Updates for firewalls, operating systems, web browsers and other software packages are released regularly. It is important to stay up to date to ensure that you’re covered against the latest threats and vulnerabilities.
You may not be surprised to learn that one of the easiest ways to transfer files – with USB sticks – is also not very secure. Devices get lost easily, and can be used to steal files or infect computers with malicious software. You should disable USB ports that aren’t needed and consider using encrypted devices if you must transfer files via USB storage.
If your hard drive, laptop, USB stick or mobile phone is stolen or lost, having it’s contents encrypted will make it much harder for anyone to access.
Make sure your password isn’t easy to guess, but is also one that you’ll remember. If you’re stuck for a random password, you might like our Password Generator. Avoid any of the passwords on this list, and try to add symbols, numbers and use a mixture of cases – s0 something along the lines of “my-c@ts-name-is-fluffy76” would be considered fairly strong.
You wouldn’t let anybody just walk into your office and start going through your filing cabinet, so don’t let anybody do this with your network either. Make sure any WiFi networks are secured and if you must offer access to guests, consider using a router that creates an isolated network for them.
If any services or apps that you use support two-factor authentication, you should turn it on. Most banks have been using a form of two-factor authentication with online banking for a while now, and services like Dropbox and Facebook use your mobile phone to generate a one time password. There are also other devices that will work with multiple services, including Yubikey.
