programmed into the device so that the router will always assign it that IP

regardless of the other IP addresses in the network. This is important when

intruders. Network security is vitally important for businesses as they often

have sensitive data stored on their networks. There are several utilities that

the installer should be aware of when installing network infrastructure.

The first one is firewalls. As in a building, firewalls are intended to

keep unwanted activity from passing onto your network. This includes

viruses, and other types of malware that could otherwise cause harm or

steal information. Firewalls work by closing down all network activity except

for what the user specifies as legitimate. This may include email accounts,

internet access, and automatic software updates. Often certain types of

firewall on a given computer. In this situation, an exception must be

created, or the firewall should be turned off temporarily.

Anti-virus software is another form of network security. Many anti-

virus manufactures also include other applications such as anti-spyware,

firewalls etc. Anti-virus works by actively scanning the computer for threats.

It can usually be setup to run a periodic system scan as well as all
