A wnaiff y Prif Weinidog gadarnhau faint o ymosodiadau seiber a ddioddefodd Llywodraeth Cymru yn y blynyddoedd canlynol: 2015-16 a 2016-17 2017-18 hyd yma, gan gynnwys faint a ystyriwyd i fod yn ddigwyddiad diogelwch seiber/yn achos gwirioneddol o danseilio diogelwch?

There are continual cyber attacks on our ICT system, including email services, but the design and alignment with wider UK government security standards provides Welsh Government with a high-level of protection and have not led to any known successful cyber compromises during 2015-16, 2016-17 and 2017-18 to date.
