This is becoming a considerable disturbance to telecommunications. Spam is also closely related to other kinds of cyber crime as it possibly contains malicious software or is pursuing some kind of fraudulent aim, such as phishing. Besides technical and organizational measures, many countries have introduced anti-spam legislation. However, today's world-wide legislative coverage of spam is heterogeneous, and its effectiveness is controversially discussed. This article describes important parameters by which anti-spam legislation can vary and gives an overview and analysis of world-wide anti-spam legislation, including the European Directive 2002/58/EC, the U.S. CANSPAM Act of 2003, and international cooperation, such as the London Action Plan. The article then proceeds to discuss the effectiveness of current laws, and it identifies problems resulting from the fact that an international phenomenon is being addressed by national legislation.

Up to now, by deploying complementary anti-spam measures, we have been reasonably able to withstand spam e-mails and use the Internet for regular communication. However, if we are to avert the danger of losing the Internet e-mail service in its capacity as a valuable, free and worldwide medium of open communication, anti-spam activities should be performed more systematically than is currently the case regarding the mainly heuristic, anti-spam measures in place. A formal framework, within which the existing delivery routes that a spam e-mail may take, and anti-spam measures and their effectiveness can be investigated, will perhaps encourage a shift in methodology and pave the way for new, holistic anti-spam measures. This paper presents a model of the Internet e-mail infrastructure as a directed graph and a deterministic finite automaton and draws on automata theory to formally derive the spam delivery routes. The most important anti-spam measures are then described. Methods controlling only specific delivery routes are evaluated in terms of how effectively they cover the modeled e-mail infrastructure; methods operating independently of any particular routes receive a more general assessment."}],"ddc":["000"],"user_id":"61579","language":[{"iso":"eng"}],"date_updated":"2022-01-06T07:02:22Z","oa":"1","department":[{"_id":"277"}],"title":"Do anti-spam measures effectively cover the e-mail communication network?

Even worse, the impacts of these messages are far from being simply an annoyance, as they also involve economic damage. This manuscript examines the resource ?email addresses?, which is vital for any potential bulk mailer and spammer. Both a methodology and a honeypot conceptualization for implementing an empirical analysis of the usage of email addresses placed on the Internet are proposed here. Their objective is to assess, on a quantitative basis, the extent of the current harassment and its development over time. This ?framework? is intended to be extensible to measuring the effectiveness of address-obscuring techniques. The implementation of a pilot honeypot is described, which led to key findings, some of them being: (1) Web placements attract more than two-thirds (70\\%) of all honeypot spam emails, followed by newsgroup placements (28.6\\%) and newsletter subscriptions (1.4\\%), (2) the proportions of spam relating to the email addresses? top-level domain can be statistically assumed to be uniformly distributed, (3) More than 43\\% of addresses on the web have been abused, whereas about 27\\% was the case for addresses on newsgroups and only about 4\\% was the case for addresses used for a newsletter subscription, (4) Regarding the development of email addresses? attractiveness for spammers over time, the service ?web sites? features a negative linear relationship, whereas the service ?Usenet? hows a negative exponential relationship. (5) Only 1.54\\% of the spam emails showed an interrelation between the topic of the spam email and that of the location where the recipient?s address was placed, so that spammers are assumed to send their emails in a ?context insensitive? manner. The results of the empirical analysis motivate the need for the protection of email addresses through obscuration. We analyze this need by formulating requirements for address obscuring techniques and we reveal to which extent today?s most relevant approaches fulfill these requirements."}],"extern":"1","user_id":"61579","ddc":["000"],"file":[{"file_size":3026200,"creator":"hsiemes","file_id":"6326","content_type":"application/pdf","date_updated":"2018-12-18T13:27:01Z","relation":"main_file","date_created":"2018-12-18T13:27:01Z","file_name":"The Impact that Placing Email Addresses on the Internet has on the Receipt of Spam - An Empirical Analysis - Journal version.pdf","access_level":"open_access"}],"file_date_updated":"2018-12-18T13:27:01Z","keyword":["Address-obfuscating techniques","email","empirical analysis","honeypot","security by design","security by obscurity","spam"],"publication":"Computers & Security","publisher":"Elsevier","author":[{"full_name":"Schryen, Guido","first_name":"Guido","id":"72850","last_name":"Schryen"}],"date_created":"2018-11-14T14:53:12Z","has_accepted_license":"1","status":"public","volume":2},{"language":[{"iso":"eng"}],"type":"conference","citation":{"short":"G.

