Towards a generic platform for developing CSCL applications using Grid infrastructure
The goal of this paper is to explore the possibility of using CSCL component-based software under a Grid infrastructure. The merge of these technologies represents an attractive, but probably quite laborious enterprise if we consider not only the benefits but also the barriers that we have to overcome. This work presents an attempt toward this direction by developing a generic platform of CSCL components and discussing the advantages that we could obtain if we adapted it to the Grid. We then propose a means that could make this adjustment possible due to the high degree of genericity that our library component is endowed with by being based on the generic programming paradigm. Finally, an application of our library is proposed both for validating the adequacy of the platform which it is based on and for indicating the possibilities gained by using it under the Grid.Peer ReviewedPostprint (published version
WLCG Security Operations Centres Working Group
Security monitoring is an area of considerable interest for sites in the Worldwide LHC
Computing Grid (WLCG), particularly as we move as a community towards the use of
a growing range of computing models and facilities. There is an increasingly large set
of tools available for these purposes, many of which work in concert and use concepts
drawn from the use of analytics for Big Data. The integration of these tools into what
is commonly called a Security Operations Centre (SOC), however, can be a complex task
- the open source project Apache Metron (which at the time of writing is in incubator
stage and is an evolution of the earlier OpenSOC project) is a popular example of one
such integration. At the same time, the necessary scope and rollout of such tools can vary
widely for sites of different sizes and topologies. Nevertheless, the use of such platforms
could be critical for security in modern Grid and Cloud sites across all scientific disciplines.
In parallel, the use and need for threat intelligence sharing is at a key stage and is an
important component of a SOC. Grid and Cloud security is a global endeavour - modern
threats can affect the entire community, and trust between sites is of utmost importance.
Threat intelligence sharing platforms are a vital component to building this trust as well
as propagating useful threat data. The MISP software (Malware Information Sharing
Platform) is a very popular and
exible tool for this purpose, in use at a wide range of
organizations in different domains across the world.
In this context we present the work of the WLCG Security Operations Centres Work-
ing Group, which was created to coordinate activities in these areas across the WLCG.
The mandate of this group includes the development of a scalable SOC reference design
applicable for a range of sites by examining current and prospective SOC projects & tools.
In particular we report on the first work on the deployment of MISP and the Bro Intru-
sion Detection System at a number of WLCG sites as SOC components, including areas
of integration between these tools. We also report on our future roadmap and framework,
which includes the Apache Metron project
MAGDA: A Mobile Agent based Grid Architecture
Mobile agents mean both a technology
and a programming paradigm. They allow for a
flexible approach which can alleviate a number
of issues present in distributed and Grid-based
systems, by means of features such as migration,
cloning, messaging and other provided mechanisms.
In this paper we describe an architecture
(MAGDA – Mobile Agent based Grid Architecture)
we have designed and we are currently
developing to support programming and execution
of mobile agent based application upon Grid
systems
