Virtual machine is a software program or operating system .Virtual machine gives wide range of computing solution ,it’s allow you to run operating system like windows ,linux ,SQL,IBM more or less all.The concept of virtual machine is create virtual environment that’s function system run virtually with it’s own hard drive,RAM ,network card and all other related parts .
The concept of cloud security to secure infrastructure ,application ,network and data .Cloud security is security environment which protect from external and internal security threats.
Challenges to Secure Azure Virtual Machines
Azure give the complete security solution for all virtual machine or infrastructure .Some time organizations face problem due to not following the azure recommended security practices.
Azure VM Security Best Practices
By using Azure recommended Microsoft Azure policy organizations can protect and secure virtual machines .
Create A Policy
Create customized policies to protect virtual machine.Using Azure recommended policies to create security layer between Your virtual machine and attacks.
Secure Against Malware and Attacks
This is very important to secure VM against malware and attacks.You should install anti malware include features like real -time protection,schdule scanning ,malware remediation ,signature updates,engine updates, samples reporting, and exclusion event collection.
Manage Your Virtual Machine Updates
Azure update management solutions to manage operating system updates for Windows and Linux virtual machines .Azure provide automation service for update virtual machines .

Identity Authentication & Authorization
There are few basic services authentication and authorization.
Minimum access using Azure role-based access control
It’s allow and grant specific roles to users in a subscription ,resource group and individual resources.With help of RBAC, you can apply limitation on the user ,who can access and who not for certain services.
Multi factor authentication
MFA is securitysystem which provide multiple authentication process when user log in .
Monitor and restricted external user from internet.An attacker always attacks the public cloud IP address range and constantly scans the management port to attempt “simple” attacks such as common passwords and known, unpatched vulnerabilities.
Control the Azure Virtual Machine security network so that you can limit who can access the Azure IaaS environment on the network.There few service you need to focus and consider.
Monitor Virtual Machine traffic patterns.
Always monitor Virtaul Machine traffic any unauthorized user tried to access
Restrict access to the management port.
Always allow ports where it’s necessary .
