Review Chapter 8 on Advanced Network Security in Google Cloud Platform

Key Takeaways

Private Google Access enables VMs without public IPs to securely access Google APIs
Identity-Aware Proxy (IAP) provides centralized authorization for VMs and apps without VPNs
Cloud NAT offers managed, highly available network address translation for outbound connections
Cloud Armor protects against DDoS and application-layer attacks with customizable security policies

Topics

Private Google Access

Allows VMs without external IPs to access Google APIs and services
Enabled at subnet level in VPC Network settings
Requires specific DNS configuration for googleapis.com and gcr.io domains
Uses default internet gateway for routing; custom routes possible for specific use cases
Firewall rules must allow egress to Google API IP ranges

Identity-Aware Proxy (IAP)

Centralizes authorization for secure remote access to VMs and applications
Implements application-based access control using Google Cloud Identity or federated providers
Supports additional security checks like geolocation and device verification
Can be extended to on-premises applications using IAP connector
Supports TCP forwarding for SSH, RDP, and other protocols

Cloud NAT

Managed, software-defined NAT service with high availability and scalability
Allows outbound internet connections but restricts inbound traffic
Supports alias IPs and relies on default internet route in VPC
Created using Cloud Router and NAT configuration

Cloud Armor

Provides DDoS protection and Web Application Firewall (WAF) capabilities
Protects applications behind HTTPS, SSL proxy, or TCP proxy load balancers
Offers pre-configured and custom security policies for L3-L7 filtering
Integrates with Content Delivery Network (CDN) to protect origin servers
Supports both backend and edge security policies with rule prioritization

Next Steps

Practice implementing Private Google Access on subnets
Configure Identity-Aware Proxy for secure application access
Set up Cloud NAT for outbound internet connectivity
Create and apply Cloud Armor security policies to protect web applications
Prepare for the next chapter on Google Cloud Key Management Service
