Symmetric encryption uses the same key to encrypt and decrypt data, making it more efficient for bulk data encryption. Asymmetric encryption uses a public key and a private key, making it more secure but less efficient for bulk data encryption. Hashing algorithms convert data into a fixed-size, unique code (hash) that cannot be reversed, making it ideal for verifying the integrity of data.
• 11. What is a vulnerability assessment, and why is it important?
  Answer: A vulnerability assessment is a process of identifying and evaluating security vulnerabilities in a system or network. It is important to conduct regular vulnerability assessments to proactively identify weaknesses in your environment and address them before they can be exploited by attackers. This helps to prevent data breaches and other security incidents.
• 12. How do you secure a wireless network?
  Answer: To secure a wireless network, I would first disable broadcast of the network's SSID to prevent unauthorized users from seeing and connecting to the network. I would also enable WPA2 encryption and set a strong password to protect the network. Additionally, I would configure MAC address filtering to restrict access to specific devices, and regularly update the firmware on network devices to patch any vulnerabilities.
• 13. Can you explain the concept of least privilege and how it enhances security?
  Answer: Least privilege is a principle that limits user privileges to only those necessary for them to perform their job functions. This helps to prevent unauthorized access to sensitive data and systems, reducing the chances of a data breach or cyberattack. It also helps to mitigate the impact of security incidents by limiting the damage that can be caused by compromised accounts.
• 14. How do you handle improper error handling in an application?
  Answer: To handle improper error handling, I would first analyze the source code for the application to identify the root cause of the issue. I would then implement proper error handling techniques, such as validating inputs and restricting error messages that reveal sensitive information. I would also conduct penetration testing to ensure the issue has been resolved.
