The hybrid cloud is a popular choice for enterprises that want to modernize and stay adaptable in the digital era. By combining public clouds, private clouds, and on-premises resources, the hybrid cloud offers flexibility, scalability, and cost-efficiency. However, securing the hybrid cloud can be challenging, as data and assets are distributed across multiple environments and locations. Traditional perimeter-based security strategies are no longer sufficient, as they assume that everything inside the network is trusted and everything outside is not. This creates a false sense of security and exposes the organization to external and internal threats.
To address the security needs of the hybrid cloud, enterprises need to adopt a zero-trust approach. Zero trust is a framework that assumes that nothing is trusted by default, and everything must be verified before granting access or privileges. Zero trust aims to wrap security around every user, device, and connection, for every single transaction. Zero trust also provides continuous monitoring and response, to detect and mitigate any anomalies or breaches.
In this blog post, we will explain the benefits and challenges of the hybrid cloud, the principles and components of the zero-trust model, and how to implement zero trust in the hybrid cloud environment. We will also introduce Vinca Cyber, a global cybersecurity services and products company that can help you achieve zero-trust cybersecurity in the hybrid cloud.
Benefits and Challenges of the Hybrid Cloud
The hybrid cloud is a combination of public clouds, private clouds, and on-premises resources, that are integrated and orchestrated to provide the best of both worlds. The public cloud offers on-demand, scalable, and pay-as-you-go services, that can support dynamic and innovative business needs. The private cloud offers more control, security, and customization, that can meet specific compliance and performance requirements. The on-premises resources offer legacy and critical data and applications, that can be retained and protected in-house.
The benefits of the hybrid cloud include:
- Flexibility: The hybrid cloud allows enterprises to choose the best environment for each workload, based on the cost, performance, and security factors. Enterprises can also move workloads between environments, as needed, to optimize resources and efficiency.
- Scalability: The hybrid cloud enables enterprises to scale up or down their resources, depending on the demand and availability. Enterprises can leverage the public cloud for peak or seasonal workloads, and the private cloud or on-premises resources for steady or predictable workloads.
- Cost-efficiency: The hybrid cloud helps enterprises reduce their capital and operational expenses, by using the public cloud for variable and low-cost services, and the private cloud or on-premises resources for fixed and high-value services. Enterprises can also avoid vendor lock-in and optimize their cloud spending, by choosing the best provider for each service.
- Innovation: The hybrid cloud fosters innovation and digital transformation, by providing enterprises with access to the latest technologies and services, such as artificial intelligence, machine learning, big data, and analytics. Enterprises can also experiment and test new ideas and solutions, in the public cloud, without affecting their core operations.
However, the hybrid cloud also poses some challenges, especially in terms of security. Some of the challenges are:
- Complexity: The hybrid cloud increases the complexity of the IT infrastructure, as it involves multiple environments, providers, platforms, and tools. This makes it difficult to manage and secure the hybrid cloud, as it requires consistent policies, processes, and standards, across the different components.
- Visibility: The hybrid cloud reduces the visibility of the data and assets, as they are distributed across multiple locations and networks. This makes it hard to monitor and audit the hybrid cloud, as it requires comprehensive and integrated tools, that can provide real-time and holistic insights.
- Compliance: The hybrid cloud complicates the compliance of the data and assets, as they are subject to different regulations and standards, depending on the environment and location. This requires enterprises to understand and adhere to the various compliance requirements, and to ensure that their cloud providers and partners are also compliant.
- Threats: The hybrid cloud exposes the data and assets to more threats, as they are accessible from multiple endpoints and devices, both on- and off-premises. This increases the attack surface and the risk of data breaches, as attackers can exploit the vulnerabilities and gaps in the hybrid cloud.
To overcome these challenges and to secure the hybrid cloud, enterprises need to adopt a zero-trust approach.
Principles and Components of the Zero-Trust Model
The zero-trust model is a framework that assumes that nothing is trusted by default, and everything must be verified before granting access or privileges. The zero-trust model was developed by John Kindervag in 2010, while he was a principal analyst at Forrester Research. The zero-trust model is based on the principle of “never trust, always verify”, and it aims to wrap security around every user, device, and connection, for every single transaction.