So far we have been reasonably able to resist spam e-mails and use the Internet for regular communication by deploying complementary anti-spam approaches. However, if we are to avert the danger of losing the Internet email service as a valuable, free, and worldwide medium of open communication, anti-spam activities should be performed more systematically than is done in current, mainly heuristic, anti-spam approaches. A formal framework within which the modes of spam delivery, anti-spam approaches, and their effectiveness can be investigated, may encourage a shift in methodology and pave the way for new, holistic anti-spam approaches. This paper presents a model of the Internet e-mail infrastructure as a directed graph and a deterministic finite automaton, and draws on automata theory to formally derive the modes of spam delivery possible. Finally the effectiveness of anti-spam approaches in terms of coverage of spamming modes is assessed.","lang":"eng"}],"extern":"1"},{"page":"22-25","year":"2005","type":"journal_article","citation":{"mla":"Schryen, Guido. “A Honeypot for the Exploration of Spammers’ Behaviour.” IATAC IAnewsletter, vol. 8, no. 3, United States Department of Defense, 2005, pp. 22–25.","bibtex":"@article{Schryen_2005, title={A honeypot for the exploration of spammers’ behaviour}, volume={8}, number={3}, journal={IATAC IAnewsletter}, publisher={United States Department of Defense}, author={Schryen, Guido}, year={2005}, pages={22–25} }","chicago":"Schryen, Guido. “A Honeypot for the Exploration of Spammers’ Behaviour.” IATAC IAnewsletter 8, no. 3 (2005): 22–25.","ama":"Schryen G.

The article starts with a brief presentation of advantages and disadvantages of Internet ballots and presents application fields and pilot schemes. Then, technological security aspects are derived due to democratic basic principles. Especially the applied voting procedures are critical in security terms. Hence, the most relevant cryptographic protocols are presented and their drawbacks and shortcomings are identified. However, this article does not propose a new voting protocol. Beyond fixing cryptographic procedures for ballots, more elements are to be specified, e.g. responsibilities and rights of involved authorities or security precautions regarding hardware and software. For this reason, a structural security framework for electronic voting systems is presented which can be used for their composition and analysis.","lang":"eng"}],"date_created":"2018-11-20T13:02:25Z","status":"public","has_accepted_license":"1","department":[{"_id":"277"}],"publication":"37th Annual Hawaii International Conference on System Sciences","file_date_updated":"2018-12-18T13:32:44Z","author":[{"full_name":"Schryen, Guido","first_name":"Guido","id":"72850","last_name":"Schryen"}],"file":[{"content_type":"application/pdf","date_updated":"2018-12-18T13:32:44Z","relation":"main_file","file_size":385671,"file_id":"6332","creator":"hsiemes","access_level":"open_access","file_name":"Conference version - Security Aspects of Internet Voting.pdf","date_created":"2018-12-18T13:32:44Z"}]},{"title":"Effektivität von Lösungsansätzen zur Bekämpfung von Spam","department":[{"_id":"277"}],"date_updated":"2022-01-06T07:02:24Z","oa":"1","language":[{"iso":"eng"}],"extern":"1","abstract":[{"lang":"eng","text":"Spam als unerwünschte Massen-E-Mail hat die Grenze von der Belästigung zur ökonomischen Relevanz längst überschritten.
