Setup and Configure Azure Bastion to Securely connect to Azure Virtual Machines

Last week, Microsoft Azure Team has calmly announced the preview release of one of the exciting features known as Azure Bastion. The concept of using an Bastion Host is nothing new, where one would configure one of the Virtual Machines as Bastion or HopBox and then connect to other private virtual machines configured in the virtual network. This would help providing some security as instead of securely managing all of the virtual machines in an given network, you would need to securely connect and manage only Bastion Host, which is having Public IP address assigned for the connections. However, the onus of configuring all the required networking setup, installing and configuring ssh and rdp protocols, timely patching and hardening of the Bastion Host still lies with the Azure/AWS Administrator.

Mount a Windows NTFS Disk in Linux

Almost all of the Windows OS disks use NTFS as a filesystem. It has been there since long time. However it is proprietary to Microsoft and is therefore not open sourced. By default, you’ll not be able to mount NTFS disk in the linux distributions like CentOS, RHEL etc. However it is possible to install a driver that allows us to do this so that we can read and write data to an NTFS disk.

In this blog post, we’ll see how to do the same. For the demo purpose we’ll be mounting a NTFS disk, inside CentOS.
