Infomation is the flow of information from one entity to another. This can be done without a computer or network. It can occur on the internet or intranet, in an email, on CD-ROM or in file sharing systems.
Computers are a great way to get infomation. They are fast and inexpensive and have a large storage capacity. Network attached storage (NAS) gives access to a user’s files from a network location, without the use of a computer. A CD-ROM contains data that is saved to a hard disk. File sharing systems give access to applications on a computer or network, without requiring the user to store all downloaded data on his computer.
Software such as email, instant messaging, and word processing has become essential components of a business’s infrastructure. Employees can access and send messages to each other in real time. The ability to retrieve data from a remote location allows a company to save money on software licensing fees. Some companies now use network scanning tools to discover weak spots in their networks. When a software program is installed, all computers on a network are scanned for “back doors” in the software that allow access to the outside world.
Network infomation can also occur when a network is brought down for repairs. All data is lost. It is important to have backup systems in place before this happens. Most insurance companies require that you have back up data when you experience a complete network failure. There are times when the best defense against a complete network failure is prevention by installing effective firewalls and software.
Intrusion detection systems to detect intruders and shut them down before they can do much damage. Network intrusion detection can include software that triggers a password alarm when anyone accesses a secured computer system. Other types of infomation are done by checking the traffic that is passing through an Ethernet wire. Traffic is monitored to see if certain types of data are being exchanged. If data is being exchanged that is not secure, then the Ethernet port is disabled. It is very common for businesses to be without an Ethernet port because it takes a lot of training and money for employees to learn how to work with the new technology.
Companies should always look at their infomation practices closely. There are many ways for an infomation attack to occur. When a company is not careful, they may find themselves in a situation where they have spent a lot of money and resources to secure but still cannot protect themselves. If an infomation attack occurs, there are many things that can be done to regain control of the network.
