Microsoft is touting software-defined networking (SDN) security capabilities in your coming Windows Server 2019 product as among its top-ten networking features, as documented in an announcement recently.
SDN technologies are utilized for the current flagship Windows Server 2016 product, too, but SDN to get a big part of Microsoft’s product marketing for this year’s model. For example, in its top-ten feature countdown list for Windows Server 2019, Microsoft earlier had suggested that SDN technology will enable so-called “software-defined datacenters,” which could be considered to be another top networking feature.
At this occassion, as its No. 4 top networking feature, Microsoft is emphasizing this new server’s SDN security benefits, including automatic subnet encryption, improved firewall auditing, an continuing development of access control lists (ACLs) to logical subnets, virtual network peering and IPv6 support.
The subnet encryption capability in Windows Server 2019 is true of the encryption of network traffic between virtual machines. Likely to automated process involved where “any packet that leaves a VM is automatically encrypted while it passes to some other destinations on the very same back-end network,” Microsoft’s announcement explained. Should your vulnerability are available during this process, information is automatically updated. The announcement suggested in which feature will alleviate the need check if the encryption for apps can be date, as it also automatically handles application-level encryption. This automated process just happens around the same subnet. When traffic is sent between subnets, it can be unencrypted, Microsoft explained, from this document.
The firewall logging feature in Windows Server 2019 in concert with the Hyper-V host and lets organizations initiate audits of firewall performance. To generate videos to verify that network boundaries are working properly. It’ll also indicate if thez network is under an anxiety attack or if a breach has occurred, in accordance with Microsoft’s announcement. Microsoft will be touting this feature’s capability generate logs that “are consistent in format with Azure Network Watcher,” meaning that Azure Network Watcher tools may be used with this feature.
Microsoft and this is highlighting the ability to automatically apply ACLs to logical subnets with Windows Server 2019. “This translates to , any SDN managed VM associated with a VLAN based network will automatically try out the necessary ACLs applied,” the announcement explained.
Microsoft is suggesting it’s new virtual network peering capability in Windows Server 2019 supplies to improve potential throughput and latency issues for communications between virtual networks. This feature “combines the virtual routers in associated virtual network allowing them to communicate with one, without having to traverse via the gateway,” the announcement explained.
Lastly, there’s SDN support for IPv6 in Windows Server 2019. It truly does work across “virtual network address spaces,” “virtual IPs” and “logical networks” to back up IPv6 traffic. This selection enables security and not being a security feature by itself. “All of the safety measures of SDN now employ IPv6 addresses and subnets, including Access Control Lists and User Defined Routing,” Microsoft explained in association with SDN support for IPv6.
Window Server 2019 to get at the preview stage, however it’s expected to reach “general availability” (commercial release) later 2010. Some of its capabilities is tested today, although GitHub projects resulting from this week’s SDN and security announcements turned out to be lacking content at press time.
In related news, Microsoft announced the discharge of another preview of Windows Server 2019 (build 17744) earlier this week. Throughout this release, Microsoft is extolling new Hyper-V Server 2019 capabilities.
