Intrusion detection is a problem of great significance to protecting information systems security. An intruder may move between multiple nodes in the network to conceal the origin of attack. Distributed intrusion detection and prevention plays an increasingly important role in securing computer networks. To overcome the limitations of conventional intrusion detection systems, alerts are made in...

At the Information-technology Promotion Agency (IPA), we have been developing a network intrusion detection system we have named IDA (for the Intrusion Detection Agent system). IDA has two distinctive features that most conventional intrusion detection systems lack. The rst feature is a mechanism for tracing the origin of the break-in by means of mobile agents. The second feature is the way in ...

Recently, Advanced Persistent Threat (APT) has emerged as sophisticated and tailor-made attacks. APTs pose threats mainly targeting institutions such military, defense security infrastructure, high profile companies governments etc. Particularly a counter measure for APT attacks done by hactivists cyber warriors terrorists over government e-government applications intrusion detection mechanisms...

The increasing number of network security related incidents makes it necessary for organizations to actively protect their sensitive data with the installation of intrusion detection systems (IDS). Autonomous software agents, especially when equipped with mobility, promise an interesting design approach for such applications. We evaluate the implications of applying mobile agent technology to t...

Given the recent emergence of the smart grid and smart grid related technologies, their security is a prime concern. Intrusion detection provides a second line of defence. However, conventional intrusion detection systems (IDSs) are unable to adequately address the unique requirements of the smart grid. This paper presents a gap analysis of contemporary IDSs from a smart grid perspective. This ...

The goal of Distributed Intrusion Detection System is to analyze events on the network and identify attacks. The increasing number of network security related incidents makes it necessary for organizations to actively protect their sensitive data with the installation of intrusion detection systems (IDS). There is a difficulty to find intrusion in an distributed network segment from inside as w...

The Paraíba is an Au-Cu-Mo deposit located in the southern part of Amazon Craton, Alta Floresta Mineral Province, Mato Grosso State, Brazil. It composed Au-Cu-bearing quartz veins and Cu-Mo-rich hydrothermal breccias stockworks, both associated with several alteration zones. integration spectral (reflectance imaging spectroscopy) conventional techniques (core logging, petrography, mineral chemi...
