Internet of Things (IoT) is a revolutionary expandable network which has brought many advantages, improving the Quality of Life (QoL) of individuals. However, IoT carries dangers, due to the fact that hackers have the ability to find security gaps in users' IoT devices, which are not still secure enough and hence, intrude into them for malicious activities. As a result, they can control many connected devices in an IoT network, turning IoT into Botnet of Things (BoT). In a botnet, hackers can launch several types of attacks, such as the well known attacks of Distributed Denial of Service (DDoS) and Man in the Middle (MitM), and/or spread various types of malicious software (malware) to the compromised devices of the IoT network. In this paper, we propose a novel hybrid Artificial Intelligence (AI)-powered honeynet for enhanced IoT botnet detection rate with the use of Cloud Computing (CC). This upcoming security mechanism makes use of Machine Learning (ML) techniques like the Logistic Regression (LR) in order to predict potential botnet existence. It can also be adopted by other conventional security architectures in order to intercept hackers the creation of large botnets for malicious actions.
The quantity of Internet of Things (IoT) devices in the marketplace and lack of security is staggering. The interconnectedness of IoT devices has increased the attack surface for hackers. "White Worm" technology has the potential to combat infiltrating malware. Before white worm technology becomes viable, its capabilities must be constrained to specific devices and limited to non-harmful actions. This paper addresses the current problem, international research, and the conflicting interest of individuals, businesses, and governments regarding white worm technology. Proposed is a new perspective on utilizing white worm technology to protect the vulnerability of IoT devices, while overcoming its challenges.
There has been a growing spate of Cyber attacks targeted at different corporate enterprises and systems across the globe. The scope of these attacks spans from small scale (grid and control system manipulation, domestic meter cyber hacking etc) to large scale distributed denial of service attacks (DDoSA) in enterprise networks. The effect of hacking on control systems through distributed control systems (DCS) using communication protocols on vulnerable home area networks (HANs) and neighborhood area networks (NANs) is terrifying. To meet the current security requirements, a new security network is proposed called Smart grid convoluted network (SGCN). With SGCN, the basic activities of data processing, monitoring and query requests are implemented outside the grid using Fog computing layer-3 devices (gatekeepers). A cyber monitor agent that leverages a reliable end-to end-communication network to secure the systems components on the grid is employed. Cyber attacks which affects the computational requirements of SG applications is mitigated by using a Fourier predictive cyber monitor (FPCM). The network uses flexible resources with loopback services shared across the network. Serial parallelism and efficient bandwidth provisioning are used by the locally supported Fog nodes within the SG cloud space. For services differentiation, SGCN employed secure communication between its various micro-grids as well as its metering front-ends. With the simulated traffic payload extraction trend (STPET), SGCN promises hard time for hackers and malicious malwares. While the work guarantees security for SGs, reliability is still an open issue due to the complexity of SG architecture. In conclusion, the future of the Cyber security in SGs must employ the concept of Internet of Everything (IoE), Malware predictive analytics and Fog layers on existing SG prototypes for optimal security benefits.
Nowadays, with the rapid development of Internet, the use of Web is increasing and the Web applications have become a substantial part of people's daily life (e.g. E-Government, E-Health and E-Learning), as they permit to seamlessly access and manage information. The main security concern for e-business is Web application security. Web applications have many vulnerabilities such as Injection, Broken Authentication and Session Management, and Cross-site scripting (XSS). Subsequently, web applications have become targets of hackers, and a lot of cyber attack began to emerge in order to block the services of these Web applications (Denial of Service Attach). Developers are not aware of these vulnerabilities and have no enough time to secure their applications. Therefore, there is a significant need to study and improve attack detection for web applications through determining the most significant factors for detection. To the best of our knowledge, there is not any research that summarizes the influent factors of detection web attacks. In this paper, the author studies state-of-the-art techniques and research related to web attack detection: the author analyses and compares different methods of web attack detections and summarizes the most important factors for Web attack detection independent of the type of vulnerabilities. At the end, the author gives recommendation to build a framework for web application protection.
In recent years, cyber security threats have become increasingly dangerous. Hackers have fabricated fake emails to spoof specific users into clicking on malicious attachments or URL links in them. This kind of threat is called a spear-phishing attack. Because spear-phishing attacks use unknown exploits to trigger malicious activities, it is difficult to effectively defend against them. Thus, this study focuses on the challenges faced, and we develop a Cloud-threat Inspection Appliance (CIA) system to defend against spear-phishing threats. With the advantages of hardware-assisted virtualization technology, we use the CIA to develop a transparent hypervisor monitor that conceals the presence of the detection engine in the hypervisor kernel. In addition, the CIA also designs a document pre-filtering algorithm to enhance system performance. By inspecting PDF format structures, the proposed CIA was able to filter 77% of PDF attachments and prevent them from all being sent into the hypervisor monitor for deeper analysis. Finally, we tested CIA in real-world scenarios. The hypervisor monitor was shown to be a better anti-evasion sandbox than commercial ones. During 2014, CIA inspected 780,000 mails in a company with 200 user accounts, and found 65 unknown samples that were not detected by commercial anti-virus software.
Advanced Persistent Threat (APT), unlike traditional hacking attempts, carries out specific attacks on a specific target to illegally collect information and data from it. These targeted attacks use special-crafted malware and infrequent activity to avoid detection, so that hackers can retain control over target systems unnoticed for long periods of time. In order to detect these stealthy activities, a large-volume of traffic data generated in a period of time has to be analyzed. We proposed a scalable solution, Ctracer to detect stealthy command and control channel in a large-volume of traffic data. APT uses multiple command and control (C&C) channel and change them frequently to avoid detection, but there are common signatures in those C&C sessions. By identifying common network signature, Ctracer is able to group the C&C sessions. Therefore, we can detect an APT and all the C&C session used in an APT attack. The Ctracer is evaluated in a large enterprise for four months, twenty C&C servers, three APT attacks are reported. After investigated by the enterprise's Security Operations Center (SOC), the forensic report shows that there is specific enterprise targeted APT cases and not ever discovered for over 120 days.
Analysing cyber attack environments yield tremendous insight into adversory behavior, their strategy and capabilities. Designing cyber intensive games that promote offensive and defensive activities to capture or protect assets assist in the understanding of cyber situational awareness. There exists tangible metrics to characterizing games such as CTFs to resolve the intensity and aggression of a cyber attack. This paper synthesizes the characteristics of InCTF (India CTF) and provides an understanding of the types of vulnerabilities that have the potential to cause significant damage by trained hackers. The two metrics i.e. toxicity and effectiveness and its relation to the final performance of each team is detailed in this context.
The Communities vary from country to country. There are civil societies and rural communities, which also differ in terms of geography climate and economy. This shows that the use of social networks vary from region to region depending on the demographics of the communities. So, in this paper, we researched the most important problems of the Social Network, as well as the risk which is based on the human elements. We raised the problems of social networks in the transformation of societies to another affected by the global economy. The social networking integration needs to strengthen social ties that lead to the existence of these problems. For this we focused on the Internet security risks over the social networks. And study on Risk Management, and then look at resolving various problems that occur from the use of social networks.
By identifying memory pages that external I/O operations have modified, a proposed scheme blocks malicious injected code activation, accurately distinguishing an attack from legitimate code injection with negligible performance impact and no changes to the user application.
