(IPv4|IPv6) default deny policy is not configured in Linux firewall -- Trigger???
What is the trigger for the following rules?
IPv4 default deny policy is not configured in Linux firewall
IPv6 default deny policy is not configured in Linux firewall
The systems it's flagging are Ubuntu 20.04 with UFW installed and active, with the default inbound policy set to deny.
The description is pretty vague and doesn't provide a current vs expected state.
Description:
"It is impossible to configure every possible action for all connections while configuring firewall rules. Therefore, it is advisable to set default policy to deny all connections to IPv4 and specify the connections to be allowed."
