Security Challenge on Azure

There are few common security related questions when we start planning migration to Azure:

  • How can we restrict the ingress and egress traffic on Azure ?
  • How can we route the traffic on Azure ?
  • Can we have Firewall kit, Intrusion Prevention System (IPS), Network Access Control, Application Control and Anti – Malware on Azure DMZ ?

This blog post intention is to answer above questions using following Azure features combined with Security Virtual Appliance available on Azure Marketplace:

  • Azure Virtual Network (VNET)
  • Azure Network Security Groups (NSGs)
  • Azure Network Security Rule
  • Azure Forced Tunelling
  • Azure Route Table
  • Azure IP Forwarding
  • Barracuda NG Firewall available on Azure Marketplace

One of the most common methods of attack is The Script Kiddie / Skiddie / Script Bunny / Script Kitty.… [Keep reading] “Secure Azure Virtual Network Defense In Depth using Network Security Groups, User Defined Routes and Barracuda NG Firewall”

NSG is one of the feature Enterprise customers have been waiting for.

What are Network Security Groups and how to use them?

Network Security Groups allow us to control traffic (ingress and egress) on our Azure VNET using rules we define and provide segmentation within VNET by applying Network Security Groups to our subnet as well as Access Control to VMs.… [Keep reading] “Secure Azure Virtual Network and create DMZ on Azure VNET using Network Security Groups (NSG)”
