Security in Azure

• Any system can be said fully reliable only when there are proper security measures are taken.
• Having just a single security measure for your cloud infrastructure is never enough. You need in-depth security.
• If you are having an On-Premises setup, you are in charge of physical hardware, buildings, staff, and computing capabilities. you need to protect your on-premises assets, and you will have several layers of defense. You'll have swipe cards to get into the building, security guards, restricted access to servers, usernames, passwords, firewalls, and much more.
• For Azure, there are seven general layers of security in cloud computing.

Layers of security for Azure

1. Physical: This is the actual data center. Only authorized personnel have access.
2. Identity and Access: This relates to the Azure Active Directory, which controls all access to Azure and the identity of all users, applications, and connections.
3. Perimeter: This is the protection against DDoS attacks, volumetric attacks, protocol attacks, and more.
4. Network: This is the filter of traffic to and from Azure using virtual networks and applying security standards.
5. Compute: This component protects against intruders trying to get into your virtual machines or databases.
6. Application Gateways and Firewalls: They provide security to outbound flows to the internet that your application may require and in-bound flows from the users. In short, it provides security to your Azure applications.
7. Data: The data on Azure is encrypted and protected against anyone unauthorized reading it or making sense of it.
