A device or software application that can disconnect a suspicious network connection.

A Firewall is a device or software application that can disconnect a suspicious network connection. It monitors incoming and outgoing network traffic and decides whether to allow or block specific traffic based on a defined set of security rules.

Here are the steps a Firewall takes to disconnect a suspicious network connection:

1. Monitoring: The Firewall continuously monitors the data packets being sent and received through the network.

2. Rule Checking: Each data packet is checked against a set of rules defined in the Firewall. These rules are designed to identify suspicious or harmful data packets.

3. Blocking: If a data packet is found to be suspicious or does not comply with the rules, the Firewall blocks it from entering the network.

4. Reporting: The Firewall then reports the blocked connection to the network administrator.

5. Updating: The Firewall rules are regularly updated to protect against new threats.

So, a Firewall acts as a barrier between a trusted internal network and untrusted external networks, such as the Internet, and disconnects any suspicious network connection.
