SSL certificates are used in web services to authenticate which of the following?
- Both Servers and Clients
- Clients
- Network routers
- Servers
SSL certificates in web services are used to authenticate servers, ensuring that clients are connecting to legitimate and secure servers.
What is the primary purpose of WS-Security in web services?
- Ensuring security in messages
- Handling web service errors
- Improving performance
- Managing session information
WS-Security is primarily used for ensuring security in messages exchanged between web services. It provides a set of specifications that enhance the integrity and confidentiality of the communication, addressing concerns related to authentication, encryption, and the prevention of message tampering.
Which scripting language is commonly exploited in Cross-Site Scripting (XSS) attacks?
- JavaScript
- PHP
- Python
- Ruby
Cross-Site Scripting (XSS) attacks commonly exploit vulnerabilities in JavaScript to inject malicious scripts into web pages.
What is the primary purpose of SSL/TLS in web services?
- Compress data for storage
- Encrypt data transmission
- Speed up data transfer
- Validate HTML code
SSL/TLS in web services is primarily used to encrypt data transmission, ensuring secure communication between clients and servers.
How does implementing idempotent operations in REST APIs enhance the service?
- Enhances security through encryption
- Ensures the same operation has the same effect, even if called multiple times
- Improves response time for non-idempotent operations
- Increases the complexity of the API
Idempotent operations in REST APIs ensure that the same operation has the same effect, even if called multiple times, which aids in reliability and consistency.
What is the role of a resource's representation in REST?
- It defines the resource's data schema
- It determines the resource's security settings
- It represents the current state of the resource and controls its interactions
- It specifies the location of the resource on the server
The representation of a resource in REST encapsulates its current state and governs interactions. This representation can be in various formats like JSON or XML.
The _______ property of XML makes it more suitable for complex data structures.
- Flat
- Hierarchical
- Random
- Sequential
The hierarchical property of XML makes it more suitable for complex data structures. XML allows the creation of nested elements, forming a tree-like structure that can represent intricate relationships and organize data in a way that is both meaningful and versatile.
In AWS, what is the main advantage of using Amazon RDS over installing a database on an EC2 instance?
- Automated database management
- Lower storage capacity
- More control over database configurations
- Reduced network bandwidth
Amazon RDS offers automated database management, handling routine database tasks, and providing a managed service for easier maintenance.
For a web service that needs to ensure backward compatibility with older systems, which data format is more appropriate?
- Avro
- JSON
- XML
- YAML
XML is a suitable data format for ensuring backward compatibility with older systems. Its self-descriptive nature and schema support make it easier to maintain compatibility as systems evolve. XML allows for the inclusion of metadata and versioning information, providing a structured approach to handle changes in data structures over time.
What is SQL Injection primarily used for in cyber attacks?
- Denial of service attacks
- Exploiting social media accounts
- Phishing email attacks
- Unauthorized access to a database
SQL Injection is primarily used for gaining unauthorized access to a database by injecting malicious SQL queries.
