1. NETWORK SECURITY

   • NETWORK DEVICES
     • FIREWALLS
       • PACKET INSPECITION
         • 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
         • 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.
