What role does SNI (Server Name Indication) play in TLS for web services?
- Allows a client to indicate the hostname it is attempting to connect to during the TLS handshake process
- Enables secure key exchange between client and server
- Facilitates secure data transmission between servers
- Provides encryption for server certificates
SNI allows a client to indicate the hostname during the TLS handshake, allowing servers to present the appropriate certificate for the requested domain.
How does UDDI support the concept of SOA (Service-Oriented Architecture)?
- Data Storage and Retrieval
- Security Enforcement
- Service Publication and Discovery
- Transaction Management
UDDI supports the concept of SOA by enabling service publication and discovery. It provides a standardized way for services to be published, discovered, and consumed, promoting the key principles of Service-Oriented Architecture (SOA) such as reusability, interoperability, and flexibility.
What is the significant difference between SAML and OAuth in authentication processes?
- OAuth focuses on user authentication, while SAML focuses on data encryption
- OAuth is a markup language, while SAML is a protocol
- SAML is primarily used for single sign-on (SSO), while OAuth is an authorization framework for granting access
- SAML is used exclusively in mobile applications, while OAuth is used in web applications
SAML is commonly used for single sign-on (SSO), providing a way to authenticate users across multiple applications. OAuth, on the other hand, is primarily an authorization framework for granting access to resources.
