What is a Firewall?
A firewall is used to keep the internal network segment
secure from intruders.
What does a Firewall do?
A firewall ensures that all packets coming into the
internal network does not consist of malicious contents.
This is done by inspecting each packet and decides,
based on your rules, whether they should be allowed.
It helps to prevent hackers break in and filter email
viruses. To protect trusted networks from invasion,
many firewalls are deployed at either the network level
or on the PC.
Why do we need a Firewall in a business environment?
Every business nowadays relies on Internet to retrieve
the latest information and establish a competitive advantage.
Firewall helps business to protect their intangible
assets, while monitoring Internet usage.
