Examining threats to device security in the hybrid workplace

August 13, 2021

As workers break up their time between workplace and off-site work, there’s a higher potential for firm units and information to fall into the improper palms

Over the previous few items of this mini-series on hybrid working, we’ve explored the potential cyber-risks posed by people and their use of cloud and different companies. However what about the important thing piece of know-how that connects these two? Transportable units, comparable to laptops, smartphones, tablets and thumb drives, have all the time represented a serious threat to company IT safety. However in the course of the pandemic these units had been primarily static.

As workplaces reopen and hybrid working turns into a actuality, new working patterns will expose employers to a well-known set of dangers. Nonetheless, this time the sheer variety of workers shuttling forwards and backwards between residence, shared workspaces, buyer places and the workplace means a far higher potential for units and information to finish up within the improper palms.

A brand new method of working

Over 60% of companies are hoping to adopt hybrid working after restrictions ease within the UK. The determine is even higher (64%) across global business leaders. Nonetheless, whereas a mix of workplace and distant work will swimsuit most workers, driving each productiveness and workers wellbeing, there are challenges. On the heart of those lies your most vital asset and doubtlessly the group’s weakest hyperlink within the safety chain: its employees.

What is going to almost certainly emerge when restrictions are eased and the mud settles is way extra fluidity in how and the place workers work. Other than splitting time between workplace and residential, there could possibly be a possibility to work from shared workspaces, whereas visits to buyer and accomplice premises can even start-up once more in earnest. All of this implies one factor: change. That’s a possible concern on the subject of cybersecurity, as people are creatures of routine. Top-of-the-line methods to show safer practices is to encourage automated behaviors, however this turns into a lot tougher when workers now not have a single working sample.

The system safety dangers of hybrid working

On the identical time they’ll be carrying round cell units, connecting on the street and doubtlessly even transporting delicate paper paperwork. On this context, the principle cyber dangers could be outlined as:

  • Misplaced or stolen cell units: If not protected with passcode, sturdy encryption or distant wipe performance, laptops, smartphones and tablets might expose company information and assets. For instance, the UK’s financial watchdog has recorded a whole lot of misplaced or stolen worker units over the previous three years.
  • Misplaced or stolen paper paperwork: Regardless of the recognition of digital applied sciences, conventional paperwork stay a safety threat. In June, a trove of secret UK Ministry of Defence (MoD) docs had been discovered behind a bus stop.
  • Shoulder browsing/eavesdropping: With the arrival of extra journeys to and from the workplace and different places comes a higher threat that people shut by could attempt to eavesdrop on video conversations, or eavesdrop on passwords and different delicate information. Such info, even when solely partially captured, could possibly be used to commit identification fraud or in follow-on social engineering makes an attempt.
  • Insecure Wi-Fi networks: Extra distant working additionally means higher publicity to doubtlessly dangerous Wi-Fi hotspots in public places like prepare stations, airports and occasional outlets. Even when such networks require a password, workers could also be susceptible to digital eavesdropping, malware, session hijacking or man within the center assaults.

How you can mitigate system safety threat

The excellent news is that these threats have been round for years and tried-and-tested insurance policies might help to take the sting out of them. The urgency comes from the truth that, fairly quickly, a majority of workers could also be uncovered, slightly than the comparatively small variety of pre-pandemic distant employees. Right here’s what you are able to do:

Worker coaching and consciousness: Everyone knows that efficient staff training programs might help to cut back phishing threat. Nicely, the identical processes could be tailored so as to add consciousness elevating for workers on the potential threats talked about above, together with matters comparable to password administration, social engineering and secure internet utilization. Gamification techniques are more and more well-liked as they’ve been confirmed to speed up the training course of, enhance information retention and impact lasting habits adjustments.

Entry management insurance policies: Person authentication is a key a part of any company safety technique, particularly when managing giant numbers of distant customers. Insurance policies needs to be tailor-made to the group’s threat urge for food, however finest practices often embrace sturdy, distinctive passwords, saved in a password supervisor, and/or multi-factor authentication (MFA). The latter implies that, even when a digital eavesdropper or shoulder surfer captures your password or one-time credential, the account will stay safe.

System safety: It goes with out saying that the units themselves needs to be protected and managed by IT. Robust disk encryption, biometric authentication, distant lock and information wipe, passcode safety with automated lockout, endpoint safety, common patching/automated updates and cloud back-up are all vital parts. The NSA has a helpful guidelines for cell units here.

Zero Belief: This increasingly popular security model was designed for a world by which customers can entry company assets securely from wherever, on any system. The secret is steady risk-based authentication of consumer and system, community segmentation and different safety controls. Organizations ought to assume breach, implement a coverage of least privilege, and deal with all networks as untrusted.

Ultimate ideas

The shift to hybrid working gained’t be straightforward, and there could also be a number of company casualties within the early days. However with a stable set of safety insurance policies enforced by trusted applied sciences and suppliers, employers have a lot to realize from ‘setting their workforce free’.
