Zero Trust Architecture: Implementation Guide

Mon, 08 Apr 2024 00:00:00 +0000

Zero Trust isn’t a product you buy—it’s a security philosophy you implement. Here’s a practical approach to building zero trust in cloud environments.

Core Principles

Never Trust, Always Verify
Assume Breach
Least Privilege Access
Verify Explicitly

Network Layer

Traditional perimeter security assumes everything inside is trusted. Zero trust rejects this.

Micro-segmentation

# Terraform: Security groups for micro-segmentation
resource "aws_security_group" "app_server" {
  name        = "app-server"
  vpc_id      = var.vpc_id

  ingress {
    from_port       = 443
    to_port         = 443
    protocol        = "tcp"
    security_groups = [aws_security_group.load_balancer.id]
  }

  egress {
    from_port       = 5432
    to_port         = 5432
    protocol        = "tcp"
    security_groups = [aws_security_group.database.id]
  }
}

Services can only communicate with explicitly allowed paths.
