The Insider Threat 2018 Report found that 90% of organisations surveyed felt vulnerable to insider attacks. The main causes included too many users with unnecessary access privileges (37%), the growing number of devices with access to sensitive information (36%) and the increasing complexity of information technology (35%).
What is an insider threat?
We usually associate insider threats with disgruntled employees who intend to harm their employer, but this is not always the case. Insiders threats also include negligent employees who unintentionally compromise data, whether it be from falling victim to a phishing attack, inadvertently disclosing confidential information, or by other means.
Other key findings from the report
- The insider threats organisations were most concerned about are accidental/unintentional insiders (51%) and malicious/deliberate insiders (47%).
- The biggest enabler of accidental insider threats was phishing attempts (67%), followed by weak passwords (56%), unlocked devices (44%) and bad password-sharing practices (44%).
- 53% admitted they had suffered an insider attack in the past year, and 27% said that insider attacks have increased in frequency.
- 66% considered insider attacks (malicious or accidental) more likely than external attacks.
- Lack of training and expertise (52%) was cited as the biggest barrier to improved insider threat management.
- 82% have offered training to employees about how to reduce insider security risks, but 13% haven’t.

It’s important to remember that any organisation can be affected at any time. Internal threats should be addressed in the same way external attacks are. Here are some actions that you can take:
- Implement deterrence, detection and monitoring measures.
- Review employees’ access control levels regularly.
- Train your staff on information security and cyber security best practices.
