The HTTP method _______ is used in RESTful services to request a representation of the specified resource requests without returning the entity-body.
- GET
- HEAD
- POST
- PUT
In RESTful services, the HTTP method HEAD is used to request a representation of the specified resource without returning the entity-body. The server responds with headers containing information about the resource, allowing clients to check its existence and obtain metadata without the actual data.
WS-Security supports _______ as a means of ensuring message integrity.
- HMAC (Hash-based Message Authentication Code)
- OAuth Tokens
- SOAP Headers
- XML Signature
WS-Security leverages XML Signature as a means of ensuring message integrity in web services. XML Signature provides a way to sign parts of XML documents, including SOAP messages, to ensure their authenticity and integrity during transmission. This enhances the overall security of web service communication.
In advanced SOAP services, _______ is used to enhance message integrity and confidentiality.
- OAuth
- SAML
- WS-ReliableMessaging
- WS-Security
WS-Security is an extension to SOAP to provide security features like confidentiality and integrity. It enables the encryption of messages to ensure confidentiality and the use of digital signatures for integrity. This enhances the overall security of advanced SOAP services, especially when sensitive information is transmitted.
Which type of encryption does TLS use to secure data transmission in web services?
- Hashing
- Only Asymmetric Encryption
- Only Symmetric Encryption
- Symmetric and Asymmetric Encryption
TLS (Transport Layer Security) uses a combination of symmetric and asymmetric encryption to secure data transmission. Symmetric encryption for bulk data and asymmetric encryption for key exchange.
What is the role of WSDL in a SOAP web service?
- WSDL defines the security protocols for a web service
- WSDL describes the structure and functionality of a web service
- WSDL handles the actual data transmission in SOAP
- WSDL is not related to SOAP
WSDL (Web Services Description Language) is used in SOAP web services to describe the structure and functionality of the service, including its operations and message formats.
When implementing HTTPS, what type of encryption is typically used?
- AES
- MD5
- RSA
- SSL/TLS
HTTPS typically uses the SSL/TLS protocol for secure communication over the web.
To prevent second-order SQL Injection, it is important to perform input validation at the _______ stage.
- Application
- Database
- Middleware
- Presentation
Input validation at the database stage is crucial to prevent second-order SQL Injection attacks, where malicious data is stored and later used to exploit vulnerabilities.
In a scenario where an application requires rapid scaling based on demand, which feature of Kubernetes is most beneficial?
- Container Registry
- Docker Compose
- Horizontal Pod Autoscaling
- Kubernetes ConfigMaps
Horizontal Pod Autoscaling in Kubernetes allows automatic scaling of the number of pods based on observed CPU utilization or other custom metrics, ensuring optimal resource allocation.
For safe and read-only operations, RESTful services commonly use the _______ method.
- DELETE
- GET
- POST
- PUT
For safe and read-only operations in RESTful services, the GET method is commonly used. The GET method requests data from a specified resource and should not cause any side effects on the server. It is suitable for operations where data retrieval is the primary goal.
What role does SOC 2 play in the compliance of web services?
- Assessing Service Organization Controls
- Certifying Open Source Components
- Optimizing Server Configuration
- Standardizing Object-oriented Code
SOC 2 plays a crucial role in web services compliance by assessing and ensuring the effectiveness of service organization controls related to security, availability, processing integrity, confidentiality, and privacy.
