• Wireless LAN access control: Managing users and their devices

  Wireless LAN access control may not be as simple as 802.1X authentication. Network managers will have to shoot for policy creation, device fingerprinting and network integration.  Continue Reading

• Planning a virtualization firewall strategy

  Creating a virtualization firewall strategy entails determining exactly how you want to protect your virtual environments and then implementing firewall segmentation for security.  Continue Reading

• Virtual network appliances: Benefits and drawbacks

  There's lots of talk about network virtualization benefits, but are virtual network appliances all they're cracked up to be? Only in some scenarios.  Continue Reading

• Migrating to 10 GbE enables data and storage network convergence

  Migrating your data center to 10 Gigabit Ethernet (10 GbE) enables higher available bandwidth with fewer ports to manage, and lends itself to data and storage network convergence -- both of which are necessary for a high-performing virtualized ...  Continue Reading

• Securing the wireless guest network: Authentication and management

  If you're implementing an enterprise-class wireless guest network, tighter security is crucial. A guest wireless LAN must support better visibility and user control.  Continue Reading

• Firewall change management and automation can curb human error

  Firewall change management can enable firewall management automation so that human errors will be less likely to destroy performance and network admins will know the status of their firewall configuration.  Continue Reading

• Live migration networking: Enter long-distance data center bridging

  Live migration networking poses all sorts of challenges, including the potential need for long-distance data center bridging that results in traffic trombones. When it comes to server virtualization networking, is it possible to avoid the pitfalls?  Continue Reading

• How to ensure WLAN performance optimization

  To ensure wireless LAN performance optimization, you’ll need to implement new WLAN measurement and testing tools and conduct WLAN performance testing periodically even after network implementation.  Continue Reading

• Do Web application firewalls complicate enterprise security strategy?

  Using Web application firewalls should only be one slice of your overall enterprise network security strategy. Even then, users must be aware that application firewalls can leave behind vulnerabilities.  Continue Reading

• Network application performance monitoring: Storage to the user

  Application performance monitoring tools must provide visibility to everything from storage I/O to remote end-user access and a whole lot in between. Here’s what your monitoring tools should show.  Continue Reading

• End-to-end network application performance monitoring

  Network application performance monitoring inevitably leads to the use of multiple monitoring tools at once. That doesn’t have to be a management nightmare.  Continue Reading

• Wireless LAN troubleshooting: How to get proactive

  Wireless LAN troubleshooting and WLAN diagnostics can be done proactively with a new set of tools, including WLAN managers and distributed sensor platforms that track and problem solve on complex networks.  Continue Reading

• Integrating public and private cloud services

  Network managers must support integrated public and private cloud services because users will go under the radar to use public cloud services that help them get their work done more easily.  Continue Reading

• WLAN testing: Wireless intrusion prevention systems and centralized testing tools

  WLAN testing has grown to accommodate the full-time surveillance necessary for super-speed 802.11n technology and mobile applications. Now WLAN testing can be done with AP-based wireless intrusion prevention systems and more.  Continue Reading

• Application-layer firewalls defend against attacks up the stack

  Application-layer firewalls must be combined with lower-level network security firewalls in order to implement a network firewall strategy that defends against low-level attacks as well as application-aware attacks.  Continue Reading
