ドイツでの注目すべき事例 :ハイブリッドワークへの移行により新たな脅威のリスクが高まる
As German organizations plan their long-term hybrid and remote work models, embracing this new world of work opens the door to new and unmanaged cyber risk. 攻撃者はチャンスに付け込んでいますTo address this, we need to change the way we're thinking about risk.
While the pandemic-driven work-from-home obligation in Germany has been revoked, many organizations still plan to continue long-term hybrid and remote work models. At the beginning of 2020, just 22% of German organizations had employees working remotely. Today, that has risen to 82%, with 65% planning to make this adoption permanent in the next 1-2 years. But, by their own admission, only 58% of German organizations feel they are prepared to support new workforce strategies from a security standpoint.
The self-reported data is drawn from a commissioned study of more than 1,300 security leaders, business executives and remote employees worldwide, including 156 respondents in Germany. 「境界を超える:The Future of Cybersecurity in the New World of Work, was conducted by Forrester Consulting on behalf of Tenable in April 2021.
Cloud adoption enables hybrid working model
Historically, German organizations have been reluctant, and some even resistant, to embrace cloud adoption. The pandemic has completely changed that. To facilitate a remote workforce, cloud adoption has accelerated, shattering the boundaries of the corporate network and introducing exponential risk.
Seventy-three percent of German organizations said they have moved business-critical functions to the cloud, including accounting and finance (51%) and human resources (48%). When asked if this exposed the organization to increased cyber risk, 76% of security and business leaders believed it did.
Business-critical systems weren't the only ones shifted to the cloud. More than a third (35%) of German organizations also moved non-critical functions to the cloud in response to the pandemic, despite 57% of security leaders believing this increased their exposure to risk.
攻撃者はチャンスに付け込んでいます
With little attention given to security during this massive shift, attackers have taken advantage. Ninety-three percent of German organizations experienced a business-impacting cyberattack* in the last 12 months, with 57% falling victim to five or more.
When looking at the focus of these attacks:
- 78% resulted from vulnerabilities in systems and/or applications put in place in response to the pandemic
- 66% targeted remote workers or those working from home
- 61% involved cloud assets
- 61% involved an unmanaged personal device used in a remote work environment
The impact to organizations is far from trivial as 44% suffered a ransomware attack and 35% experienced a data breach.
We need to change the way we're thinking about risk
As organizations adjust to the new world of work — one that combines in-office and work-from-home models — CISOs and infosec leaders must reevaluate their approach to maintaining security in highly dynamic and disparate environments. This includes realigning themselves to the business in order to effectively reduce risk.
Security teams need visibility of their entire threat landscape, with the intelligence to predict which cyberthreats will have the greatest business impact on the organization. In tandem, controls are needed to address the risks introduced by the new world of work.
Improving the way Active Directory is configured and managed is crucial to disrupting attack paths. Organizations need to implement adaptive user risk profiles in order to continuously monitor and verify every attempt to access corporate data based on set criteria — who is requesting access, where are they connecting from and the hygiene of the device being used. If the criteria aren't met, the request is declined.
If cybersecurity strategies fail to keep pace with business changes, today's risk could become tomorrow's reality.
