The rise in data loss and theft, according to the survey, is due in large part to compromises in insider accounts that are exacerbated by far wider employee and third-party access to sensitive information than is necessary, and by the continued failure to monitor access and activity around email and file systems – where most confidential and sensitive data moves and lives.
The survey report, “Closing Security Gaps to Protect Corporate Data: A Study of U.S. and European Organisations,” resulted from interviews conducted in April and May, 2016, with 3,027 employees in the United States, United Kingdom, France, and Germany. Respondents included 1,371 end users and 1,656 IT and IT security professionals, in organisations ranging in size from dozens to tens of thousands of employees from a variety of industries including financial services, public sector, health care and life sciences, retail, industrial, and technology and software. Among the key findings:
- Seventy-six percent of IT practitioners say their organisation experienced the loss or theft of company data over the past two years. This is a significant increase from 67 percent of IT respondents who gave the same response in the 2014 study conducted by Ponemon for Varonis.
- IT respondents say insider negligence is more than twice as likely to cause the compromise of insider accounts as any other culprits, including external attackers, malicious employees or contractors.
- Seventy-eight percent of IT people are very concerned about ransomware, a type of malicious software that that blocks access to files until a sum of money is paid. Fifteen percent of organisations have experienced ransomware and barely half of those detected the attack in the first 24 hours.
- Eighty-eight percent of end users say their jobs require them to access and use proprietary information such as customer data, contact lists, employee records, financial reports, confidential business documents, or other sensitive information assets. This is sharply higher than the 76 percent recorded in the 2014 study.
- Sixty-two percent of end users say they have access to company data they probably shouldn’t see.
- Only 29 percent of IT respondents report that their organisations enforce a strict least-privilege model to ensure insiders have access to company data on a need-to-know basis.
- Only 25 percent of organisations monitor all employee and third-party email and file activity, while 38 percent do not monitor any file and email activity.
- Thirty-five percent of organisations have no searchable records of file system activity, leaving them unable to determine, among other things, which files have been encrypted by ransomware.
Dr. Larry Ponemon, Chairman and Founder of Ponemon Institute, a leading research center dedicated to privacy, data protection and information security policy, observed, "Despite all the technology available and the spike in highly publicised attacks, data breaches continue to rise. The most valuable data featured in most breaches is unstructured data such as emails and documents. When emails and files are surfaced, they tend to cause scandal, forcing the breach to have a lasting effect on the company’s reputation. This survey raises key points as to why hackers are able to maximise impact – too many employees have too much access, beyond what they need to do their jobs. On top of this, when employees access valuable data and their activity is not tracked or audited, it becomes far too easy for an external hacker or a rogue insider to get away unnoticed.”
Yaki Faitelson, Co-Founder and CEO of Varonis, said, “Right now we’re in a technology arms race with hackers and insider threats. Unnecessarily excessive internal access combined with a lack of monitoring and auditing sets organisations up for disaster. Sony Pictures, the Panama Papers and the recent Democratic National Committee intrusions all concerned the theft of files and emails that were not protected well enough from insider threats or outside attackers that compromised insider credentials, causing major damage to those organisations and their reputations. These new findings, alongside the fallout from those breaches, should keep executives awake at night. What will be the straw that makes businesses focus their efforts on protecting their precious information assets? Varonis is helping thousands of organisations around the world address these challenges, prepare for and stop ransomware and other malicious threats that get inside and impersonate insiders.”
