Increased cloud complexity needs stronger cybersecurity

A Thales report, conducted by 451 Research, reveals that 45% of businesses have experienced a cloud-based data breach or failed audit in the past 12 months, up 5% from the previous year, raising even greater concerns regarding to protecting sensitive data from cybercriminals.

multicloud environments complexity

Globally, cloud adoption and notably multicloud adoption, remains on the rise. In 2021, organizations worldwide were using an average amount of 110 software as a service (SaaS) applications, compared with just eight in 2015, showcasing a startlingly rapid increase.

There has been a notable expansion in the use of multiple IaaS providers, with 72% of businesses using multiple IaaS providers, up from 57% the year before. The use of multiple providers has almost doubled in the last year, with 20% of respondents reporting using three or more providers.

Despite their increasing prevalence and use, businesses share common concerns about the increasing complexity of cloud services with 51% of IT professionals agreeing that it is more complex to manage privacy and data protection in the cloud. Additionally, the journey to the cloud is also becoming more complex, with the percentage of respondents reporting that they’re expecting to lift and shift, the simplest of migration tactics, dropping from 55% in 2021 to 24% currently.

Security challenges of multicloud complexity

With increasing complexity of multicloud environments comes an even greater need for robust cybersecurity. When asked what percentage of their sensitive data is stored in the cloud, 66% said between 21-60%. However, only 25% said they could fully classify all data.

Additionally, 32% of respondents admitted to having to issue a breach notification to a government agency, customer, partner or employees. This should be a cause for concern among enterprises with sensitive data, particularly in highly regulated industries.

Cyber-attacks also present an ongoing risk to cloud applications and data. Respondents reported an increasing prevalence of attacks, with 26% citing an increase in malware, 25% in ransomware and 19% reporting seeing an increase in phishing/ whaling.

Protecting sensitive data

When it comes to securing data in multicloud environments, IT professionals view encryption as a critical security control. The majority of respondents cited encryption (59%) and key management (52%) as the security technologies they currently use to protect sensitive data in the cloud.

However, when asked what percentage of their data in the cloud is encrypted, 11% of respondents said between 81-100% is encrypted. Additionally, key management platform sprawl may be an issue for enterprises. Only 10% of respondents use one to two platforms, 90% use three or more, and 17% admitted using eight or more platforms.

Encryption should be a priority area for enterprises to focus on when it comes to securing data in the cloud. In fact, 40% of respondents stated that they were able to avoid the breach notification process because the stolen or leaked data was encrypted or tokenised, showcasing the tangible value of encryption platforms.

Additionally, it is encouraging to see signs enterprises embrace zero trust and investing accordingly. 29% of respondents said they are already executing a zero trust strategy, 27% said they are evaluating and planning one and, 23% said they are considering it. This is a positive result, but there is certainly still room to grow.

Sebastien Cano, SVP for Cloud Protection and Licensing activities at Thales said: “The complexity of managing multicloud environments cannot be overstated. Additionally, the growing importance of data sovereignty is increasingly raising questions for CISOs and Data Protection Officers when considering their cloud strategy, governance, and risk management. The challenge is not only where the sensitive data resides geographically, but even who has access to sensitive data inside the organization.

“There are various solutions such as encryption and key management. Last but not least, continuing to embrace a zero trust strategy will be essential in securing these complex environments, helping to ensure organizations can support their data and manage future challenges.”
