A staggering 97% of IT leaders say insider breach risk is a significant concern, according to a survey by Egress.
78% think employees have put data at risk accidentally in the past 12 months and 75% think employees have put data at risk intentionally. When asked about the implications of these breaches, 41% say financial damage would be the area of greatest impact.
More than 500 IT leaders and 5000 employees were surveyed across the UK, US and Benelux regions.
The results uncovered serious discrepancies between IT leaders’ perceptions of insider breach risk and causes, and how they are in managing them. It also exposed that employees are still confused about data ownership and responsibility.
Asked what traditional security tools they have in place to mitigate insider breach risk, just half of IT leaders said they are using anti-virus software to combat phishing attacks, 48% are using email encryption and 47% provide secure collaboration tools.
More than half (58%) say employee reporting is more likely than any breach detection system to alert them to an insider data breach.
Egress CEO, Tony Pepper, believes the findings show how IT leaders are resigned to the inevitability of insider breaches and don’t have adequate risk management in place.
“While they acknowledge the sustained risk of insider data breaches, bizarrely IT leaders have not adopted new strategies or technologies to mitigate the risk. Effectively, they are adopting a risk posture in which at least one-third of employees putting data at risk is deemed acceptable.
“The severe penalties for data breaches mean IT leaders must action better risk management strategies, using advanced tools to prevent insider data breaches. They also need better visibility of risk vectors; relying on employees to report incidents is not an acceptable data protection strategy.”
Misdirected and phishing emails top cause of accidental insider data breaches
41% of employees who had accidentally leaked data said they had done so because of a phishing email. 31% said they caused a breach by sending information to the wrong person, for example, by email.
This is underlined by the fact that 45% said they had received an outlook recall message or an email asking them to disregard an email sent in error over the last year.
Tony Pepper adds; “Incidents of people accidentally sharing data with incorrect recipients have existed for as long as they’ve had access to email. As a fundamental communication tool, organizations and security teams have weighed the advantages of efficiency against data security considerations, and frequently compromise on the latter.
“However, we are in an unprecedented time of technological development, where tools built using contextual machine learning can combat common issues, such as misdirected emails, the wrong attachments being added to communications, auto-complete mistakes, and employees not using encryption tools correctly. Organizations need to tune into these advances to truly be able to make email safe.”
Erroneous employee views on data ownership
The survey also showed that employee misconceptions over data ownership have a negative impact on information security. The employee-facing research found 29% of respondents said they or a colleague had intentionally shared data against company policy in the past year.
A worrying 46% said they or a colleague had broken company policy when they took data with them to a new job, while more than a quarter (26%) said they had taken a risk when sharing data because they weren’t provided with the right security tools.
This reckless approach to data protection may be explained by employees’ views on data ownership and responsibility. 41% of the employees surveyed don’t believe that data belongs exclusively to the organization and only 37% recognise that everyone has responsibility for keeping data safe.
Tony Pepper comments: “Employees want to own the data they create and work on, but don’t want the responsibility for keeping it safe. This is a toxic combination for data protection efforts. When you add their propensity to take data with them when they change jobs and willingness to take risks when sharing data, the scale of the challenge faced by security professionals is alarming.”
Directors disrespecting data
The survey also highlighted that the more senior the employee, the more cavalier their attitude towards data breaches. 78% of directors have intentionally shared data against company policy in the past year, compared with just 10% of clerical staff.
Directors are the most likely to take data with them to a new job – 68% of those who had intentionally broken policy had done so when they changed jobs, compared with the overall average of 46%.
