Review the three types of data interception: direct observations, interception of data transmissions, and electromagnetic interception.

• Direct observations require that a person be close enough to the information to breach confidentiality.

• Interception of data transmissions can occur from anywhere, as they are not restricted to a location with the exception to tapping into a LAN, eavesdropping on a secure network, or wiretapping.

• Electromagnetic interception is another type of interception, although it is unlikely to occur. Though possible, it is difficult, impractical, and expensive to carry out.
