Conquering the 7 Cyber Threats in Mixed Cloud Infrastructures

Conquering the 7 Cyber Threats in Mixed Cloud Infrastructures

In today's digital world, businesses are increasingly relying on hybrid cloud environments to power their operations. However, this shift brings new challenges, particularly in terms of security. To address these issues, several best practices have emerged to ensure a unified, proactive security and management approach across hybrid cloud environments.

Enhancing Visibility and Detection

To gain full network visibility and break down silos, it's crucial to employ tools that classify traffic by application. This centralized monitoring not only provides insights across on-premises and multiple cloud platforms but also integrates automated detection and real-time insights into Continuous Integration/Continuous Deployment (CI/CD) pipelines. Early detection of configuration errors and threats is key to maintaining security.

Preventing and Remedying Misconfigurations

Adopting Infrastructure as Code (IaC) for consistent, repeatable configuration management is a vital step in reducing human error and policy drift. Combining this with continuous configuration monitoring and automated remediation ensures secure setups.

Enforcing Consistent Security Policies

Standardizing and enforcing strict access controls and security policies across all environments is paramount. The Zero Trust approach, which verifies every user, device, and connection dynamically, segments workloads, and applies uniform protections, is a powerful tool in this regard.

Seamless Network Integration

Flexible security tools that function transparently across various networks, from virtualized to software-defined, are essential for maintaining connectivity and policy enforcement during scaling or infrastructure changes. Network segmentation and micro-segmentation reduce lateral movement risks.

Robust Identity and Access Management (IAM)

Shifting from IP-based access controls to identity and group-based policies that follow users across environments is a crucial step in securing access. Implementing strong IAM, supported by multi-factor authentication (MFA), role-based access control, and least privilege principles, is key to consistently securing access.

Compliance and Governance Frameworks

Aligning cloud security with compliance standards such as NIST CSF, ISO 27001, PCI DSS, and GDPR is essential. Clearly defining shared responsibility models with cloud providers is also important, as is formulating governance that includes vendor lock-in mitigation, multi-cloud visibility, exit strategies, and resilience planning for regulatory demands.

Addressing the Cloud Skills Gap

Establishing a Cloud Center of Excellence (CCoE) that brings together IT, security, compliance, finance, and operations teams is a valuable strategy for addressing the cloud skills gap. Investing in training programs focused on hybrid cloud security tools, automation, and policy management can help close knowledge gaps.

The Risks and Solutions

98.6% of organizations have misconfiguration issues that risk their data and infrastructure. Tools like Cloud Security Posture Management can help detect and remediate misconfigurations. Role-based access controls ensure that users can only retrieve what they need and nothing more.

Visibility gaps in hybrid cloud environments are the top security issue, as monitoring requires different tools and creates blind spots that increase the risk of noncompliance and undetected breaches. A centralized monitoring tool that works across on-premises and cloud systems can help bridge visibility gaps, enabling real-time threat detection and automatic alerts.

27% of organizations identify IT technicians as the biggest skill gaps in their teams, with most security incidents in hybrid environments caused by a lack of expertise or proper training. Companies should invest in ongoing training programs and build cross-functional teams to address the cloud skills gap.

Different regions and industries have their own privacy and security laws, making it difficult to stay compliant in a hybrid cloud setup. Public cloud providers offer robust security measures, but their tools don't always integrate with local servers, leading to inconsistent security policies and a wider attack surface.

Hybrid clouds often have too many access doors but not enough locks to secure them, increasing the risk of unauthorized entry. A multi-cloud strategy can optimize costs by combining best-of-breed services from different vendors, but when multiple clouds and on-premises systems are connected, the data that travels between them may lack secure pathways, opening the door to interception and information leaks.

To address these issues, businesses can set up standardized policies and use unified controls that enforce the same rules and configurations across all platforms. Data classification tools can help clearly label sensitive information and set rules about where these files can be stored or shared. Encouraging employees to earn industry certifications and keep skills up to date through regular upskilling is also crucial.

In conclusion, by implementing best practices such as those outlined above, businesses can enhance their security and simplify the login process through single sign-on and multi-factor authentication. Automated compliance checks and regular audits, supported by data residency controls, can help ensure compliance with important regulations. By addressing visibility gaps, misconfigurations, inconsistent security policies, network integration, identity and access management, compliance and governance, and the cloud skills gap in a hybrid cloud environment, businesses can achieve a secure and efficient digital transformation.
