How does antivirus scanning work on a Firebox?

Antivirus scanning on a Firebox operates by examining files that are transmitted over the network for signatures of known malware. This process involves checking files against a database of malware signatures, which are unique patterns or characteristics that identify specific malware. When a file matches a signature in the database, the antivirus can take action, such as blocking or quarantining the file, thereby preventing potential infections. This method is effective at detecting and stopping known threats before they can compromise systems or data.

In contrast to other options, this scanning method focuses on the direct analysis of files as they move through the network, ensuring that harmful software does not enter the environment. Other options, while they may relate to security in broader terms, do not accurately describe the mechanism by which antivirus protection specifically functions within the Firebox framework.
