Cisco Wireless LAN Controller: Getting Through It All

The Cisco wireless LAN controller has recently been up to an issue because there are still plenty of attackers who wish to exploit its service by means of doing unauthorized access to some vulnerable networks.

There are at least five issues which have been clearly identified by the authorities. They are as follows:

The first issue has something to do with both the public and private read-only and read-write SNMP strings of community that could easily be exploited by these attackers. It has been found out that it could easily be used to change or read the wireless LAN controller configurations via the SNMP.

The second vulnerable issue to the wireless LAN controller is due to the error that comes along during the processing of the deformed Ethernet traffics that obviously permit the illegal attackers to be able to seep into the wireless LAN controller so there are interruptions happening in the service. The next issue is concerned with some errors in relation to the Network Processing Unit of NPU during the processing stage involving the SNAP packets. In here the malformed traffic containing unexpected length amounts in its headers are hindered by the wireless LAN controller from pursuing with the traffic so the service condition is somehow tampered.

The fourth issue has something to do with the presence of the hard coded service passwords which are utilized for the troubleshooting purposes and could be physically used by the attackers in controlling over the affected line of Lightweight Access Point.

Finally, the last issue is due to the error in the processing stage of the WLAN ACLs. The configuration could be invalidated thereby resulting to a change in the security status of the entire wireless network system.

It is sad to note that the Cisco wireless LAN controller, although it has not been directly involved itself, has been widely affected by the abovementioned vulnerabilities. The Cisco systems, in its attempt to levy the damage done to its name, has come up with recently updated networking portfolios via the Cisco Unified Wireless Network strategies launched by the company. This breakthrough introduces new networking solutions using the wireless LAN controller technologies.

The Cisco wireless LAN controller is now gifted with higher levels of security, resiliency, and then scalability to fit into the requirements of the critical applications in the corporate world. The full integration of its architecture and latest technological breakthroughs, the product is guaranteed to have a more responsive foundation that would ensure the security of the user.

More so, the Cisco wireless LAN controller is bordered on the specs of the company's Integrated Services Router or ISR solutions. There are currently at least five hundred thousands of Cisco wireless LAN controller that is already deployed all around the world as embedded with top notch security features, high performance, modularity, and voice support. The product is also geared at lower costs. Its high security level is now an assurance that aside from being convenient and easy to use, it is also a means of great protection. It has the capacity to support up to six APs which are lightweight, zero touch capacities, and with an advanced monitoring, configuration, and management factors.

Cisco Systems is indeed an all around company. Problems may confront their products but the company only treats these things as challenges to their existence.
