Ensure Intrusion Prevention(IPS) policy is configured on active firewall rules

高等級 2人工審核sophos

說明

Network attacks can be prevented using IPS rules. The firewall matches signatures with traffic patterns and takes the action specified in the rule. IPS signatures identify threats and specify a recommended action to take when the firewall encounters matching traffic. Signatures are specific to applications, services, or platforms. The firewall includes predefined signatures and you can also create custom signatures. Reviewed in the Sophos Firewall web admin console (SFOS has no plain-text configuration export to audit offline).
