: IoT is the networking of daily use objects. These objects are commonly known as constrained devices. Constrained devices works with low memory, low storage, and low computation power. Implementing security algorithms in these devices is challenging. The researchers take these challenges as opportunity. The diverse and heterogeneous structure of the IoT phenomenon introduces a variety of new security risks and challenges. Many threats such as botnets, home intrusion, remote control of the IoT devices, and man-in-the-middle attack are threatening the IoT environment. Hence it needs a stronger security implementation to protect IoT devices from being compromised. The authors surveys different kinds of networking technologies under an IoT environment, security challenges on them and possible countermeasures for these challenges to form a more secure IoT environment for trustful adoptation of services through industrial or personal use. In this paper, the authors presented the study of numerous networking technologies along with possible threats and their countermeasures.

Information security within healthcare is paramount and telemedicine applications present unique security challenges. Technology is giving rise to new and advanced telemedicine applications and understanding the security threats to these applications is needed to ensure, among other things, the privacy of patient information. This paper proposes a threat table approach to assess security threats pertaining to telemedicine applications. The concept and its usefulness are illustrated using a case study. This case study focuses on the capture and representation of salient security threats in telemedicine. To analyze the security threats to an application, it presents a threat modeling framework utilizing a table driven approach. The study reveals that even in a highly controlled environment with static locations, the security risks posed by telemedicine applications are significant, and that using a threat table approach provides an easy-to-use and effective method for managing these threats.

Securing cyber infrastructures has become critical because they are increasingly exposed to attackers while accommodating a huge number of IoT devices and supporting numerous sophisticated emerging applications. Security metrics are essential for assessing the security risks and making effective decisions concerning system security. Many security metrics rely on mathematical models, but are mainly based on empirical data, qualitative methods, or compliance checking, and this renders the outcome far from satisfactory. Computing the probability of an attack, or more precisely a threat that materialises into an attack, forms an essential basis for a quantitative security metric. This paper proposes a novel approach to compute the probability distribution of cloud security threats based on a Markov chain and Common Vulnerability Scoring System. Moreover, the paper introduces the method to estimate the probability of security attacks. The use of the new security threat model and its computation is demonstrated through their application to estimating the probabilities of cloud threats and types of attacks.


In a typical IoT network, a sensor connects to a controller using a wireless connection. Controllers collect data from sensors and sends the data for storage and analysis[1]. These controllers work with actuators that translate an electrical input to a physical action. The internet of things (IoT), have found application in different areas of human endeavor including healthcare, government, supply chain, cities, manufacturing, etc. and it is estimated that the number of connected devices will reach 50 billion by 2020[2] With the increasing number of devices comes an increase in the the varying number of security threats to the IoT network [3]. To contain these threats, a secure-by-design approach should be adopted as this will help the IoT devices to anticipate and neutralize the ever changing nature of the threats as against older systems where security was handled as it presents itself [2] This paper x-rays the security challenges in IoT networks and the application of machine learning (Supervised learning, Unsupervised learning and Reinforcement learning) in tackling the security challenges

The Internet of things (IoT) technology, which is currently considered the new growth engine of the fourth industrial revolution, affects our daily life and has been applied to various industrial fields. Studies on overcoming the limitations of scalability and stability in a centralized IoT operating environment by employing distributed blockchain technology have been actively conducted. However, the nature of IoT that ensures connectivity with multiple objects at any time and any place increases security threats. Further, it extends the influence of the cyber world into the physical domain, resulting in serious damage to human life and property. Therefore, we aim to study a method to increase the security of IoT devices and effectively extend them simultaneously. To this end, we analyze the authentication methods and limitations of traditional IoT devices and examine cases for improving IoT environments by using blockchain technology. Accordingly, we propose a framework that allows IoT devices to be securely connected and extended to other devices by automatically evaluating security using blockchain technology and the whitelist. The method proposed in this paper restricts the extension of devices vulnerable to security risks by imposing penalties and allows only devices with high security to be securely and quickly authenticated and extended without user intervention. In this study, we applied the proposed method to IoT network simulation environments and observed that the number of devices vulnerable to security was reduced by 48.5% compared with traditional IoT environments.

As useful as it gets to connect devices to the internet to make life easier and more comfortable, it also opens the gates to various cyber threats. The connection of Smart Home devices to the internet makes them vulnerable to malicious hackers that infiltrate the system. Hackers can penetrate these systems and have full control over devices. This can lead to denial of service, data leakage, invasion of privacy, etc. Thus security is a major aspect of Smart home devices. However, many companies manufacturing these Smart Home devices have little to no security protocols in their devices. In the process of making the IoT devices cheaper, various cost-cutting is done on the security protocols in IoT devices. In some way, many manufactures of the devices don’t even consider this as a factor to build upon. This leaves the devices vulnerable to attacks. Various authorities have worked upon to standardize the security aspects for the IoT and listed out guidelines for manufactures to follow, but many fail to abide by them. This paper introduces and talks about the various threats, various Security threats to Smart Home devices. It takes a deep dive into the solutions for the discussed threats. It also discusses their prevention. Lastly, it discusses various preventive measures and good practices to be incorporated to protect devices from any future attacks.

Nepal has been a home to diversified settlement in terms of ethnicity, religion, dialect and culture since its outset in civilization. It also lies between two great military and economic giants of Asia – India and China – that are hostile to each other. While these bring abundant opportunities for Nepal, it possesses several internal and external security threats. Nepal suffers from cyber-attack, environmental degradation, pandemic, ethnic, racial or religious conflicts, inequality and poverty, extremism, human trafficking, corruption, migration and trans-boundary crime. In addition, Nepal also faces several security threats, traditional and non–traditional, including terrorism and insurgency. These threats possess serious implications on peace and security of Nepal and the South Asian region. There is a need of serious study about the major internal and external security challenges that Nepal faces in recent decades. This study aims at examining some of the major security challenges, explore the factors behind it, and attempt to suggest few policy recommendations to the government of Nepal to deal with them. The study is conducted by reviewing the primary and secondary sources of data. The primary data includes documents of the government agencies, press release, joint statement and organizational reports. It also includes the interviews with security experts, bureaucrats, policy makers and academicians. Similarly, secondary data includes books, news reports, academic journals, seminars report and reports of research institutes and think tanks. The study highlights that Nepal should prepare itself to meet with the emerging internal and external security challenges what have emerged in recent times. With the rise of India and China, two adversarial powers in the region, Nepal possess extreme challenges in days to come. Similarly, hardly any countries of the world had prepared itself to deal with recent pandemic like COVID-19 that has shattered even the most powerful countries of the world. Taking lessons from these, it is time for Nepal to learn and prepare to mitigate the challenges.
