No. 15 Major cause of security breaches in European organisations

Where do you believe these breaches mainly came from?

Base: Establishments that were affected by security breaches in the last 12 months, weighted percentages, multi-response
Question: D3

Computer hackers are considered the major cause of security breaches by 40% of European organisations, closely followed by insiders (e.g. members of staff). Customers, suppliers and former employees, instead, are considered less relevant. The fact that internal users are believed to be a source for security breaches almost as often as computer hackers (and the viruses they create) is a clear sign that IT security measures can deliver the expected protection if all authorised users are aware of their pivotal “security” link of an organisation. Consequently, employees’ education and training in information security activities are fundamental.
