Firewalls and remote working?

With remote working becoming the new normal it might be shocking to know that only 45% of firms have conducted additional security checks. 

IT departments have to constantly be on their toes as threat definitions change and newly discovered potential software weak points arise. 

Microsoft Azure Firewall, which is a part of Dynamics 365 platform, prevents malware from entering corporate networks, blocks phishing attacks, and protects business-critical data.  

Azure Firewall Manager creates a single destination for IT administrators to configure and manage their Microsoft Azure Firewall applications. Your IT department might be interested to know that they will probably achieve around 35 firewall updates in less than 10 minutes! 

Transform my firewall?  

By removing traditional hardware-based firewalls and replacing them with software as a service (SaaS), security is provided in near real-time, and scales as needed to meet demand.  

Microsoft’s invests $1 billion each year on security research and development, and they employ 3,500 security experts, which is why most Fortune 500 companies are choosing to use Microsoft Azure. 

“If you look at any enterprise, they have firewalls closer to the applications and have multiple micro-perimeter networks,” says Gopikrishna Kannan, a principal program manager for the Microsoft Azure Firewall team. “This expands the network firewalls deployed by the customer. We’ve seen customers with 100 firewalls. And if the system administrator calls in sick, then what do you do? And if there is a break-in, then their stock suffers.” 

Microsoft Azure Firewall was built in 2017, and Azure Firewall Manager was added in 2019, which enables engineers to update threat definitions, then rapidly deploy them across a cloud.  

It also allows administrators to centrally create firewall policies in Azure Firewall Manager. It contains definitions to allow or deny Layer 3 to Layer 7 traffic, which are the layers that extend from the network layer to the application layer. Firewall policies can also be applied to multiple firewalls. 

In addition, firewall rules for a specific region are customisable by defining a firewall policy that inherits a baseline Firewall policy. This helps enforce a centrally defined policy and yet provides flexibility for administrators to customize Firewall rules. This feature also allows administrators to restrict access privileges using custom role-based access controls. 

In contrast to traditional firewalls that tended to be very complex pieces of technology, Microsoft Azure Firewall, offers simpler, task-specific security tools that streamline management.

Close contact with the development team, listening to their explanations, meant that I acquired a deeper understanding of the platform and was thus able to help my employees move seamlessly from the old to the new Dynamics 365 CRM.
