Literature Overview - Privacy in Online Social Networks
In recent years, Online Social Networks (OSNs) have become an important\ud
part of daily life for many. Users build explicit networks to represent their\ud
social relationships, either existing or new. Users also often upload and share a plethora of information related to their personal lives. The potential privacy risks of such behavior are often underestimated or ignored. For example, users often disclose personal information to a larger audience than intended. Users may even post information about others without their consent. A lack of experience and awareness in users, as well as proper tools and design of the OSNs, perpetuate the situation. This paper aims to provide insight into such privacy issues and looks at OSNs, their associated privacy risks, and existing research into solutions. The final goal is to help identify the research directions for the Kindred Spirits project
Sharing Computer Network Logs for Security and Privacy: A Motivation for New Methodologies of Anonymization
Logs are one of the most fundamental resources to any security professional.
It is widely recognized by the government and industry that it is both
beneficial and desirable to share logs for the purpose of security research.
However, the sharing is not happening or not to the degree or magnitude that is
desired. Organizations are reluctant to share logs because of the risk of
exposing sensitive information to potential attackers. We believe this
reluctance remains high because current anonymization techniques are weak and
one-size-fits-all--or better put, one size tries to fit all. We must develop
standards and make anonymization available at varying levels, striking a
balance between privacy and utility. Organizations have different needs and
trust other organizations to different degrees. They must be able to map
multiple anonymization levels with defined risks to the trust levels they share
with (would-be) receivers. It is not until there are industry standards for
multiple levels of anonymization that we will be able to move forward and
achieve the goal of widespread sharing of logs for security researchers.Comment: 17 pages, 1 figur
