Human Negligence to Blame for the Majority of Insider ThreatsHuman Negligence to Blame for the Majority of Insider Threats
In 98% of the assessments conducted for its research, Dtex found employees exposed proprietary company information on the Web – a 20% jump from 2018.

Nearly two-thirds (64%) of insider threats are caused by users who introduce risk due to careless behavior or human error, according to new research from Dtex. This compares to 13% of threats due to compromised credentials and 23% caused by intent on harming the organization.
"That 64% number is huge and something we think companies should focus on," says Rajan Koo, head of Dtex's insider threat research team. "We find that by reducing the number of negligence incidents, companies can cut down on the potential of their employees being compromised."
In related research released this week, Endera reported that companies suffer from at least three workforce-related incidents per week, adding up to 156 incidents per year. And, according to Egress Technologies, more than four out of five companies (83%) have had employees expose customer or business data.
Lock Down Those Links
In 98% of the assessments conducted for its research, Dtex found employees exposed proprietary company information on the Web – a 20% jump from 2018. Typically they send out a document via an insecure link to a colleague or third-party company using file-sharing tools that are unsanctioned by the company, Koo said.
"What happens is people will send a link from their personal Google Docs or Dropbox account, not realizing that the link is not secure," he explains. "In our research, we've found that these documents get indexed on Google and other search engines so the bad guys can easily find them publicly on the Web. We recommend that people lock down any links they send with a user name and password."
The study also found that in 95% of the assessments, employees looked to circumvent company security policies – a notable jump from 60% last year. In many instances, people are using private VPNs and TOR browsers in the hope of shielding their activities, Koo says. While often employees are simply looking to bypass security so they can do their work more efficiently, Dtex has found the use of such tools is often motivated by malicious intent.
Dtex also runs assessments that track whether a person is a flight risk, which Koo defined as a person with a “propensity to leave.” The company found employees engaging in such behavior in 97% of its assessments.
"What we'll do is track people who have spent a lot of time updating their LinkedIn profile or posting their resume and then watch to see if they've made a data transfer to a USB," Koo says. "In almost every organization, people tagged with a high propensity to leave typically take data with them. For each organization we've studied, we find at least one example of this a year."
Koo says security pros have become really good at protecting the perimeter from malware attacks. But as the perimeter erodes with more people working from home, the introduction of cloud-based apps, and the entrance of a younger, digitally fearless workforce who may log onto a corporate network from an insecure outside network, a new crop of user behavior intelligence platforms has surfaced.
These platforms enable companies such as Dtex, Endera, and others to leverage user behavior analytics to more efficiently detect insider threats.
Avivah Litan, a vice president and distinguished analyst at Gartner, says this emerging field of user behavior analytics has been a missing piece in corporate security profiles – until now.
"Dtex and other companies, along with the traditional SIEM vendors, have solutions … that sit on the user's device and can see things that you can't see from the cloud," Litan says. "Companies need to take a look at monitoring users, but do it in a way that respects privacy."
