Storage security best practices: protecting your data assets

Table Of Contents−

The exponential growth of data creation is unprecedented. Projections indicate that by 2028, this figure will escalate to 394 zettabytes annually.

The advent of generative AI technologies has significantly contributed to this surge, with AI systems generating vast amounts of synthetic data across various domains.

This rapid expansion underscores the critical need for robust storage security best practices to protect sensitive information from evolving cyber threats.

1. Develop comprehensive data security policies

Establishing clear, organisation-wide data security policies is fundamental to effective data protection. These policies should outline security protocols for various data classifications: public, restricted and confidential. Regular updates and accessibility ensure that all employees are informed and compliant, serving as a roadmap for implementing and maintaining security measures across the organisation.

2. Implement Role-Based Access Controls (RBAC)

Utilising RBAC ensures that users can access only the data necessary to perform their jobs, minimising the risk of unauthorised exposure. This should be enhanced with Multi-Factor Authentication (MFA), which requires multiple verification methods before granting access and significantly reduces the likelihood of unauthorised data access.

3. Encrypt data at rest and in transit

Encryption is vital for protecting data both during transmission and while stored. Employing strong encryption standards, such as Advanced Encryption Standard (AES), ensures that even if data is intercepted, it remains unreadable without the appropriate decryption key. Regularly updating encryption keys and storing them securely is crucial to maintaining data confidentiality.

4. Utilise immutable storage solutions

Immutable storage preserves data in its original state, preventing alteration or deletion by unauthorised entities. This is particularly effective against ransomware attacks, as it ensures that backup data remains untainted and recoverable, providing a reliable safeguard for critical data.

A modern data protection solution can keep data backed up in its entirety, ready for immediate recovery. Solutions from HPE and Zerto, a Hewlett Packard Enterprise company, provide consistent edge-to-cloud data protection to help ensure data integrity and availability are continuously maintained.

5. Establish air-gapped backups

Maintaining backups that are physically or logically isolated from primary networks, known as air-gapped backups, adds an extra layer of protection. This isolation ensures that backups remain unaffected in the event of a cyberattack, allowing for swift recovery and continuity of operations.

6. Adopt a Zero Trust security model

The Zero Trust model operates on the principle of “never trust, always verify,” treating every access request as potentially hostile. Continuous verification of user identities and access privileges ensures that only authorised users can access sensitive data, thus reducing the insider risks and external breaches.

7. Conduct regular security training for employees

Human error remains a significant vulnerability in data security. Regular training programs educate employees about best practices, potential threats and the importance of adhering to security protocols. An informed workforce is a critical component in the defence against cyber threats.

8. Monitor and audit access logs

Implementing robust monitoring systems to track access to data storage environments enables the detection of anomalies and potential security incidents. Regular audits of access logs help in identifying unauthorized activities and ensuring compliance with security policies.

The recent cyberattack on London hospitals, which disrupted over 3,000 appointments and operations, highlights the devastating impact of inadequate data security measures. By integrating these best practices into your organisation’s data management strategy, you can significantly enhance the security of your data assets.
