Data Handling and Storage Policy
All data accessed, stored, communicated or transferred on any national HPC system (e.g. Fram) and the National e-Infrastructure for Research Data (NIRD), must be handled in compliance to legal and regulatory requirements.
In addition, all data has to be directly related to the work effectuated and/or the research project(s) the user is participating.
User's private data (such as keys, sessions, e-mail, etc.) may reside in their home directory ($HOME). $HOME is not a shared area and all data stored there has to be treated as being private, regardless of it's content.
To limit access to $HOME only to the user and designated system administrators, the default directory permissions are set to 0700. Permissions are regularly controlled and in case of mismatch reset to defaults.
Project data is private to the project and shared between the project members. The project leader (PL) has sole discretion over project members, thus access to the project area(s).
Projects local to a particular HPC system has it's own directory, created with permissions set to 2770 to set the global group ID. Group ownership is regularly controlled for each project directory and reset in case needed. This is required for storage accounting purposes.
In special cases there might be a need for sharing data between projects for collaboration and possibly preventing data duplication.
If such a need is justified, a meta-group and it's according directory is created. Access to the shared project area is at the PL's sole discretion. For accounting purposes, the group ownerships are regularly controlled and in case needed reset.
