More tips for safe mobile computing03 November 2005
If you're regularly out of the office, the option to access your computer files and the Internet can be extremely useful. Whether you have a spare half-hour on the train, are at a conference in another country, or are taking a break from the office in a coffee shop, there are a number of options you can explore for speedy, secure remote access to the web.
There are two ways in which you can access the Internet remotely:
- Via a wireless local area network (WLAN), which can offer a fast connection but is limited to areas where there is a wireless hotspot.
- Through a GPRS connection with your mobile phone provider, which you can use with a laptop or other mobile device.
In either case, you'll need to ensure you follow a few tips to help ensure your computer and data is safe from hackers and viruses that target wireless networks. Try the following as a starting point:
- Install a firewall. This helps to block unauthorised users from gaining access to your computer through either a network or the Internet. It can screen for incoming viruses, as well as checking other information coming from the network or Internet. BT's Internet Security Pack contains a fully featured firewall combined with antivirus software on a monthly rental basis.
- Password-protect your files - and use a random password-generating tool such as the WinGuides.com Password Generator. This generates a password that incorporates a random selection of letters and numbers, and is more secure than simply using a memorable name, place or date, which can be easily guessed.
- Disable file and printer sharing options. These settings allow other users on a network to access resources on your computer and, when you're working at a wireless hotspot, having them on can leave your computer vulnerable to hackers. This guide provides step-by-step instructions on how to disable these settings.
- Turn your connection off when it's not in use. An open connection is risky and can be vulnerable to hacking. It is considered good practice to ensure the connection is switched off as soon as it is no longer being used.
- There are particular risks for users of Bluetooth-enabled mobile devices, because hackers can gain access to these devices through a process known as 'bluesnarfing'. The Bluetooth website offers further explanation and tips on avoiding this type of e-crime.
