B. In this case, you need a search warrant to confiscate equipment without giving the suspect

confidential, a constant signal of a specific frequency, a randomly variable signal such as the white noise heard between radio stations or television stations, or even a jam signal that causes interception equipment to fail. White noise is most effective when created around the perimeter of an area so that it is broadcast outward to protect the internal area where emanations may be needed for normal operations. The final type of TEMPEST countermeasure, a control zone, is simply the implementation of either a Faraday cage or white noise generation in an environment where a specific area is protected while the rest is not. A control zone can be a room, a floor, or an entire building. Con- trol zones are those areas where emanation signals are supported and used by necessary equip- ment, such as wireless networking, mobile phones, radios, and televisions. Outside of the control zones, emanation interception is blocked or prevented through the use of various TEM- PEST countermeasures. Environment and Life Safety An important aspect of physical access control and maintaining the security of a facility is pro- tecting the basic elements of the environment and protecting human life. In all circumstances and under all conditions, the most important aspect of security is protecting people. Preventing harm to people is the most important goal of all security solutions. Personnel Safety Part of maintaining safety for personnel is maintaining the basic environment of a facility. For short periods of time, people can survive without water, food, air conditioning, and power. But in some cases, the loss of these elements can have disastrous results or they can be symptoms of more immediate and dangerous problems. Flooding, fires, release of toxic materials, and natu- ral disasters all threaten human life as well as the stability of a facility. Physical security proce- dures should focus on protecting human life and then on restoring the safety of the environment and restoring the utilities necessary for the IT infrastructure to function. People should always be your top priority. Only after personnel are safe can you consider addressing business continuity issues. Many organizations are adopting Occupant Emergency Plans OEPs to guide and assist with sustaining personnel safety in the event of a disaster. The OEP provides guidance on how to minimize threats to life, prevent injury, and protect property from damage in the event of a destructive physical event. The OEP does not address IT issues or business continuity, just personnel and general property. The BCP and DRP address IT and business continuity and recovery issues. Power and Electricity Power supplied by electric companies is not always consistent and clean. Most electronic equip- ment demands clean power to function properly. Equipment damage due to power fluctuations
