• What is SPI?
  • Stateful packet inspection (or dynamic packet filtering) is a technology that monitors active connections and checks whether incoming data packets correspond to these connections. It then decides whether to grant or deny permission for them to pass the firewall.
  • the SPI firewall checks whether these packets are legitimate and correspond to an already established connection. It discards packets that do not relate to a known connection, thus minimizing the possibility of a breach.
