_______ vulnerability arises when an application includes untrusted data in a new web page without proper validation.
- Clickjacking
- Cross-Site Request Forgery (CSRF)
- Cross-Site Scripting (XSS)
- SQL Injection
Cross-Site Scripting (XSS) vulnerability occurs when untrusted data is included in a web page without proper validation, allowing malicious scripts to be executed.
The process of finding suitable web services in UDDI is known as _______.
- UDDIsearch
- serviceDiscovery
- serviceMatching
- webServiceIdentification
The process of finding suitable web services in UDDI is known as serviceMatching. During service matching, UDDI compares the technical and business criteria provided by the requester with the information stored in the registry to identify and return relevant services.
A web application suffers a data breach due to an SQL Injection. Which aspect of security was most likely overlooked?
- Authentication
- Encryption
- Input validation
- Session management
The data breach due to SQL Injection indicates a lack of proper input validation, allowing malicious SQL queries to be executed.
In a scenario where a web service handles sensitive data, what TLS feature should be prioritized to prevent data breaches?
- Heartbeat Extension
- Perfect Forward Secrecy
- SSLv2 Compatibility
- Session Resumption
Prioritize Perfect Forward Secrecy (PFS) to ensure that even if a long-term key is compromised, past communication remains secure.
_______ is used in web services to describe the data structure in a detailed manner.
- HTML
- JSON
- XML
- YAML
XML is commonly used in web services to describe the data structure in a detailed and standardized manner, facilitating data interchange between systems.
Which security consideration is most critical when implementing OAuth in a web service?
- Allowing unlimited token validity periods
- Properly validating and securing access tokens
- Storing user credentials in plaintext
- Using plaintext for token transmission
The most critical security consideration in implementing OAuth is properly validating and securing access tokens. Access tokens are a key component in OAuth, and ensuring their integrity and validity is crucial for preventing unauthorized access. This involves token validation, protection against token leakage, and secure handling of tokens throughout the authentication process.
In a Continuous Integration/Continuous Deployment (CI/CD) pipeline, how do mock services enhance the testing process?
- Automating database migrations
- Enabling parallel testing
- Enhancing user interface design
- Reducing dependencies on external services
Mock services enhance the testing process in CI/CD pipelines by reducing dependencies on external services, enabling faster and more reliable testing without relying on the availability of real services.
In UDDI, the 'bindingTemplate' is crucial for:
- Defining security policies
- Describing how to access a service
- Managing service dependencies
- Specifying service ownership
In UDDI, the 'bindingTemplate' is crucial for describing how to access a service. It contains information about the technical details needed to interact with a web service, such as the access point and transport protocol. This information is essential for service consumers to correctly communicate with and utilize the functionality offered by the service.
What mechanism does SOAP use for error handling in web services?
- Custom error headers
- Exception objects in the application code
- Fault element in the SOAP body
- HTTP status codes
SOAP uses the Fault element within the SOAP body to convey error information. This allows for standardized error handling in web services.
What role does contract testing play in integration testing of web services?
- Only applicable in monolithic architectures
- Testing individual services in isolation
- Validating user interfaces
- Verifying agreements between services
Contract testing involves verifying the contracts or agreements between services, ensuring they interact as expected.
What is the primary objective of performance testing in web services?
- Analyzing database structure
- Assessing system responsiveness and stability under varying loads
- Checking code syntax errors
- Designing user interfaces
Performance testing in web services aims to evaluate system responsiveness and stability under different loads, ensuring optimal performance.
In a scenario where API endpoints change frequently, how can Postman assist in maintaining test accuracy?
- Change the test scripts each time
- Rely on manual testing
- Update the documentation only
- Use variables and environments
Postman allows the use of variables and environments, helping maintain test accuracy even when API endpoints change frequently.
