Terveydenhuolto ja kyberuhkat
2019
Kyberturvallisuusstrategian vision mukaan Suomen tulee kyetä suojaamaan elintärkeät toimintonsa kyberuhkaa vastaan kaikissa tilanteissa. Terveydenhuolto on yksi elintärkeistä toiminnoista. Terveystoimiala on kyberhyökkäysten top-5-listalla ensimmäisenä. Hyökkäysten keskeisin motivaatio on potilastietojen arvo pimeillä markkinoilla. Vuonna 2015 varastettiin yli satamiljoonaa potilastietoa, jotka sisältävät rikollisille arvokkaita tietoja, kuten luottokorttinumeroita, työnantajatietoja ja sairaushistoriatietoja. Tässä artikkelissa kuvataan terveydenhuoltoon liittyviä kyberuhkia, kyberhaavoittuvuuksia ja toteutuneita kyberhyökkäyksiä kybermaailman eri ulottuvuudet kattaen. Tarkastelussa käytet…
Protecting the besieged cyber fortress : Russia’s response to cyber threats
2019
The Information Security Doctrine of the Russian Federation (RF) defines the threat to information security as a complex of actions and factors that represent a danger to Russia in the information space. These threats can be information-psychological (i.e., when the adversary tries to influence a person’s mind) or information-technical (i.e., when the object of influence is the information infrastructure). The information infrastructure of the RF is a combination of information systems, websites, and communication networks located in the territory of the RF, or those used as part of international treaties signed by the RF. A cyber threat is an illegal penetration or threat of penetration by…

A Study of a Social Behavior inside the Online Black Markets
2010
Illegal activities in cyberspace involving software vulnerabilities have resulted in tangible damage on computer-based environments. Lately, online black market sites for trading stolen goods, credentials, malware and exploit kits have been intensively examined. The market players are identifiably a group of loosely tied individuals but posses shared interests. However, their social behavior has only been discussed in a limited manner. This paper examines the arrangement of the market insiders’ social behavior that enables such forums to continue or discontinue their operation and become a meaningful threat to security. The results reveal that particular formal and informal regulations and …
E-health systems in digital environments
2019
As we live in the digital world, people can be provided with more effective treatment methods that allow them to live longer in their home and to live there better. People can be provided with better home care and preventive health care. People can easily carry portable sensors and intelligent devices in their bodies and wrists that relay their vital information to hospital systems in real time, from which healthcare staff can track human vitality even in real time. Although the digital world offers good opportunities to improve healthcare systems and make disease analyses more effective, we must look deeper about that issue. Devices and systems may not work well together. Almost every manu…
Low-cost active cyber defence
2014
The authors of this paper investigated relatively simple active strategies against selected popular cyber threat vectors. When cyber attacks are analysed for their severity and occurrence, many incidents are usually classifi ed as minor, e.g. spam or phishing. We are interested in the various types of low-end cyber incidents (as opposed to high-end state- sponsored incidents and advanced persistent threats) for two reasons: • being the least complicated incidents, we expect to fi nd simple active response The authors analysed the proposed strategies from the security economics point of view to determine why and how these strategies might be effective. We also discuss the legal aspects of th…
Leveraging the benefits of big data with fast data for effective and efficient cybersecurity analytics systems : A robust optimisation approach
2020
In recent times, major cybersecurity breaches and cyber fraud within the public and private sectors are making international headlines. Majority of organisations are facing cybersecurity adversity and advanced threats. On the one hand, we have asynchronous cybersecurity practices, many standards and frameworks to consider while on the other hand, we have to deal and secure our organisations against cyber-criminals, organised hacktivists, insider threats, hackers and nation-states with malafide intentions. The Center for Cyber Safety and Education's Global Information Security Workforce Study (GISWS) confirms that globally we are not only loosing but also backpedalling against threats and ri…
Strategic cyber threat intelligence : Building the situational picture with emerging technologies
2020
In 2019, e-criminals adopted new tactics to demand enormous ransoms from large organizations by using ransomware, a phenomenon known as “big game hunting.” Big game hunting is an excellent example of a sophisticated and coordinated modern cyber-attack that has a significant impact on the target. Cyber threat intelligence (CTI) increases the possibilities to detect and prevent cyber-attacks and gives defenders more time to act. CTI is a combination of incident response and traditional intelligence. Intelligence modifies raw data into information for decision-making and action. CTI consists of strategic, operational, or tactical intelligence on cyber threats. Security event monitoring, event-…
AI-based quantum-safe cybersecurity automation and orchestration for edge intelligence in future networks
2023
The AIQUSEC (AI-based quantum secure cyber security automation and orchestration in the edge intelligence of future networks) brings measurable advances to the cyber security of access and edge networks and their services, as well as Operational Service Technologies (OT). The research aims for significant cybersecurity scalability, efficiency, and effectiveness of operations through improved and enhanced device and sensor securities, security assurance, quantum security, and Artificial Intelligence (AI) based automation solutions. The new application scenarios of near future, the multiple stakeholders within each scenario, and the higher data volumes raise the need for novel cybersecurity s…
A Novel Model for Cybersecurity Economics and Analysis
2017
In recent times, major cybersecurity breaches and cyber fraud had huge negative impact on victim organisations. The biggest impact made on major areas of business activities. Majority of organisations facing cybersecurity adversity and advanced threats suffers from huge financial and reputation loss. The current security technologies, policies and processes are providing necessary capabilities and cybersecurity mechanism to solve cyber threats and risks. However, current solutions are not providing required mechanism for decision making on impact of cybersecurity breaches and fraud. In this paper, we are reporting initial findings and proposing conceptual solution. The paper is aiming to pr…
