The real power of the NSA 3500By Frank Ohlhorst | Print
Re-Imagining Linux Platforms to Meet the Needs of Cloud Service Providers
Unified Threat Management comes to enterprise networks via SonicWall's latest security appliances, the NSA series.
Monitoring is another area that SonicWall has vastly improved. The unit's new security dashboard offers a quick view of the status of the device and the related security services so administrators can quickly tell what is happening on the network and drill down into more detail with a simple click of the mouse. The NSA 3500 also offers historical data and can generate comprehensive reports. Those reports can demonstrate the effectiveness of the product, help administrators understand traffic flow and categorize usage.
The real power of the NSA 3500 comes from the UTM capabilities. Here, the deep packet inspection engine works in conjunction with anti-malware capabilities to examine each packet for a multitude of threats. Normally, that would be a slow and processor-intensive process. The NSA 3500 makes quick work of the packet analysis thanks to the unit's multicore processor. Its four processor cores can be assigned to handle different tasks, such as anti-virus or spam analysis. That simple implementation of a now common technology can make all the difference in the world when it comes to performance.
