How Enterprises Are Beefing Up Wireless Security

Featured blog by Xander Schofield, Independent Technology Writer

Wireless network is a valuable asset to a business that embraces the technology. It is, indeed, inexpensive and easy to set up and operate. The wireless network has undoubtedly increased enterprises’ performance and productivity. By having a central point of distribution, that entails the installation of a wireless adapter, a business can access the network from any part within the premises. Sharing of documents and hardware components such as printers, scanners, and photocopiers become a very smooth and efficient process. All the clutter and nightmare that comes with physically connecting all the computers and their peripherals is made almost non-existent, except for the few power cable needed here and there.

With such a simplified and efficient means of sharing and communication brought into the business, it would prudent also to know that risks come with such easy access. An insecure wireless network can cause massive damages to the enterprise if hacked and impede some if not all of its operations that rely on network connectivity. Consider the wireless network monitoring best practices below in safeguarding your businesses’ wireless network from unauthorized access.

1. Use WPA2 Encryption

With Wi-Fi signals broadcasting in different directions simultaneously, it is necessary to encrypt your wireless network from neighbors and other malicious individuals looking to invade it. Avoid the use of WEP encryption as it can be brought down in minutes. Using the WPA2 introduces an AES-based encryption for improved security over WAP. WPA2 also enables the business to utilize complex passwords and also filters the MAC address. You can set the password to be 63 characters long, but with at least 25 characters will do.

2. Change the Default Password and Passphrase

During the installation of your wireless network monitoring software, you’ll want to be sure the IT professional or service making the installation understand the potential pitfalls associated with this kind of installation. Things like access point threats, device discovery and wireless client tracking are all “musts”. The changing of your password and passphrase is an especially essential step. For the password, use a combination of characters, numbers and symbols with at least 25 characters long.

3. Disable WPS

Disable the Wi-Fi Protected Setup (WPS) if your router supports it. Designed in a user-friendly way in which users can add devices into the network. The thing is that WPS has an eight digit PIN printed on the label of WPS-liable devices. It is likely susceptible to brute force attacks with a hacker being able to crack the PIN code between four to 10 hours of automated effort. Such an attack will enable the hacker to recover your secret passphrase and make modifications to the Wi-Fi hardware.

4. Establish a Guest Network.

Have a guest network that is accessible to foreign associates, clients and partners are good for business relations. However, having the company’s static passphrase and password handed out to everyone is not proper security practice and can result in hacking and vital data stolen and lost. Instead, set up a different Wi-Fi network under another SSID, a supported feature by an increasing number of adapters. Having this separate network will allow you to change the password routinely without affecting other devices. You can also disable it when not in use.

5. Prevent Administrator Access through the WLAN

Since one with administrative rights can change the router’s configuration, stripping the wireless network of such rights is the safe thing to do. Though this might not directly prevent a hacker from attacking, it will keep them at bay and restrain them from wrecking any further havoc to the business systems.

6. Get Your Employees Involved In Your Company’s Security Policy

Getting your employees know them and understand the company’s security policy is essential. Educating them about the privacy policy, security policy, passwords and problems that may arise from accessing online applications laced with malicious code. Educate them also on how to share safely and connect to networks outside the office. It will keep your business safe from any mishaps that may arise from your employees.

No matter what you do, wireless security investment has a great ROI for organizations and can help you avoid major turmoil.
