"Revolutionary technological changes-including shared and dispersed cloud computing capabilities; mobile computing devices and smart phones; increased use of social media; and interdependencies of computing systems-are exploding across the electronic communications landscape and are being adopted at a rapid pace in both public and private sectors. In this new environment, continuous access to data has become central to mission performance across all operational lines; however, just as technological advancement can yield benefits (e.g., enhanced access, efficiencies, and cost savings), mission reliance on data also elevates risks and consequences of data security. These advancements have introduced thousands of applications, threats, and vulnerabilities into communications networks, which are increasingly hidden from traditional network security devices. Given organizations' reliance on these advancements to conduct even basic business functions, cyber threats that previously only affected a small fraction of business activities are beginning to impact all sectors and business functions."
