An alarm is an event that triggers a notification, which is a mechanism to tell a network administrator about a condition in the network. In a proxy definition, an alarm might occur when traffic matches, or does not match, a rule in the proxy. An alarm might also occur when the Actions to take selections are set to an action other than Allow.
For example, the default definition of the FTP-proxy has a rule that denies the download of files whose file types match any of these patterns: .cab, .com, .dll, .exe, and .zip. You can specify that an alarm is generated whenever the XTM device takes the Deny action because of this rule.
For each proxy action, you can define what the XTM device does when an alarm occurs.
AV alarm settings are only available if Gateway AntiVirus applies to the proxy. Gateway AntiVirus is available for the SMTP, POP3, HTTP, FTP, or TCP-UDP proxies. For all other proxies, you can only configure the proxy alarm settings.

If you modified a predefined proxy action, when you save the changes you are prompted to clone (copy) your settings to a new action.
