In this paper, we describe an innovative approach for aligning the business layer and the application layer of ArchiMate to ensure that applications manage access rights consistently with enterprise goals and risk tolerances. The alignment is realized ...

Virtual Machines have gained immense popularity amongst the Security Researchers and Malware Analysts due to their pertinent design to analyze malware without risking permanent infection to the actual system carrying out the tests. This is because ...

Security policy is a main mechanism of information security management. While there are a lot of security-related standards and guidelines which specify requirements for high-level security policies, implementation of network security policy still ...

Many different approaches have been used to target Internet security throughout time. It is now easy to realize the attackers' motivational shifts from the early days of lonely, proud-based, virus development to the recent eras of cooperative Internet ...

Cognitive radio (CR) has been introduced to allow unlicensed users, or better known as secondary users (SUs), to exploit underutilised licensed spectrum owned by the primary users (PUs). The SUs perform channel sensing to check the state of the PUs in ...

Mobile ad hoc networks (MANETs) lacks enforcement of policy-based access control mechanism to restrict unauthorized accesses on the network resources. Policy-based security infrastructure in MANET is more complex than traditional network due to ...

Security issues in Vehicular Ad-Hoc Networks (VANETs) are important because of its diverse implications in safety related and congestion avoidance applications. A critical security problem in VANET is injection of false data, i.e. an attacker propagates ...

In this paper, we present the statistical test of randomness on the Light Encryption Device (LED) Block Cipher. LED is a lightweight block cipher with a 64-bit block size and variable key lengths from 64 to 128 bits (in multiple of 16 bits). The ...

One of the major security challenges in cloud computing is the detection and prevention of denial-of-service (DoS) attacks. In order to detect and prevent DoS attacks as well as other malicious activities at the network layer, we propose a framework ...

Up-to-date security scanners perform vulnerability detection and identification on the basis of indirect features. Exploitation instruments (for example, Metasploit Framework), which are used for further vulnerability validation, launch exploits ...

This work-in-progress paper presents an ensemble-based model for detecting and mitigating Distributed Denial-of-Service (DDoS) attacks, and its partial implementation. The model utilises network traffic analysis and MIB (Management Information Base) ...

The present medical era has seen quite a considerable amount of work been done in tele-monitoring that involves transmission of biomedical signals through wireless media. Exchange of information amongst various hospital systems and medical centers ...

The network traffic management is a key issue as many new emerging applications are flooding the network with their packets. Several time sensitive and low bandwidth applications run along with other time insensitive and bandwidth intensive ...

Network Intrusion Detection Systems (NIDS) intercept the traffic at an organization's network periphery to thwart intrusion attempts. Signature-based NIDS compares the intercepted packets against its database of known vulnerabilities and malware ...

This work proposes a new method of malware classification based on behavior features. We developed a proximity measure for programs, which takes into account WinAPI calls, their arguments, and files handled by these programs. Cluster analysis is used ...

Security breaches are increasing day by day as the technology is innovating and opening new doors. There are various counter measures to keep a check on them and one such method is the watermarking. Region based watermarking is the approach where an ...

The theorems about equal power knapsacks, components of which are the parametrical solution of Tarry-Ascot multistage Diophantine equation system or the numerical solution of such a system were formulated. Mathematical models of alphabet cryptosystems, ...

Present day malware shows stealthy and dynamic capability and avails administrative rights to control the victim computers. Malware writers depend on evasion techniques like code obfuscation, packing, compression, encryption or polymorphism to avoid ...

The present study considers the improvement of existing cryptanalytical methods in relation to Russian standard of GOST 28147-89 symmetric encryption. This paper researches encryption transformations in GOST 28147-89 algorithm constructed on the ...

Anomaly Based Network Intrusion Detection Systems (ANIDS) mechanisms are largely based on machine learning algorithms and have been found effective in detecting known as well as novel attacks. However, often these algorithms in isolation cannot ...

As the password based authentication systems are not able to meet the performance because they can be stolen, forgotten, cracked, sniffed and tampered with. Lateral thinking to this problem evolved the use of biometrics to authenticate the person ...

We propose an algorithm that shows improvement in computation timeof existing image encryption-decryption methods. The algorithm also introduces additional one-level of encryption key into the existing methods. Image compression properties of the DWT (...

In this paper we will consider the special research methodology of stateful filtering in firewalls. Analysis of TCP/IP protocols, which connected with stateful filtering, was carried out and particular tests for different types of implementation were ...

Neighbor Discovery Protocol (NDP) is one of the core protocol in IPv6 network. It provides facilities like Stateless Address Autoconfiguration (SLAAC), Neighbor unreachability Detection (NUD), address resolution (similar to ARP in IPv4) etc. Due to lack ...

Watermarking in images is necessary for authentication of digital library based applications, mostly. For efficient utilization of storage space and bandwidth of communication channel, compressed images ensuring fair amount of quality is employed. In ...

Real-time surveillance systems, dealing with lipreading, can benefit from a reduction in visual data to be processed. This reduces processing time and improves the efficiency of the system. These systems take features extracted from the mouth region for ...

Today, with more and more computers getting connected to public accessible networks like Internet, computer systems are more and more susceptible to attacks. There is a need of effective intrusion detection systems (IDS) to protect computers from these ...

In 1995, Naor and Shamir proposed a technique of secret sharing, called visual cryptography. In visual cryptography, the secret message is divided into shares which are copied onto transparencies and given to participants. In general k-out-of-n visual ...

The paper presents a novel framework for blind watermark detection on additive watermarking in Discrete Cosine Transform (DCT) domain. Watermarks which resist any attempt by an adversary to thwart their intended purpose such as unauthorized detection, ...

The secure information transmission is very important in the present scenario. Many intrusion detection system (IDS) have been developed in recent past which are based on either signature information or anomaly information. But all these systems do ...
