What is Wireless LAN?

A Wireless LAN or WLAN is a local area wireless network system in which data is transferred between the networked computers wireless through the high frequency radio waves.  The major benefit of having a WLAN is the mobility and the users can have access to the network resources from the nearby locations.  High bandwidth, faster real time network access, simple network configurations and location independent access to the IT administrators and the network administrators have made WLAN the best solutions for the corporate and the home users.  Hospitals, universities and multiple storey offices prefer to install WLAN where wired network is difficult to install.

 

WLAN Security

Security is a major issue in any type of computer network.   Major issues like data theft, hacking, virus attack and personal information lost can be occurred if the security of the computer network has been compromised.  Most of the large computer networks are divided into the smaller networks for security management and data management. 

 

WLAN uses radio waves so hackers and intruders try to enter your network and get access to the sensitive information of your server.  To prevent your WLAN from the wireless specific attacks from the hackers you need to implement the proper security settings in your network. 

 

Insecure wireless user stations, access points, laptops, network printers and bar code scanners pose greater risk to the security.  Improperly configured WLAN can originate network vulnerabilities.  Default SSIDs (Service Set Identifier) should be changed to some complex names. 

Configure the Access points in such a way that they should disable the broadcast mode.  Encryption and user authentication provides an additional layer of security for the WLAN.  Implement strict security policies for each station in your computer network.  Continuous monitoring of the network traffic, protocol analysis, statistical anomaly and the monitoring of the WLAN attack signature, the network administrators are able to detect the attacks against the WLAN.

Wireless LAN Certification

Cisco Systems offer three levels of Wireless LAN certifications that testify the candidate’s skills and knowledge in designing, maintenance and deployment of the Cisco Wireless LAN Solutions in a small or big organization.  Cisco Wireless LAN Certification and experience is in great demand in the overall IT industry.

The Wireless LAN certification includes the following:

  • Cisco Advanced Wireless LAN Design Specialist
  • Cisco Advanced Wireless LAN Sales Specialist
  • Advanced Wireless LAN for Field Engineers
  • Advanced Wireless LAN for Account Managers
  • Wireless LAN Wireless LAN for Account Managers Exam (WLANAM)
  • Wireless LAN Wireless LAN for System Engineers (WLANSE)

Valid CCNA (Cisco Certified Network Associate) certification is the prerequisite for the Cisco Wireless LAN Support Specialist certifications.
