One of the biggest challenges incloud security risk assessmentisthe lack of transparencyregardingcloud provider operations and security controls.
Key Issues with Limited Visibility:
Cloud providers manage infrastructure at a global scale:
Customerscannot directly inspectsecurity implementations.
Rely onthird-party attestationslikeSOC 2, ISO 27001, CSA STARinstead of direct assessments.
Multi-tenancy complexities:
Cloud customersshare infrastructurewith other tenants.
Data isolation mechanisms (e.g., virtual private clouds, encryption)must be trustedwithout direct verification.
Regulatory compliance challenges:
Organizations handling sensitive data (e.g., healthcare, finance)requirestrict controls.
Cloud providers may not offer sufficient audit logsor control overdata residency and processing.
Incident response limitations:
In traditional IT, organizations controllog access, forensic analysis, and recovery.
In the cloud,incident investigation depends on the provider’s logging and notification practices.
