Cloud Supply Chain Attacks

Summary

Cloud Supply Chain Attacks involve compromising cloud service providers, third-party vendors, or software dependencies to infiltrate target organizations, often resulting in widespread impact across multiple customers and services.

Key Characteristics

• Targeting cloud infrastructure, platforms, or software supply chains to inject malicious code or backdoors.
• Exploitation of trusted relationships between cloud providers and their customers.
• Use of compromised software updates or cloud services to propagate attacks.
• Potential for large-scale impact due to the interconnected nature of cloud ecosystems.
• Often difficult to detect due to the trusted nature of supply chain components.

Defensive Controls

• Implement strict vendor risk management and continuous security assessments.
• Use software bill of materials (SBOM) to track and verify software components.
• Enforce multi-factor authentication and least privilege access for cloud environments.
• Monitor cloud environments for unusual activity and conduct regular security audits.
• Adopt zero trust principles to limit lateral movement within cloud infrastructure.
