Cybercriminals continue to focus their efforts on what is widely considered to be the weakest link in the security chain: the user. Consequently, developing a comprehensive understanding of user behavior and the implications thereof becomes paramount to corporate security strategy.

In analysing user behavior across 10 million users, 1 billion files, and over 91,000 cloud applications, CloudLock surfaced surprising trends.

In this report, Cloudlock examine cloud cybersecurity trends across three primary dimensions: users, collaboration, and applications. The Pareto Principle, the “80/20” rule, holds true across all three dimensions, revealing a truth with surprising implications for security professionals.

Key Findings

Users: 1% of users create 75% of cloud cybersecurity risk, signalling abnormal user behavior whether unintentional or malicious.

  • Collaboration: While organizations on average collaborate with 865 external parties, just 25 of these account for 75% of cloud-based sharing per organization. Unexpectedly, 70% of sharing occurs with non-corporate email addresses security teams have little control over.
  • Apps: 1% of users represent 62% of all app installs in the cloud – a high concentration. Without security awareness, this small user base introduces a high volume of risk. Additionally, 52,000 installs of applications are conducted by highly privileged users – a number that should be zero given privileged accounts are highly coveted by malicious cybercriminals.

4 Actionable Takeaways for a more secure cloud environment

The findings of this report show disproportionate cloud cybersecurity risk across users, collaboration, and applications. Consider the four following risk remediation strategies.

1. Focus on the User Behavior

Focusing on the riskiest subset of users, security professionals can efficiently and dramatically reduce risk. Any abnormal behavior by data-dense and risky users should be prioritized providing the security team with valuable direction on what truly requires attention and resolution immediately.

2. Focus Security on Organizations You Collaborate With Most

Given that, on average, 75% of inter-organizational sharing is with 25 external organizations, focus on the frequent collaborative organizations to eliminate the bulk of risk, then address the long tail of remaining organizations.

3. Take Application Security beyond Discovery

Discovering third-party applications that reside on the network is only the tip of the iceberg. Elevate your security game beyond app discovery through enforcement capabilities, policy-driven app control, and end-user education. If users are blocked, they will find a way around.

4. Correlate Insights Across Cloud Environments

With multi-cloud intelligence, security teams can correlate security events across platforms, preventing cybercriminal exploits from slipping through the cracks. Consider an individual logging into Salesforce in San Francisco and ServiceNow in Kuala Lumpur using the same credentials simultaneously, indicating account compromise. Avoid point security solutions in favor of platforms offering multi-cloud insights across not only SaaS applications, but also laaS, PaaS, and IDaaS environments.
