Secure Logging of Retained Data for an Anonymity Service [chapter]

Stefan Köpsell, Petr Švenda
2010 IFIP Advances in Information and Communication Technology  
A practical implementation of the proposed scheme was performed for the AN.ON anonymity service, but the scheme can be used for other services affected by data retention legislation.  ...  We have analyzed the newly arising risks associated with the process of accessing and storage of the retained data and propose a secure logging system, which utilizes cryptographic smart cards, trusted  ...  The authors would like to thank all anonymous reviewers, Jan Camenisch and Jakub Švenda for their valuable comments and Microsoft Research for the generous support which allowed the presentation of this  ...

Outsourcing Security Analysis with Anonymized Logs

Jianqing Zhang, Nikita Borisov, William Yurcik
2006 2006 Securecomm and Workshops  
In this paper we analyze the logs used for security analysis with the concern of privacy and propose the constraints on anonymization of security monitor logs.  ...  As security monitoring grows both more complicated and more sophisticated, there is an increased demand for outsourcing these tasks to Managed Security Service Providers (MSSPs).  ...  The use of anonymization as privacy-enhancing technique for facilitating the sharing of data for security monitoring is a growing area of study.  ...

Data Retention and Anonymity Services [chapter]

Stefan Berthold, Rainer Böhme, Stefan Köpsell
2009 IFIP Advances in Information and Communication Technology  
The reference architecture for our study is the anonymity service AN.ON, from which we also collect empirical data.  ...  The recently introduced legislation on data retention to aid prosecuting cyber-related crime in Europe also affects the achievable security of systems for anonymous communication on the Internet.  ...  An urgent question is which data exactly has to be logged by anonymity services such as AN.ON in order to comply with the data retention law.  ...

Big Data Privacy and Management

Sanjay Thimmarayappa, Megha V
2014 International Journal of Computer Applications  
Along with the security concerns, data management also becomes an important factor to be considered.  ...  Therefore, traditional security mechanisms tailored to secure small-scale, static data are insufficient.  ...  Since most of this data is innocent, we can preserve anonymity by making sure that none of this data is retained.  ...

Sharing Computer Network Logs for Security and Privacy: A Motivation for New Methodologies of Anonymization [article]

Adam J. Slagell, William Yurcik
2004 arXiv   pre-print
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.  ...  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.  ...  The amount of time a name server retains cached data is controlled by the time-to-live (TTL) field for the data.  ...

Sharing network logs for computer forensics: a new tool for the anonymization of netflow records

A.J. Slagell, Yifan Li, K. Luo
2005 Workshop of the 1st International Conference on Security and Privacy for Emerging Areas in Communication Networks, 2005.  
Ideally, they would support multiple levels of anonymization that trade-off between security-of the anonymization scheme-and utility-the amount of useful information retained in anonymized logs.  ...  Anonymization solutions should support multiple levels of anonymization to trade-off between security (of the anonymization scheme) and utility (of the anonymized log data).  ...

Towards an Efficient Log Data Protection in Software Systems through Data Minimization and Anonymization

A. Omar Portillo-Dominguez, Vanessa Ayala-Rivera
2019 2019 7th International Conference in Software Engineering Research and Innovation (CONISOFT)  
In this paper, we propose an automatic approach (SafeLog) to filter out information and anonymize log streams to safeguard the confidentiality of sensitive data and prevent its exposure and misuse from  ...  IT infrastructures of companies generate large amounts of log data every day.  ...  Most of the existing work has evaluated the utility of anonymized network traces for detecting security threats [36] , [37] .  ...

Data Handling in the Smart Grid: Do We Know Enough? [chapter]

Richard Chow, Alvaro Cardenas, Emiliano De Cristofaro
2013 IFIP Advances in Information and Communication Technology  
Data privacy in the smart grid is an important requirement for consumers.  ...  Central to the data privacy issue is the handling of energyusage data, in particular, data retention, aggregation and anonymization.  ...  Some U.S. carriers store call activity logs for days, some for months, some even retain call and text message content.  ...

It also allows for the exchange of log files between different providers for cross-analysis or its submission to a single analysis center (as an outsourced service) in an opt-in basis.  ...  To this end, in the context of this paper, we assert that audit trails in VoIP can be a rich source of information toward flushing out DoS incidents and evaluating the security level of a given system.  ...  Anonymization of log files The privacy and security requirements of the proposed scheme are strongly related 215 to the robustness of the anonymization process conducted on the log files.  ...

Pseudonymizing Unix Log Files [chapter]

Ulrich Flegel
2002 Lecture Notes in Computer Science  
Our tools are based on an approach to pseudonymizing Unix log files while balancing user requirements for anonymity and the service provider's requirements for accountability.  ...  By pseudonymizing identifying data in log files the association between the data and the real persons is hidden.  ...  Most of all Sven Bursch, Kai Grundmann, Stefan Magerstedt and Dennis Real deserve credit for their tireless work on the code as well as the measurements of the tools.  ...

FLAIM: A Multi-level Anonymization Framework for Computer and Network Logs [article]

Adam Slagell, Kiran Lakkaraju, Katherine Luo
2006 arXiv   pre-print
FLAIM (Framework for Log Anonymization and Information Management) addresses two important needs not well addressed by current log anonymizers.  ...  First, it is extremely modular and not tied to the specific log being anonymized.  ...  Consequently, in step with the growth of the computer security field, there has been an increase in the need for sound methods of sharing log data.  ...
