Everything is working fine… until one day, you receive multiple alerts:
You think:
“But only my office staff should access this server. Why is the whole world hitting it?”
NSG stands for Network Security Group. It is like a security guard standing at the door of your Azure Virtual Machine .
Just like a security guard checks:
NSG decides what traffic can go IN and OUT of your Azure resources.
NSG is used to increase the security of your cloud environment. In the cloud, your VM is directly accessible from the internet, so you need a gatekeeper.
NSG helps you:
NSG keeps your Azure environment safe and controlled.
NSG works using rules. Each rule decides whether traffic should be ALLOWED or DENIED.
NSG checks every packet and decides: “Allow this” or “Block this.”
Imagine you live in a building with a security guard. You give instructions:
Similarly, you give NSG instructions:
NSG behaves like a digital security guard.
NSG is simple but powerful for network protection.
Summary: Use NSG anywhere you need simple network-level protection.
NSG is a security filter that controls inbound and outbound traffic in Azure.
Yes, NSG is completely free.
On VM NIC or on subnets — both options work.
NSG is one of the most important security features in Azure. If you are learning Azure, mastering NSG is your first step towards cloud security.
KEY TAKEAWAY:
NSG = Your cloud security guard.
It protects VMs and subnets by allowing only safe traffic and blocking all other traffic.

Great presentation style by Zameer Sir with lots of opportunities to ask questions and talk about real life examples along with online practicals during the training which all made for a really enjoyable and informative course." "This has more than met my expectations.
Attari Classes is Best Classes For MCSE / CCNA / MCSA / Azure / VMware / AWS. I have completed My Azure Training and very happy and satisfy with course quality and content. I was wondering how practical will happen as it was my 1st online course but The Trainer Zameer Sir is one of the Best teacher, many times if we stuck or got confused in something he help us by taking remote during online classes to make us understand well. Even after classed if we stuck somewhere in practice he guide us on WhatsApp and I really appreciate his help and effort for student. I am grateful to you for everything you taught us. one of the best think about Attari classes is LMS, whole course content whatever in online classes is also available on LMS so you can practice by playing online live recorded lecture and can study PDF study material whenever you want. I would like to Thanks Attari classes for inventing this very Helpful feature. if you want to learn best quality content related to MCSE / CCNA / MCSA / Azure / VMware / AWS I would recommend Attari Classes they are best in teaching.
I have enrolled for azure administrator course and is nearing to an end. The trainer Mr. Zameer make sure all the attendees are able to understand the concepts on the course through a hands on experience and also helps them with the practicals when we are stuck. They provide the access to lms, which helps us to practice and refresh what is studied. This helped me alot. Am also planning to do more courses with them. Thanks for the amazing support from attari classes.
azure training is best at attari classes.the way zameer sir explains concept is exceptional. full hands on practical is provided.attari classes follows a very different approach i.e 85% practical and 15% theory which is very good.
I took VMware training from Attari Classes long ago and it helped me alot in my professional growth, I already knew the teaching way of Maqsood Sir so there was no second thought before joining AWS batch, even though it was online session due to Pandemic it was 100% interactive and completely hands-on session with real life examples. No matter the number of time you ask question Sir make sure to clear them out and if someone get stuck during practicals Sir make sure to take the remote and guide them to fix the problems so that no one stays behind. And LMS (Learning Management System) in the other hand is great facility provided by Attari Classes, If in case you didn't understand something or miss the lecture it really helps to cover those topics. Tip and Tricks is the bonus
Azuure Online Training : Training is Unique, Zameer Sir is very unique in terms of providing Lab instructions and making students do the lab perfectly. I recommand Attarii Classes for any training now or in the future as well. Approach of training is awasome !!!!
My experience of AZURE training by Zameer sir was really amazing. He explains every topic in a detailed way and also very descriptive while sharing knowledge. A very calm and patient teacher, also helps to understand concepts deeply. My experience with Attari classes has been 10/10 till now as I have also done VMware training before which was with the expert Maqsood Sir!
