  1. 11. Effects of packet loss and delay on TCP performance
    Adam Lukasz Krajewski (Warsaw University of Technology (PL))
    24/03/2015, 12:20
    Security & Networking
    Following an incident with a slow database replication between CERN's data centers, we discovered that even a very low rate packet loss in the network (order of 0.001%) can induce significant penalties to long distance single stream TCP transfers. We explore the behaviour of multiple TCP congestion control algorithms in a controlled loss and delay environment in order to understand...

  2. 5. Computer Security update
    Mr Romain Wartel (CERN)
    24/03/2015, 14:00
    Security & Networking
    This presentation gives an overview of the current computer security landscape. It describes the main vectors of compromises in the academic community including lessons learnt, and reveal inner mechanisms of the underground economy to expose how our resources are exploited by organised crime groups, as well as recommendations to protect ourselves. By showing how these attacks are both...

  4. 35. Recent experiences in operational security: incident prevention and incident handling in the EGI and WLCG infrastructure
    Linda Ann Cornwall (STFC - Rutherford Appleton Lab. (GB))
    24/03/2015, 14:50
    Security & Networking
    The European Grid Infrastructure (EGI) and Worldwide Large Hadron collider Grid (WLCG) infrastructure largely overlap and share the majority of security activities. A lot of security related activity goes on behind the scenes concerning such a large scale distributed computing infrastructure. Security incident prevention takes up the larger amount of effort, and this is carried out via...

  5. 39. A recent view of OSSEC and Elasticsearch at Scotgrid Glasgow
    David Crooks (University of Glasgow (GB))
    24/03/2015, 15:15
    Security & Networking
    OSSEC, the popular HIDS (Host Intrusion Detection System), has been widely used for a number of years. More recently, tools like Elasticsearch, Logstash and Kibana (ELK) have become popular in visualising and working with data such as that aggregated by OSSEC. We report on a recent implementation of OSSEC, coupled to an ELK instance, at the Glasgow site of the UKI-SCOTGRID distributed Tier-2....

  6. 43. Update on WLCG/OSG perfSONAR Infrastructure
    Marian Babik (CERN)
    24/03/2015, 15:50
    Security & Networking
    WLCG relies on the network as a critical part of its infrastructure and therefore needs to guarantee effective network usage and prompt detection and resolution of any network issues, including connection failures, congestion and traffic routing. The WLCG Network and Transfer Metrics working group was established to ensure sites and experiments can better understand and fix networking issues....

  7. 34. News from the HEPiX IPv6 Working Group
    Dave Kelsey (STFC - Rutherford Appleton Lab. (GB))
    24/03/2015, 16:15
    Security & Networking
    This talk will present an update from the HEPiX IPv6 Working Group. This will include details of recent testing activities and plans for the deployment of dual-stack data services and monitoring on (at least some of) the WLCG infrastructure.

  8. 37. Testing dCache and IPv6
    Ulf Bobson Severin Tigerstedt (Helsinki Institute of Physics (FI))
    24/03/2015, 16:40
    Security & Networking
    A view back on testing IPv6 and different versions of dCache as it has evolved from 2.6 to 2.12 and barely-working to well working.

  9. 48. The IPV6 post office: labeling and sorting everywhere.
    Francesco Prelz (Università degli Studi e INFN Milano (IT))
    24/03/2015, 16:55
    Security & Networking
    Probably the most prominent change that IPv6 introduces in the semantics of internet protocol applications is the need to *always* deal with multiple addresses (possibly both IPv4 and IPv6) associated to each network endpoint. A quick overview of how and where addresses are categorised, ordered and preferred is presented, both from the system administrator and the developer viewpoint. A few...
