SPI application inspection provides the same automatic protections offered by application proxy firewalls.

Question

Quizplus · Accepted Answer

SPI (Stateful Packet Inspection) primarily examines data packets and their headers to determine the state of a connection and make decisions based on the state and context of the packets. Application proxy firewalls, on the other hand, act as an intermediary between end users and the services they access, inspecting and filtering at a higher level of the OSI model, which allows for more granular control and inspection of the data, including the content of the messages. This means application proxy firewalls can offer more comprehensive protections, such as deep content inspection and application-specific protocols understanding, which SPI does not inherently provide.
