Networks with many users and a mature IT infrastructure are a favourite with hackers.Take, for example, the National University of Singapore (NUS), whose user population exceeds 40,000.
“A total of 105,546 intrusion attempts targeted at NUS were detected in 2006,” says Yong Fong Lian, manager, IT security, NUS. The university estimates that if every attack resulted in successful compromise of the network, a staggering 210,000 hours in productivity would be lost. And the potential cost of these man hours? A jaw dropping S$4.2 million (US$2.8 million), or S$350,000 (US$240,000) a month.
