2.5: Security and Privacy
Understanding the Trade-offs: Balancing Security and Privacy With Other Values Other Information:
Understanding the Trade-offs: Balancing Security and Privacy With Other Values -- Designing a system or a network that satisfies
a single design goal -- security -- is still a grand challenge in computer science research. Yet, in reality, many systems
and networks like the Internet that are used by real people have to satisfy not just one goal but an array of them. For example,
they need to be usable; they should give users the information and personal privacy they expect; they should be open enough
so that users can connect with others at a distance and obtain information that is available on other systems and networks.
At the same time, the systems need to provide the level of security required by the end users. In many cases, however, it
is not possible to satisfy all competing goals. Where we are now -- we are just beginning to understand the implications of
such conflicts. If it is not possible to design a system that is simultaneously secure, privacy-preserving, usable, and open,
what are the potential trade-offs among those attributes? We need to better understand these trade-offs and expand the space
of possible solutions. Research needs -- research is necessary to investigate how we can more effectively comprehend, model,
and optimize an array of conflicting design goals. In addition, new tools are needed to enable IT managers and end users both
to monitor and act to mitigate security risks.
