Ideally revisited on a rolling basis, effective preparation develops response resources such as organizational and logistics plans, supply caches, medical facilities, and civil services which will be needed during a response phase. As preparation infrastructure improves, society can address broader ranges of risks, resulting in a better prepared society. In that sense, regardless of whether society is well prepared, the Preparation phase sets the stage for the Response…

The account might be high jacked, or there might be data breaches, or it is possible that it might be an inside job.

are not very secure. They often store the network key information in plain text without encryption or password protection. Simple AT commands can often be used to retrieve this information if the device is physically accessible. All Zigbee devices in the network have access to the encryption keys so that packets can be encoded and decoded. As a result, an attacker only needs to find the weak link in the network and exploit it to gain access to the key information. Zigbee devices are often spread…
