Web services are expected to play significant role for message communications over internet applications. Most of the future work is web security. Online shopping and web services are increasing at rapid rate. In this paper we presented the fundamental concepts related to Network security, web security threats. QoS web service security intrusion detection is important concern in network communi...

Information technology (IT) security has become a major concern due to the growing demand for information and massive development of client/server applications for various types of applications running on modern IT infrastructure. How has security been taken into account and which paradigms are necessary to minimize security issues while increasing efficiency, reducing the influence on transmis...

The concept of combining security and error control codes is appealing, especially in applications where latency is a concern, or resources are limited. However, there are many difficulties in combining these two coding paradigms. Often, security and error control work at cross-purposes to each other, making combined schemes based on existing security models difficult to develop. Thus, most of ...

Network security has become more important to personal computer users, organizations, and the military. With the advent of the internet, security became a major concern and the history of security allows a better understanding of the emergence of security technology. The architecture of the internet, when modified can reduce the possible attacks that can be sent across the network. Knowing the ...

Security concern for a Sensor Networks and level of security desired may differ according to application specific needs where the sensor networks are deployed. Till now, most of the security solutions proposed for sensor networks are layer wise i.e a particular solution is applicable to single layer itself. So, to integrate them all is a new research challenge. In this paper we took up the chal...

Session Initiation Protocol (SIP) is a signaling standard approved by IETF for real-time multimedia session establishment. Increasingly wide deployment brings much concern on SIP security. Current solutions for end-to-end signaling security either require user-side powerful performance support for heterogeneous security mechanisms, or assume that trust relationship is transitive and static. Yet...

Security is becoming a more and more important concern for software architecture and software components. Previous modeling approaches provide insufficient support for an indepth treatment of security. This paper argues for a more comprehensive treatment of an important security aspect, access control, at the architecture level. Our approach models security subject, resource, privilege, safegua...

Agile methods are widely employed to develop high-quality software, but theoretical analyses argue that agile methods are inadequate for security-critical projects. However, most agiledeveloped software today needs to satisfy baseline security requirements, so that we need to focus on how to achieve this level for typical agile projects. Software grows up through its life cycle, so software dev...

Recently security has became one of the major concern in Information System (IS) development. Different security modeling language or security extension is used to model security features of IS. Mal Activity Diagram (MAD) is used at the design stage to represent security aspect. But it cannot model all the security risk management concepts. Without full coverage of concepts, it is not possible ...
