Welsh: actor seiberfygythiad

Status B

Subject: ICT

Part of speech: Noun, Masculine, Singular

Plural: actorion seiberfygythiad

Definition: Yng nghyd-destun seiberddiogelwch, person neu grŵp sy'n cymryd rhan mewn ymosodiad bwriadol neu faleisus ar gyfrifiaduron, dyfeisiau, systemau neu rwydweithiau ac yn ennill mynediad iddynt er mwyn peryglu, dwyn, newid neu ddinistrio gwybodaeth.

Notes: Weithiau gwelir y ffurf symlach 'threat actor' yn Saesneg. Argymhellir parhau i ddefnyddio 'actor seiberfygythiad' yn Gymraeg wrth drosi'r ffurf honno os mai seiberddiogelwch yw'r maes.
