Securing Virtual Networks

Traditionally, enterprises have thought about network security using a “moat and castle” approach. That is, the perimeter of the corporate network was the point of protection—the place where firewalls and proxies were deployed to protect the enterprise. In the increasingly virtual world of networking, where hosts may move between trusted internal private clouds and public ones, the perimeter becomes the virtual switch rather than enterprise network boundaries.

Networking Virtualization and Software-Defined Networking
Virtual NICs, virtual switches, and the like are common-place in today’s Hyper-V environment. In these scenarios, the use of SDN technology provides a software abstraction for managing both physical and network devices and the communication between those devices and the applications.
Using an Application-Centric Approach to Make the Most of Software-Defined Networking

You might have read about software-defined networking (SDN) technologies, such as those found in Microsoft Windows Server 2012 R2 Hyper-V, which can provide a way for tighter integration between applications and the network. The goal of SDN is to have a network that is aware of and that adjusts to the needs of different applications, through software. SDN has the ability to deliver a network that is optimized for application workloads with varying communication needs.

Optimizing your Network with Windows Server 2012 QoS
Part of the challenge of running a virtualized infrastructure is dealing with the network requirements of varying application workloads. QoS can help.

Troubleshooting Group Policy 

Organizations large and small rely on Group Policy to help manage security configuration and desktop lockdown. But despite its critical role, little information is available that truly explains how Group Policy works and how you can fix it when it’s broken.

Group Policy Design Best Practices
Learn to design a Group Policy deployment to improve security and optimize performance, without your users being aware of it.
What's Wrong with Group Policy?

Windows Server 2008 R2 and Windows 7 Group Policy
The Group Policy improvements in Windows Server 2008 R2 and Windows 7 are evolutionary rather than revolutionary. With the possible exception of adding some PowerShell automation support for Group Policy management, this Group Policy release is rather ho-hum.
PowerShell and Active Directory
The wait for full-fledged PowerShell Active Directory support is over. Microsoft has shipped an AD module and PowerShell Drive provider to make managing AD from PowerShell a snap.
Control Application Execution with SRP
Group Policy's software restriction policy (SRP) feature gives admins a powerful tool to control what code their users can run. Learn to use hash and path rules to set up application whitelists and blacklists and maintain a more secure environment.
