Fighting E-Mail Abuses: The EMPE Approach [chapter]

Massimiliano Pala, Antonio Lioy
2006 Lecture Notes in Computer Science  
In this paper we present the E-Mail Policy Enforcer system (EMPE) which provides a method to cryptographically bind the identity of the original sender of an e-mail to the message body by combining digital  ...  Electronic mail is one of the most used and abused service in today communication. While many efforts have been made to fight e-mail abuses, no effective solution has yet been developed.  ...  For every word in these emails, it calculates a spam probability based on the proportion of spam occurrences.  ...

A Trust Overlay Architecture and Protocol for Enhanced Protection against Spam

Adding digital forensic readiness to electronic communication using a security monitoring tool

F. R. Van Staden, H. S. Venter
2011 2011 Information Security for South Africa  
Tracing the origin of spam by using the information contained in SMTP headers is not possible because SMTP is a clear text protocol and can easily be intercepted and modified.  ...  Unsolicited electronic communication, also known as spam, is just one such example of abuse of email.  ...  Any opinion, findings and conclusions or recommendations expressed in this material are those of the author(s) and therefore the NRF does not accept any liability in regard thereto.  ...

A Trust Based System for Enhanced Spam Filtering

Jimmy McGibney, Dmitri Botvich
2008 Journal of Software  
Trust by one mail server in another is influenced by direct experience as well as recommendations issued by collaborating mail servers.  ...  The effectiveness of current anti-spam systems is limited by the ability of spammers to adapt to filtering techniques and the lack of incentive for mail servers to filter outgoing spam.  ...  ACKNOWLEDGMENT This work was supported by the European Commission (OPAALS FP6 project) and by Science Foundation Ireland (Foundations of Autonomics project).  ...

Tightening the net: A review of current and next generation spam filtering tools

James Carpinter, Ray Hunt
2006 Computers & security  
This paper provides an overview of current and potential future spam filtering approaches. We examine the problems spam introduces, what spam is and how we can measure it.  ...  While a range of different techniques have and continue to be evaluated in academic research, heuristic and Bayesian filtering dominate commercial filtering systems; therefore, a case study of these techniques  ...  Many proposals to change the way in which we send email have been put forward, including the required authentication of all senders, a per email charge and a method of encapsulating policy within the email  ...

An effective defense against email spam laundering

Mengjun Xie, Heng Yin, Haining Wang
2006 Proceedings of the 13th ACM conference on Computer and communications security - CCS '06  
Laundering email spam through open-proxies or compromised PCs is a widely-used trick to conceal real spam sources and reduce spamming cost in underground email spam industry.  ...  In this paper, we reveal one salient characteristic of proxy-based spamming activities, namely packet symmetry, by analyzing protocol semantics and timing causality.  ...  To counter the soaring growth of spam volume, many ISPs have adopted the policy of blocking port 25 (SMTP port), in which outbound email from a subscriber must be relayed by the ISP-designated email server  ...
