In CodeIgniter, the setting $config['sess_ ________'] can be used to enable session encryption for added security.
- encrypt_sessions
- encryption
- secure_encrypt
- session_encrypt
The setting $config['sess_encryption'] in CodeIgniter can be used to enable session encryption. When set to on, it encrypts the session data for added security. This is particularly useful when dealing with sensitive information in the session, providing an additional layer of protection against unauthorized access.
What is the concept of 'exception propagation' in error handling?
- Propagation allows an exception to travel up the call stack until it is caught by an appropriate catch block.
- Propagation is a feature in CodeIgniter that automatically logs exceptions.
- Propagation is the process of creating custom exceptions in CodeIgniter.
- Propagation refers to the automatic handling of exceptions by the PHP interpreter.
Exception propagation in CodeIgniter involves allowing an exception to move up the call stack until it encounters a suitable catch block. This mechanism helps in centralized handling of exceptions at higher levels, enhancing code maintainability.
During a penetration test, it's found that a script from an external domain is executing malicious actions. This indicates a potential ________ vulnerability.
- Cross-Origin Resource Sharing (CORS)
- Cross-Site Request Forgery (CSRF)
- Cross-Site Scripting (XSS)
- SQL Injection
The presence of a script from an external domain executing malicious actions suggests a Cross-Site Scripting (XSS) vulnerability, where untrusted data is rendered without proper validation or escaping.
In a multi-step form, ensuring that each step is validated before proceeding to the next is an example of ________ validation.
- Front-to-back
- Incremental
- Sequential
- Step-wise
Sequential validation ensures that each step is validated before moving to the next. It ensures data integrity throughout the form submission process.
In a multi-threaded application, an exception in one thread should be handled in a way that ________.
- Does not affect other threads
- Pauses all threads until resolved
- Prompts the user for a resolution
- Terminates the entire application
Handling an exception in a way that does not affect other threads is essential in a multi-threaded application. Pausing or terminating the entire application is generally not recommended as it could disrupt other threads and impact the overall application stability.
Database ________ is a process of inserting initial data into the database for testing purposes.
- Insertion
- Populating
- Seeding
- Seeding:insert
Database Seeding is the process of inserting initial data into the database for testing purposes. It helps to populate the database with dummy data for testing and development.
When storing sessions in a database in CodeIgniter, the table must have a column named ________ to store session data.
- data
- session_content
- session_data
- session_payload
CodeIgniter expects a column named session_data to store session information when using a database to store sessions. The framework uses this column to store serialized session data securely. It is crucial to have this column named correctly for CodeIgniter to work seamlessly with database-backed sessions.
In CodeIgniter, data passed to the view are accessible as ________ variables.
- Controller
- Global
- Local
- View
In CodeIgniter, the data passed to the view is accessible as global variables. These variables are directly accessible in the view file without any prefix, making it convenient to display the data.
How does Test Driven Development (TDD) approach integrate with CodeIgniter's unit testing?
- CodeIgniter provides built-in support for TDD, allowing developers to write tests before the actual code.
- CodeIgniter's unit testing is a separate process from TDD.
- TDD is not supported in CodeIgniter.
- TDD is only suitable for other PHP frameworks.
CodeIgniter supports Test Driven Development by facilitating the creation of tests before the implementation of code. This promotes a more robust and reliable development process by ensuring that the code meets the specified requirements from the outset.
In what scenario is it advisable to use the escape methods in CodeIgniter's Query Builder?
- When building queries without the need for variable interpolation
- When dealing with static data that doesn't change frequently
- When incorporating user input into SQL queries to prevent SQL injection
- When performing read-only operations on the database
It's advisable to use escape methods in CodeIgniter's Query Builder when incorporating user input to prevent SQL injection and enhance security.
