🔐 Security and Permissions - Least Privileges

Security Best Practices

The CFM Tips MCP server follows AWS security best practices and requires only read-only permissions. Here are the key security principles:

Core Security Principles

  • Read-Only Access: All operations are read-only - no create, update, or delete permissions

  • Least Privilege: Grant only the minimum permissions required for cost analysis

  • No Resource Modification: The tool cannot modify, terminate, or create AWS resources

  • Audit Trail: All API calls are logged via CloudTrail for security monitoring

  • Credential Security: Supports multiple secure credential methods (IAM roles, profiles, etc.)

Recommended Security Setup

1. Create Dedicated IAM Role (Recommended)

# Create a dedicated role for CFM Tips aws iam create-role --role-name CFMTipsCostAnalysis --assume-role-policy-document '{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Principal": { "AWS": "arn:aws:iam::YOUR-ACCOUNT-ID:user/YOUR-USERNAME" }, "Action": "sts:AssumeRole" } ] }' # Attach the CFM Tips policies to the role aws iam attach-role-policy --role-name CFMTipsCostAnalysis --policy-arn arn:aws:iam::YOUR-ACCOUNT-ID:policy/CFMTipsComprehensiveReadOnly

2. Enable CloudTrail Monitoring

# Ensure CloudTrail is enabled for API monitoring aws cloudtrail describe-trails --query 'trailList[*].[Name,IsLogging]' # Create CloudTrail if not exists aws cloudtrail create-trail --name cfm-tips-audit --s3-bucket-name your-cloudtrail-bucket aws cloudtrail start-logging --name cfm-tips-audit

3. Use IAM Profiles (Alternative)

# Create AWS CLI profile for CFM Tips aws configure --profile cfm-tips export AWS_PROFILE=cfm-tips

Security Validation

Verify Read-Only Access

# Test that no write operations are possible aws iam simulate-principal-policy \ --policy-source-arn arn:aws:iam::YOUR-ACCOUNT-ID:role/CFMTipsCostAnalysis \ --action-names ec2:TerminateInstances s3:DeleteBucket rds:DeleteDBInstance \ --resource-arns "*" # Should return "implicitDeny" for all write operations

Monitor API Usage

# Monitor CFM Tips API calls via CloudTrail aws logs filter-log-events \ --log-group-name CloudTrail/CFMTips \ --start-time $(date -d '1 hour ago' +%s)000 \ --filter-pattern "{ $.userIdentity.type = \"AssumedRole\" && $.userIdentity.arn = \"*CFMTipsCostAnalysis*\" }"

Network Security

VPC Endpoint Configuration (Optional) For enhanced security in private networks:

# Create VPC endpoints for AWS services (optional) aws ec2 create-vpc-endpoint \ --vpc-id vpc-12345678 \ --service-name com.amazonaws.us-east-1.cost-optimization-hub \ --route-table-ids rtb-12345678

Firewall Rules

# Required outbound HTTPS access to AWS APIs # Allow outbound to: *.amazonaws.com on port 443 # No inbound connections required

Credential Management

Environment Variables (Development)

export AWS_ACCESS_KEY_ID=AKIA... export AWS_SECRET_ACCESS_KEY=... export AWS_DEFAULT_REGION=us-east-1

IAM Role (Production - Recommended)

# No credentials needed when running on EC2/ECS/Lambda with IAM role # Role automatically provides temporary credentials

AWS CLI Profile (Multi-Account)

# ~/.aws/config [profile cfm-tips-prod] role_arn = arn:aws:iam::PROD-ACCOUNT:role/CFMTipsCostAnalysis source_profile = default [profile cfm-tips-dev] role_arn = arn:aws:iam::DEV-ACCOUNT:role/CFMTipsCostAnalysis source_profile = default

Service-Specific Security Notes

Cost Optimization Hub

  • Requires enrollment in AWS Cost Optimization Hub

  • No additional security considerations beyond IAM permissions

Trusted Advisor

  • Requires Business or Enterprise support plan

  • Some checks may require additional permissions

Performance Insights

  • Must be enabled on RDS instances

  • Provides database performance metrics (no sensitive data)

S3 Analysis

  • Only accesses bucket metadata and configuration

  • Does not read object contents or data

  • Respects bucket policies and ACLs

Compliance Considerations

Data Privacy

  • Tool analyzes only AWS service metadata and metrics

  • No application data or user content is accessed

  • All analysis is based on AWS service configurations and usage patterns

Audit Requirements

  • All API calls are logged via CloudTrail

  • Tool provides detailed logging of all operations

  • Supports compliance reporting through AWS Config integration

Multi-Account Security

# For cross-account analysis, use cross-account roles aws iam create-role --role-name CFMTipsCrossAccountRole --assume-role-policy-document '{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Principal": { "AWS": "arn:aws:iam::MANAGEMENT-ACCOUNT:role/CFMTipsCostAnalysis" }, "Action": "sts:AssumeRole" } ] }'
