The new “compound increment percentage” Server! version: 4.0.16+ Server! v4.0.16 introduced a new (yet very important) improvement to the Protectorâ„¢ technology: the compound increment percentage.

Before this update, the Protectorâ„¢ would put an attacker’s IP address in the blacklist for a predetermined amount of time, and remove it from the blacklist once said time had past. But attackers often try to connect to the server to attempt further attacks even when they are already blacklisted.

The updated Protectorâ„¢, instead, features a significant difference: if an attacker tries to connect to the server while already blacklisted, the attacker’s IP address blacklist expiration will be prolonged by an amount of time that is calculated using the above “increment percentage” compound to the “number of identified attack attempts” while such IP was already blacklisted. Logn story short: if an attacker keeps attacking, its IP address may very well never get out of the blacklist even when the blacklist is set to ban attackers IPs only temporarily. Continue reading
