DescriptionCategories
FNFG-FW-000005 - The FortiGate firewall must use filters that use packet headers and packet attributes, including source and destination IP addresses and ports.
FNFG-FW-000015 - The FortiGate firewall must use organization-defined filtering rules that apply to the monitoring of remote access traffic for the traffic from the VPN access points.
FNFG-FW-000020 - The FortiGate firewall must generate traffic log entries containing information to establish what type of events occurred.
FNFG-FW-000025 - The FortiGate firewall must generate traffic log entries containing information to establish when (date and time) the events occurred.
FNFG-FW-000030 - The FortiGate firewall must generate traffic log entries containing information to establish the network location where the events occurred.
