CSRF attacks primarily target which aspect of a web application?
- Cross-Site Request Forgery
- Cross-Site Scripting
- Session Management
- User Authentication
Cross-Site Request Forgery (CSRF) attacks target the integrity of a web application by forcing the victim to perform unwanted actions without their consent, often leading to actions like changing passwords or making financial transactions.
What is the role of the log_message() function in CodeIgniter?
- It displays messages on the user interface for debugging.
- It logs messages to the console.
- It logs messages to the system log file.
- It sends email notifications for critical errors.
The log_message() function in CodeIgniter is used to log messages to the system log file. It's a handy way to record information or errors for later analysis, especially in production environments where direct debugging may not be possible.
In a multi-developer environment, managing __________ for third-party libraries is crucial for consistent functionality in CodeIgniter applications.
- Collaborations
- Configurations
- Dependencies
- Versions
In a multi-developer environment, managing configurations for third-party libraries is crucial for consistent functionality in CodeIgniter applications. This involves maintaining consistent settings and configurations across different development environments, ensuring that the libraries work uniformly across the team.
Which file in CodeIgniter is used to set up database connection details?
- config.php
- connections.php
- database.php
- db_config.php
In CodeIgniter, the database.php file is used to store and configure database connection details, including hostname, username, password, and database name. This centralizes database settings.
When configuring a CodeIgniter application for a financial service, the first step in enhancing security should focus on ________.
- Enforcing Strict Session Management
- Implementing HTTPS
- Securing Database Connections
- Validating User Inputs
In a financial service, the first step in enhancing security is often to implement HTTPS. This ensures that data transmission between the user's browser and the server is encrypted, reducing the risk of eavesdropping and man-in-the-middle attacks. HTTPS is a fundamental step in securing sensitive financial information.
The CodeIgniter helper function ________ is used to set JSON content type in HTTP headers.
- json_header()
- set_content_type('application/json')
- set_json_content_type()
- set_json_header()
The set_content_type('application/json') helper function is used in CodeIgniter to set the HTTP response headers to indicate that the content being sent is in JSON format.
During a high traffic period, a CodeIgniter application experiences slow response times. To identify the bottleneck, the developer should examine the ________ in the profiler.
- Controller Execution Time
- Database Queries
- Memory Usage
- Query Execution Time
In a high traffic scenario, examining the Controller Execution Time in the profiler helps identify bottlenecks related to the application's controller execution, providing insights into areas causing slow response times.
CodeIgniter's pagination can be integrated with database results using the ________ method from the Model.
- get_pagination()
- initialize_pagination()
- paginate()
- render()
In CodeIgniter, pagination with database results is achieved using the paginate() method. This method helps in generating the necessary pagination links for displaying data across multiple pages.
What are the challenges faced when unit testing CodeIgniter applications that heavily rely on database interactions?
- CodeIgniter applications do not support database testing.
- Database interactions in CodeIgniter do not pose any challenges.
- Database tests in CodeIgniter are always fast and efficient.
- Handling database connections and ensuring a clean state between tests.
Unit testing CodeIgniter applications with heavy database interactions can be challenging due to the need to manage database connections and maintain a clean state between tests. This is crucial to avoid interference between test cases and ensure reliable and accurate results.
How does the Active Record Class handle SQL injection prevention in CodeIgniter?
- By escaping user inputs using the escape() method
- By manually sanitizing input using PHP functions
- By relying on the built-in CodeIgniter firewall
- By using parameterized queries
The Active Record Class in CodeIgniter handles SQL injection prevention by using parameterized queries. This approach ensures that user inputs are treated as data rather than executable code, making it more difficult for malicious SQL injection attacks to occur. It helps prevent the injection of unauthorized SQL code into database queries, enhancing the security of the application.
