The Cybersecurity and Privacy field has been one of the most critical parts of our lives and modern society at large. With the evolution of computing, communications, lightweight handheld devices and smart things/devices in the Internet of Things (IoT), we have networked services with anywhere-at-anytime connectivity for different applications such as smart transportation, production and manufacturing, logistics, energy, healthcare, utility, recreation, social and many other domains [1, 2, 3]. Furthermore, advancements in computing, communications and control engineering help cyber systems to monitor and control physical systems/operations in a real time manner for emerging cyber physical systems (CPS) [1, 4, 5, 6]. However, the massive number of connections in IoT/CPS brings new security vulnerabilities and privacy challenges [1, 2, 5, 7, 8, 9, 10]. Thus, cybersecurity and privacy are critical to such connected systems to offer secure and trustworthy networked services [2, 5, 7]. When the Internet was created, cybersecurity was not part of the initial requirements, since the fundamental Internet protocols did not include measures against users attacking one another using communications and computing devices [11]. However, lately, hundreds of billions of dollars are spent on cybersecurity every year to combat cyber-attacks. People's lives are relying on smart sensors and connected systems, such as water infrastructure [8], smart energy grid [4, 12, 13], smart transportation [1, 9, 14, 15], e-health [7] and wireless systems [16], among others, more new security and privacy challenges are emerging. In some applications, security and privacy are contradicting to each other, such as in vehicular communications; when the identity of vehicles (which is linked with driver/owner/renter) is used, the privacy of the driver/owner/renter could be easily compromised, and when anonymous identity is used for vehicular communications to provide privacy, achieving authentication and trustworthy secure communication becomes challenging. Thus, we need to consider a tradeoff while designing such techniques for privacy-aware security. Furthermore, many emerging applications need a real-time response to control the operations; to address these issues related to latency, cyber defense solutions should be light-weight and usable for such systems. Cyber-attacks can be launched from anywhere through connected systems and the highly interconnected systems apart from the obvious advantages bring major issues too as a higher number of easily accessed malware targets. Meanwhile, the jurisdiction authorities need to obtain legitimate access to the systems/data under the laws ruling the specific region. Thus, it is very important to protect networked systems by considering all aspects of cyber-attacks. Furthermore, networked systems can be used by enemies for cyber-warfare, state-sponsored intelligence activities and criminal activities. If, or when, World War III happens, it is predicted to be in the cyber-space, or it will be leveraging cyber-attacks to destroy or disable the nation's critical infrastructure. For example, instead of destroying a country's energy grid systems by physical bombs to disable the enemy's power systems, coordinated cyber-attacks will be launched to disable the smart energy grid [12, 13]. Similarly, instead of closing the main sources of water supply of the country/city/military-facility, the enemy could contaminate the water with deadly chemicals though connected water infrastructure [8]. Likewise, smart vehicles can be used to create traffic jams and scaled traffic accidents. Thus, the country'ssmart critical infrastructure could be easily used against the country by enemies through cyber-attacks. National defense agencies such as law enforcement, national security, private or public agencies must, thus, work together to deter, protect, prevent and respond to a multitude of cyber-attacks targeted to a variety of the nation's critical networked systems and infrastructure.
