Convergence of IP-Based Networks
In the early days of the Internet, the only way to connect to the Web was by using a modem in conjunction with a dial-up connection. The modems, which stand for modulator-demodulator, were devices that converted analog signals into digital signals. Early modems operated at 1200 bps or bit/s per second to 2400 bps. Data transfer was slow and often unreliable.
Today the Internet and the means to access the Internet has changed radically from the days of the modem. We now use lightning fast networks that include broadband, T1, satellite and digital wireless connections. The modernization of network technology has enabled the invention of cell phones, and other devices that allow users to access the Web and other networks from almost anywhere in the world and beyond.
The advancement in network technology has led to its share of security risks. Attacks against networks, user’s personal information and corporate information have changed how the world deals with network security. The idea of Network Security is no longer an afterthought but the driving force in all network designs. IT managers are now concerned with securing data, ensuring only authorized end users have access to resources, and protecting the integrity of hardware, software and devices.
A converged network has many of the same risks and susceptibility to threats as you might find if you were dealing with two separate networks. Denial of Service attacks against banks data storage servers could cause a lot of harm and potentially cause the loss of millions of dollars, Identification theft or loss of confidence for the organization. Converged networks place more information and resources in line with each other than would be found in having separate networks for each network needed to operate a company. This just means IT managers have to place all safeguards in one place.
Wireless or mobile technology has added another
