Discuss what a firewall is and its role in a company's overall security scheme.
What will be an ideal response?
A firewall is hardware or software that can be configured to block unauthorized access to a
network. Firewall is often viewed as a catch-all term to represent any device that can block
attackers or viruses.
Firewalls cannot protect against employees who send proprietary information outside an organization through a network connection or copy confidential data to a disk. A strong security policy and access controls on sensitive information are needed to protect against such incidents. A firewall also cannot protect connections that do not go through it, such as remote dial-up connections. These connections require a virtual private network (VPN) for protection.
The term firewall does not necessarily refer to a single router, computer, VPN gateway, or
software program. Any network firewall is a combination of software and hardware components. A firewall can consist of all devices positioned on the network perimeter, so the
term firewall perimeter might be more descriptive.
