The Australian Computer Emergency Response Team (AusCERT) presents its findings on trends in electronic attacks on Australian organisations in its annual Australian computer crime and security survey. In the latest survey, 389 organisations responded as to whether they had experienced one or more electronic attacks in the past 12 months. About one in five (22%) had experienced an electronic attack, down from more than one-third (35%) the year before and continuing a downward trend that began in 2004 (49%). Most of these (83%) were from external sources. The latest survey recorded a small increase in external attacks but a larger reduction in internal attacks compared with 2005 (81% external, 37% internal). Across most categories of electronic attack, there was a reduction in the level of activity detected, with the proportion of organisations that did not experience an attack (73%) continuing to grow (61% in 2005, 49% in 2004). Just 10 percent of businesses thought they were managing all aspects of computer security well, an improvement on 2005 (7%) and 2004 (5%).
