What is multicloud security?

Multicloud security is a cloud security solution that provides complete data protection across multiple cloud platforms, including private and public clouds such as AWS, Azure, Google Cloud Platform (GCP), and Oracle Cloud Infrastructure (OCI). Organizations use multi-cloud security to protect all cloud platforms and their various functionalities.

In today’s fast-paced business environment, multicloud adoption is required to survive, where agility and flexibility are important to be competitive. While organizations derive immense benefits from it, the complexity brought in by multicloud environments is bound to introduce security gaps and inefficiencies that prevent organizations from fully benefiting from cloud economics.

To do this successfully, an organization requires a strong multi-cloud security strategy. This article discusses multicloud security architecture, requirements, challenges, and best practices to help an organization optimize its multicloud strategy.

Multi-Cloud Security Architecture

Multi-cloud security architecture secures data and applications in a multi-cloud environment. The architecture typically consists of the following components to build layered defenses in the cloud:

  1. Centralized Management: Centralized dashboards, reporting, and logging to assist with governance and troubleshooting across disparate environments.
  2. Core Services: Networking, segmentation, service insertion, and traffic steering.
  3. Advanced Services: Load balancing, content delivery network (CDN), firewall, web application firewall (WAF), and Zero Trust Network Access (ZTNA).
  4. Identity and Access Management (IAM): Controls user and application access to cloud resources with consistent IAM policies across all cloud providers.
  5. Data Protection: Encrypts data at rest and in transit, with backup and disaster recovery plans to ensure data availability during outages.
  6. Network Security: Deploys secure network connections and protocols to protect data in transit across different cloud providers.
  7. API Management: Protects apps and APIs across multi-cloud architectures for responsive and reliable user experiences.
  8. Compliance and Governance Policies: Ensures organizations meet regulatory requirements and industry standards across all cloud services.
  9. Threat Detection and Response: Enhance the organization’s security response with controls across different cloud environments for efficient detection and remediation.
  10. Ecosystem Integrations: Advanced application delivery and security; L7 gateways, automation tools for software development and deployment.

Importance of Multi-cloud Security Strategy

Cyberattacks are serious threats to businesses, damaging their reputation and affecting businesses financially. Data leaks and security breaches also harm the continuity of organizations. With the adoption of multi-cloud and hybrid cloud infrastructure, these industries are exposed to many risks associated with non-protected cloud environments; these include data loss, unauthorized access, lack of visibility, and increased non-compliance. A single cyberattack may lead to the mistrust of customers, which may come at the cost of the repair of the network and revenue loss.

An effective multi-cloud strategy needs to include a properly working multi-cloud security solution. Here are four benefits of the implementation of multicloud security:

  • More Reliability: Multicloud security protects your business assets, ascertaining the safety of your data and the best working conditions for critical applications. It restricts application access to only authorized users, thus avoiding leaking sensitive information.
  • Constant Security: A safe cloud environment will continuously monitor cyber threats and exposure risks and timely security updates round the clock.
  • Less Cost: Cyber threats might cost your business a lot regarding repair and recovery. Protecting your multicloud environment can save your business from these costly outcomes.
  • Centralized Visibility: Multicloud security solutions enable your business to manage cloud security remotely. You can easily monitor application health, assess exposure risks, and manage users’ access effectively.

Multi-cloud Security Complexities

  • Visibility: The major challenge in cloud security is visibility, and using multi-cloud strategies further exacerbates it. By using third-party cloud providers, one may be denied access to all layers of the cloud computing stack and, hence, have no clear visibility into all security flaws or vulnerabilities. In addition, though cloud providers o**** some monitoring tools, they are mostly incomplete or do not yield sufficient detail about granular logging. In a multi-cloud environment, managing multiple built-in monitoring tools simultaneously becomes impractical.
  • Compliance: Compliance with regulatory requirements is another challenge when working with multiple cloud providers. Companies must meet regulatory requirements across all cloud environments. For instance, an organization may be subject to HIPAA compliance requirements, but AWS may have different compliance policies than Azure, leading to potential compliance gaps.
  • Information Privacy: Information privacy across diversified cloud environments is another critical challenge. Data must be adequately encrypted in transit and at rest to prevent unauthorized access. Organizations must also implement effective backup and recovery processes to deal with data breaches or losses. For example, a company may use Google Cloud Storage for backup and AWS S3 for primary storage. Still, the different encryption and access control policies across every cloud may complicate consistent protection.
  • API security: Secure communication over the Internet is possible using API tools and protocols that allow it with web apps, containers and microservices. However, securing APIs still remains a major challenge. According to the SANS report on multi-cloud, for 58.9% of respondents, poorly configured or insecure APIs or interfaces were a top concern. It exposes the application’s back-end logic and sensitive data, projecting them as a prime target for attackers.
  • Shared Security Model: In cloud computing, the shared security model means you are responsible for certain security aspects while your provider handles the rest. The division of responsibilities varies between providers, so you cannot assume that every platform in your multi-cloud environment offers the same level of security.

Best Practices for Multi-cloud Security

  • Upgrades and Patching: Even between cloud providers, sometimes offering the same infrastructure or workloads, vulnerabilities can change with their respective fixes. Automate software upgrades and patches, making sure they account for the workload, the infrastructure it runs on, and dependencies.
  • Monitoring and Visibility: Monitor multi-cloud environments with tools supporting multiple clouds and visibility across the whole environment. Holistic visibility will help detect, investigate, and respond to cyber threats.
  • Multi-Cloud Storage: Classify data in a multi-cloud environment by putting sensitive data into the most secure storage resources. Plan the geographical distribution of the data to comply with regulations and implement DLP solutions that detect data loss or exfiltration across multiple clouds.
  • Tailor Security Policies to Services: Each workload or application in the multi-cloud must have its security profile and policies based on its use, data sensitivity, and compliance.
  • Automate Security: Extend automation to security practices in public clouds. Adopt a DevSecOps approach where every process on your cloud infrastructure considers security. Ensure every new VM or container undergoes relevant security scans.

Future Outlook

The future of multi-cloud security will evolve with ever-changing business and security requirements. Artificial intelligence and machine learning will automate more security tasks, which will now be able to detect and remediate threats with more speed and accuracy. New technologies, including containers and serverless computing, are increasing in the multi-cloud domain and will continue to require dedicated security measures to protect those technologies. As multi-cloud environments become more complex, so does the attack surface, requiring robust and consistent security solutions and policies across all environments, including on-premises, cloud, and edge.

Organizations should look for multi-cloud security providers with a proven track record of successfully implementing and maintaining such solutions. Providers must update their security intelligence and controls regularly to remain aligned with the ever-evolving threat landscape and industry best practices.
