PRACTICE IT NOW TO SHARPEN YOUR CONCEPT AND KNOWLEDGE
1. What is the primary purpose of APIs (Application Programming Interfaces) in the context of data stores?
- To improve server performance
- To enhance data confidentiality
- To enable communication and interaction with data
- To prevent unauthorized access
APIs enable communication and interaction with data stores, allowing applications to access and manipulate data.
2. How does API authentication contribute to security in data store interactions?
- By preventing unauthorized access
- By improving server performance
- By encrypting data during transmission
- By enhancing data confidentiality
API authentication prevents unauthorized access to data stores, ensuring that only authenticated and authorized entities can interact with the API.
3. What is the purpose of API authorization in the context of data stores?
- To prevent unauthorized access
- To enhance data confidentiality
- To improve server performance
- To encrypt data during transmission
API authorization ensures that authenticated users or applications have the necessary permissions to access specific data, preventing unauthorized access.
4. How can improper input validation in API requests lead to security vulnerabilities?
- By enhancing user authentication
- By preventing unauthorized access
- By allowing injection attacks and data manipulation
- By improving server performance
Improper input validation in API requests can lead to injection attacks and data manipulation, compromising the integrity of data.
5. What is the significance of using HTTPS (Hypertext Transfer Protocol Secure) in API communication?
- To prevent unauthorized access
- To encrypt data during transmission
- To improve server performance
- To enhance data confidentiality
HTTPS encrypts data during transmission, ensuring the confidentiality and integrity of data exchanged between the API and client.
6. In the context of API security, what is the purpose of rate limiting?
- To enhance user authentication
- To prevent unauthorized access
- To improve server performance
- To control the rate of API requests and prevent abuse
Rate limiting in API security controls the rate of API requests, preventing abuse and protecting against denial-of-service attacks.
7. How can token-based authentication enhance API security?
- By preventing unauthorized access
- By encrypting data during transmission
- By improving server performance
- By providing secure and temporary access tokens
Token-based authentication in API security provides secure and temporary access tokens, enhancing security by minimizing the exposure of sensitive credentials.
8. What is the potential risk of not using proper API versioning in a web application?
- Enhanced data confidentiality
- Improved server performance
- Breaking changes affecting API consumers
- Preventing unauthorized access
Not using proper API versioning can lead to breaking changes that affect API consumers, potentially causing compatibility issues and security vulnerabilities.
9. How does API logging contribute to security in data store interactions?
- By preventing unauthorized access
- By improving server performance
- By recording and monitoring API activities for analysis
- By encrypting data during transmission
API logging records and monitors API activities for analysis, contributing to security by providing visibility into data store interactions.
10. What role does API encryption play in securing data transmitted between an application and a data store?
- To prevent unauthorized access
- To enhance data confidentiality
- To improve server performance
- To restrict access to sensitive data
API encryption enhances data confidentiality by securing data transmitted between an application and a data store, preventing unauthorized access.