The zero-trust model also provides continuous monitoring and response, to detect and mitigate any anomalies or breaches. The zero-trust model can help enterprises achieve better security outcomes, such as:
- Enhanced network performance, due to reduced traffic on subnets
- Improved ability to address network errors
- More simplified logging and monitoring process, due to the granularity
- Quicker breach detection times
The zero-trust model consists of several components, that work together to implement the zero-trust principles. Some of the components are:
- Identity and access management (IAM): IAM is the process of verifying the identity and credentials of the users and devices, and granting them the appropriate level of access and privileges, based on the principle of least privilege. IAM also involves enforcing multi-factor authentication (MFA), single sign-on (SSO), and password management, to enhance the security and convenience of the users and devices.
- Data protection: Data protection is the process of securing the data, both at rest and in transit, across the hybrid cloud. Data protection involves encrypting the data, using strong and standardized algorithms and keys, and applying data loss prevention (DLP) and data classification policies, to prevent unauthorized access or leakage of the data.
- Endpoint security: Endpoint security is the process of securing the endpoints and devices, that access the hybrid cloud. Endpoint security involves installing and updating antivirus, firewall, and anti-malware software, and applying device management and configuration policies, to prevent malware infection or compromise of the endpoints and devices.
- Network security: Network security is the process of securing the network, that connects the hybrid cloud. Network security involves segmenting the network, using micro-segmentation and software-defined networking (SDN), and applying firewall, intrusion detection and prevention system (IDPS), and virtual private network (VPN) policies, to prevent unauthorized or malicious traffic or access to the network.
- Cloud security: Cloud security is the process of securing the cloud services and platforms, that are part of the hybrid cloud. Cloud security involves choosing reputable and compliant cloud providers and partners, and applying cloud security posture management (CSPM), cloud workload protection platform (CWPP), and cloud access security broker (CASB) policies, to ensure the security and compliance of the cloud services and platforms.
How to Implement Zero Trust in the Hybrid Cloud Environment
Implementing zero trust in the hybrid cloud environment is not a one-time project, but a continuous journey, that requires a strategic and holistic approach. Some of the steps to implement zero trust in the hybrid cloud environment are:
- Assess the current state: The first step is to assess the current state of the hybrid cloud environment, and identify the assets, data, users, devices, services, platforms, and tools, that are involved. This step also involves identifying the risks, threats, vulnerabilities, and gaps, that exist in the hybrid cloud environment, and prioritizing them based on the impact and likelihood.
- Define the desired state: The next step is to define the desired state of the hybrid cloud environment, and establish the goals, objectives, and metrics, that will guide the zero-trust implementation. This step also involves defining the policies, processes, and standards, that will govern the zero-trust implementation, and aligning them with the business and security requirements.
- Choose the solutions and tools: The third step is to choose the solutions and tools, that will enable the zero-trust implementation, and integrate them with the existing hybrid cloud environment. This step involves selecting the best-of-breed solutions and tools, that can provide the zero-trust components, such as IAM, data protection, endpoint security, network security, and cloud security, and ensuring that they are compatible and interoperable with the hybrid cloud environment.
- Implement and test: The fourth step is to implement and test the zero-trust solutions and tools, and verify that they are working as expected, and achieving the desired state. This step involves deploying and configuring the zero-trust solutions and tools, and conducting regular testing and validation, to ensure that they are effective and efficient, and that they are not causing any disruption or performance issues.
- Monitor and improve: The final step is to monitor and improve the zero-trust implementation, and ensure that it is adaptive and resilient, in the face of changing business and security needs. This step involves collecting and analyzing the data and metrics, that measure the zero-trust implementation, and providing feedback and recommendations, to improve the zero-trust implementation. This step also involves updating and refining the policies, processes, and standards, that govern the zero-trust implementation, and ensuring that they are consistent and compliant.
