Therefore, a DoS attack typically consists of bombarding the victim’s servers with individual packets that contain spoofed source addresses. 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_dos:ddos_dos_synflood&rev=1775221508&do=diff Protection Against SYN Flood Attack GUIInstruction A SYN flood attack causes excessive resource consumption on the target system, because for every incoming SYN packet the system must allocate certain memory resources or generate a special SYN+ACK response containing a cryptographic cookie, perform session table lookups, etc. — in other words, consume significant CPU resources. 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_dos:ddos_dos_udpflood&rev=1775221508&do=diff Protection Against UDP Flood This type of attack is carried out using fragmented UDP packets. The target platform is forced to spend significant resources reassembling and analyzing these packets. Protection is implemented by dropping protocol types that are not relevant to the protected site. Protocol filter configuration is described in the option
