Description: A host firewall is a security system that is installed directly on a host machine to monitor and control incoming and outgoing network traffic. Its primary function is to protect the operating system and applications running on the machine from unauthorized access and malicious attacks. Unlike network firewalls, which protect an entire network, host firewalls focus on the security of a single device. These firewalls can be configured to allow or block connections based on specific rules, such as IP addresses, ports, and protocols. Additionally, they often include advanced features like intrusion detection, event logging, and real-time alerts. In various computing environments, host firewalls are essential for ensuring the security of individual devices, providing an additional layer of defense in a shared resource environment. Host firewalls are a crucial tool in any organization’s security strategy, helping to mitigate risks and protect sensitive data.
