The University of Sydney has called in two internet security firms to beef up protection of its computer networks after its home page was sabotaged and corporate webpages were altered during the weekend.
The home page was replaced on Saturday with an offensive message that taunted the site's administrator for lax security.

The website was shut for much of the weekend to prevent more attacks and an investigation is under way.

The university confirmed its website had been hacked three times during the past week but would not comment on the motive or whether security weaknesses remained.
