Insider Security Breaches Increase

By Ericka Chickowski on 2009-06-26


The Identity Theft Resource Center (ITRC) has released its mid-year analysis of major data breaches reported so far in 2009. Though the total numbers show an improvement over the first half of 2008, ITRC is reporting the percentage of insider attacks and breaches caused by hacking is on the rise. As it does with all of its reports, ITRC warns users to remember that the number of reported breaches is likely just the tip of the iceberg when it comes to actual breach statistics. Many more incidents go unreported.
