(7)The soundness, resilience and protection of the information technology systems of trade repositories are essential to ensure compliance with the objectives of Regulation (EU) No 648/2012. Accordingly, trade repositories should provide comprehensive and more detailed information on those systems to enable ESMA to assess the soundness and resilience of their information technology systems. Where the provision of repository functions is outsourced to third parties, either at the level of the group or outside the group, trade repositories should provide detailed information on the relevant outsourcing arrangements to enable ESMA to assess compliance with the conditions for registration, including information on any service level agreements, on metrics and on how those metrics are effectively monitored. Finally, trade repositories should provide information on the mechanisms and controls that they put in place to effectively manage potential cyber-risks and to protect the data on cyber-attacks.
