Cybersecurity experts scan the internet and face security events that influence users, institutions, and governments. An information security analyst regularly examines sources to stay up to date on security events in her/his domain of expertise. This may lead to a heavy workload for the information analysts if they do not have proper tools for security event investigation. For example, an information analyst may want to stay aware of cybersecurity events, such as a DDoS (Distributed Denial of Service) attack on a government agency website. The earlier they detect and understand the threats, the longer time remaining to alleviate the obstacle and to investigate the event. Therefore, information security analysts need to establish and keep situational awareness active about the security events and their likely effects. However, due to the large volume of information flow, it may be difficult for security analysts and researchers to detect and analyze security events timely. There have been attempts to solve this problem both from an academic perspective and engineering purposes. A recent challenge in this domain is that the internet community use different languages to share information. For instance, information about security events in Turkey is mostly shared on the internet in Turkish. The present thesis investigates the automatic detection of security incidents in Turkish by processing Twitter and news media. It proposes an automatic, Turkish specific software system that can detect cybersecurity events in real time.

Challenges of countering cyber terrorism in the hybrid war contexts Tanrısever, Oktay Fırat (null; 2019-10-15) This conference paper seeks to explore the characteristics of cyber terrorism and challenges of countering cyber terrorism in the hybrid war contexts. This conference paper also intends to highlight the difficulties of coping with the terrorist uses of the cyber space and social media when the perpetrators of cyber terrorist acts remain anonymous and the parties of hybrid warfare adhere to the principle of deniability constantly The conference paper puts forward the argument that the concept of cyber terror...
Increasing trustworthiness of security critical applications using trusted computing Uzunay, Yusuf; Baykal, Nazife; Bıçakcı, Kemal; Department of Information Systems (2014) In this thesis work, we aim to increase the trustworthiness of security critical applications by utilizing trusted computing technologies. We focus on two case applications; authentication proxy systems and e-voting systems. Our first case application is authentication proxy systems which store users’ sensitive credentials and submit them to the servers of the service providers on their behalf. To increase the trustworthiness of authentication proxy systems, we propose Trust-in-the-Middle a trusted platform...
Detection of malicious web pages Süren, Emre; Özkan Yıldırım, Sevgi; Department of Information Systems (2014) Cyber-attacks have been shaking the virtual world and malicious web pages have become a major weapon for Internet crimes. They host a number of malicious contents; such as spam, phishing, and drive-by download. Drive-by download technique exploits the victim’s machine and downloads a malware without any notice or consent. After infection, victim’s private data is stolen or encrypted and even worse the compromised machine is instrumented to mount further attacks. To this end, researchers have focused on prot...
Reflections on Turkish Personal Data Protection Law and Genetic Data in Focus Group Discussions Özkan, Özlem; Şahinol, Melike; Aydınoğlu, Arsev Umur; Aydın Son, Yeşim (2022-12-01) Since the 1970s and more rigorously since the 1990s, many countries have regulated data protection and privacy laws in order to ensure the safety and privacy of personal data. First, a comparison is made of different acts regarding genetic information that are in force in the EU, the USA, and China. In Turkey, changes were adopted only recently following intense debates. This study aims to explore the experts’ opinions on the regulations of the health information systems, data security, privacy, and confide...
