Why is it so important to use the rule of blacklist firewall?

The rule of a blacklist firewall is crucial because it allows organizations to explicitly deny access to known malicious IP addresses, domains, or protocols, thereby reducing the risk of cyberattacks. By filtering out harmful traffic, a blacklist firewall helps protect sensitive data and resources from unauthorized access. Additionally, it can enhance overall network performance by minimizing unwanted traffic. This proactive approach is vital for maintaining a secure and efficient network environment.
