When it comes to addressing risks to the security of enterprise data, a forthcoming report from the Identity Theft Resource Center suggests that companies may want to pay the most attention to network intrusions.

That's because, according to InformationWeek, the ITRC's analysis of 419 data breaches reported last year found that 26 percent were caused by hackers and a "targeted intrusion into a data network." Information lost in transit accounted for 18 percent of incidents, while 13 percent were caused by insider theft, the news provider reported.

When looking at events caused by both insiders and outsiders, the ITRC found that 40 percent of last year's data breaches were carried out with malicious intent.

Overall, more than 22.9 million records were exposed, with 81 percent of those being Social Security numbers. That suggests companies should be investing in technology to prevent these incidents.

A separate report from network security provider Palo Alto Networks also investigated the cause of breaches. It found that increased use of social networks and file sharing solutions among employees is another leading cause of security incidents.
