Top insider threats revealed

All organisations are vulnerable to insider abuse, errors and malicious attacks. These can affect reputation, operations and profitability, and expose data, harm the organisation and deliver valuable intellectual property into competitors’ hands.

Insiders can be current or former employees, contractors, or other business partners who have been granted authorised access to networks, systems or data. All of them can bypass security measures through legitimate means.

New report highlights the state of insider threats

According to the 2016 Insider Threat Report, organisations are most concerned about the following insider threats:

  • Inadvertent data breach/leak (71%), e.g. a careless user causing an accidental breach.
  • Negligent data breach (68%), e.g. a user wilfully ignoring policies, but not malicious.
  • Malicious data breach (61%), e.g. a user wilfully causing harm.

Privileged IT users, such as administrators who have access to sensitive information, pose the biggest insider threat (60%), closely followed by contractors and consultants (57%).

The report also highlighted the IT assets that are most vulnerable to insider attacks:

  • Databases (57%)
  • File servers (55%)
  • Mobile devices (44%)

Along with the data most vulnerable to insider attacks:

  • Customer data (63%)
  • Sensitive financial data (55%)
  • Intellectual property (54%)

Why are insider threats increasing?

The report highlighted the main reasons why insider threats are rising:

  • Lack of employee training/awareness (62%)
  • Insufficient data protection strategies or solutions (57%)
  • Increasing number of devices with access to sensitive data (54%)

What can you do to prevent an insider attack?

74% of organisations feel vulnerable to insider threats – a 7% increase on 2015’s survey results – and only 42% of organisations feel they have the appropriate controls in place to prevent an insider attack.

Alan Calder, founder and executive chairman of IT Governance, says: “Insider threat is a big part of the information security challenge that organisations face. In most cases, mistakes will be made unintentionally, but the underlying message is that in order to prevent these from happening, companies must educate staff, enforce effective policies and procedures, and manage access control.

ISO 27001 should be the default standard that organisations turn to when addressing insider threat and other issues, and adopting an integrated approach to people, process and technology.”
