As we know, passwords are no longer strong. In Verizon Data Breach Investigations Report (2017), it says, 81% of hacking-related breaches used either stolen or weak passwords. Multi-factor authentication can provide an extra layer of security to the sign-in process but it doesn’t eliminate the requirement for passwords. In one of my previous blog posts, I explain how we can enable Azure Active…
When we connect two networks via VPN connection, we only allow certain traffic to pass through (In most scenarios). This is the normal security best practice. We normally use a firewall to do this. When it comes to Azure, we may also need to connect virtual networks . In such situation, By using Azure Firewall, we can control the traffic between virtual networks. More info about Azure firewall…
In this blog post we are going to learn about Active-Active Azure VPN gateways. There are two methods to connect two virtual networks.
1. Azure VPN Gateways
2. Azure VNET Peering
Azure VNET Peering
Azure VNET peering allows connecting virtual networks seamlessly via Azure backbone infrastructure. This is similar to inter-VLAN routing in on-premises networks. The traffic will not pass via the…
By using source network address translation (SNAT), we can translate a local IP address, a pool of local IP addresses, or even a subnet to a specific public IP address for outbound connections. This is important as it will help to control traffic flow through firewalls by using ACLs. In Azure, we can do SNAT by using Azure NAT gateway. This allows virtual machines in the subnet to use a specific…
