Modern laptops provide an amazing means of working or playing from just about anywhere in the world. But they also tend to be valuable repositories of sensitive information. The details of your finances, your working arrangements, or your personal life might be stored on your laptop. If you don’t take steps to protect it against malware, phishing, and other threats, then you could end up vulnerable.
Use Strong Passwords and Enable Multi-Factor Authentication
A strong password is one that’s difficult to guess. More specifically, it should be difficult for a brute-force algorithm to break through. That means employing a unique combination of numbers, letters, and special characters. Don’t be tempted to recycle passwords across several different accounts; if you do, then you run the risk of a data breach leaking many different passwords instead of just one.
A good password manager provides a means of composing and storing unique passwords for every service you use. Many of the good ones are free.
You’ll also want to protect very sensitive logins through multi-factor authentication. This means that you’ll be submitting not just a password (something that you know), but also that you’ll need access to a device like a mobile phone (something that you have) and to submit a biometric marker, like a fingerprint scan (something that you are).
The combination of these three things makes it much, much more difficult for a would-be intruder to gain access.
Keep Your Operating System and Security Software Updated
No software is perfect. Vulnerabilities are constantly being uncovered, and developers are constantly racing to address them through patches. By keeping your software up to date, you’ll benefit from these additional protections.
Operating systems are particularly important in this regard. Set up automatic updates, and pick an OS that comes with the right built-in security tools.
Protect Your Laptop on Public Wi-Fi and While Traveling
If you’re regularly logging into public Wi-Fi networks – perhaps on a train, or in a cafe – then you’ll need to take extra precautions. Can you be sure that you’re logging onto a genuine network, and not a fake one with a misleading name? Who else is connecting to the network, and might you be at risk of a man-in-the-middle attack?
Government security guidance recommends that we exercise extreme caution when using these networks. A free VPN for Mac or Windows might be a great first step – but you might equally simply avoid submitting sensitive information through a network of this kind.
Prevent Laptop Theft and Protect Your Data
The threats faced by your laptop aren’t just digital. They’re also physical. If you’re leaving your device unattended, make sure that it’s locked – and being watched by someone you trust. Regularly back up any files that matter to you, and install tracking tools so that you can follow any thief – and remotely wipe the storage drive.
