Protecting grids from cross-domain attacks using Security alert sharing mechanisms
Future Generation Computer Systems, 2013Co-Authors: Raheel Hassan Syed, Maxime Syrame, Julien BourgeoisAbstract:In single administrative domain networks there is only one Security policy which can be evaluated by the IT Security manager, thanks to monitoring and reporting tools. Grid networks are often composed of different administrative domains owned by different organizations dispersed globally. Such networks are referred to as multi-administrative domain networks. Each domain might have its own Security policy and may not want to share its Security data with less-protected networks, making it more complex to ensure the Security of such networks and protecting them from cross-domain attacks. We propose a Security Event Manager (SEM) called the Grid Security Operation Center (GSOC), which facilitates IT Security managers in giving a view of the Security of the whole grid network without compromising confidentiality of Security data. To do so, GSOC provides a Security evaluation of each administrative domain (AD) and a parametric Security alert sharing scheme. Alert sharing can then be tuned in order to meet local Security policy rules. Highlights� Security evaluation is proposed in order to assign Security levels to the members of one grid. � Security alert sharing is presented which helps in blocking cross-domain attacks. � Alert sharing mechanism gives a global view of Security of the entire grid computing network.

SECRYPT - Managing Security of Grid Architecture with a Grid Security Operation Center.
2009Co-Authors: Julien Bourgeois, Syed Raheel HassanAbstract:Due to the nature of grid computing networks, Security pitfalls are plethora and adversaries are sneaking to launch attacks. Keeping this scope in mind, we will discuss our proposed solution for securing grid computing networks that we have called gSOC (Grid Security Operation Center). The main advantage of gSOC is that it can give a global view of Security of the entire grid infrastructure. The main difficulty is to deal with the specificities of grid infrastructure, that are: multi-sites networks, multi-administrative domains, dynamic collaboration between nodes and sites, high number of nodes to manage, no clear view of the foreign networks and exchange of Security information among different domains. Key-words: Grid Security, Grid Security Operation Center, Specificities of Grid Networks.

En gardant cela a la portee l’esprit, nous allons discuter de notre proposition de solution pour la securisation de reseaux informatique en grille que nous avons appele GSOC (Grid Security Operation Center). Le principal avantage de GSOC est qu’il peut donner une vision globale de la securite de l’infrastructure de grille entiere. La principale difficulte est de traiter les specificites des infrastructures de reseau, qui sont: les reseaux multi-sites, multi-domaines administratifs, une collaboration dynamique entre les nœuds et les sites, le nombre eleve de nœuds a gerer, pas de vision claire des reseaux etrangers et l’echange d’informations de securite entre les differents domaines.

Log-based Distributed Intrusion Detection for Hybrid Networks
2008Co-Authors: Francoise Sailhan, Julien BourgeoisAbstract:We propose a novel hybrid distributed Security Operation center which collects logs that are generated by any application, service, and protocol regardless of the layer of the protocol stack and the device (e.g., router); providing a global view of the supervised system based on which complex and distributed intrusions can be detected. Our HDSOC further (i) distributes its capabilities and (ii) provides extensive coordination capabilities for guarantying that both the network and the HDSOC components do not constitute isolated entities largely unaware of each others.

Defining a simple metric for real-time Security level evaluation of multi-sites networks
2008Co-Authors: Abdoul-karim Ganame, Julien BourgeoisAbstract:In previous research work, we have developed a cen- tralized Security Operation Center (SOC) [2] and a dis- tributed SOC [4]. These environments are very useful to react to intrusions or to analyze Security problem be- cause they provide a global view of the network without adding any kinds of software on network components. They therefore lack the possibility to have a real-time metric which measures the Security health of the differ- ent sites. The idea is to have, in one look, an indication of the Security level of all the sites of the network. In this article, we propose to define such a metric which gives the user 3 states for a given network.

boolean logic tree of label free dual signal electrochemical aptasensor system for biosensing three state logic computation and keypad lock Security Operation
Analytical Chemistry, 2017Co-Authors: Jiao Yang Lu, Xin Xing Zhang, Wei Tao Huang, Xue Zhi Ding, Nian Bing LiAbstract:The most serious and yet unsolved problems of molecular logic computing consist in how to connect molecular events in complex systems into a usable device with specific functions and how to selectively control branchy logic processes from the cascading logic systems. This report demonstrates that a Boolean logic tree is utilized to organize and connect “plug and play” chemical events DNA, nanomaterials, organic dye, biomolecule, and denaturant for developing the dual-signal electrochemical evolution aptasensor system with good resettability for amplification detection of thrombin, controllable and selectable three-state logic computation, and keypad lock Security Operation. The aptasensor system combines the merits of DNA-functionalized nanoamplification architecture and simple dual-signal electroactive dye brilliant cresyl blue for sensitive and selective detection of thrombin with a wide linear response range of 0.02–100 nM and a detection limit of 1.92 pM. By using these aforementioned chemical events ...

Boolean Logic Tree of Label-Free Dual-Signal Electrochemical Aptasensor System for Biosensing, Three-State Logic Computation, and Keypad Lock Security Operation
2017Co-Authors: Xin Xing Zhang, Wei Tao Huang, Xue Zhi Ding, Qiu Yan Zhu, Li Qiu Xia, Hong Qun LuoAbstract:The most serious and yet unsolved problems of molecular logic computing consist in how to connect molecular events in complex systems into a usable device with specific functions and how to selectively control branchy logic processes from the cascading logic systems.

By using these aforementioned chemical events as inputs and the differential pulse voltammetry current changes at different voltages as dual outputs, a resettable three-input biomolecular keypad lock based on sequential logic is established. Moreover, the first example of controllable and selectable three-state molecular logic computation with active-high and active-low logic functions can be implemented and allows the output ports to assume a high impediment or nothing (Z) state in addition to the 0 and 1 logic levels, effectively controlling subsequent branchy logic computation processes. Our approach is helpful in developing the advanced controllable and selectable logic computing and sensing system in large-scale integration circuits for application in biomedical engineering, intelligent sensing, and control
