In an audit, a security expert discovers that a web application is vulnerable to CSRF. The most likely missing security measure is ________.
- Anti-CSRF Tokens
- HTTPS Encryption
- Input Validation
- Session Tokens
Cross-Site Request Forgery (CSRF) is an attack where an attacker tricks the victim's browser into performing an undesired action. To prevent CSRF, web applications commonly use anti-CSRF tokens that are unique per user session. This helps ensure that the request originates from the legitimate user.
Choosing between 'Active Record' and standard SQL in CodeIgniter impacts performance by:
- Active Record is always faster than standard SQL
- Active Record is suitable only for simple queries
- Active Record tends to be slower for complex queries
- Standard SQL is more flexible and performs better
Choosing between 'Active Record' and standard SQL in CodeIgniter impacts performance by: Standard SQL is more flexible and generally performs better for complex queries. While Active Record is convenient for simple queries, it may introduce additional overhead for more intricate database operations. Developers need to consider the nature of the queries and the performance requirements when making this choice.
An application developer implements a new input validation library to secure against SQL injection. The effectiveness of this library is best tested by _________.
- Attempting SQL injection attacks
- Conducting code reviews
- Performing penetration testing
- Running security scans
The effectiveness of the input validation library is best tested by attempting SQL injection attacks. This involves trying various injection techniques to ensure that the implemented input validation successfully blocks unauthorized SQL code injections, enhancing the application's security.
When implementing a financial transaction feature, the developer uses ________ in CodeIgniter to ensure atomicity and consistency of the database.
- Database Migrations
- Database Transactions
- Input Class
- Security Class
Database Transactions in CodeIgniter are crucial for ensuring the atomicity and consistency of the database, especially in scenarios like financial transactions. By wrapping the related database operations within a transaction, the developer ensures that either all changes are committed or none, preventing data inconsistencies in case of errors or failures.
In a CodeIgniter project, a custom encryption library is introduced. To ensure seamless integration, the developer must consider ________.
- Adding the library to the autoload.php file
- Configuring encryption settings in config.php
- Placing the library in the models directory
- Replacing the built-in encryption library
To ensure seamless integration of a custom encryption library, developers should configure encryption settings in the config.php file. This allows for centralized management of encryption parameters and ensures that the custom library functions correctly within the CodeIgniter project.
During a security audit, it's discovered that large file uploads are causing server crashes. This issue relates to ________.
- Cross-Site Scripting (XSS)
- Denial of Service (DoS) Attacks
- Resource Limitations
- SQL Injection
Server crashes due to large file uploads typically point to resource limitations such as exceeding upload size limits. Managing server resources is crucial to prevent performance issues and potential crashes.
________ exceptions are used to handle errors that are recoverable during runtime.
- Checked
- Custom
- Fatal
- Unchecked
Checked exceptions are used to handle errors that are recoverable during runtime. These exceptions must be explicitly caught or declared by the method.
To optimize a CodeIgniter application's performance, a developer focuses on the sections with the longest execution time in the ________ report.
- Benchmark
- Error Handling
- Profiler
- Routing
The Benchmark report in CodeIgniter highlights the execution time of different sections, allowing developers to identify and optimize areas with the longest execution time, ultimately improving the overall performance of the application.
To handle complex scenarios, CodeIgniter's database configuration supports the use of ________ to extend its capabilities.
- drivers
- extensions
- features
- plugins
To handle complex scenarios, CodeIgniter's database configuration supports the use of drivers to extend its capabilities. Drivers allow developers to use different types of databases or customize database functionality as needed.
In CodeIgniter's Query Builder, what method is used to insert a batch of data into a database table?
- batchInsert()
- bulkInsert()
- insertBatch()
- multiInsert()
The method used to insert a batch of data into a database table in CodeIgniter's Query Builder is insertBatch(). This is handy when you need to insert multiple records at once.
