Internet Attacks Increase in Number, Severity

IBM's Global Business Security Index, which tracks worldwide security trends, indicated there is not only a decrease in less profitable threats like spam and computer viruses, but also an increase in attacks involving money, such as data theft or identity theft.
According to the report, there were more than 237 million overall security attacks in the first half of the year. The government was the most targeted sector, with over 54 million attacks leveled at government agencies. Manufacturing came in second place with over 36 million attacks.
A particularly notable trend is the number of attacks that are directed at specific individuals or companies, often with financial, competitive, political or social motivations behind them.
