10. What is the risk of exposing sensitive information in configuration files, even if backup files are secure?
- No risk, as sensitive information is always protected.
- Attackers may gain insights into the application's settings, potentially leading to security breaches.
- Exposing sensitive information enhances server security.
- Sensitive information in configuration files has no impact on web security.
Even if backup files are secure, exposing sensitive information in configuration files may allow attackers to gain insights into the application's settings, potentially leading to security breaches.
11. What is the potential impact if an attacker gains access to database credentials stored in a configuration file?
- No impact, as database credentials are always encrypted.
- Attackers can use the credentials to access and manipulate the database, potentially leading to data breaches or data manipulation.
- Database credentials stored in configuration files are automatically secure.
- The impact is limited to the web server's performance.
If an attacker gains access to database credentials stored in a configuration file, they can use the credentials to access and manipulate the database, potentially leading to data breaches or data manipulation.
12. In addition to database credentials, what other sensitive information might be stored in configuration files?
- Only information relevant to server administrators.
- Encryption keys, API keys, and other secrets crucial to the application's security.
- Configuration files do not store sensitive information.
- Information about website aesthetics.
In addition to database credentials, configuration files might store encryption keys, API keys, and other secrets crucial to the application's security.
13. Why might developers include comments in configuration files, and what risk does this pose?
- Comments in configuration files have no impact.
- Developers include comments for documentation purposes, but this might unintentionally expose sensitive information.
- Including comments is a security best practice.
- Comments in configuration files only affect developers.
Developers might include comments in configuration files for documentation purposes, but this might unintentionally expose sensitive information, posing a risk.
14. How can attackers leverage information from backup files to conduct a "directory traversal" attack?
- Directory traversal attacks are unrelated to backup files.
- By manipulating file paths within the backup files to access unauthorized directories and files.
- Attackers can only conduct directory traversal attacks on live web applications.
- Directory traversal attacks are limited to server administrators.
Attackers can leverage information from backup files to conduct a "directory traversal" attack by manipulating file paths within the backup files to access unauthorized directories and files.
15. Why is it crucial to encrypt or secure backup files even if they are not included in the web application's deployment?
- Encryption is unnecessary for secure backup files.
- Secure backup files enhance website aesthetics.
- In case attackers gain unauthorized access to the server or backup storage, encrypted backup files provide an additional layer of protection.
- Secure backup files automatically protect sensitive information.
Even if backup files are not included in the web application's deployment, encrypting or securing them is crucial. In case attackers gain unauthorized access to the server or backup storage, encrypted backup files provide an additional layer of protection.

18. Why is it advisable for developers to use environment variables or secure vaults for sensitive information instead of storing it directly in configuration files?
- Storing sensitive information directly in configuration files is a security best practice.
- Environment variables and secure vaults provide better performance than configuration files.
- Storing sensitive information directly in configuration files enhances security.
- Environment variables and secure vaults offer better security by centralizing and controlling access to sensitive information.
It is advisable for developers to use environment variables or secure vaults for sensitive information instead of storing it directly in configuration files because environment variables and secure vaults offer better security by centralizing and controlling access to sensitive information.
