Overview: Azure Firewall
If you are considering installing the new Microsoft Virtualization Zone or VPN, you may have come across Azure Firewall. The Azure Virtual Platform and its sister technologies, namely the Azure Site Guard and the Azure Key vault (both free) have been in the market for a long time now. Both are well known in the virtualization industry. So what makes Azure Firewall different and how does it stand out from the competition?
Single firewall appliance per virtual server
In terms of firewall technology, Virtual Private Servers (VPS) are well known and widely used by hosting providers. However, unlike traditional VPS that divides system resources on the basis of physical location, Virtual Private Servers make use of multiple virtual servers. With a single physical server, you will face the problem of resources being shared between several VPS. However, with Azure Firewall, you get a single firewall appliance per virtual server and thus you can configure and deploy your firewall to multiple locations simultaneously. With this level of isolation, you get the benefit of a self-contained solution that minimizes risks and ensures maximum security at the same time.
When you use an enterprise firewall to provide protection for your virtual machines, you get more than what you bargain for. There is a wide range of firewall appliances that can be integrated into the virtualization platform. This means that you can easily adjust and fine tune the firewalls to suit specific purposes like anti-virus, web application prevention, application testing, and content filtering and monitoring. And while these are quite effective in most of the cases, the flexibility provided by the virtualization platform means that you can make some refinements to the firewalls as well.
You can also customize the firewall for your specific needs and set it to automatically kick in or switch off. You can also tweak the settings so that they become more efficient at blocking or reducing the attacks on your virtual systems. For instance, you can increase the port blocking threshold to help prevent unauthorized ports from being opened. You can also have the firewall send only authorized traffic and avoid sending anything to unauthorized users or servers. You can also have the firewall apply rules to deny or restrict access to particular ports or files. And if you want to block IMAP and SMTP, you just need to create a custom rule for those protocols.
The benefits of Azure Firewall
The benefits of Azure Firewall are not limited to running a firewall. Virtualization technology also offers many other advantages including enhanced discovery and loading of information as well as streamlined management of resources and applications. This means that the performance of your virtualization platform will increase and you will enjoy overall system scalability, operational and performance stability, and greater ease of service as well.
But there are certain scenarios in which Azure firewall may not be a suitable option for your virtualization needs. If you are not comfortable with managing the firewall or have no expertise at all, it is best to hire a third-party company to manage this aspect of your virtualization platform. Virtual server administrators and network managers with the necessary skills, knowledge, and expertise will be able to make the most ofAzure firewall. However, if you prefer to do things on your own, here are some tips that you should keep in mind to ensure that your virtual server and business still run smoothly:
– When you are planning for the deployment and the use of Azure firewall, you should first consider how sensitive your data is to outside influences such as security threats and hackers. If you want to protect your business data from unauthorized access, you should choose a virtual server with pre-built firewall protection. In addition to that, you should choose a cloud-based service that provides the necessary security features and services required for proper handling of sensitive data. With this type of service, you can be sure that your business data is always protected and that you will never need to worry about any security issues even when you are not monitoring and managing your virtual servers.
– When it comes to choosing the applications that you will use to manage Azure Firewall, you should choose applications that are designed to manage the different functions and features of this type of firewall. In addition to that, you should also consider the level of granularity that you want to have when it comes to managing the firewall of your virtual servers. For example, you can choose to restrict the entries of particular URL’s or ports. You can also choose to change the settings on the firewall on a daily basis. You should also take note that if you are not an IT professional, it would be wiser to leave these tasks to the experts so that you can be sure that your business is running smoothly.
