Include this module in your Internet Protocol Socket Server and easily protect it from Denial of Service Attacks.
There is a Go module and a NodeJS module.
It offers IPv4, IPv6 and a notification closure (callback).
//set authorization status for an IP //logout ipac.ModifyAuth(&ip_ac, 0, "127.0.0.1") //invalid login credentials ipac.ModifyAuth(&ip_ac, 1, "127.0.0.1") //authorized (valid login credentials) ipac.ModifyAuth(&ip_ac, 2, "127.0.0.1") //notify closure, use to send firewall notifications to admins ip_ac.NotifyClosure = func(info string, ips []string) { // info is a string about the event // ips is a list of ip addresses related to the event }
It works with and without iptables.
