Detailed Control Evidence

CC6.1 - Logical and Physical Access Controls

Control Objective: The entity implements logical and physical access controls to protect against threats from sources outside its system boundaries.

LM-001: Log Data Access Controls

Control Description: Access to log data is restricted through multi-layered security controls including AWS IAM policies, encrypted storage, and role-based access management.

Implementation Details:

{
  "aws_iam_policy": {
    "principal": "qwestly-log-shipper-user",
    "permissions": [
      "s3:GetObject",
      "s3:PutObject", 
      "s3:ListBucket"
    ],
    "resources": [
      "arn:aws:s3:::qwestly-logs",
      "arn:aws:s3:::qwestly-logs/*"
    ],
    "conditions": {
      "IpAddress": "GitHub Actions IP ranges",
      "SecureTransport": true
    }
  }
}

Evidence of Effectiveness:

AWS CloudTrail logs showing access patterns
IAM policy reviews conducted quarterly
No unauthorized access attempts recorded
MFA required for all administrative access

Testing Procedures:

Access Control Testing: Quarterly penetration testing of AWS access controls
Permission Validation: Monthly review of IAM policies and user permissions
Breach Simulation: Annual red team exercise targeting log storage systems

Control Frequency: Continuous (automated) + Quarterly review

CC6.2 - System Boundaries and Data Classification

Control Objective: Prior to issuing system credentials and granting system access, the entity registers and authorizes new internal and external users whose access is administered by the entity.

LM-002: Data Classification and Boundary Controls

Control Description: Log data is classified according to sensitivity levels and stored within defined system boundaries with appropriate protection mechanisms.

Data Classification Schema:

Classification Levels:
  - Public: System status and health metrics
  - Internal: Operational logs and performance data  
  - Confidential: Authentication and access logs
  - Restricted: Administrative and security events

Boundary Controls:
  - Network: VPC isolation and security groups
  - Application: API authentication and authorization
  - Data: Encryption at rest and in transit
  - Administrative: Role-based access controls

Implementation Evidence:

S3 bucket policies restricting public access
Encryption at rest using AES-256
Network isolation through VPC configuration
Data retention policies automatically enforced

Monitoring and Validation:

Daily verification of bucket access controls
Weekly scan for publicly accessible data
Monthly review of data classification accuracy
Quarterly audit of system boundary effectiveness

CC6.3 - Access Control Systems and Procedures

Control Objective: The entity authorizes, modifies, or removes access to data, software, functions, and other protected information assets based on roles, responsibilities, or the system design and changes.

LM-003: Access Management Procedures

Control Description: Formal procedures govern the authorization, modification, and removal of access to log management systems based on role requirements and principle of least privilege.

Role-Based Access Matrix:

Role	Supabase Access	AWS S3 Access	GitHub Actions	API Endpoints	Monitoring
CTO (Dominick)	Service Role Key	Full Admin	Admin	Full	Full
CEO (Adam)	None	Read-Only	Read-Only	Read-Only	Full
Engineering	None	None	Read-Only	Limited	Read-Only
