security Essentials" project aims to be a one-stop resource for developers, providing them with everything they need to implement comprehensive API security measures.
It provides:
- **Comprehensive API security resources** - articles, tutorials, and whitepapers
- **Curated tools, libraries, and frameworks** for implementation and testing
- **Best practices, guidelines, and recommendations** for secure API design
- **Community-driven contributions and updates** for continuous improvement
- **Detailed explanations and use cases** for better understanding and application

## 🎳 OWASP API Top 10 2023
| **OWASP API Top 10 - 2023** | **Why?** |
|----------------------------------------------------------------------------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------|
| [API1:2023 - Broken Object Level Authorization](https://owasp.org/API-Security/editions/2023/en/0xa1-broken-object-level-authorization/) | API endpoints often expose object identifiers, which can be manipulated by unauthorized users. It's critical to verify permissions for each request. |
| [API2:2023 - Broken Authentication](https://owasp.org/API-Security/editions/2023/en/0xa2-broken-authentication/) | If authentication is implemented poorly, attackers can hijack user sessions or impersonate users. Always verify the user's identity in a secure way. |
| [API3:2023 - Broken Object Property Level Authorization](https://owasp.org/API-Security/editions/2023/en/0xa3-broken-object-property-level-authorization/) | APIs must also verify permissions for individual object properties. Without this, attackers can access or manipulate data they shouldn't have access to. |
| [API4:2023 - Unrestricted Resource Consumption](https://owasp.org/API-Security/editions/2023/en/0xa4-unrestricted-resource-consumption/) | APIs need to handle resource limitations effectively. If not managed properly, excessive requests can lead to service outages or increased operational costs. |
| [API5:2023 - Broken Function Level Authorization](https://owasp.org/API-Security/editions/2023/en/0xa5-broken-function-level-authorization/) | APIs must manage user roles and permissions correctly. If not, users could gain unauthorized access to certain functionalities. |
| [API6:2023 - Unrestricted Access to Sensitive Business Flows](https://owasp.org/API-Security/editions/2023/en/0xa6-unrestricted-access-to-sensitive-business-flows/) | APIs should protect business operations. Without protection, automated or excessive usage of business functionalities could cause damage. |
| [API7:2023 - Server Side Request Forgery](https://owasp.org/API-Security/editions/2023/en/0xa7-server-side-request-forgery/) | APIs must validate external resource requests to prevent attackers from forcing the server to send requests to unauthorized locations. |
| [API8:2023 - Security Misconfiguration](https://owasp.org/API-Security/editions/2023/en/0xa8-security-misconfiguration/) | API settings should be configured properly. Neglecting to do so can leave vulnerabilities that attackers can exploit. |
| [API9:2023 - Improper Inventory Management](https://owasp.org/API-Security/editions/2023/en/0xa9-improper-inventory-management/) | APIs must maintain accurate and updated documentation of all available endpoints to prevent the exposure of deprecated or debug endpoints. |
| [API10:2023 - Unsafe Consumption of APIs](https://owasp.org/API-Security/editions/2023/en/0xaa-unsafe-consumption-of-apis/) | Developers should be careful when using third-party APIs and not trust them blindly. Attackers could exploit these third-party services to compromise your API. |

## ⚔️ OWASP API Top 10 2019 vs OWASP API Top 10 2023
| **OWASP API Top 10 2019** | **OWASP API Top 10 2023** | **Changes** |
|-------------------------------------------------|-------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| API1:2019 - Broken Object Level Authorization | API1:2023 - Broken Object Level Authorization | No significant changes, both versions focus on issues related to object identifiers and object level access control. |
| API2:2019 - Broken User Authentication | API2:2023 - Broken Authentication | Slight changes in the naming, but the core issue remains the same - problems with the implementation of authentication mechanisms. |
| API3:2019 - Excessive Data Exposure | API3:2023 - Broken Object Property Level Authorization | The 2023 issue combines the 2019 Excessive Data Exposure and 2019 Mass Assignment to focus on authorization validation at the object property level. |
| API4:2019 - Lack of Resources & Rate Limiting | API4:2023 - Unrestricted Resource Consumption | Similar focus on resource consumption but the 2023 version adds the aspect of resources made available by third-party API integrations. |
| API5:2019 - Broken Function Level Authorization | API5:2023 - Broken Function Level Authorization | No significant changes, both versions focus on the issues with access control policies and different user roles. |
| API6:2019 - Mass Assignment | API6:2023 - Unrestricted Access to Sensitive Business Flows | The 2023 version expands the focus to include the harm to business from automated excessive use of a function, not necessarily resulting from implementation bugs. |
| API7:2019 - Security Misconfiguration | API7:2023 - Server Side Request Forgery | The 2023 version focuses on a specific type of attack – Server-Side Request Forgery (SSRF), while the 2019 version had a broader focus on various misconfigurations. |
| API8:2019 - Injection | API8:2023 - Security Misconfiguration | The 2023 version shifts the Security Misconfiguration from 2019's API7, highlighting the issues related to configurations and best practices, while 2019's API8 was about various types of injection attacks. |
| API9:2019 - Improper Assets Management | API9:2023 - Improper Inventory Management | Both versions stress the importance of proper documentation and inventory of hosts and deployed API versions. The naming was changed to more accurately reflect the main concern. |
| API10:2019 - Insufficient Logging & Monitoring | API10:2023 - Unsafe Consumption of APIs | The 2023 version brings a new concern about trusting third-party APIs and weaker security standards, while the 2019 version focused on logging, monitoring, and incident response. |
