Reports of cyber criminals, "hacktivists" and nation-states accessing sensitive information and disrupting services in both the public and private domains have risen steadily, heightening concerns over the adequacy of cybersecurity measures. Cybersecurity related concerns range from spearfishing attempts and spam, to malware, to illegal or illicit activity on the dark net. More and more cases of successful cyber-attacks are being reported. Financial information, medical records, any and all personal data maintained on computer systems by individuals or by organizations large and small are vulnerable. Mobile, wireless technology presents new opportunities for cyber-attacks. As more devices communicate with one another, from security systems to thermostats, the "Internet of Things" presents a growing target. Social media sites and advertisements also present opportunities for cybersecurity breaches.
