Security Best Practices

Security recommendations for deploying All ID.

Network security

Network segmentation

Deploy services in separate network tiers:

Public Tier    → Load Balancer (internet-facing) or Api Gateway
Private Tier   → Peer, Facematch
Database Tier  → MySQL (isolated, no internet access)

Implementation:

  • Deploy load balancer in public subnet

  • Deploy services in private subnets

  • Deploy database in isolated subnet

  • Use NAT gateway only if external bureaus are enabled

IP whitelisting

Restrict external access to known IP addresses.

Certta IPs:

Implementation:

  • Configure load balancer to accept traffic only from whitelisted IPs

  • Apply IP restrictions at firewall/security group level

  • Document approved IPs and review regularly
