How to Reduce the Risk of Data Breach Related to Blacklisted IP Address?

Question:

Your company has suffered a data breach to an IP address subsequently found to appear on several threat reputation blacklists. What configuration change can you make to reduce the risk of further events of this type?

Answer:

To reduce the risk of further data breaches related to an IP address appearing on several threat reputation blacklists, you can implement a firewall, use Intrusion Detection/Prevention Systems (IDS/IPS), and regularly update and patch your systems.

Explanation:

Implement a firewall: By configuring a firewall, you can filter incoming and outgoing traffic, blocking any suspicious or malicious connections to your network.

Use Intrusion Detection/Prevention Systems (IDS/IPS): These systems can detect and prevent unauthorized access attempts or suspicious activities within your network.

Regularly update and patch your systems: Keep your systems and software up to date to fix any vulnerabilities that could be exploited.

By making these configuration changes, you can strengthen the security of your network and reduce the risk of data breaches linked to blacklisted IP addresses.
