What is Wi-Fi?

  Wi-Fi has become widespread in corporate infrastructures, therefore the security related issues has also increased to a   drastic level. The purpose of Wi-Fi is to hide complexity by enabling wireless access to applications and data, media and   streams. The main aims of Wi-Fi are the following:
   • Make access to information easier
   • Ensure compatibility and co-existence of devices
   • Eliminate cabling and wiring
   • Eliminate switches, adapters, plugs, pins and connectors.
   • Typically reducing the costs of network deployment and expansion.

What are the threats with Wi-Fi?

  Wi-Fi networks that are open can be monitored and used to read and copy data (including personal information)   transmitted   over the network. Some of the prominent threats of Wi-Fi are:-
   • Evil Twin
   • War Driving
   • Promiscuous Clients

About WI-Fi Security Systems?

  The contribution of Micro Technologies has been significant in security domain be it a personal asset security or cyber security. Micro Wi-Fi Security System (WSS) is software which works in the stealth mode.Micro Wi-Fi Security System (WSS) installed in the computer, allows the administrator to monitor the activity of the user and provide information about the Wi-Fi access through the authorized web account.

    • Micro WSS automatically detects the change of security settings and warns the Wi-Fi user and send the details on to the Server level Secured Web Account of the user to prevent an Evil Twin and Promiscuous Clients attack.
    • In an unsecured/secured WLAN, Micro WSS can detect any addition of a user and can send an alert email containing the information about the new machine. The email will contain the following information:
      a. IP address assigned to the machine
      b. MAC address of the user

    • Using MAC address the user can be identified and the location of the user can be traced.

Steps to protect your Wi-Fi network?
    • Change the default password: Default passwords for popular routers and access points are easy to find online, so therefore, it is essential that you change the default password as soon as you install a WiFi device. To do so, launch your wireless hardware's setup software and enter a new password.
    • Change the default SSID: Change the default SSID, which is your network's name. Load your router's setup software, look for the SSID name and change it to one that doesn't describe your location or other personal info.
    • Disable SSID broadcast: By default, your Wi-Fi network broadcasts its name to all wireless users within range. With broadcast disabled, your network is invisible to your neighbours.
    • Activate encryption: Go to Start/Control Panel/Wireless Network Setup Wizard. If this is a new Wi-Fi LAN, check "Set up a new wireless network." Enter SSID and complete Network Setup Wizard.
    • Use MAC address filtering: Use MAC address filtering to create a list of devices that can access your network or PC. To determine what your MAC address is, select Start/Run and type cmd and then ipconfig/all on the command line. Hit Enter. The "Physical Address" is your MAC address.
    • Enter MAC address into network software:The MAC address you found in the previous step can be added to a select list of devices that can access your LAN. This is done in your router's setup software (if MAC address filtering is supported).
    • Enable Firewalls On Each Computer and the Router: Modern network routers contain built-in firewall capability, but the option also exists to disable them. Ensure that your router's firewall is turned on. For extra protection, consider installing and running personal firewall software on each computer connected to the router.
    • Assign Static IP Addresses to Devices: Most home networkers gravitate toward using dynamic IP addresses. DHCP technology is indeed easy to set up. Unfortunately, this convenience also works to the advantage of network attackers, who can easily obtain valid IP addresses from your network's DHCP pool. Turn off DHCP on the router or access point, set a fixed IP address range instead, then configure each connected device to match. Use a private IP address range (like 10.0.0.x) to prevent computers from being directly reached from the Internet.
    • Do Not Auto-Connect to Open Wi-Fi Networks: Connecting to an open Wi-Fi network such as a free wireless hotspot or your neighbor's router exposes your computer to security risks. Although not normally enabled, most computers have a setting available allowing these connections to happen automatically without notifying you (the user). This setting should not be enabled except in temporary situations.
    • Turn Off the Network During Extended Periods of Non-Use
How To secure your Wireless Network?

The following pages briefly describe the procedures to implement wireless network security good practices on the most common access points available today viz. Netgear, Linksys and D-Link. You are strongly encouraged to refer to the manufacturer’s user guide for your access point.
