What is Cybersecurity?
Cybersecurity comprises a set of technologies and practices that ensure the availability, integrity, and confidentiality of information percolating through digital systems, networks, devices, and sensors. This rough definition of cybersecurity is already insufficient because digital technologies are themselves rapidly evolving, reshaping human experience and understanding, and generating complexity and effects that extend beyond what humans can reasonably know or manage.
Our lives are now shaped at all levels by digital technologies: from fundamental critical infrastructure to prosaic crib-side monitors and coffee makers. The use and abuse of algorithms shape what we know to be true about the distribution of power, resources, and even the coherence of our social fabric.
These dynamics make cybersecurity one of the most professionally important and intellectually interesting domains—a true, twenty-first century master problem.
In the not-too-distant future, we expect the evolving and expanding concept of cybersecurity to morph simply, but significantly, into “security.” Cybersecurity will be synonymous with the broader concept of security and will be ubiquitous.
Technology and Humans
At the turn of the century, scholars and practitioners considered cybersecurity to be a difficult but bounded technical problem. Cybersecurity was an effort to secure computers and networks against malicious activities aimed at stealing data or money or at compromising national security.
Cyberattacks evolved from computers and networks to social engineering techniques and from there to hacks of personal identities and manipulation of objects and systems in the physical world. Today, the practice of cybersecurity includes technologies, processes, and policies; cybersecurity experts are called upon to protect users in many contexts beyond the screen. For cybersecurity professionals, human behaviors are as important as technical safeguards.
Cybersecurity at Berkeley
We designed the Master of Information and Cybersecurity (MICS) program from the ground up to meet this emerging set of cybersecurity challenges. We believe the next generation of cybersecurity professionals will need technical capabilities and a deep contextual understanding of the ways in which digital insecurities shape societies, organizations, and individuals.
Cybersecurity professionals can make the greatest impact at the intersection of these domains. The UC Berkeley School of Information also sits intellectually at this intersection. We are teachers, researchers, and practitioners who bring together the ethical, social, political, economic, legal, military, and technical components of cybersecurity, so we can equip graduates to become leaders in the field, whether they wish to lead in the private, public, or philanthropic sector.
There is no silver bullet for addressing cybersecurity challenges. No static set of capabilities will ensure the career success of a cybersecurity professional. Our program is designed to develop students’ capacity to master the concepts, skills, toolsets, and insights needed to fuel a long and dynamic cybersecurity career.
