Cloud data breaches increase in past year, but only 45% is encrypted – Thales

by Anthony Weaver

Cloud assets the biggest targets for cyberattacks, as data breaches

 ·       39% of businesses experienced a data breach in their cloud
environment last year, an increase of 4points from the previous year

 ·       More sensitive data moving to the cloud with 75% of businesses
saying more than 40% of data stored in the cloud is sensitive, up 26%
from last year

 ·       Despite dramatic increase in sensitive data stored in the
cloud, on average only 45% of this sensitive data is encrypted


Thales [2] today announced the release of the 2023 Thales Cloud Security
Study [1], its annual assessment on the latest cloud security threats,
trends and emerging risks based on a survey of nearly 3,000 IT and
security professionals across 18 countries.

This year’s study found that more than a third (39%) of businesses have
experienced a data breach in their cloud environment last year, an
increase on the 35% reported in 2022. In addition, human error was
reported as the leading cause of cloud data breaches by over half (55%)
of those surveyed.

This comes as businesses reported a dramatic increase in the level of
sensitive data stored in the cloud. Three quarters (75%) of businesses
said that more than 40% of data stored in the cloud is classified as
sensitive, compared to 49% of businesses this time last year.

More than a third (38%) ranked Software as a Service (SaaS) applications
as the leading target for hackers, closely followed by cloud-based
storage (36%).

Lack of Encryption and Key Control Causes Cloud Data Concerns

Despite the reported increase in sensitive data in the cloud, the study
found low levels of encryption being used. Only a fifth (22%) of IT
professionals reported that more than 60% of their sensitive data in the
cloud is encrypted. According to the findings, on average, only 45% of
cloud data is currently encrypted.

The study also found a lack of control over encryption keys by
businesses, with only 14% of those surveyed stating that they controlled
all of the keys to their encrypted data in their cloud environments. In
addition, almost two thirds (62%) say they have five or more key
management systems – creating increased complexity when securing
sensitive data.

Multicloud Causing Operational Complexity

The adoption of multicloud continues to surge, with more than three
quarters (79%) of organisations having more than one cloud provider.

Notably, it’s not just infrastructure that is experiencing this growth.
The use of SaaS apps is also on the rise significantly. In 2021, 16% of
respondents reported their enterprises utilising 51-100 different SaaS
applications, while in 2023 this percentage increased to 22%.

Despite the expansion of cloud usage, a significant challenge remains.
More than half (55%) expressed that managing data in the cloud is more
complex than in on-premises environments – up from 46% compared to the
previous year. Digital sovereignty is also front of mind for
respondents. Eighty three percent expressed concerns over data
sovereignty, and 55% agreed that data privacy and compliance in the
cloud has become more difficult.

Pathways to Better Cloud Security

Identity and access management (IAM) is a crucial measure in mitigating
data breaches, emphasising the significance of strong security
practices. Encouragingly, the adoption of robust multi-factor
authentication (MFA) has risen to 65%, indicating progress in fortifying
access controls.

Surprisingly, only 41% of organisations have implemented zero trust
controls in their cloud infrastructure, and an even smaller percentage
(38%) utilises such controls within their cloud networks. These
statistics highlight the need for greater emphasis on adopting
comprehensive security measures to effectively safeguard sensitive data
and enhance overall cybersecurity resilience.

_”The study shows that organisations are operating in a dynamic
multicloud landscape, demanding seamless and efficient access to
on-demand IT infrastructure and services,”_ stated Sebastien Cano,
Senior Vice President for Cloud Protection and Licensing activities at

_”Treating cloud environments as an extension of existing infrastructure
while maintaining exclusive control and security of data, especially
sensitive data, is key to cloud security. Customer control of encryption
keys is essential as it allows organisations to leverage the
scalability, cost efficiency, and accessibility benefits of the cloud
while ensuring the utmost integrity and confidentiality of their
valuable information.”_

About the 2023 Thales Cloud Security Report

The 2023 Thales Cloud Security Report was based on a global S&P Global
Market Intelligence survey commissioned by Thales of almost 3000
executives with responsibility for or influence over IT and data
security. Respondents were from 18 countries: Australia, Brazil, Canada,
France, Germany, Hong Kong, India, Italy, Japan, Mexico, Netherlands,
New Zealand, Singapore, South Korea, Sweden, the United Arab Emirates,
the United Kingdom, and the United States. Organisations represented a
range of industries, with a primary emphasis on healthcare, financial
services, retail, technology, and federal government. Job titles ranged
from C-level executives including CEO, CFO, Chief Data Officer, CISO,
Chief Data Scientist, and Chief Risk Officer, to SVP/VP, IT
Administrator, Security Analyst, Security Engineer, and Systems
Administrator. Respondents represented a broad range of organisational
sizes, with the majority ranging from 500 to 10,000 employees. The
survey was conducted in November and December 2022.
