Wireless network security tips from Pili Mar
In an age dominated by smartphones and tablets, wireless networks have become an increasingly attractive option for many small businesses. With a wireless network, team members can easily collaborate on mobile devices and laptops from anywhere in the office. Employees can join the network or change locations without any wires to manage.
That convenience and portability brings challenges, however, and businesses that choose to go wireless must plan carefully. In addition to some reduction in speed, wireless networks pose an increased security risk. To minimize your risk, consider a few basic tips for wireless network security.
The wireless router directs traffic between the internet and the internal network. The router sends a signal through the air, allowing devices within range to connect to the network. While this is essential in enabling employee access, proper router setup is critical to ensure that hackers within range do not also infiltrate your network.
When setting up and maintaining the router, keep in mind the following:
Any information that passes over the network must be encrypted for safety. Thus, be sure that you turn on encryption when you set up the wireless router. In addition, keep in mind that not all encryption protocols are created equal. Look for a router with WPA2 capability, as this is the strongest encryption protocol. Above all, avoid the outdated and highly vulnerable WEP protocol.
Instead of letting anyone connect to the network as long as they have the correct password, you can limit access to your network to only certain devices. Each device is identified by a unique Media Access Control (MAC) address. Thus, you can configure your wireless router to only allow access to devices with MAC addresses that you specify.
As with any network, wired or wireless, individual users and devices still present the greatest vulnerability. Create and enforce security policies to ensure that the devices that access the wireless network are protected from attack. This includes:
Whether you use a wired network or a wireless network, a defense in depth strategy is essential to keeping critical business data safe from malicious attacks. A single breach of your network can cripple your business with lost productivity, loss of reputation and even legal action.
Increase your wireless network security with proper router setup and strong encryption protocols. Limit access to known devices and implement security policies to maximize mobile device security.
