Background on Cultural Centers Cultural Centers in the Knowledge Age The Impact of Digital Presence on the Success of Cultural Centers in Germany Master’s thesis within Economics and Management of Arts and Entertainment. Author: Agata Rukat, Rasah Böhm Tutor: Åke Andersson, Pia Nilsson Jönköping June, 2010 Master’s Thesis in Economics and Management of Entertainment & Arts Title: Cultural Centers in the Knowledge Age. The impact of Digital Pres- ence on the Success of Cultural Centers in Germany. Author: Agata Rukat, Rasah Böhm Tutor: Åke Andersson, Pia Nilsson Date: 2010-06-11 Subject terms: Cultural centers, technological innovations, knowledge age, synergy, cultural infrastructure, web 2,0 Abstract This study investigates the digital presence of cultural centers in three regions of Ger- many taking into account the theoretical framework of the knowledge age. In order to find out if the adaption of online tools has a positive influence on visitor reach, i.e. on the success of the centers, the thesis attempts to gather information on online tool us- age of individual institutions via questionnaires. Taking into consideration the overall context three factors referring to traditional economic concepts namely industry size, institution size and program diversity are proposed as additional success factors. The research results indicate that digital presence, together with the other measured factors, have a positive impact on the success of the centers. Moreover, the cultural infrastruc- ture appears to have a direct positive impact on industry size and, consequently, an in- direct impact on the success of cultural centers.

physical footprint and is vital for its continued presence and growth” (Ailsa Barry, Natural History Museum in Ar, p.12) The statement that internet has revolutionized the world is so well known that it became a cliché. Web services opened a spectrum of possibilities for virtually every industry, in- cluding arts and entertainment. The Net, by enabling information flow without con- straints, has brought new rules to the business world. Vogel (2007) writes that “The inter- net is not only a major new medium for the transmission of information and entertainment-a network of all networks, …, but also by now an integral part of every modern business operation.”(146) There is an existing body of literature concerning the impact of internet on arts and en- tertainment institutions (Byrnes, 2004 ;Anderson, 2007). However, the literature is mostly on media companies, museums and the performing arts. Little research has been done on cultural centers which are an important part of the cultural infrastructure. Therefore, this thesis attempts to investigate how cultural centers are affected by inter- net and, by doing so, it aims to provide background for further research. According to the Enquet commission on cultural infrastructure in Germany, cultural centers offer di- verse cultural programs in order to enhance the regional creative activity. The centers are often nonprofit organizations which, as many other institutions in the cultural sec- tor, struggle with budgetary constraints and insufficient demand. In the Knowledge Age the consumer behavior and expectations have changed. Such factors as location, creativ- ity and knowledge dissemination and technology are crucial to mention while discussing the cultural centers in the context of the „new era‟. Taking into consideration the con- cepts referring to knowledge age and cultural centers, two hypotheses were posed and a model was constructed by the researchers. In order to test the model the data was col- lected from e-mail generated questionnaires sent to 230 cultural centers in Germany. In addition, the stars from Michelin Guide 2010 were gathered for the cities that cultural centers are located in order to measure the attractiveness and density of the cultural in- frastructure. The main focus of this thesis, however, is on the adaption of online tools by the cultural centers and how it impacts their success. 1.1 Purpose The purpose of this study Provide the base for research on cultural centers in the knowledge age Examine the impact of online tools on the success of the cultural ters This study was conducted in order

  • Symptoms-Based Detection of Bot Processes
    Symptoms-Based Detection of Bot Processes Jose Andre Morales1, Erhan Kartaltepe1, Shouhuai Xu1,2, and Ravi Sandhu1 1 Institute for Cyber Security, University of Texas at San Antonio {jose.morales,erhan.kartaltepe,ravi.sandhu}@utsa.edu 2 Department of Computer Science, University of Texas at San Antonio [email protected] Abstract. Botnets have become the most powerful tool for attackers to victimize countless users across cyberspace. Previous work on botnet detection has mainly focused on identifying infected bot computers or IP addresses and not on identifying bot processes on a host machine. This paper aims to fill this gap by presenting a bot process detection technique based on process symptoms such as: TCP connection attempts, DNS ac- tivities, digital signatures, unauthorized process tampering, and process hiding. We partition symptoms into sets which are input into classifiers generating individual detection models which are later appropriately in- tegrated so as to improve the detection accuracy. The integrated ap- proach correctly identified two bot processes and did not produced any false positives and false negatives. Keywords: Botnet detection, bot process, process symptom, behavior- based detection, symptom-based detection. 1 Introduction Botnets are an effective tool in spam distribution, denial of service attacks, illegal content hosting and other malicious acts. By leasing botnets, malware authors have successfully implemented profitable business models. These dynamic struc- tures consist of several infected host machines (bots) running the bot software and responding to the bot master’s instructions. Previous work on detection has mainly focused on the identification of infected bot machines or IP addresses, and not the actual bot process executing on the infected machine.

  • Social Network-Based Botnet Command-And-Control: Emerging Threats and Countermeasures
    Social Network-Based Botnet Command-and-Control: Emerging Threats and Countermeasures Erhan J. Kartaltepe1, Jose Andre Morales1, Shouhuai Xu2, and Ravi Sandhu1 1 Institute for Cyber Security, University of Texas at San Antonio {erhan.kartaltepe,jose.morales,ravi.sandhu}@utsa.edu 2 Department of Computer Science, University of Texas at San Antonio [email protected] Abstract. Botnets have become a major threat in cyberspace. In order to effectively combat botnets, we need to understand a botnet’s Command-and-Control (C&C), which is challenging because C&C strate- gies and methods evolve rapidly. Very recently, botmasters have begun to exploit social network websites (e.g., Twitter.com) as their C&C in- frastructures, which turns out to be quite stealthy because it is hard to distinguish the C&C activities from the normal social networking traffic. In this paper, we study the problem of using social networks as botnet C&C infrastructures. Treating as a starting point the current generation of social network-based botnet C&C, we envision the evolution of such C&C methods and explore social networks-based countermeasures. Keywords: Botnet, command-and-control, social networks, security. 1 Introduction The critical difference between botnets and other malware is that botmasters use a Command-and-Control (C&C) to coordinate large numbers of individ- ual bots (i.e., compromised computers) to launch potentially much more dam- aging attacks. Botmasters also evolve their C&C strategies and methods very rapidly to evade defenders’ countermeasures. Therefore, from a defender’s per- spective, it is always important to understand the trends and practices of bot- net C&C [8,15,19,23,29,11,26].
