9 Cloud Data Security Challenges & How To Overcome Them

In today's digital landscape, protecting sensitive information is more critical than ever. With the increasing adoption of cloud services, organizations are storing more and more data in the cloud. While the cloud offers many benefits such as scalability, accessibility, and cost-effectiveness, it also presents a unique set of security challenges. Cloud data security is crucial to protect sensitive information, maintain data integrity, and comply with various regulations. Cloud breaches can lead to sensitive information being exposed, financial losses, and damage to an organization's reputation. With the burgeoning use of cloud-based systems, organizations must ensure that their data is protected and that they are compliant with industry regulations.

In the wake of the security risks, organizations must prioritize data security in their cloud infrastructure and implement necessary measures such as encryption, access controls, and incident response plans to protect their data from potential threats and breaches. In this article, we look at the top 9 cloud data security challenges that organizations typically face, discuss their potential costs, and the measures to overcome the risks.

9 cloud data security challenges that are relevant today

Before delving into the challenges, it is important to get a handle on the landscape of cloud data security and why these challenges can have such a pronounced impact on businesses. Cost is the main component that we need to understand in this regard.

Issues with cloud data security that result in breaches or theft of sensitive data can come with many tangible and intangible costs. First, companies that fail to secure compliance with the relevant data security laws and regulations can be imposed heavy fines, a financial burden that their financial reserves might not be equipped to handle in the long term. Apart from fines and sanctions, there is also a chance that data breaches would be accounted for by a large loss of customers, coupled with an equally large loss of revenue.

Finally, the long-term cost companies must worry about is the cost of loss of reputation and reliability. This can affect customer acquisition in the long-term and dramatically alter the prospects of a business. Many companies have been forced to scale down significantly or shut down completely because of a data breach.

While cloud data security challenges might be a problem for all industries, those that are routinely dealing with personal and sensitive information, like healthcare, medicine, aviation, and insurance seem more likely to feel the effects at a larger scale.

Lack of visibility and control

Lack of visibility and control is one of the most critical challenges that companies face as they move to the cloud. Without this ability organizations will struggle to maintain security and compliance and have a tough time identifying and remedying potential threats.  

Data visibility and control involves full knowledge of what data is stored, where it is stored, who can access the data, and what data security measures can be best employed to mitigate potential risk. Various means of visibility and control, like data classification, have been seen to better equip businesses to deal with data loss or theft quickly and easily, as borne out by the findings of the 2021 Cloud Data Security Report by Netwrix. Organizations can bring better visibility and control into their enterprise data by deploying the following solutions:

• Implement a cloud security posture management (CSPM) solution to gain visibility into cloud infrastructure and automate security controls.
• Use a cloud access security broker (CASB) to monitor and control access to cloud applications and data.
• Use security information and event management (SIEM) solutions to collect and analyze security data from the cloud.
• Establish a cloud security governance framework to ensure that security and compliance policies are being followed.
• Regularly review and update cloud security and compliance policies and procedures.
• Educate employees on cloud security best practices and the importance of maintaining visibility and control.

Cloud data breaches

Cloud data breaches are an increasingly common concern as more organizations move their data to the cloud. These breaches occur when unauthorized individuals gain access to sensitive information, resulting in a loss of confidentiality, integrity, and availability of the data. The breaches can happen due to numerous factors such as weak passwords, misconfigured cloud services, and phishing attacks.

Data breaches are particularly damaging to the reputation of a business and its finances. In fact, according to an IBM Security report discussing the cost of data breaches in 2022, 83% of organizations under their survey have had at least one data breach, with the average total cost of a data breach sitting at $4.35 million – a cause for concern. Organizations can address cloud data breaches by deploying the following solutions:

• Use multi-factor authentication to protect against unauthorized access to cloud data.
• Use encryption to protect data while in transit and while at rest.
• Regularly review and update cloud security and compliance policies and procedures.
• Use security information and event management (SIEM) solutions to detect and respond to security incidents.
• Conduct regular security assessments to identify vulnerabilities.
• Educate employees on correctly identifying, avoiding, and mitigating phishing attacks.
