System ownership for scientific systems is driven by the funding mechanism. Many systems are acquired though NWO and EU funding. The PI of the project is by definition the owner of the system. Both functional and technical management are in the hands of the IT Department.

For Servers and Desktops the ownership/user is recorded in the CMDB.

For non-scientific information systems, by definition the Scientific Director (see roles) is the owner. But he is allowed to delegate the responsibility to any of his subordinates.

New scientific informations systems will all fall in the 'basic risk' category. For information systems that store personel information extra security measures will be taken to adhere to the GDPR requirements.

There are no scientific systems with elevated risks. So no additional risk analysis measures have to be taken.

For information systems storing personel information additional analysis takes place to adhere to the GDPR requirements.

Information systems are implemented in close collaboration with the system owner, but no formal, written acceptance is in place. For systems 'owned' by system management, a team meeting is initiated to formally decide a 'GO' on becoming part of the operational system.

For all systems, server, desktops, stoarge and other devices security updates are implemented as a continuous process. Every day the software repositories are automatically interrogated for new security updates, which are then applied immediately.

Log files are stored local to the system where they are created. However, each log is analysed automatically and in case of a non-regular situation system managers are emailed with an indication of the non-regular behaviour. Upon receipt of such an incident the log on the system in question will be analysed. In case of a true irregularity an incident is initiated.

All systems use one set of time servers inside the IT Department server hardware to synchronize all clocks on all devices. The IT Department time servers themselves use international time servers to keep their time synchronized to the 'world'.

Security incidents are recorded in a mail folder of the IT Department Head.

The Security manager as defined by the roles is the responsible person for all incidents and works in collaboration with all team members to resolve the incident.

There is no true calamity procedure, and each case is handled ad hoc, with teh following requirements in mind:

• Minimize downtime of critical services
• Communicate the calamity to all users/steakholders
• Maximize the collaborative effort within the IT Department team
• Strive to full resolution of the calamity
