Insider threats are another common security challenge that organizations face when using cloud services.

Malicious insiders can abuse their access to cloud resources to steal sensitive data or disrupt operations.

Example: In 2018, a former Tesla employee named Guangzhi Cao was accused of hacking into Tesla’s Amazon Web Services (AWS) servers and stealing confidential company data, including the source code for Tesla’s Autopilot driver-assistance system.

Cao had worked as a software engineer for Tesla, but left the company in January 2018 to work for a Chinese self-driving car startup called Xiaopeng Motors.

According to the criminal complaint filed by the FBI, Cao had used his former Tesla employee credentials to access the company’s AWS servers and download more than 300,000 files related to Tesla’s Autopilot source code and other confidential company information.

Cao’s actions were discovered after Tesla launched an investigation and found evidence of the theft.

4. Misconfigurations

Misconfigurations are another common security challenge that organizations face when using cloud services.

Misconfigurations can lead to unintended exposure of sensitive data, making it accessible to unauthorized parties.

Example: In 2020, a misconfigured AWS bucket exposed personal data of over 100 million Android users, including call logs, phone numbers, and text messages.

5. Denial of Service (DoS) attacks

Denial of Service (DoS) attacks are another common security challenge that organizations face when using cloud services.

Attackers can flood cloud resources with traffic, making them unavailable to legitimate users.

The attack used IoT devices, including cameras and routers, to generate traffic to overload cloud servers.

6. Compliance and regulatory issues

Organizations may face compliance and regulatory challenges when using cloud services, especially when it comes to storing and managing sensitive data.

Compliance regulations such as GDPR and HIPAA require organizations to maintain certain data protection standards, which can be difficult to achieve in a cloud environment.

Example: In 2018, Uber was fined $148 million for failing to disclose a data breach that occurred in 2016.

The breach compromised the personal information of 57 million customers and drivers, and Uber’s handling of the incident violated GDPR.

7. Third-party risks

Organizations may also face security challenges due to third-party vendors or services used in conjunction with cloud services.

Third-party vendors may not have the same security standards as the organization, creating potential security gaps.

Example: In 2019, a data breach at a third-party vendor of American Medical Collection Agency (AMCA) compromised personal and medical information of millions of patients.

The breach affected several organizations that used AMCA’s services, highlighting the risks of third-party vendors.

8. Data privacy and confidentiality

Organizations may face challenges in maintaining data privacy and confidentiality when using cloud services.

Sensitive data may be inadvertently exposed due to misconfigurations or weak access controls, leading to privacy violations.

Example: In 2017, an AWS misconfiguration by a third-party vendor exposed the personal information of millions of Verizon customers, including names, addresses, and account details.

9. Cloud service provider vulnerabilities

Organizations may face security challenges due to vulnerabilities in the cloud service provider’s infrastructure.

These vulnerabilities can be exploited by attackers to gain unauthorized access to the organization’s data or infrastructure.

Example: In 2018, Google Cloud Platform suffered a vulnerability that allowed attackers to access data from other customers using the same cloud platform.

The vulnerability affected several organizations, highlighting the risks of shared infrastructure.

These are some of the most common security challenges faced by organizations when using cloud services.

As the examples illustrate, these challenges can have severe consequences, ranging from data breaches to disrupted operations.
