6 free network vulnerability scanners

Though you may know and follow basic security measures on your own when installing and managing your network and websites, you'll never be able to keep up with and catch all the vulnerabilities by yourself.

8 ways to improve wired network security

We sometimes focus more on the wireless side of the network when it comes to security because Wi-Fi has no physical fences. After all, a war-driver can detect your SSID and launch an attack while sitting out in the parking lot.

Free tools for Windows Server admins

Whether you’re in IT or an average end user, here’s what you need to know about the changes and new features.

Super-fast Wi-Fi: Cisco, Ubiquiti access points top out at nearly 400Mbps

Earlier this year we tested several consumer-level 802.11ac routers. Here, we take a look at two enterprise-level access points. They're a part of the so-called "Wave 1" phase of the 802.11ac standard: both access points support up to three spatial streams and 80 MHz wide channels, offering theoretical data rates up to 1.3Gbps. But just as we saw with the 802.11ac routers, you won't get throughput rates nearly that fast.

Hot hotspot gateways

Offering Wi-Fi can be a good way to increase return customers and boost revenue in retail stores, hotels, cafes, etc. And it provides convenience for contractors and associates working in corporate offices and conference rooms.

Smartphone tools to keep your Wi-Fi network humming

In the early days of Wi-Fi, site surveys were fairly basic and involved running around with a laptop looking at simple signal levels. The next step was mapped-based tools that provided a good visual of Wi-Fi coverage, but still involved carrying a bulky laptop around.

Review: Best tools to set up secure Wi-Fi for BYOD

Deploying the enterprise mode of Wi-Fi Protected Access (WPA2) with 802.1X authentication provides great Wi-Fi security, but complicates the client configuration and connection process. In bring-your-own-device (BYOD) environments, this can cause user frustration and a spike in help desk calls. The solution is to deploy an automated configuration process so users can easily connect their devices without invention from IT staff.

Tips for troubleshooting 802.1X connections

Implementing 802.1X authentication, which includes everything from setting up a RADIUS server to keeping end users connected, isn't easy.

Low-cost RADIUS servers for Wi-Fi security

Remote Authentication Dial-In User Service (RADIUS) servers are common in enterprise networks to offer centralized authentication, authorization and accounting (AAA) for access control. But RADIUS servers can also be useful in small and midsize networks to enable 802.1X authentication and WPA2 (802.11i) security for Wi-Fi nets.
