Cloud network security requires clear, actionable steps for effective implementation. This guide provides direct instructions for securing your cloud network infrastructure, with specific focus on practical implementation and measurable outcomes.
Core Security Components
Essential elements for immediate implementation:
Network Segmentation Setup
1. Create Virtual Networks
- Configure address spaces
- Set up subnets
- Enable service endpoints
- Implement network peering
2. Security Group Configuration
- Define inbound rules
- Set outbound rules
- Configure application security groups
- Implement service tags
Implementation Steps
Follow these direct steps for secure network deployment
Initial Setup
1. Network Architecture
- Deploy hub-and-spoke topology
- Configure routing tables
- Enable network monitoring
- Implement DDoS protection
2. Access Controls
- Configure NSG rules
- Set up Azure Firewall
- Enable Just-in-Time access
- Implement Private Link
Security Control Implementation
Execute these security measures:
Network Protection
1. Firewall Configuration
- Deploy Azure Firewall
