Introduction to CIEM
Cloud Infrastructure Entitlement Management (CIEM) focuses on managing and securing identities, permissions, and entitlements in cloud environments. It addresses the unique challenges of cloud identity sprawl.
The Cloud Identity Problem
Challenges:
95% of cloud permissions are unused
Average 40,000 permissions per cloud account
Human and machine identities multiply
Static credentials create risk
Compliance complexity
CIEM Value Proposition
Benefits:
Visibility into all entitlements
Least privilege enforcement
Risk-based prioritization
Continuous monitoring
Compliance automation
Cloud Identity Risks
Over-Privileged Identities
Common Issues:
Admin access by default
Copy-paste policies
Legacy permissions
No access reviews
Unused Permissions
Statistics:
95% of permissions never used
Attack surface expansion
Audit complexity
Compliance violations
Machine Identity Sprawl
Challenges:
Service accounts multiply
API keys everywhere
Secrets in code
No lifecycle management
Cross-Account Access
Risks:
Trust relationship abuse
Lateral movement paths
Confused deputy attacks
Privilege escalation
