Spam mitigation using spatio-temporal reputations from blacklist history

Andrew G. West, Adam J. Aviv, Jian Chang, Insup Lee
2010 Proceedings of the 26th Annual Computer Security Applications Conference on - ACSAC '10  
IP blacklists are a spam filtering tool employed by a large number of email providers.  ...  However, spammers can vary which hosts send spam (often in intelligent ways), and as a result, some percentage of spamming IPs are not actively listed on any blacklist.  ...  The authors would like to thank Wenke Lee and David Dagon, both of Georgia Tech, for their initial guidance on this project.  ...

2013 Lecture Notes in Computer Science  
Finally, experiments and their results are presented to show the performance of the proposed composition approach.  ...  Given an IaaS provider IP , the reputation of its IaaS − −−−− → q rt (IP ) = [q CP U rt (IP ),q Net rt (IP ), q Sto rt (IP ) ] is a three-attribute vector, where q CP U rt (IP ) (q Net rt (IP ), q Sto  ...  rt (IP )) is the reputation for processing a computation (data transfer, storage) request.  ...

FHSD: An Improved IP Spoof Detection Method for Web DDoS Attacks

S. N. Shiaeles, M. Papadaki
2014 Computer journal  
FHSD uses fuzzy empirical rules and fuzzy largest of maximum operator to identify offensive IPs and mitigate offending traffic.  ...  The most common target is web services, the downtime of which could lead to significant monetary costs and loss of reputation.  ...  The use of information such as the subnet and geographical location of the IP helps to shrink a little the area of IPs. But for better results, a good database with IP hops should be maintained.  ...

Developing Security Reputation Metrics for Hosting Providers [article]

Arman Noroozian, Maciej Korczyński, Samaneh TajalizadehKhoob, Michel van Eeten
2016 arXiv   pre-print
Existing metrics typically count instances of abuse and sometimes normalize these counts by taking into account the advertised address space of the provider.  ...  Research into cybercrime often points to concentrations of abuse at certain hosting providers.  ...  This overlap constitutes 9% of the MLAT feed. In comparison, 124 2LD, IP pairs represents 17% of the MELD feed.  ...

Secured Creditor Control in Bankruptcy: Costs and Conflict

Andrea Polo
2012 Social Science Research Network  
The residual claimants here are the unsecured creditors about whom the IPs have no reputational concerns. Unsecured creditors are neither the appointers of the IPs nor repeat players in bankruptcy.  ...  Having access to a database of insolvency in the UK and, in particular, to data on the secured and unsecured debt recovery rates we are in a unique position to empirically assess this trade-off and analyse  ...

Toward a standard benchmark for computer security research

Tudor Dumitras, Darren Shou
2011 Proceedings of the First Workshop on Building Analysis Datasets and Gathering Experience Returns for Security - BADGERS '11  
WINE includes representative field data, collected worldwide from 240,000 sensors, for new empirical studies, and it will enable the validation of research on all the phases in the lifecycle of security  ...  In this paper, we review the unique characteristics of the WINE data, we discuss why rigorous benchmarking will provide fresh insights on the security arms race and we propose a research agenda for this  ...  These data sets enable two research directions: (i) empirical studies for understanding each phase in the lifecycle of cyberattacks, and (ii) quantitative evaluations and comparisons of attack prevention  ...

A Voice Spam Filter to Clean Subscribers' Mailbox [chapter]

Seyed Amir Iranmanesh, Hemant Sengar, Haining Wang
2013 Lecture Notes of the Institute for Computer Sciences, Social Informatics and Telecommunications Engineering  
In particular, based on Dynamic Time Warping (DTW), we develop a speaker independent speech recognition system to make content comparison of speech messages.  ...  Using our system, the voice messages left on the media server by callers are matched against a set of spam filtering rules involving the study of call behavioral pattern and the analysis of message content  ...  Hence, it is empirically found that the similarity score using DTW is tightly related to the size of speech words.  ...
