Wi-Fi is integral to a business as it provides access to the Internet for your entire company, including those at computers – without wires cluttering up the space and those on laptops – allowing them to work freely around the office.
However, it is imperative that your network is secure, because if it isn’t you are throwing the door wide open to hackers – putting your business documentation at risk! No one is safe from this; a range of companies have already fallen victim to hackers, including multinational firms such as Sony.
Wi-Fi is one of the easiest ways for hackers to gain access to your business, much easier than you may think! In fact, hacking unsecure Wi-Fi ‘is child’s play’, according to the results from an experiment conducted using public Wi-Fi, by online privacy and security firm HideMyAss! The firm asked a seven-year-old to hack a network, which after watching a video tutorial, took a mere ten minutes and 54 seconds to infiltrate.
Although this experiment was conducted using public Wi-Fi, the premise is the same if your company Wi-Fi is unsecure. It is also important to note that staff working on portable devices, shouldn’t use public Wi-Fi. Hackers can set up a fake Wi-Fi network that looks official, and then simply take your data once you are connected.
But, how can you ensure your Wi-Fi and therefore your business documentation is safe?
If your current password is ‘password’ or ‘12345’, or you simply haven’t changed the default one, change it immediately! The longer and more complicated the password, the harder it will be for hackers to gain access. It is also a good idea to change this regularly and not use the same password across many different services.
Use WPA2 encryption
Turn your wireless router’s encryption on. Avoid WEP encryption as it can be cracked in minutes. Use WPA2, which introduces a new AES-based encryption for better security.
Use a complex passphrase
There aren’t many known weaknesses with WPA2, however it is susceptible to attacks when used with a simple passphrase. The ideal phrase would use at least 25 characters including a mix of upper and lower case letters, numerals and symbols.
If your Wi-Fi router supports Wi-Fi Protected Setup (WPS) you need to disable it. Created as a way for users to add new devices to their network, the WPS pin is an 8-digit number printed in the label of WPS-enabled devices. However, this is susceptible to brute force – with hackers being able to crack the code of vulnerable devices in as little as four hours. This would then allow them to recover your passphrase and make changes to your hardware.
Set up a guest network
Don’t allow visitors access to your private Wi-Fi network. If you want to be able to offer guests wireless Internet access, use one that is segregated from your company’s main network, so they can’t get into your computer or files or see your traffic.
As secure as your Wi-Fi network is, you may want to consider document storage for your really sensitive data. With business documentation, not only could it getting into the wrong hands, causing embarrassing and costly issues for your company, but there are is data protection legislation to comply with. Services such as Kelly’s Document Shredding will also ensure that you are aware of review dates, at which point you will be able to change the date or request its secure destruction.
