Cyber security has attracted a tremendous amount of attention lately due to recent cyber-attacks that have been publicized in the news. Internet of Things (IoT) connected devices have given users the amazing ability to connect devices in distant, isolated areas saving time and money, while minimizing risk. However, this connectivity comes at a cost. Remote devices can be susceptible to cyber-attacks such as hacks, viruses and spyware invasions that can go undetected until it is too late. Remote devices can also be even more prone to physical unauthorized access or damage because security focus tends to be elsewhere.
While cyber security is not to be downplayed, physical security should not be overlooked and is equally concerning. Physical attacks could jeopardize critical units like Supervisory Control and Data Acquisition (SCADA) systems, Intelligent Electronic Devices (IEDs), and Smart Cities and Transportation management solutions. This could lead to widespread, costly and hazardous damage to city services, water systems and even more.
Awareness is critical when trying to determine a balanced security solution for IoT applications. Below are some key questions to be considered as you assess threats and determine the best solutions.
? What type of information must be collected? The data typically falls into two categories - alarm data and log data.
? What type of sensors will be needed?
? Will the sensors use radio, Wi-Fi or cellular for connection, or a combination of two or more?
? What power source is available? Battery, hardwire, or other?
? Will managers and security personnel have insight into what actions to take?
