Title Adapting Open Source tools to cater for a diverse computing infrastructure
Abstract The Scientific Computing Technology Group (SCT) computing infrastructure consists of many different functional services, ranging from high performance compute clusters such as SCARF (a facility run for all of STFC) and the National Service for Computational Chemistry Software (NSCCS), to e-Infrastructure like the UK National Grid Service (NGS), and VMware ESX virtualisation technologies. Alongside site wide STFC policies on security, SCT must also provision mechanisms to effectively manage and monitor the security of these services, seamlessly, with a consistent and cohesive approach. Open Source tools represent a cost effective opportunity to manage infrastructure but often prove inflexible over a heterogeneous collection of services. Additionally, where possible, SCT opt to deploy applications that are included as part of the Red Hat Enterprise Linux (RHEL) suite, as these are actively maintained and patched by Red Hat; this is primarily because all systems managed by SCT utilise RHEL or its Scientific Linux variant. This paper will focus on the efforts made to customise and enhance three Open Source tools: AIDE, Pakiti and Syslog-NG and how these changes have benefitted SCT while still remaining manageable and maintainable.
