Deep Packet Inspection Definition
What Is Deep Packet Inspection?
Deep packet inspection (DPI) is a kind of data processing.
It inspects the data being sent over a data pipe in detail.
According to different inspection results, DPI takes different actions like alerting, blocking, re-routing, or logging.
It is also called packet sniffing.
Deep Packet Inspection vs Stateful Packet Inspection
There are multiple headers for IP packets.
data pipe equipment only needs to use the first of those headers for normal operation.
Its capabilities have evolved to overcome the limitations of traditional firewalls that rely on stateful packet inspection.
This post tells you the different types of firewalls and you might know which one to choose.
Besides, you’re free to use the firewall alternative to protect the PC.
So, many firewall vendors adopt it.
Thus, many users choose to skip the inspection.
In response to that, many administrators usually choose to turn off their firewalls.
