Secrets from The Dark Side of the Web

What this episode covers

The interconnected world of today has made living our lives and running our businesses a lot more straightforward. Keeping up with international clients, monitoring cash flow and sharing ideas with colleagues are just some of the business activities that can be handled at the touch of a button. However, as we become more connected, we are also becoming more vulnerable. Protecting ourselves and our businesses needn’t take up too much of our time and can start with some basic steps. For example, how many times have you been to a café and connected to their open Wi-Fi without giving it a second thought? I know I’ve done that more times that I can remember. Connecting to an unencrypted, public Wi-Fi network is a potentially dangerous thing to do as an attacker within reception range of the router can insert themselves as a ‘man-in-the-middle’, receiving your data without you even noticing. E-mails, banking information, passwords and whatever else you have stored in your phone could be accessed using this method. If you’re using an unencrypted public Wi-Fi, don’t use your phone for anything sensitive. It’s much safer to use an encrypted network which is one requiring a password. If you can use a VPN (virtual private network) at the same time, then even better. Keeping the software on your personal computer and any other machines used for business is another simple and effective way to combat malicious attacks. Every time you receive a notification to update something, there is a good reason to do so. Usually patches and updates are a response to a vulnerability or exploit that has been found and could be used to gain access to a system. Malicious attackers target those who haven’t updated their software because they can use these vulnerabilities to gain access to their systems. So, next time you see a notification alerting you that it’s time to update, update! Another great way to keep things secure is to choose your passwords wisely. Hackers can use vast online dictionaries to brute force their way into systems and accounts. The entries in these dictionaries number into the hundreds of millions and sophisticated algorithms can go through them all in a matter of minutes. Therefore, however obscure your password, there is a good chance that part of it features in one of these dictionaries. The key then, is to use a password that couldn’t possibly feature in one. Gobbledegook, long strings of words joined together or memorable nonsense are all good ways to select a password. Use a service like Last Pass, and you’ll only need to regularly remember one password to access all your favourite sites.
