Breaches of electronic records last year involved more insider threats, greater use of social engineering and the continued strong involvement of organized criminal groups, according to communication giant Verizon‘s 2010 Data Breach Investigations Report, in collaboration with the U.S. Secret Service. However, the overall number of breaches investigated last year declined from the previous year—”a promising” indication, the study said.
The report found most data breaches investigated were caused by external sources: Sixty-nine percent of breaches resulted from these sources, while only 11 percent of breaches were linked to business partners. The study said insiders caused 49 percent of breaches, which is an increase over previous report findings, primarily due to an expanded dataset and the types of cases studied by the Secret Service, Verizon said.
Many breaches involved privilege misuse, the report stated, with 48 percent of breaches attributed to users who, for malicious purposes, abused their right to access corporate information. An additional 40 percent of breaches were the result of hacking, while 28 percent were due to social tactics and 14 percent to physical attacks. The reported said as in previous years, nearly all data was breached from servers and online applications, with 85 percent of breaches not considered highly difficult; 87 percent of victims had evidence of the breach in their log files, yet missed it.
