Why cloud security is the key to unlocking value from hybrid working

August 6, 2021

How can firms and workers who begin to adapt to hybrid working practices defend themselves towards cloud safety threats?

When authorities lockdowns pressured employees to remain dwelling en masse for a lot of 2020, one know-how was there to choose up the items. With out the three predominant cloud computing fashions, software-, platform- and infrastructure-as-a-service (SaaS, PaaS and IaaS, respectively), it’s unlikely many organizations would have survived these darkish days. However as information and customers migrated to the cloud in huge numbers, those self same platforms shortly turned a serious goal for assault.

In line with one study, 90 % of world CXOs reported a rise in cyberattacks within the early days of the pandemic, and much more (98 %) noticed a rise in safety challenges within the first two months of the shift to remote work. A lot of this can undoubtedly have been cloud-related. The trick now {that a} new hybrid office is rising will likely be to handle these challenges extra successfully, in a method that reduces cyber-risk with out impacting person productiveness.

How cloud saved the day

The headline figures have been astonishing. For instance, video conferencing start-up Zoom has stated that it went from 10 million to over 200 million lively customers between December 2019 and March 2020. Microsoft claimed its rival Groups platform had over 200 million assembly contributors in a single day in April, amounting to what CEO Satya Nadella described as “two years’ value of digital transformation in two months.”

Third-party analysis backs-up these daring claims. A Snow Software study in June 2020 revealed 52 % of world organizations had elevated their reliance on cloud-based video conferencing platforms, whereas three-quarters (76 %) stated they’d spent extra on cloud infrastructure from the likes of Microsoft Azure, Google and Amazon Net Providers. The adoption of cloud computing will solely proceed to extend, with Gartner predicting lately that spending on public cloud companies will develop 18.4 % in 2021.

It’s simple to see why. The power to log-on from anyplace on the earth and entry company information and functions, host conferences and collaborate with colleagues was completely invaluable to customers in lockdown. Bigger scale IaaS deployments, in the meantime, helped to help new customer-facing web sites, functions and go-to-market methods to have interaction prospects on-line. From hosted e mail and CRM to revolutionary new B2C companies, the cloud in all its guises was there to maintain organizations operational after they wanted it most.

Why is cloud a distant working threat?

But safety has all the time been the elephant within the room on the subject of cloud. With SaaS, it successfully expands the normal company perimeter, placing information within the palms of a third-party supplier and out of the management of IT.


The cloud entails higher complexity, which may create safety gaps – particularly if organizations are working a number of hybrid clouds alongside on-premises servers, a few of which can should be accessed via VPN. That is difficult for IT to run securely and it’s actually difficult for workers to make use of securely. On common, 92 percent of organizations have a multi-cloud strategy at this time and 82 % have a hybrid cloud technique.

The cloud expands the company assault floor considerably for risk actors – offering extra to intention at within the type of misconfigured accounts and techniques, weak passwords and vulnerabilities. Add to this the usage of insecure dwelling networks and units and poorly skilled, distracted customers and you’ve got an ideal storm for distant working cyber-risk.

Some key cloud safety challenges

These threats aren’t theoretical. Over the course of the pandemic we’ve seen first-hand how the cloud has been focused by risk actors, and unwittingly uncovered by builders and customers. Listed below are a few of the most notable examples:

Phishing: As workers are handed the keys to extra company SaaS accounts, their log-ins grow to be a higher phishing threat. Within the early days, many of those phishing assaults have been focused around COVID-specific lures. Google claimed in April 2020 to be blocking 18 million malicious and phishing emails associated to the pandemic every day. Credentials may very well be used to unlock enterprise functions and in brute power assaults to strive towards different accounts. Over half one million Zoom accounts were found up for sale on the darkish net because of credential stuffing.

Misconfiguration: This might take two types. The primary includes merely failing to modify on the proper safety and privateness settings in apps reminiscent of video conferencing, probably exposing your chats to eavesdroppers. That is the danger that gave rise to Zoombombing, though Zoom has since improved built-in safety an amazing deal and switched a lot of an important settings on by default.

A second, maybe extra harmful kind of misconfiguration, returns us to the difficulty of multi- and hybrid cloud complexity. IT groups often leave storage buckets open to all-comers by failing to use the proper insurance policies to accounts. The dangerous information is that hackers are more and more scanning for these uncovered databases.

Vulnerabilities: People are fallible, and so is their code. In the course of the pandemic, main zero-days have been found in Zoom and different SaaS apps which might have enabled attackers to take distant management of customers’ units. In-house net functions hosted within the cloud are additionally in danger. According to one estimate, fundamental net software assaults have been liable for over 20% of breaches final 12 months.

enhance cloud safety for hybrid employees

The excellent news is that safety consultants like ESET have been selling finest practices in cloud safety for years. Whereas there’s no silver bullet, the next will assist to mitigate cyber-risk as your workers begin to adapt to new hybrid working practices:

  • Classify enterprise information flowing by means of the cloud and put in place acceptable controls
  • Perceive the shared responsibility model for cloud safety
  • Sturdy encryption for information residing within the cloud at relaxation and in transit
  • Sturdy passwords (use a password supervisor)
  • Multi-factor authentication (MFA) for all accounts
  • Limit entry to delicate accounts with a policy of least privilege
  • Think about using a cloud entry safety dealer to coordinate authentication and encryption
  • Configure SaaS accounts correctly based on your threat urge for food (safety and privateness settings)
  • Use a cloud safety posture administration (CSPM) software to flag IaaS misconfigurations
  • Common employees safety coaching on the way to spot phishing
  • Immediate risk-based patching of all cloud servers and software program
  • Take into account Zero Belief strategy to scale back the influence of cloud breaches

Cloud computing will more and more be the norm moderately than the exception for enterprise IT. Get forward of the sport now on safety and your group can drive main enterprise advantages whereas managing cyber-risk to acceptable ranges.
