Over the years, the focus has been on protecting network, host, database and standard applications from internal and external threats. The Rapid Application Development (RAD) process makes the web application extremely short and makes it difficult to eliminate the vulnerabilities. Here we study web application risk assessment technique called threat risk modeling to improve the security of the ...

To improve the information authentication and network security one of the effective authentication mechanism is Biometric authentication System. But when this authentication system is a offline authentication system, in such case, it is required to secure this authentication information. In this work, a biometric watermarking based authentication system is defined to secure the authentication s...

Secret and secure delivery of message is most important issue in field of security hence signcryption were used. The term signcryption is referred as a technique of encrypting the data with the use of signatures in area of public key cryptography. A signcryption technique is a combination of digital signature which is used for authentication and public key cryptography which is used for securin...

A mobile agent is a software code with mobility which can be move from a computer into another computers through network. The mobile agent paradigm provides many benefits in developments of distributed application at the same time introduce new requirements for security issues with these systems. In this article we present a solution for protection agent from other agents attacks with loging pa...

Many network servers rely on the correctness and security of closed protocols. However, the unavailability of the protocol specification hinders any attempt to adequately test the implementations of that protocol. The paper addresses this problem by complementing an attack injection methodology with a protocol reverse engineering component. We introduce a new approach to automatically infer the...

We propose a network implementation with enhanced security at the physical layer by means of time-hopping CDMA, supporting cryptographically secure point-to-point and point-to-multipoint communication. In particular, we analyze an active star topology optical network implementation capable of supporting 128 simultaneous users up to 20 km apart. The feasibility of the proposed scheme is demonstr...

Neural network is information processing paradigm that is inspired by the way biological nervous system process information like brain. It acts as a powerful modelling when the resulting outcome is unknown. In this paper we are using neural network in order to estimate most miscellaneous issues of software engineering such as testing, security etc. Neural network can recognize and learn mutual ...

Quantifying security risk is an important and yet difficult task in enterprise network risk management, critical for proactive mission assurance. Even though metrics exist for individual vulnerabilities, there is currently no standard way of aggregating such metrics. We developed a quantitative model that can be used to aggregate vulnerability metrics in an enterprise network, with a sound comp...
