Cloud Network Security
Cloud Network Security Challenges
Cloud environments introduce unique network security challenges including shared responsibility models, dynamic infrastructure, multi-tenancy, and diverse connectivity options. Organizations must adapt traditional network security approaches for cloud-native architectures.
Virtual Network Design
Design cloud virtual networks with security zones, subnets for different tiers, and network isolation between workloads. Implement VPCs (AWS), VNets (Azure), or VPCs (GCP) with proper CIDR planning, route tables, and security group configurations.
Cloud-Native Security Controls
Leverage cloud-native security including security groups for stateful firewalling, network ACLs for stateless filtering, cloud firewalls for advanced threat prevention, and private endpoints to avoid public internet exposure for cloud services.
Hybrid Cloud Connectivity
Secure hybrid cloud connections using dedicated circuits (AWS Direct Connect, Azure ExpressRoute), encrypted VPN tunnels, or SD-WAN solutions. Implement redundant connectivity, extend security policies consistently, and monitor cross-environment traffic.
Multi-Cloud Security
Multi-cloud strategies require consistent security across providers. Use cloud security posture management (CSPM) tools, implement uniform tagging and policies, centralize logging and monitoring, and consider third-party solutions for cross-cloud visibility and control.
