monitoring security system enterprise wide security. Should they be different, should it be enterprise wide ignoring the special needs of any particular site. Keep in mind that employees travel from one site to another often and need to access computing resources from any site to get their work done. The classic enterprise network for most organizations used to be hub and spoke arrangement, but demand for higher bandwidth led to the decrease in the cost of leased lines and the emergence of new technologies, such Virtual Private Networks that could mesh offices together. Enterprise ide Security on the Internet, March 2002 This created another problem, however, as the larger the enterprise, the greater the need for security, yet the larger the network, the more diverse the informative needs of the employees. The first solution that was deployed in the early…… However, this still relatively young application of internet technology does come with a wide array of security concerns that highlight the ethical and legal responsibilities facing these handlers of sensitive information.

Also, many systems use motion sensors that compute the proximity of a room’s walls by producing infrared beams and measuring the time required for them to bounce back; if a beam comes back sooner than expected, it likely bounced off of a person and the sensor registers motion. When the alarm system is installed, each sensor is registered with the control panel either through wires or wirelessly. The control panel also interfaces with keypads and other input devices used by the home owner to control the system. The control center keeps track of the status of the sensors and reports activity through LCD displays and other output devices. Moreover, when activity takes places, such as the opening of a window, the sensors report the activity to the control center and the center registers that a disturbance has occurred. In managed alarm systems, the control panel also checks the sensors to verify that they are still operational; if a sensor fails to reply, the center alerts the home owner of an out of order sensor.

We started off by setting the first four ports of PORTB as the inputs and the latter four ports as the outputs.
