Authentication: API endpoints should require authentication to ensure that only authorized users can access them. This can be done through mechanisms such as tokens, API keys, or OAuth.
Authorization: In addition to authentication, APIs should also employ authorization mechanisms to ensure that authenticated users can only access the data and resources that they are authorized to access.
Encryption: Sensitive data should be encrypted both in transit and at rest to prevent unauthorized access and protect data integrity.
Rate limiting: APIs should implement rate limiting to prevent denial-of-service (DoS) attacks, where attackers flood the API with requests to overwhelm the system and cause a disruption.
Input validation: APIs should validate input data to prevent injection attacks and ensure that only valid data is accepted.
Regular testing: Regular security testing of API endpoints can help detect vulnerabilities and enable prompt remediation before they can be exploited.
Monitoring and logging: Real-time monitoring and logging of API activity can help detect and respond to suspicious behavior, including potential attacks, and enable effective incident response.
