9. Azure Network Security Group
Traffic Rules
Azure Network Security Groups help you control traffic in Azure. You can make rules to decide what traffic gets in or out. NSGs check incoming traffic at the subnet first. Then, they check the network interface. Both must allow the traffic for it to pass. For outgoing traffic, NSGs check the network interface first. Then, they check the subnet. If either blocks the traffic, it will not go through.
Each rule in an NSG has these parts:
NSGs remember connections. If you let traffic in, the reply goes out. You do not need extra rules for return traffic.
Tip: Give your rules clear names and leave space between priority numbers. This helps you change rules later.
Access Control
You can use NSGs to make strong access controls. Split your virtual networks into subnets and give each one an NSG. This keeps traffic apart and makes things safer. Group your virtual machines by what they do with Application Security Groups. This makes rules easier to manage. Use service tags to set rules for Azure services without using IP addresses.
Some best ways to use NSGs are:
Turn on traffic logs to watch what happens.
Use just-in-time VM access to lower risk.
Add conditional access policies for more control.
Connect NSGs with other Azure security tools for better safety.

10. Privileged Identity Management
Privileged Access
It is important to control who has special access in Azure. Privileged Identity Management, or PIM, helps you manage and watch over these roles. With just-in-time access, users only get special rights when they need them. This means they do not have high-level access all the time. It helps stop mistakes and attacks. You can set up approval steps for sensitive roles. Someone must check and approve before extra permissions are given. Emergency access accounts are for backup in big problems. You should use them only when needed to keep things safe.
PIM makes sure people get access only when they need it, and only for a short time.
Risk Reduction
PIM helps lower risks in Azure by using good safety steps. You can make people use multi-factor authentication when they turn on a special role. This adds more safety and stops bad access. You can set time limits so special rights go away by themselves. PIM sends alerts when roles change. This helps you see strange actions early. You can connect PIM with conditional access and device checks. This makes sure users follow safety rules before getting special access.
Monitoring
You need to watch special access closely to keep Azure safe. PIM gives you dashboards and alerts to track who gets roles and when. You get messages when someone turns on a special role. You can look at logs to see who had access, when, and for how long. PIM can find strange patterns and help you act fast. You can set up automatic steps and regular checks. These help you keep access up to date and remove what is not needed.
Give only the permissions that are needed with Azure RBAC.
Use just-in-time access for short-term rights.
Set the longest time someone can have special access.
