1.1.2 LAN Network Protection

In most cases, firewalls are deployed to protect the local network (LAN) from attacks
originating from the WAN (such as the Internet). However, security outbreaks are possible on
the LAN via other means (such as file sharing with removable storage devices). You can use
the ZyWALL to provide network security on the LAN.
In the following example, computers in the Sales and Research departments are protected from
each other by the ZyWALLs on the LAN.
