Security in HPC Centres

Securing the HPC infrastructure is an important task. The level of awareness regarding the importance of this topic is
high, but the level of investments and skills required to organise a proper protection make it a difficult task, with
contrasted levels of solutions and practices observed. There are a huge number of security threats coming from both the
Internet and internal networks and, despite the fact that it may seem as a high cost, it is crucial to introduce an adequate
level of security to the infrastructure, because the costs of losing data are usually much higher.
Based on a survey of the PRACE community, this paper describes security technologies used in data centres and
especially its subset, i.e. HPC centres. It gives a set of general recommendations concerning how to enhance security of
the HPC infrastructure.
