The CAPTCHA page should be placed behind the DPI (support for hosting CAPTCHA on external resources, e.g., Cloudflare, is planned) and service 10 with a protection profile should also be applied to it. At a minimum, the profile should include the parameters ddos_check_server and ddos_security_key. For simplicity, the same profile used for the protected site can be reused. text/html 2026-04-03T13:05:08+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.vasexperts.com/doku.php?id=dpi:dpi_options:opt_ddos:ssg_ddos:ddos_ddos:ddos_ddos_description&rev=1775221508&do=diff General Description To carry out a DDoS attack, an attacker has at their disposal a large network of remotely controlled computers (BOTNET), so there is no longer a need to hide the IP address of each individual device (of course, a BOTNET can also be used to amplify regular DoS attacks). In this case, the attacker can simply mimic the actions of legitimate site users, but due to the large number of computers involved in the attack (sometimes hundreds of thousands), even such actions will … text/html 2026-04-03T13:05:08+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.vasexperts.com/doku.php?id=dpi:dpi_options:opt_ddos:ssg_ddos:ddos_ddos:ddos_ddos_settings&rev=1775221508&do=diff services service_8 ddos_protection Protection Parameters Configuration GUIGuide Activation of this type of protection triggers when one of the thresholds set in the configuration file /etc/dpi/fastdpi.conf is exceeded: ddos_reqsec_threshold=300 ddos_reqsec_variation=5 where ddos_reqsec_threshold is the number of requests per second arriving at the protected site, usually set to the maximum observed under normal site operation. ddos_reqsec_variation is the allowed deviation in percent fr…
