What should be done when operating behind a firewall to enhance security?

• A. Whitelist IPs
• B. Disable all connections
• C. Use default ports
• D. Increase timeout settings

Answer: (A)

Whitelisting IP addresses is a best practice for enhancing security when operating behind a firewall. By allowing only specific, trusted IP addresses to connect to your system, you effectively create a barrier against unauthorized access. This approach limits exposure to potential threats since only predetermined connections are permitted, minimizing the risk of attacks from unknown or malicious sources. Utilizing this strategy means you have greater control over who can interact with your network, ensuring that external access is only granted to devices or users that you have explicitly authorized. Whitelisting is especially important in environments where sensitive data is stored or processed, as it helps maintain the integrity and confidentiality of that information. This choice directly contributes to a layered security approach, complementing other measures that might be in place, such as encryption and intrusion detection systems. Therefore, implementing IP whitelisting is an effective way to bolster your security while maintaining necessary access for legitimate users.
