A hybrid cloud model combines a private cloud with one or more public cloud solutions. In a hybrid cloud model, proprietary software enables communication between distinct services. This type of cloud computing model can help gain security advantage provided some critical challenges are addressed.
Following are crucial cybersecurity risks that need to be identified and addressed before implementing the hybrid cloud model:
- Compliance: A hybrid cloud model involves data movement between high-security private cloud and comparatively less secure public cloud. Such data movement may induce compliance issues and make data vulnerable to breaches. Businesses need to take extra measures to ensure that the hybrid cloud model meets compliance requirements. It may be achieved by ensuring that individual private and public cloud networks meet standard data security norms such as GDPR (General Data Protection Regulation). Also, it is important to make sure that the data transfer mechanisms adhere to regulatory requirements.
- Data Privacy: The essence of hybrid cloud model lies in flexible data movement between public cloud and private cloud. In such movement, there are high chances that the data can fall prey to intruder attacks that challenge the organization’s data privacy rules. Organizations should employ measures such as endpoint verification protocol, robust VPN, and strong encryption policy. These measures help in encrypting and protecting data from security breach incidents.
- Distributed Denial of Service: DDoS is another serious cyber-attack that can be initiated from multiple sources to target a single location. Since the attack has various source locations, it becomes difficult to trace and detect. This increases the risk factor. To tackle this, organizations need to maintain a strict monitoring system that can track the inflow and outflow of data. It is important to make sure that the monitoring system should be scalable, responsive, and able to handle multi-vector attacks.
- Service Level Agreements (SLA): Employing a hybrid cloud solution means handing over data governance and accountability to its public Cloud Service Provider (CSP). If the security of such a public cloud is compromised, it can be a severe issue and may lead to critical data loss. To avoid such issues, be careful while signing Service Level Agreements with the service provider to ensure data confidentiality. Make it a point to understand security limitations and strictly define accountability factors.
- Risk Management: Organizations should employ adequate risk management and preventive safety measures to protect their intellectual property from potential risks. Organizations can use tools such as IDS/IPS to scan malicious traffic. Also, maintain a log monitoring system with advanced firewall and security management features.
- Data Redundancy: Organizations should adopt a well-defined data redundancy policy to ensure timely backup of critical data. This can be achieved by maintaining multiple data centers. It also helps in continuing business services during data center outages.

Year 2020 has witnessed a great rise in number of cyber-attacks, specially Ransomware attacks and Business Email Compromise (BEC) attacks including phishing, spear phishing and whaling. These attacks result in data and financial losses. Another reason that has resulted in hike in threat of data threat and data exfiltration is increased number of remote employees due to COVID-19.
The major risk involved in data loss is associated with storing data on-premise or endpoints. Thus, it has become imperative for businesses to adopt a cloud-first approach to data protection.
Here is a step-wise approach to implementing cloud-first data protection strategy:
- First step is to determine if you can trust the cloud service provider’s platform. Analyze if the service provider can meet the data storage requirements of the organization and has the capacity to adapt to any changes to organization’s backup and recovery plans in the future. Check if the provider can:
Support all cloud models including private, public and hybrid.
Protect data on servers, desktops, mobile devices, and third-party cloud apps.
- Know about the data security practices implemented by the cloud service provider. It is important to ensure that organizational data should be encrypted both in flight and rest to avoid unauthorized access.
- Be prepared to combat a data theft attack by designing a well-defined data recovery plan. Ask the cloud service provider, if there is a recovery action plan such as redundant data centers, secondary data center at a different location, etc. for such situations.
- Relying solely on manual processes to back up mission-critical data can be ineffective. As organizations create a large amount of data everyday, manual data backup and management is no longer feasible. Also, processes such as Cloud, DevOps, and automation movements account for a dynamic business environment which further solidifies the need for automated backup policies.
- Consider the level of tech support that the organization would require in case any issue with cloud backup or cloud data management is detected. It is important to have a pre-hand knowledge about how to contact the cloud service provider to reduce the response time. Ask the cloud service provider if it offers different support channels such as Email or chat. Also, make sure that the provider offers 24*7 support across different time zones.
