Fundamentals of Secure Software - API Security

The video tutorial covers API security, starting with an introduction to APIs and their modular nature. It explains the OWASP API security top ten, detailing risks like broken object level authorization, broken authentication, excessive data exposure, and more. Each risk is explained with examples and prevention methods. The tutorial emphasizes the importance of proper configuration, asset management, and logging to ensure API security.

What is the primary advantage of using APIs in application development?

• They make applications monolithic.

• They allow for modular application development.

• They reduce the need for web servers.

• They increase the complexity of applications.

Which of the following is NOT a part of the OWASP API Security Top Ten?

• Excessive data exposure

• Improper asset management

• Broken object level authorization

• Secure data encryption

What is a common prevention method for broken authentication in APIs?

• Using weak passwords

• Implementing strong password reset APIs

• Reusing API keys

• Ignoring token validation

How can excessive data exposure be prevented in APIs?

• By relying on the client to filter data

• By allowing direct access to sensitive data

• By returning full data objects

• By tailoring API responses to customer needs

What is a key prevention strategy for security misconfiguration in APIs?

• Exposing all system files

• Allowing verbose error messages

• Disabling unnecessary features

• Using default configurations

Which of the following describes an injection attack?

• An attacker uses weak authentication

• An attacker substitutes IDs in an API call

• An attacker constructs API calls with SQL commands

• An attacker performs a DDoS attack

What is a recommended practice for managing old and non-production API versions?

• Keeping them publicly accessible

• Ignoring them as they are not in use

• Properly inventorying and decommissioning them

• Allowing them to access production data
