More SSL Encryption is on the Way

Before we start, we wanted to announce a new cool monthly prize to our readers. Today we’re giving you access to a cool godaddy ssl coupon codes website that’ll save you money on SSL certificates. Once you read this whole article, you’ll realize why these are incredibly important in the hyper tech world to come (plus it makes your readers feel safer!).

The Next Generation Firewalls (NGFWs) are designed to protect against everything that goes into a network. It doesn’t matter whether the information originates from the Internet, mobile devices, a cloud system or a private network. The NGFW stands guard against hostile e-mails, attachments, Trojans, bots and other ways that malicious software and malware may try to penetrate a network. This system detects and protects against a malware threat before it breaches the network wall. It’s that simple.

If a visitor makes a request for a web page to the network, the NGFW acts instantly to give that visitor the web page free of malware and other harmful computer viruses. In a nutshell, that means that pages served by the network are free of mischief. Networks using NGFWs can assure visitors that the pages they visit or download are virus and malware clean and contain only the vital and useful information they seek.

The NGFWs are equivalent to a high-tech cleaning service that scrubs clean every image, copy, banner ad, video file and link.

The bugs and viruses are washed away, and what’s left are clean, virus-free data waiting for customer pickup. While it’s true that a malware protection system embedded in a computer system can accomplish this work, the NGFWs work by stopping the infection before it embeds itself into  the network.

Think of the image of a doctor who wears a surgical mask.  That barrier prevents bad bugs from entering his physical body. That mask filters out and isolates the bad germs. The idea of isolating and detecting a problem before it breaches the computer network wall is a better solution than cleaning out a malware infection that has already infected the computer network.

After information is filtered through the NGFWs and passed into the network, other safe-guarding technology goes to work to guard the network and clients from malware infection. These protection layers are at work to protect both the networks and devices used by visitors.

The NGFW systems have evolved as a first line of defense against malware. They operate to checkmate threats before reaching the network and before anti-virus software on the computer kicks in.

Computer security experts are recommending that companies consider building layers of protection using different NGFW vendors. To detect and defeat malware, each NGFW vendor must individually update their software to meet new threats. Every vendor won’t do this simultaneously. Through layering NGFWs, business networks can be assured that one NGFW company will likely have a threat covered while other NGFW companies update protections.

The NGFW systems operate fast. This is necessary so that the network isn’t bogged down. These systems also uses deep packet inspection in order to examine data in depth. The NGFW system can also approve which personnel have access to the network and its applications.

Palo Alto Networks, Check Point, Juniper and Dell sonicWALL all offer next generation turnkey systems. Here’s a review of the Dell system by Dell.

The Dell Next Generation Firewall is the base of the SonicOS Platform. It acts as a gateway protection, an inspector for SSL sessions and control and intelligence for granular applications. It’s a more advanced security application that integrates application intelligence, visualization and control with gateway protection that is capable of meeting various threats. The system reduces complexity. It slides into the network effortlessly and at a low cost.

Application traffic is monitored and displayed in real time via the Dell sonicWALL Application Intelligence and Control. This process guarantees necessary bandwidth to critical applications while cutting back bandwidth to non-critical applications.

Inside Dell sonicWALL is the Deep Packet Inspection engine that inspects every packet of data. This new technology is superior to old proxy designs that disassembled data, laundering it through anti-virus programs. This old process created inefficiency and low performance.

The WAN Acceleration Appliance Series reduces loads and can accelerate traffic productivity two-fold. It does so by filtering traffic that’s dangerous or not productive and passing through traffic that needs acceleration. This enhances WAN performance.

Finally, by placing all the eggs into a single platform, complexity and time are reduced when managing, deploying and configuring a security system. Configuration wizards and an ingenious Web interface are included in the Dell Next Generation Firewall which makes for an easy setup into any network.
