Rise in employees accessing corporate data on personal devices

Lack of awareness about the security risks associated with this.

Smart home devices and their apps represent a major weak link in the corporate cybersecurity chain as the lines between work and home life increasingly blur, according to Trend Micro’s latest study, Head in the Clouds study.

About 36 per cent of Australian workers use personal devices to access corporate data – often via services and applications hosted in the cloud.

These personal smartphones, tablets and laptops may be less secure than corporate equivalents and exposed to vulnerable IoT apps and gadgets on the home network. Close to half (41per cent) of remote workers in Australia surveyed don’t have basic password protection on all personal devices, for example.

Cyberpsychology expert Dr Linda Kaye said, many remote workers use personal devices for accessing corporate data and services suggests that there may be a lack of awareness about the security risks associated with this.

“Tailored cybersecurity training which recognises the diversity of different users and their levels of awareness and attitudes around risks would be beneficial to help mitigate any security threats which may derive from these issues,” she said.

Almost half (49 per cent) of Australian remote workers have IoT devices connected to their home network, eight per cent using lesser-known brands, the study revealed. Many such devices – especially from smaller brands – have well-documented weaknesses such as unpatched firmware vulnerabilities and insecure log-ins.

These could theoretically allow attackers to gain a foothold in the home network, then use unprotected personal devices as a stepping-stone into the corporate networks they’re connected to.

According to Trend Micro there’s an additional risk to enterprise networks post-lockdown if malware infections picked up at home are physically brought into the office via unsecured personal BYOD devices.

The research also revealed that 68 per cent of Australian remote workers connect corporate laptops to the home network. Although these machines are likely to be better protected than personal devices, there is still a risk to corporate data and systems if users can install unapproved applications on these devices to access home IoT devices.

“IoT has empowered simple devices with computing and connectivity, but not necessarily adequate security capabilities”, said Bharat Mistry, principal security strategist at Trend Micro. “They could actually be making hackers’ lives easier by opening backdoors via which they could compromise corporate networks.”

This threat is amplified as an age of mass remote working blurs the lines between private and company devices, putting both personal and business data in the firing line, notes Mistry.

As remote working becomes the norm, organisations must enforce clear policies on acceptable device usage to combat threats caused by smart home networks and personal devices.

Education and awareness training should be encouraged to ensure employees are across best practice security including identifying email threats, malicious files, and malicious URLs.

Trend Micro recommends employers ensure their remote workers are compliant with existing corporate security policies, or, if needed, companies should refine these rules to recognise the threat from BYOD and IoT devices and applications.

Companies should also reappraise the security solutions they offer to employees using home networks to access corporate information. Shifting to a cloud-based security model can alleviate many remote working risks in a highly cost-efficient and effective manner.
