RF-Wall: RFID Firewall for Network Security

Here is RF-Wall from NeoCatena which is a startup based out of California. You all must be wondering what it is? This is one of the latest security appliance aimed to act as a firewall between RFID interrogators and middleware. As per the company RF-Wall will be protecting RFID systems from fake RFID tags and the ones encoded with malware. RF-Wall is based on the following risks associated with RFID networks - one of them is the cloning of RFID tags and other is the spread of viruses to back end systems.

There are still doubts as to whether this kind of security threat exists but NeoCatena believes these kinds of threats exist and it is based on experiments conducted in 2004. So what will RF-Wall do? It will be using digital signature to find out whether information stored in RFID tags has been manipulated or not and in case some threat is detected the business process will be blocked sending a warning signal to the system administrator. Though there is still no valid proof as to whether such risks exists or not but as per company claims RF-Wall is being tested by a couple of companies and this is certainly making me interested in keeping a watch on the developments which will be taking on this front.
