5 Ways to Improve Your Wireless Security
Information technology (IT) professionals have become some of the most sought after employees in today’s tech-savvy environment. Many organizations are utilizing wireless networks, but ensuring they’re safe from hackers and unauthorized users isn’t always easy. Limiting who has access to the network and how far your signal reaches is important, but there are a few other tips to help keep it secure.
The use of mobile devices is making security even more difficult and IT employees have to go the extra mile to make sure their networks remain protected. For businesses looking to enhance their wireless security, consider implementing some of the following suggestions.
Develop a Policy
In order for a network to remain completely secure, all employees need to be educated about safe practices. Not everyone is aware that a poor password or sharing information between employees can jeopardize security.
IT professionals should specify the type of network activities that are allowed and which ones aren’t. Antivirus software should also be installed to protect against viruses. Employees should also be taught about what makes a strong password and the importance of not sharing it even with other coworkers. A remote access policy should also be established if workers are able to access the network outside the office.
Secure Your Router
Most routers are given an administrative password to log in and modify settings. Unfortunately these default passwords are weak – sometimes using the company name as the password. One of the first steps of setting up your WLAN should be to change the default password to something only you would think to use. Like all of your passwords you should write it down and keep it in a safe place in case you don’t remember it.
Limit Remote Administration
WLAN routers can be administered remotely through the internet, but experts recommend using this feature carefully. Remote access should only be available if you can limit its range and define specific IP addresses that can access it. Otherwise just about anyone could access your router from any location.
Lower the WLAN Transmitter Power
Some wireless routers allow you to reduce the power of your WLAN transmitter. Doing so limits the range of the signal and thus limits the opportunity for hackers nearby to access it. Your signal should cover the parameters of your business and nothing more.
Hide Your Service Set IDentifier
Your networks name is continually broadcasted and this only makes it easier for hackers to locate and attack your network. Don’t make it convenient for others to find you. You should turn off the Service Set IDentifier (SSID) broadcast option to make your network invisible to neighbors and people nearby.
Once again it’s important to include your employees in your effort to maintain the security of your network. Without proper education most employees are probably completely unaware of the risks and the things that can compromise a network. If you’re a business without an IT professional on staff, consider hiring one or at least contact an IT support company so you know you’re fully protected.
