Therefore, aviation security is increasingly important in order to protect the country and its citizens from such attacks. According to Federal of American Scientists 2007, aviation security is realized through combination of private and public aviation security activities across the globe. These activities are then coordinated to detect, prevent, deter, and defeat threats that…… This researcher rejects the existence of online communities because computer mediated group discussions cannot possibly meet this definition. Weinreich's view is that anyone with even a basic knowledge of sociology understands that information exchange in no way constitutes a community. For a cyber place with an associated computer mediated group to be labeled as a virtual settlement it is necessary for it to meet a minimum set of conditions. These are: 1 a minimum level of interactivity; 2 a variety of communicators; 3 a minimum level of sustained membership; and 4 a virtual common public space where a significant portion of interactive computer mediated groups occur Weinreich, 1997. The notion of interactivity will be shown to be central to virtual settlements. Further, it will be shown that virtual settlements can be defined as a cyber place that is symbolically delineated by topic of interest and within which a significant proportion of interrelated interactive computer…… " Harman, Flite, and ond, 2012 the key to the preservation of confidentiality is "making sure that only authorized individuals have access to that information. The process of controlling access limiting who can see what begins with authorizing users. " Harman, Flite, and ond, 2012 Employers are held accountable under the HIPAA Privacy and Security Rules for their employee's actions. The federal agency that holds responsibility for the development of information security guidelines is the National Institute of Standards and Technology NIST.

Window Contacts: Can be hardwired or wireless. Motion Sensors: It’s the most essential and common form of protection. Passive infrared sensors: Detect motion by sensing a sudden change in heat. Dual Tech motion detectors use two different technologies in the same unit: passive infrared and microwave. These devices are designed to avoid false alarms since both technologies must detect motion before setting off the alarm. Photoelectric Sensors: These sensors project a beam of light across a hall or doorway to detect motion and are triggered when a person passing through interrupts the beam. Glass Break Detectors: Usually mounted near windows to detect the specific high frequency sound of glass being shattered. They are usually installed on a wall opposite or adjacent to the protected glass and are effective within about 15′ to 25′. Smoke and Heat Detectors: Detect smoke and heat. Chapter II:Our Home Alarm SystemOur Home Alarm System:Our project’s main concern was to build a Home Alarm System using a PIC microcontroller. We started off our project by coding the Keypad, then LCD and the final touch was the sensor.
