Insider threats are costing US businesses millions of dollars a year in lost revenues, new figures have revealed.
More than 78 per cent of respondents to the survey admitted to one or more unreported insider-related security breaches at their company.
Nine out of 10 IT managers surveyed blamed the breaches on a lack of resources, and 81 per cent on poor management. In addition, 89 per cent viewed insider threats as serious, yet only half believe that chief executives have the same perception.
When asked about the top concerns about data integrity the IT managers identified three major threats:
- Missed or failed security patches on critical applications
- Accidental or malicious insider misuse of sensitive or confidential data
- Virus, malware and spyware infections
"The data breaches in the headlines are just the tip of the iceberg of the challenges IT security departments face in relation to insider threats," said Brian T. Contos, chief security officer at ArcSight.
"In addition to the threat of losing control over confidential information, they are also worried about insider activity related to IT sabotage and fraud.
"Addressing insider threats requires a combination of incident prevention, detection and response, and companies have invested in various technologies to address this challenge.
"These solutions are important, but organisations need to have a comprehensive view across the technologies to fully leverage these investments and gain early insight into suspicious activity."
