Thanks Adam for the great tutorial demo. However, in your demo topology about Network security group, you applying the NSG to the subnet seems easy to misleading that NSG is to apply to subnet. However, it should be apply to servers directly

@Adam in 04:05 --While adding inbound security rule in our NSG, we have source, SPR, destination, DPR, protocol and action. In protocol field we have 4 options ie,(Any, TCP, UDP and ICMP). So my question is, Is this possible to select more than one option (in protocol field)? for example protocol: TCP amd ICMP. Or its only one option at a time?
@AdamMarczakYT
@AdamMarczakYT 3 года назад
One at the time, that's why they added option Any to allow for all of them.

I have a question about how NSG works. So if I were to create a rule to allow RDP with a priority of 100, and another rule to block RDP with a priority of 101, would RDP be allowed in this case?

NSG allow/block specific port not service. NSG can't be used as Application(service) firewall. For example, if i decided to use ssh on port 2224, NSG rule that block 22 port can't prevent my attempt to connect to host via ssh.

VMSS = identical VMs, if you change OS they are no longer identical, so no. Thanks for watching! :)

Hi Adam, thanks for the great content. I just have one question... in 1:05 you say that all traffic comming from the internet would be allowd... but I think there the "implicit" deny rule. Therefore, traffic must be explicitly permitted...
@AdamMarczakYT
@AdamMarczakYT 3 года назад
Great question. Notice that you said you have a 'default rule', that means you also have a NSG. In this example, I have shown a diagram with no NSGs. In that case all ports are exposed to the internet/intranet. In Azure your can create resources without NSG if you want, but by default templates include NSG so most people don't even realize that. I used this as an example as to why NSGs are so important for us.

@stephenadams2397

I know this is probably just for example purposes but was there any reason you placed your logic service in the same subnet as the web subnet? I'm thinking you could have had Web Subnet => Logic Subnet => DB Subnet as that seems more in-line with your security architecture when you used ASG.
@AdamMarczakYT
@AdamMarczakYT 3 года назад
You are correct, this is just for simplicity sake. 😀
@DanielWeikert
@DanielWeikert 3 года назад
The NSG is an own resource correct? So after creating how do you link specific resources to the group and are rules for one nsg then applied to all resources linked or can they be customized for each resource?
@AdamMarczakYT
@AdamMarczakYT 3 года назад
Great question Daniel. Inside of the NSG resource there are panels which allow you to associate NSG to either specific Network Interfaces of Virtual Machines or to entire Subnet. Lot's of info on this can be found here if you are interested: docs.microsoft.com/en-us/azure/virtual-network/manage-network-security-group?WT.mc_id=AZ-MVP-5003556

So if you have port 80 or 22 or any port for SSH , https or RDP. I can scan it using public ip via Nmap. Find vulnerability and i would attack your web server first and escalate to root privilege then move laterally to the data base and extract any files using Steganography.
@AdamMarczakYT
@AdamMarczakYT 3 года назад
"Find vulnerability" - that's the tricky part. Azure Services are always up to date with latest security patches.
@denkozlov4220
@denkozlov4220 2 года назад
I didn't understand how to configure subnets within Network Security Groups, how would I attach inbound or outbound rules for the whole subnet range of IP addresses?
@AdamMarczakYT
@AdamMarczakYT 2 года назад
Rules are affecting those that the NSG is attached to. If NSG is attached to Network Interface it will only affect that NIC. You need to attach NSG to an entire subnet for the rules to affect entire subnet.

@AdamMarczakYT
@AdamMarczakYT 2 года назад
If you have 100 VMs but you want to expose only 50 via NSG you would need to create many rules for them based on static IPs or ranges. It's easier to group those 50 in ASG and add that ASG in NSG.
