Description: A host-based firewall is a security solution installed on individual devices, such as computers and servers, to monitor and control incoming and outgoing network traffic. Unlike network firewalls, which protect an entire network from a central point, host-based firewalls operate at the level of each device, allowing for more granular management of security policies. These systems can filter traffic based on predefined rules, blocking unauthorized connections and allowing only those that meet specific criteria. Additionally, they may offer extra features such as intrusion detection, event logging, and real-time alerts, making them an essential tool for security information and event management. Implementing a host-based firewall is particularly relevant in environments where greater protection of sensitive data is required, as each device can be a vulnerable entry point. Its ability to segment traffic and apply specific security policies on each host contributes to a more robust defense against cyber threats, making this technology a key component in the cybersecurity strategy of various organizations.
