Abstract:

Today, most businesses are based on a computer system, more or less developed. For daily activities the organization needs to be able to connect to the Internet, possibly from a local area network (LAN). But, once with the benefits of the Internet, there are also security risks that the organization must minimize by measures and appropriate controls. Among security issues arising from using the Internet include hacker attacks, computers infection with viruses, malware and spyware. In theory, hackers can enter inside the organization network and steal confidential data, damaging computers or th

Abstract:

The development of technology in computer networks has boosted the percentage of cyber-attacks today. Hackers are now able to penetrate even the strongest IDS and firewalls. With the help of anti-forensic techniques, attackers defend themselves, from being tracked by destroying and distorting evidences. To detect and prevent network attacks, the main modus of operandi in network forensics is the successful implementation and analysis of attack graph from gathered evidences. This paper conveys the main concepts of attack graphs, requirements for modeling and implementation of graphs. It also co

Abstract:

Security has become one of the important factors for any network communication and transmission of data packets. An organization with an optimal security system can lead to a successful business and can earn huge profit on the business they are doing. Different network devices are linked to route, compute, monitor, and communicate various real-time developments. The hackers are trying to attack the network and want to draw the organization’s significant information for its own profits. During the communication, if an intrusion or eavesdropping occurs, it will lead to a severe disfigurement of

The second phase generates hybrid keys by mixing a Zaslavsky and a 3D Hanon map that are used to encrypt the gray image values produced after the scramble. Finally, in the third phase, a new algorithm is suggested to hide the encrypted gray image at random locations within

Securing a safety-critical system is a challenging task, because safety requirements have to be considered alongside security controls. We report on our experience to develop a security architecture for railway signalling systems starting from the bare safety-critical system that requires protection. We use a threat-based approach to determine security risk acceptance criteria and derive security requirements. We discuss the executed process and make suggestions for improvements. Based on the security requirements, we develop a security architecture. The architecture is based on a hardware pla

Abstract:

Epidemiological dynamics is a vital method in studying the spread of computer network viruses. In this paper, an optimal control measure is proposed based on the SEIR virus propagation model in point-to-group information networks. First, considering the need for antivirus measures in reality, an optimal control problem is introduced, and then a controlled computer virus spread model in point-to-group information networks is established. Second, the optimal control measure is formulated by making a tradeoff between control cost and network loss caused by virus intrusion. Third, optimal control

Abstract:

Wireless sensor networks (WSNs) have attracted a lot of researchers due to their high potential in critical applications. WSNs are currently being employed in a variety of applications ranging from medical to military, and from home to industry. WSNs have unique constraints as compared to traditional networks making the implementation of existing security measures not practicable. These constraints are the result of limitations regarding the sensor nodes' memory, energy and transmission and processing power. So, traditional security mechanisms with large overhead of computation and communicati

Abstract:

It is increasingly difficult to manage the user identities (IDs) of rapidly developing and numerous types of online web-based applications in the present era. An innovative ID management system is required for managing the user IDs. The OpenID lightweight protocol is a better solution to manage the user IDs. In an OpenID communication environment, OpenID URL is not secured in a session hijacking situation because in other existing OpenID communication methods such double factor authentication has more chances of valid user session hijacked. The proposed communication protocol secures the OpenI

Abstract:

Since its inception, Bitcoin has been subject to numerous thefts due to its enormous economic value. Hackers steal Bitcoin wallet keys to transfer Bitcoin from compromised users, causing huge economic losses to victims. To address the security threat of Bitcoin theft, supervised learning methods were used in this study to detect and provide warnings about Bitcoin theft events. To overcome the shortcomings of the existing work, more comprehensive features of Bitcoin transaction data were extracted, the unbalanced dataset was equalized, and five supervised methods—the k-nearest neighbor (KNN), s

Abstract:

The convergence of automobiles and ICT (information and communication technology) has become a new paradigm for the development of next-generation vehicles. In particular, connected cars represent the most in-demand automobile-ICT convergence technology. With the development of 5G technology, communication between vehicle and external device using autonomous driving and Internet of things (IoT) technology has been remarkably developed. Control of vehicles using smart phones has become a routine feature, and over 200 Android apps are in use. However, Android apps are easy to tamper by repackagi

Abstract:

The applications of a mobile ad hoc network (MANET) range from military and disaster response to commercial and civilian environments. The intrinsic characteristics like lack of infrastructure, self-organizing nature and deployment flexibility contributes to its usefulness but few other features like open media for communication and topological changes on-the-fly makes it vulnerable to security attacks. The focus of the current work is security mechanisms for a MANET against the various insider attacks targeting the data forwarding operations. It is accomplished through a trust management fram

Abstract:

Security measure is of great importance in both steganography and steganalysis. Considering that statistical feature perturbations caused by steganography in an image are always nondeterministic and that an image is considered nonstationary, in this paper, the steganography is regarded as a fuzzy process. Here a steganographic security measure is proposed. This security measure evaluates the similarity between two vague sets of cover images and stego images in terms of n-order Markov chain to capture the interpixel correlation. The new security measure has proven to have the properties of boun

Autonomic computing paradigm is based on intelligent computing systems that can autonomously take actions under given conditions. These technologies have been successfully applied to many problem domains requiring autonomous operation. One such area of national interest is SCADA systems that monitor critical infrastructures such as transportation networks, large manufacturing, business and health facilities, power generation, and distribution networks. The SCADA systems have evolved into a complex, highly connected system requiring high availability. On the other hand, cyber threats to these i

Abstract:

Intrusion Detection System (IDS) is an important part of ensuring network security. When the system faces network attacks, it can identify the source of threats in a timely and accurate manner and adjust strategies to prevent hackers from intruding. Efficient IDS can identify external threats well, but traditional IDS has poor performance and low recognition accuracy. To improve the detection rate and accuracy of IDS, this paper proposes a novel ACGA-BPNN method based on adaptive clonal genetic algorithm (ACGA) and backpropagation neural network (BPNN). ACGA-BPNN is simulated on the KDD-CUP’99
