In a recent security breach, an SQL injection attack was used to access sensitive data. The initial investigation should focus on the ________ used in the application.
- Authentication protocols
- Coding languages
- Database queries
- Encryption algorithms
The initial investigation should focus on the database queries used in the application. SQL injection attacks exploit vulnerabilities in the construction of database queries, allowing attackers to manipulate or retrieve sensitive data. Analyzing and securing the database queries is crucial in addressing and preventing such security breaches.
A developer is setting up a new CodeIgniter project on a shared hosting. The first step they should take for configuration is to adjust the ________.
- Application Language Configuration
- Database Configuration
- Server Environment Configuration
- URL Routing Configuration
When setting up a CodeIgniter project on shared hosting, adjusting the server environment configuration is crucial. This includes setting the base URL, index page, and other server-related settings in the config.php file to match the hosting environment.
In CodeIgniter, API rate limiting is often implemented using ________.
- Limit.php
- Rate.php
- Ratelimiter.php
- Throttling.php
CodeIgniter implements API rate limiting through the 'Limit.php' library, allowing developers to control the number of requests a user can make to the API over a specific period.
In CodeIgniter, what is the recommended approach to secure JSON and XML API endpoints?
- Applying API keys and securing with a token-based system
- Enabling CSRF protection and validating inputs
- Implementing OAuth for API authentication
- Using SSL/TLS for secure data transmission
The recommended approach in CodeIgniter to secure JSON and XML API endpoints is by applying API keys and implementing a token-based system. This helps in authenticating and authorizing requests, ensuring secure communication between clients and the API endpoints.
To view detailed benchmarking data in CodeIgniter, the ________ method must be enabled in the controller.
- _output()
- benchmark()
- display()
- render()
In CodeIgniter, the benchmark() method is used to view detailed benchmarking data. This function is commonly used to measure the time taken by specific parts of your code for performance analysis.
The assertion method used to check if a function returns a boolean true is called ________.
- assert_bool
- assert_boolean
- assert_true
- assert_truthy
In CodeIgniter, the assertTrue method in PHPUnit is used to assert that a certain expression evaluates to true. This is commonly used to verify that a function returns a boolean true value.
Advanced XSS protections often involve the use of ________, which restricts scripts based on their source and inline script execution.
- Content Security Policy (CSP)
- Cross-Origin Resource Sharing (CORS)
- Cross-Site Request Forgery (CSRF)
- Cross-Site Scripting (XSS)
Content Security Policy (CSP) is a security standard that helps prevent XSS by defining trusted sources for content. This restricts scripts based on their source and inline script execution.
In a scenario where a CodeIgniter application needs to switch databases based on user roles, the database switching is typically done in the ________.
- Controller
- Database Configuration
- Model
- View
In CodeIgniter, database switching based on user roles is typically done in the Database Configuration file. This file allows you to set different database connections and switch between them based on your application's requirements.
Describe the process of using breakpoints in CodeIgniter for debugging complex issues.
- Adding break() function in code
- Breakpoints are not supported in CodeIgniter
- Configuring breakpoints in config.php
- Setting breakpoints in the IDE
Breakpoints in CodeIgniter are set within the IDE, allowing developers to pause execution at specific lines. This powerful debugging technique helps examine variable values, trace program flow, and identify and resolve complex issues efficiently.
To reduce the server response time in a CodeIgniter application, one effective strategy is to optimize ________.
- CSS Styling
- Database Queries
- Front-end Templates
- JavaScript Functions
Optimizing database queries is crucial for reducing server response time. By analyzing and optimizing SQL queries, developers can minimize database load, resulting in faster response times for CodeIgniter applications.
