Be Aware of Electromagnetic Radiation

In 1985, the concerns of the paranoid among the security community were confirmed. Wim van Eck released a paper confirming that a well-resourced attacker can read the output of a cathode-ray tube (CRT) computer monitor by measuring the electromagnetic radiation (EMR) produced by the device. This isn't particularly easy to do, but it is by no means impossible. Wim's paper can be found here

Vocabulary Exercise Completion Mqf

A fiber optic is a glass or plastic conductor that transmits information using light. A fiber-optic cable is one or more optical fibers enclosed together in a sheath or jacket. Because it is made of glass, fiber-optic cable is not affected by electromagnetic interference or radio frequency interference. Fiber-optic cable can reach distances of several miles or kilometers before the signal needs to be regenerated. However, fiber-optic cabling is usually more expensive to use than copper cabling. The connectors are more costly and harder to assemble. And all signals have to be converted to light pulses to enter the cable and back into electrical signals when they leave it.

How Bandwidth Is Achieved from RF Signals

Figure 1-1 shows the entire electromagnetic spectrum. Notice that the frequency ranges used in CB radio, FM radio, and TV broadcasts are only a fraction of the entire spectrum. Most of the spectrum is governed by folks like the FCC. This means that you cannot use the same frequencies that FM radio uses in your wireless networks. As Figure 1-1 illustrates, the electromagnetic spectrum spans from Extremely Low Frequency (ELF) at 3 to 30 Hz to Extremely High Frequency (EHF) at 30 GHz to 300 GHz. The data you send is not done so in either of these ranges. In fact, the data you send using WLANs is either in the 900-MHz, 2.4-GHz, or 5-GHz frequency ranges. This places you in the Ultra High Frequency (UHF) or Super High Frequency (SHF) ranges. Again, this is just a fraction of the available spectrum, but remember that the FCC controls it. You are locked into the frequency ranges you can use.

FDDI Transmission Media

FDDI uses optical fiber as the primary transmission medium, but it also can run over copper cabling. As mentioned earlier, FDDI over copper is referred to as Copper-Distributed Data Interface (CDDI). Optical fiber has several advantages over copper media. In particular, security, reliability, and pe rformance all are enhanced with optical fiber media because fiber does not emit electrical signals. A physical medium that does emit electrical signals (copper) can be tapped and th erefore wou Id permit unaut horized access to the data that is transiting the medium. In addition, fiber is immune to electrical interference from radio frequency interference (RFI) and electromagnetic interference (EMI). Fiber historically has supported much higher bandwidth (throughput potential) than copper, although recent technological advances have made copper capable of transmitting at 100 Mbps.

OSI Layer 1 for Pointto Point WANs

As a brief review, remember that Ethernet uses a twisted pair of wires to transmit and another twisted pair to receive, to reduce electromagnetic interference. You typically use straight-through Ethernet cables between end user devices and the switches. For the trunk links between the switches, you use crossover cables because each switch transmits on the same pair, so the crossover cable connects one device's transmit pair to the other device's receive pair. The lower part of the figure reminds you of the basic idea behind a crossover cable.

Wireless Local Area Networks

Although wireless networking began to penetrate the market in the 1990s, the technology has actually been around since the 1800s. A musician and astronomer, Sir William Her-schel (1738 to 1822) made a discovery that infrared light existed and was beyond the visibility of the human eye. The discovery of infrared light led the way to the electromagnetic wave theory, which was explored in-depth by a man named James Maxwell (1831 to 1879). Much of his discoveries related to electromagnetism were based on research done by Michael Faraday (1791 to 1867) and Andre-Marie Ampere (1775 to 1836), who were researchers that came before him. Heinrich Hertz (1857 to 1894) built on the discoveries of Maxwell by proving that electromagnetic waves travel at the speed of light and that electricity can be carried on these waves.

Other Equipment

Fiber-optic cabling is all but immune to line problems such as electromagnetic interference (EMI) because light is used and not electricity. In secured environments, fiber-optic transport is preferred because it is difficult to tap and it is simple to detect if a tap is present. Also, there is no signal resonance as with copper wiring, so signal hijacking becomes exponentially more difficult.

Circuit Switching

ISDN is deployed between the service provider's CO and the customer's premises. The local loop, deployed over a combination of copper and possibly optical cable, must observe the same stipulations of any digital technology. In other words, the ISDN carrier facilities are equally as susceptible to problems such as cross talk and attenuation as any analog circuit. As far as interference goes, fiber-optic trunks do not need to worry about electromagnetic interference (EMI). Optical trunks can also transport information for much greater distances before the need for signal regeneration. Service providers tend to deploy high bandwidth, fiber trunks to integrated digital loop carrier (IDLC) systems and then provide copper service from there to the customer's premises.

History of DSL

In the 1980s, Bellcore developed high-data-rate DSL (HDSL) technology. HDSL was developed to enhance the capabilities of T1 technology by replacing alternate mark inversion (AMI) encoding with 2 binary 1 quaternary (2B1Q) encoding. HDSL reduces the need for repeaters, and it causes less electromagnetic interference (EMI) in cable bundles. In the 1990s, technology vendors began to see an explosion in the use of the Internet. This Internet revolution increased the demand for pure data, as opposed to voice and data, access to the Internet. The increase of high-bandwidth Internet services, such as video-on-demand, audio-on-demand, e-shopping, e-learning, and telecommuting, has resulted in the demand for higher bandwidth data connections. Studies showed that the majority of the traffic that was sourced from the Internet was destined for the end user (downstream), and that only a small percentage of the traffic was actually sourced by the user (upstream).

Wireless Propagation

When electron streams change direction rapidly within a wire or antenna, the electrostatic and magnetic fields around the wire or antenna change at the same rapid rate. These rapidly changing fields are called electromagnetic waves. The electromagnetic waves do not simply stay near the antenna they travel away at nearly the speed of light 186,000 miles per second (300,000,000 meters per second). The changing electron flow within the antenna has been transformed into electromagnetic (wireless) waves traveling away from the antenna.
