JIT VM Access - One way to reduce VM attack surface area

When a cloud resource is publicly accessible, it means it also ready for attack.

In this post, we will see how JIT helps azure virtual machine with public IP enabled securing briely.

Organizations need a VM with public IP sometimes. In this kind of scenario, we need secure the VM from attacker.

Just-In-Time (JIT) is one of the way to secure the VM in following ways.

  • It can block RDP (3389) and SSH (22) ports.
  • It allows to set specific port can be opened for a specific time for specific IP ranges.
  • It can work with VMs only have private IP as well.
  • Azure Bastion can be used to block traffic for a private IP VM until JIT access is enabled.

To enable JIT VM access, Go to configuration and enable it.

Glimpse - Azure function migration from .net6 in-process to .net8 isolated Microsoft/Azure periodically announces the end of support for some services and ask us to migrate to a new version/release when they come up with a robust solution than the deprecated. In this post we are going to see a glimpse/UI configuration change of azure function 𝗺𝗶𝗴𝗿𝗮𝘁𝗶𝗼𝗻 𝗳𝗿𝗼𝗺 .𝗻𝗲𝘁𝟲 𝗶𝗻-𝗽𝗿𝗼𝗰𝗲𝘀𝘀 𝗺𝗼𝗱𝗲𝗹 𝘁𝗼 .𝗻𝗲𝘁𝟴 𝗶𝘀𝗼𝗹𝗮𝘁𝗲𝗱. Here, I'm not going to deep dive about the migration whereas going to see the illustration of changing .net version from UI. For learning, GUI is the best place to start. So, as a dev guy we would prefer azure portal mostly. Consider a scenario that, you're requested to migrate your existing .net6 function app to be migrated .net8 isolated, you would go to settings panel and try to change the version in configuration, but the option would be disabled, it was disabled for me initially. Shocking and Afraid! After some point of ...

Azure Devops - How to use classic pipeline variable group in YAML pipeline Hi All! When we need to use a group of variables in a pipeline, we can go for variable group instead of variables. The main usage of variable group is that can be used it across multiple pipelines in the same project. For example, I have a below variable group in my azure Devops. By default variable groups can be used across classic pipelines without any explicit permission granted but that variable group could not be used by YAML pipelines typically. So, How how can I use that variable group in my YAML pipeline? We can achieve it through "Pipeline permissions" option on top of variable group page. In the below image, I grant permission to my dotnet6app YAML pipeline to use variable group We can revoke if we don't need a YAML pipeline should not access variable group as below. Now, I want my all pipelines should use variable group. I don't want manual intervent...
