SPI Stateful Packet Inspection (SPI) inspects, and if required blocks packets at
the application layer. SPI also maintains TCP and UDP session information,
including timeouts and the number of active sessions, and provides the
ability to detect and prevent certain types of network attacks such as DoS
attacks.
Denial of Service (DoS) attacks are aimed at devices and networks with a
connection to the Internet. The goal is not to steal information, but to
disable a device or network so users no longer have access to network
resources.
