Data Loss and Leakage

Storing sensitive data in the cloud exposes it to various security risks, particularly if employees use unauthorised applications. Data loss or leakage can result in severe financial penalties and reputational damage[1].

GDPR Compliance

Under the UK GDPR, businesses must ensure the protection of personal data across all storage points. Meeting these standards can be challenging, especially in a cloud environment with multiple users and access points[4].

Shadow IT

Employees may use unapproved applications that bypass IT security protocols, known as “shadow IT.” These apps create security gaps and pose a significant risk to data security[1].

Data Visibility and Control

Knowing where your data is stored, who has access, and how it’s used is vital. However, in cloud environments, maintaining this level of visibility can be difficult without the right tools[1].

Leveraging Cloud Access Security Brokers (CASBs)

One of the most effective ways to address these challenges is by implementing Cloud Access Security Brokers (CASBs).

What is a CASB?

A CASB is a security layer that sits between your on-premises infrastructure and your cloud services. It acts as an intermediary that monitors and enforces security policies on data and apps in the cloud, bringing control and visibility to your cloud environments[1].

Key Functions of CASBs

Data Loss Prevention (DLP): CASBs offer advanced DLP features, monitoring data in transit and at rest within the cloud environment. They can detect sensitive information and apply encryption, ensuring only authorised users can access critical data[1].
Compliance with UK Data Protection Act and GDPR: CASBs help businesses meet GDPR and UK Data Protection Act standards by managing and reporting on data processing activities. They log and track every access attempt, providing a record for compliance and investigation purposes[1].
Shadow IT Detection and Control: CASBs detect unapproved apps, providing visibility into the applications employees use and assessing their security risk. This helps businesses regain control over their cloud environment and enforce appropriate security policies[1].

Implementing Robust Backup and Recovery Protocols

Backup and recovery protocols are crucial for ensuring data integrity and business continuity.

Why Backup Protocols are Key

Regular data backups ensure that the most recent information is preserved, reducing the risk of significant data loss. Here are some key aspects to consider:

Testing Backup Integrity: A backup is only useful if it can be successfully restored. Regularly testing the integrity of backups through mock recovery scenarios can identify potential issues and ensure the system is ready when needed[2].
Encryption & Security: Backing up data introduces additional storage locations that can become targets for cyberattacks. Employing strong encryption ensures that backed-up data remains secure, even if accessed by unauthorised individuals[2].
Version Control & Retention Policies: Backup protocols should incorporate version control to allow businesses to retrieve earlier iterations of data. Retention policies define how long backups are stored, balancing the need for historical data access against storage costs[2].

Adopting Advanced Data Storage Solutions

Choosing the right data storage solution is vital for maintaining data integrity and operational resilience.

Hierarchical Storage Strategy

An ideal storage strategy should capture a means of managing data that organises storage resources into different tiers based on performance, cost, and access frequency. This approach ensures that data is stored in the most appropriate and cost-effective manner.

Storage Type	Benefits	Use Cases
Hot Storage	High performance, quick access	Frequently accessed data, critical business operations
Warm Storage	Balanced performance and cost	Infrequently accessed data that still requires relatively quick access
Cold Storage	Low cost, long-term storage	Archival data, compliance requirements
Archival Storage	Very low cost, long-term storage	Rarely accessed data, historical records

By adopting a hierarchical storage strategy, businesses can optimise their storage infrastructure, balancing performance and cost. This approach enhances operational resilience by ensuring critical data is always accessible[3].

Ensuring Compliance with UK GDPR

Compliance with the UK GDPR is non-negotiable for any business handling personal data.

Key Principles of UK GDPR

The UK GDPR mandates that businesses adhere to seven main principles of data processing:

Lawfulness, Fairness, and Transparency
Purpose Limitation
Data Minimization
Accuracy
Storage Limitation
Integrity and Confidentiality (Security)
Accountability

Businesses must implement strong data protection concepts, maintain a clear and comprehensive privacy policy, and create an IT Security Policy to meet the GDPR’s security requirements[4].

Best Practices for Cloud Security

Here are some best practices that UK businesses can follow to ensure robust cloud security:

Encryption

Employing strong encryption ensures that data remains secure, even if accessed by unauthorised individuals. This applies to both data in transit and at rest within the cloud environment.

Access Controls

Implementing strict access controls and authentication mechanisms protects backup repositories and cloud storage from unauthorised access. This includes multi-factor authentication and role-based access control[2].

Regular Audits and Monitoring

Regularly auditing and monitoring cloud environments helps detect anomalies and potential security breaches early. Tools with anomaly detection capabilities can proactively identify and address irregularities in data patterns[3].

Employee Education

Investing in ongoing employee education is crucial. Employees should be aware of the risks associated with cloud storage and the best practices to protect sensitive information.

Choosing the Right CASB Provider

With the growing demand for cloud security, selecting the right CASB provider is critical.

Key Factors to Consider

Compatibility with Existing Infrastructure: Ensure the CASB can integrate seamlessly with your current systems and cloud providers.
Scalability: As your business grows, your CASB should be able to scale with you.
Customisation Options: Look for a CASB provider that offers customisable policies and controls to meet your specific data control needs.
Support and Compliance Knowledge: A CASB provider with strong knowledge of UK data protection laws and GDPR can provide valuable guidance[1].

Practical Outcomes and Benefits

Implementing these tactics can lead to several practical outcomes and benefits for UK businesses:

Enhanced Data Security: CASBs and robust backup protocols ensure that sensitive data is protected against various security risks.
Compliance: Meeting UK GDPR and other regulatory requirements reduces the risk of hefty fines and reputational damage.
Business Continuity: Effective backup and recovery protocols ensure minimal downtime, maintaining business continuity even in the face of data breaches or disasters.
Operational Resilience: A hierarchical storage strategy and advanced data storage solutions enhance operational resilience by ensuring critical data is always accessible.

Ensuring data integrity in cloud storage is a multifaceted challenge that requires a comprehensive approach. By leveraging CASBs, implementing robust backup and recovery protocols, adopting advanced data storage solutions, and ensuring compliance with UK GDPR, businesses can protect their sensitive information and maintain operational resilience.

As Charlie Bromley-Griffiths, senior legal counsel at Conga, noted, “Organizations must remain committed to investing in their employee’s ongoing education but also in the right technology to safeguard personal data.” By following these best practices and staying informed about the evolving cybersecurity landscape, UK businesses can ensure their data remains secure and compliant in the cloud[5].

In the words of Emma Woollacott, “Given how quickly cyber threats are evolving, the UK GDPR standards may be updated. Businesses need to have the appropriate tools and measures in place to ensure that they are ready to adapt to any legislative changes.” Staying ahead of these changes and investing in the right solutions will be crucial for maintaining data integrity and protecting sensitive information in the cloud.
