The document discusses APIs and their importance, particularly focusing on API security threats such as injection attacks, broken authentication, and sensitive data exposure. It outlines best practices for securing APIs, including authentication methods like OAuth 2.0, using encryption, input validation, rate limiting, and monitoring through logging. Additionally, it mentions tools and technologies for API management and highlights specific vulnerabilities, including Bluetooth vulnerabilities like Blueborne.

2. What is an API?

3. What is an API?
Different Software Systems

4. Why is API Security Important?
Facebook-Cambridge Analytica Scandal

5. Common API Security Threats
Injection Attacks
An attacker inserts malicious code into an API request
'; DROP TABLE users; --

6. Common API Security Threats
Broken Authentication
If an API uses predictable tokens, hackers can guess them and
gain unauthorized access

7. Common API Security Threats
Sensitive Data Exposure
If your API sends data without proper encryption, anyone who
intercepts it can see the data

8. Common API Security Threats
Rate Limiting and DDoS Attacks
Attackers flood your API with so many requests that it crashes or
becomes unresponsive

9. Common API Security Threats
Man-in-the-Middle Attacks
Attackers create fake APIs to trick users into providing sensitive data

10. Common API Security Threats
API Spoofing
If an attacker intercepts the communication between your API and the
client, they can read or modify the
data being transmitted

11. Best Practices for Securing APIs
Authentication and Authorization
Think of OAuth 2.0 as a special access pass that only authorized users can
get
It ensures that only users with the right pass can access the data
OpenID Connect adds an extra layer by verifying the user’s identity
Comparing API keys to basic passwords, tokens are more secure

12. Best Practices for Securing APIs
Encryption
Always use HTTPS, which is like sending locked packages that only the
recipient can open
Encrypt sensitive data at rest, just like storing valuables in a safe, to protect it
from unauthorized access

13. Best Practices for Securing APIs
Input Validation
Always clean user inputs to prevent malicious data from sneaking in
If a user enters a script tag <script>, sanitize it to prevent XSS (Cross-Site
Scripting) attacks

14. Best Practices for Securing APIs
Rate Limiting and Throttling
It’s like setting a limit on how many times someone can knock on your door
Tools like Cloudflare can help filter out malicious traffic and keep your API
running smoothly, protecting against DDoS attacks

15. Best Practices for Securing APIs
Logging and Monitoring
Keep a record of all API requests to spot unusual activity. It’s like having a
CCTV camera to monitor who’s coming and going
Tools like Prometheus and Grafana can help you monitor API health and alert
you to potential issues

16. Best Practices for Securing APIs
API Gateway and Security
Keep a record of all API requests to spot unusual activity. It’s like having a
CCTV camera to monitor who’s coming and going
Tools like Prometheus and Grafana can help you monitor API health and alert
you to potential issues

17. Tools and Technologies
OWASP ZAP
Postman Burp Suite

18. API Management Platforms
AWS API Gateway
Apigee Azure API Management

19. What is an API?
Convenient Connectivity
IoT Integration
Health and Fitness
Automotive Industry

20. Types of Bluetooth Vulnerabilities
BlueBorne
This vulnerability allows attackers to take control of
Bluetooth-enabled devices without the need for pairing or
user interaction
It can enable remote code execution, data theft, and the
spread of malware across devices
