Major Security Issue That Facing Social Networks with Its Main Defense Strategies
The Social Network Service "SNS" has enabled significant advancements in a wide variety of scientific fields, and as a result, it has become an extremely popular subject in both academia and business. SNSs can be extremely beneficial to users because they eliminate economic and geographical barriers and can be used for job searching, entertainment and education. Regardless of the economic and social benefits, protecting businesses and users\u27 security and privacy remains a critical issue that must be addressed. It is critical to address and evaluate social network service challenges, as they vary according to the variety of SNS sites. Thus, by discussing SNS challenges alongside available and potential solutions, users, developers, and businesses can identify relevant and timely responses to specific threats, resulting in the best SNS-based services possible. The objective of this article is to discuss the inherent challenges of social networking sites and some critical solutions for resolving them. We extracted and analyzed seminal papers to add to the corpus of literature by focusing on several critical challenges in the social network service domain and shedding light on how these challenges affect a variety of domains, including users, sites, and business. The most frequently mentioned difficulties concerned privacy risks, anonymity risks, malware, spam, identity theft, phishing, business data, social content, technical issues, and psychological difficulties. By incorporating previously discovered solutions, this paper addressed these issues. The implications for both researchers and practitioners have been discussed
Adversarial Agents For Attacking Inaudible Voice Activated Devices
The paper applies reinforcement learning to novel Internet of Thing
configurations. Our analysis of inaudible attacks on voice-activated devices
confirms the alarming risk factor of 7.6 out of 10, underlining significant
security vulnerabilities scored independently by NIST National Vulnerability
Database (NVD). Our baseline network model showcases a scenario in which an
attacker uses inaudible voice commands to gain unauthorized access to
confidential information on a secured laptop. We simulated many attack
scenarios on this baseline network model, revealing the potential for mass
exploitation of interconnected devices to discover and own privileged
information through physical access without adding new hardware or amplifying
device skills. Using Microsoft's CyberBattleSim framework, we evaluated six
reinforcement learning algorithms and found that Deep-Q learning with
exploitation proved optimal, leading to rapid ownership of all nodes in fewer
steps. Our findings underscore the critical need for understanding
non-conventional networks and new cybersecurity measures in an ever-expanding
digital landscape, particularly those characterized by mobile devices, voice
activation, and non-linear microphones susceptible to malicious actors
operating stealth attacks in the near-ultrasound or inaudible ranges. By 2024,
this new attack surface might encompass more digital voice assistants than
people on the planet yet offer fewer remedies than conventional patching or
firmware fixes since the inaudible attacks arise inherently from the microphone
design and digital signal processing
Emulación de usuario primario en la red de radio cognitiva móvil: estudio
For emerging networks such as the mobile cognitive radio network, it is essential to study their possible attacks and thus generate detection strategies. Generally attacks are focused on only one layer of the OSI model, they have been studied for each layer from the physical level to the application level and have focused on fixed secondary users. In cognitive radio networks, the primary user emulation (PUE) is the most studied attack since it affects the entire cognitive cycle from the physical layer to the upper layers. This paper defines types of PUE attack and countermeasures, analyzing the effects on fixed and mobile secondary users and attackers.En el caso de las redes emergentes, como la red de radiocomunicaciones cognitivas móviles, es esencial estudiar sus posibles ataques y generar así estrategias de detección. Por lo general, los ataques se centran en una sola capa del modelo OSI, se han estudiado para cada capa desde el nivel físico hasta el nivel de aplicación y se han centrado en los usuarios secundarios fijos. En las redes de radiocomunicaciones cognitivas, la emulación de usuario primario (PUE) es el ataque más estudiado, ya que afecta a todo el ciclo cognitivo desde la capa física hasta las capas superiores. En este documento se definen los tipos de ataque PUE y las contramedidas, analizando los efectos en los usuarios secundarios fijos y móviles y en los atacantes
Electronic security - risk mitigation in financial transactions : public policy issues
This paper builds on a previous series of papers (see Claessens, Glaessner, and Klingebiel, 2001, 2002) that identified electronic security as a key component to the delivery of electronic finance benefits. This paper and its technical annexes (available separately at http://www1.worldbank.org/finance/) identify and discuss seven key pillars necessary to fostering a secure electronic environment. Hence, it is intended for those formulating broad policies in the area of electronic security and those working with financial services providers (for example, executives and management). The detailed annexes of this paper are especially relevant for chief information and security officers responsible for establishing layered security. First, this paper provides definitions of electronic finance and electronic security and explains why these issues deserve attention. Next, it presents a picture of the burgeoning global electronic security industry. Then it develops a risk-management framework for understanding the risks and tradeoffs inherent in the electronic security infrastructure. It also provides examples of tradeoffs that may arise with respect to technological innovation, privacy, quality of service, and security in designing an electronic security policy framework. Finally, it outlines issues in seven interrelated areas that often need attention in building an adequate electronic security infrastructure. These are: 1) The legal framework and enforcement. 2) Electronic security of payment systems. 3) Supervision and prevention challenges. 4) The role of private insurance as an essential monitoring mechanism. 5) Certification, standards, and the role of the public and private sectors. 6) Improving the accuracy of information on electronic security incidents and creating better arrangements for sharing this information. 7) Improving overall education on these issues as a key to enhancing prevention.Knowledge Economy,Labor Policies,International Terrorism&Counterterrorism,Payment Systems&Infrastructure,Banks&Banking Reform,Education for the Knowledge Economy,Knowledge Economy,Banks&Banking Reform,International Terrorism&Counterterrorism,Governance Indicators
Attacks On Near Field Communication Devices
For some years, Near Field Communication (NFC) has been a popularly known technology characterized by its short-distance wireless communication, mainly used in providing different agreeable services such as payment with mobile phones in stores, Electronic Identification, Transportation Electronic Ticketing, Patient Monitoring, and Healthcare. The ability to quickly connect devices offers a level of secure communication. That notwithstanding, looking deeply at NFC and its security level, identifying threats leading to attacks that can alter the user’s confidentiality and data privacy becomes obvious. This paper summarizes some of these attacks, emphasizing four main attack vectors, bringing out a taxonomy of these attack vectors on NFC, and presenting security issues alongside privacy threats within the application environment
