    Vulnerability and Protection of Critical Infrastructures

    Full text link
    Critical infrastructure networks are a key ingredient of modern society. We discuss a general method to spot the critical components of a critical infrastructure network, i.e. the nodes and the links fundamental to the perfect functioning of the network. Such nodes, and not the most connected ones, are the targets to protect from terrorist attacks. The method, used as an improvement analysis, can also help to better shape a planned expansion of the network.Comment: 4 pages, 1 figure, 3 table

    The Drug Problem and Organized Crime, Illicit Financial Flows, Corruption and Terrorism

    An estimated quarter of a billion people, or around 5 per cent of the global adult population, used drugs at least once in 2015. Even more worrisome is the fact that about 29.5 million of those drug users, or 0.6 per cent of the global adult population, suffer from drug use disorders. This means that their drug use is harmful to the point that they may experience drug dependence and require treatment.The magnitude of the harm caused by drug use is underlined by the estimated 28 million years of "healthy" life (disability-adjusted life years (DALYs)) lost worldwide in 2015 as a result of premature death and disability caused by drug use.Of those years lost, 17 million were attributable solely to drug use disorders across all drug types. DALYs attributable to morbidity and mortality resulting from all causes of drug use have increased overall in the past decade.Yet, with fewer than one in six persons with drug use disorders provided with treatment each year, the availability of and access to science-based services for the treatment of drug use disorders and related conditions remain limited

    Federalism as an effective antidote to terrorism

    Many governments as well as terrorist experts see the use of military and police forces as the only way to effectively counter terrorism. The most effective negative sanctions are considered to be military strikes, aggressive actions (including kidnapping and killing) against individuals known or suspected of being terrorists, or against persons supporting and harboring terrorists. Overt and covert military and paramilitary action is also thought advisable to pre-empt and prevent actions by terrorist groups, as well as against states suspected of hosting or tolerating terrorists. This paper argues that decentralization constitutes a powerful antidote as it strongly reduces the incentives for terrorists to attack and because the expected damage suffered is much smaller than in a centralized society. It moreover strengthens society, as economic, political and social decentralization (or polycentricity) is an essential element of a free and vigorous society. This in turn makes a society less vulnerable to terrorist attacks. Indeed, terrorism has no chance of success against a society that actively guards its fundamental liberal institutions, of which decentralized decision-making forms an essential part

    Effective Counterterrorism: What Have We Learned so Far?

    The fight against terrorism, in particular of Islamist nature, has become a focus area of foreign and security policies in Western countries and around the world. This substantial effort is however only to a limited extent matched by adequate evaluations as to its actual success. This paper offers an overview of the counterterrorism effectiveness literature in terms of main areas of interest, conceptualisation and operationalisation difficulties as well as methodological considerations regarding the types of methods used, validity and reliability evaluations. It discusses the different understandings of causality and proposes a working definition of counterterrorism effectiveness. We find that a main focus of the literature lies on the impact component of effectiveness, often in the sense of a reduction of terrorist attacks in general or a reduction of certain methods of terrorism such as suicide attacks. Our model article "What Happened to Suicide Bombings in Israel? Insights from a Terror Stock Model" by Kaplan et al. (2005) illustrates the above-mentioned issues and reflects the mainstream approach in this field. The article uses econometric methods to determine the impact-effectiveness of counter-terrorism and reflects the problematique associated with attempts to infer a causal relationship between counterterrorism policies and the occurrence of terrorism.Counterterrorism, effectiveness, causality, quantitative and qualitative research methods

    A Broad Evaluation of the Tor English Content Ecosystem

    Full text link
    Tor is among most well-known dark net in the world. It has noble uses, including as a platform for free speech and information dissemination under the guise of true anonymity, but may be culturally better known as a conduit for criminal activity and as a platform to market illicit goods and data. Past studies on the content of Tor support this notion, but were carried out by targeting popular domains likely to contain illicit content. A survey of past studies may thus not yield a complete evaluation of the content and use of Tor. This work addresses this gap by presenting a broad evaluation of the content of the English Tor ecosystem. We perform a comprehensive crawl of the Tor dark web and, through topic and network analysis, characterize the types of information and services hosted across a broad swath of Tor domains and their hyperlink relational structure. We recover nine domain types defined by the information or service they host and, among other findings, unveil how some types of domains intentionally silo themselves from the rest of Tor. We also present measurements that (regrettably) suggest how marketplaces of illegal drugs and services do emerge as the dominant type of Tor domain. Our study is the product of crawling over 1 million pages from 20,000 Tor seed addresses, yielding a collection of over 150,000 Tor pages. We make a dataset of the intend to make the domain structure publicly available as a dataset at https://github.com/wsu-wacs/TorEnglishContent.Comment: 11 page

    The Economics of Terrorism and Counter-Terrorism: A Survey (Part II)

    Get PDF
    This survey provides an in-depth analysis of existing research on the economic analysis of terrorism and counter-terrorist measures. First the existing evidence on the causes of terrorism is analyzed, then we consider the evidence of the consequences of terrorism and we demonstrate why it is important to regarding of the issue of counter-terrorism policy. Moreover the survey presents the existing knowledge on the interrelation between the economy and the issue of security and it incorporates analysis the level of knowledge about the causal chains between security and the economy. Also it focuses on perspective and methodologies from the discipline of economics but also refers to research from related disciplines (sociology, political science). It also assembles the knowledge on the impact of terrorism on the economy as reflected in macro-economic variables and its impact on specific sectors. Furthermore it assesses how potential an actual terrorist event determine consumer and producer behaviour, public policy, as well as terrorist responses to these policies. Finally a European perspective on the terrorism security annexes is discussed and here we analyze the causes of terrorism in Europe.risk, insecurity, survey, terrorism, counter-terrorism, security economics
