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.
For tracking memory usage and execution time, CodeIgniter developers often use ______ markers.
- Benchmark
- Logger
- Profiler
- Trace
CodeIgniter's Profiler class allows developers to mark specific points in the code to track memory usage and execution time. These markers aid in performance analysis and optimization.
What is the primary security concern when allowing file uploads in a web application?
- Allowing unauthorized access to user data
- Executing malicious scripts through file uploads
- Exposing the server's file structure
- Overloading the server with excessive file uploads
The primary concern is the risk of executing malicious scripts through file uploads. By allowing users to upload files, there is a potential threat of uploading files containing scripts that can harm the application and compromise security. Proper validation and filtering are essential to mitigate this risk.
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.
The use of ________ in CodeIgniter is essential for integrating custom Helpers with core functionalities.
- Configurations
- Extensions
- Register
- autoload
The use of autoload in CodeIgniter is essential for integrating custom Helpers with core functionalities. This allows them to be loaded automatically.
