The Internet has made large amounts of info available to computer users, which has become essential rather than an advantage for many. Connecting a private network to the Internet can expose critical or confidential data to malicious attacks from anywhere. Firewalls can protect both individual computers (software) and corporate networks (hardware and software) from hostile intrusion from the Internet. Either way, it must have at least two network interfaces, one for the network it is intended to protect, and one for the network it is exposed to. A firewall sits at the junction point or gateway between the two networks, usually a private network and a public network such as the Internet, and it examines all traffic routed between the two networks to see if it meets certain criteria. If it does, it is routed between the networks, otherwise it is stopped. A firewall filters both inbound and outbound traffic.
Firewalls only address the issues of data integrity, confidentiality and authentication of data that is behind the firewall. Any data that transits outside the firewall is subject to factors out of the control of the firewall.
Luckily, most, if not all computers, have firewall software.
With computer monitoring, you have the power to record what someone does and when they do it. Some monitoring software will record email, keystrokes, chats, instant messages, keystrokes, websites, screenshots, usernames, passwords, and more. Virtually All computer and Internet activities that occur on a monitored computer will be recorded. The benefits are unlimited. Home users can use this software as a backup for sensitive data, monitoring their suspicious children, increasing employee productivity, and much more.
