Classes at SETU Waterford will resume this morning, following a cyber attack last week.
Monday's classes were cancelled after its IT systems were targeted on Friday.
The University says they're continuing to actively deal with the attack.
Students' Union President at SETU, Mark Dunne, is warning some disruption may still arise.
"Students can resume classes from today, however they can expect some disruption to services such as internet connectivity and being able to print on campus," he said.
"Lectures will be going ahead as normal while we work through this process."
