Companies are more at risk from people within their own companies than from outside hackers – whether losses from this source are deliberate or accidental.
Accidental security incidents by company insiders happen more frequently and have the potential for greater negative impact than malicious insider attacks according to new IDC findings announced today by research sponsor RSA, the security division of EMC.
The IDC white paper also shows a misalignment of security concerns by a majority of C-level executives (CXOs) who give higher priority to protecting against malicious insider attacks over investing to prevent more frequent and potentially more damaging accidental insider security incidents.
The white paper, “Insider Risk Management: A Framework Approach to Internal Security", the potential threat that an organisation is exposed to by internal users who have access to critical systems and confidential information. While aware that users create information security risks within their organisations, external threats often overshadow the importance of protecting against internal risks.
The new research uncovers a misalignment of CXO security concerns with the greater number of internal breaches and the threat posed to a company’s bottom line by accidental security breaches, inappropriate access and misuse of information by its employee base.
Among the global IT decision-makers that responded to the survey, the majority indicated they were unclear on the sources and intentions of internal risk and struggle to quantify the potential financial consequences and workflow impact.
Of the organisations surveyed, 52% characterised their insider threat incidents as predominately accidental, only 19% believed the threats were deliberate, 26% believed they were an equal combination and 3% were unsure. However, when asked to rank their top threats, almost 82% of CXOs were unsure if incidents from contractors and temporary staff were accidental or deliberate.
“Employers view their relationship with employees as one of trust and recognise their people are their biggest asset,” says Chris Christiansen, programme vice-president: security products of IDC. “But the vast nature of an organisation’s infrastructure, coupled with a dispersed, often global employee base and complex internal user mix of employees, consultants, partners and outsourcers make addressing the risks posed by its internal users the biggest security challenge that CXOs currently face: whether the risk is intentional or not, it’s there. It’s real.”
Other insightful results from the white paper highlight the number of insider security incidents from within an organisation. In the previous 12 months, 400 respondents admitted to 6 244 incidents of unintentional data loss, 5 830 malware/spyware attacks from within the enterprise, and 5 794 incidents of risks created by excessive privilege and access control rights. In total, the number of internal security incidents from the respondents came out at 57 485 in the previous 12 months.
The survey results show that almost 40% of organisations plan to increase spending on initiatives to reduce internal security risks over the next 12 months and as few as 6% will decrease spending. These results indicate there is not a single solution to best address internal security risks but rather a need to take a comprehensive risk management approach to better understand the organisation’s risk profile and where to best put controls in place.
“Security is everyone’s job, not just the job of the security team,” says Rob Watson, country manager of RSA. “Internal risks are growing and to remain competitive, CXOs must change the way they defend their business and expand security priorities to address the heightened need for protection from risk – both intentional and accidental – from an insider. CXOs must adopt a holistic strategy to mitigating insider threat that focuses on protecting critical information from misuse, leakage and loss by internal users, whether accidental or deliberate."
Although the increased sophistication of data breaches by determined fraudsters are prevalent, this new data highlights that unintentional data loss and information security controls affects the operational integrity of an organisation to a greater degree than intentional, malicious attacks.
Key research findings include:
* Unintentional versus deliberate risk: Malicious insider threats, such as unauthorised access to confidential data and the spread of malware and spyware from within the enterprise ranked highest among CXO security concerns. However, the insider security threats that caused the largest number of instances (unintentional data loss through employee negligence) and greatest financial impact (out-of-date or excessive privileges and access control rights for users) were accidental.
* Source of threat: In the last year, the greatest source of insider threat came from contractors and temporary employees.
* Financial loss: The average annual financial loss from insider risk was nearly $800,000 in the IT Outsourcing industry.
* Decision-maker uncertainty: While 93% of respondents were responsible for security decisions within their organisations, nearly 82% were unclear on the source of their company’s insider risk and could not accurately pinpoint or quantify the nature of the financial impact.
