- PACKET INSPECITION
Anmerkungen:
- As the name implies, the
packet inspection firewalls, they inspect every packet, packets coming
into the network or packets leaving the network.
The firewalls will have a set
of rules by which they inspect these packets. If a packet coming in or
leaving the network triggers a rule, the firewall moves to block that
traffic. Where no rules are triggered, the firewall would allow the
traffic, whether in or outgoing.
- APPLICATION FILTERING
Anmerkungen:
- We also have application filtering firewalls,
these are firewalls that look at what applications are being called on by the
traffic.
Should network traffic be calling on applications that they shouldn’t,
the firewall will prevent such communications. Those communications do not get
to the end server.
