Long-time Slashdot reader doom writes: Over a two year period, a third of the IPv4 address space have experienced some sort of DoS attack, though the researchers who've ascertained this suspect this is an underestimate. This is from a story at Science Daily reporting on a Study recently presented in London at the Internet Measurement Conference. "As might be expected, more than a quarter of the targeted Addresses in the study came in the United States, the nation with the most internet addresses in the world. Japan, with the third most internet addresses, ranks anywhere from 14th to 25th for the number of Dos Attacks, indicating a relatively safe nation for DoS attacks..." The study itself states, "On average, on a single day, about 3% of all Web sites were involved in attacks (i.e., by being hosted on targeted IP addresses)." "Put another way," said the report's principal investigator, "during this recent two-year period under study, the internet was targeted by nearly 30,000 attacks per day."
