How to Assess the Security of Your DRaaS Solution

Using a robust disaster recovery solution such as Disaster Recovery as a Service (DRaaS) helps to keep your data secure. That said, DRaaS solutions vary in their feature sets and, hence, the level of security they offer. With that in mind, here is a straightforward guide on how to undertake an effective DRaaS security assessment.

Security risks in DRaaS

Here are the 10 main security risks in DRaaS.

Data breaches

DRaaS involves transferring sensitive data to third-party cloud environments, which increases the risk of unauthorized access. Misconfigured cloud settings or inadequate encryption can expose critical data to cybercriminals.

Insider threats

Employees or contractors with access to DRaaS systems may intentionally or unintentionally misuse their privileges, leading to data theft or compromise.

Third-party vulnerabilities

DRaaS providers may face their own security issues, such as outdated software, weak internal controls, or inadequate incident response processes, which could affect the organization using their services.

Compliance challenges

Organizations handling sensitive or regulated data (e.g., healthcare or financial information) must ensure that DRaaS providers comply with standards like GDPR, HIPAA, or PCI-DSS. Non-compliance could result in legal penalties and reputational damage.

Data sovereignty risks

If DRaaS providers store data in multiple geographic regions, it may conflict with local laws or expose the organization to different legal jurisdictions, potentially violating data residency requirements.

Ransomware risks

While DRaaS aims to protect against ransomware, improperly secured backup systems or unpatched vulnerabilities could allow attackers to infiltrate and encrypt backups.

Attacks on service providers

DRaaS providers can become targets of distributed denial-of-service (DDoS) attacks, rendering recovery systems unavailable during critical times.

Mismanagement of access controls

Inadequate identity and access management practices can lead to unauthorized access, especially if multi-factor authentication (MFA) is not enforced.

Incomplete data recovery

If the DRaaS provider fails to maintain up-to-date backups or if data synchronization processes are flawed, organizations may experience incomplete or inconsistent data recovery, leading to operational disruptions.

Vendor lock-in

Organizations may become overly dependent on a single DRaaS provider. This can limit flexibility and expose the organization to risks if the provider’s services degrade or become unavailable.

How to assess DRaaS security

Here is a 7-step process to assess DRaaS security. These points should all be checked by active testing to validate the security and reliability of the DRaaS solution in practice rather than just in theory.

Identify compliance requirements

Determine the regulatory standards applicable to your organization, such as GDPR, HIPAA, or PCI-DSS. Ensure the DRaaS provider complies with these requirements and provides certifications or audits as evidence.

Evaluate data encryption

Assess the encryption protocols used for data in transit and at rest. Verify that strong encryption standards (e.g., AES-256) are employed and that encryption keys are securely managed.

Assess access controls

Review the provider’s identity and access management (IAM) practices. Confirm the use of multi-factor authentication (MFA), role-based access controls (RBAC), and regular access audits to prevent unauthorized access.

Review backup and recovery processes

Evaluate the provider’s backup frequency, data consistency checks, and recovery point and time objectives (RPO/RTO). Ensure their processes protect against incomplete backups and ransomware attacks.

Examine physical security

Verify the physical security of the provider’s data centers, including measures like biometric access, surveillance, and disaster-resilient infrastructure.

Audit security policies and incident response

Assess the provider’s policies for detecting, responding to, and mitigating security incidents. Look for evidence of proactive threat monitoring and clear procedures for incident handling.

Evaluate third-party risks

Ensure the provider conducts regular audits of their supply chain and subcontractors to address potential vulnerabilities.

Best security practices for DRaaS

Here are 7 of the best security practices for DRaaS.

Encrypt data

Always encrypt sensitive data during transmission and storage. Use strong encryption standards, such as AES-256, to protect against unauthorized access.

Implement strong access controls

Use multi-factor authentication (MFA) and role-based access controls (RBAC) to ensure only authorized personnel can access the DRaaS environment. Regularly review and update user permissions.

Vet DRaaS providers

Choose providers with proven security credentials, such as ISO 27001, SOC 2, or compliance with GDPR, HIPAA, or other relevant standards. Review their security policies, certifications, and audit reports. Mitigate the risk of vendor lock-in by ensuring that data can be migrated to another provider or on-premises system if needed.

Perform regular backups and testing

Schedule frequent backups to maintain up-to-date recovery points. Conduct regular disaster recovery drills to verify that backups are complete, accessible, and recoverable.

Monitor and audit activity

Implement logging and monitoring tools to track user activity, detect anomalies, and respond to potential security incidents promptly. Conduct regular security audits of the DRaaS solution.

Ensure data residency compliance

Verify that the provider complies with data residency laws and stores data in approved locations.

Address ransomware risks

Use immutable backups and air-gapped storage to prevent ransomware from encrypting recovery data.
