Here are four simple steps that will help you stay secure.
1. You: technology alone cannot fully protect you; you are your best defense. Attackers have learned that the easiest way to get what they want is to target you rather than your computer or other devices. If they want your password, credit card, or control of your computer, they’ll attempt to trick you into giving it to them, often by creating a sense of urgency.
Ultimately, the greatest defence against attackers is you. By using common sense, you can spot and stop many attacks.
2. Password: Modern computing speeds have made the old, eight-character password outdated and vulnerable. When a site asks you to create a password, create a strong and unique passphrase instead. A passphrase is a type of password that uses a series of words that is easy to remember, such as “love life to the fullest everything”. The longer your passphrase is, the stronger. A unique passphrase means using a different one for each device or online account. This way, if one passphrase is compromised, all of your other accounts and devices are still safe. Can’t remember all those passphrases? Use a password manager, which is a specialized program that securely stores all your passphrases in an encrypted format (and offers lots of other great features as well).
Finally, enable two-step verification (also called two-factor or multi-factor authentication). It uses your password but also adds a second step, such as entering a code sent to your smartphone or from an app that generates the code for you. Enabling two-step verification is probably the most important step you can take to protect your online accounts, and it’s much easier than you may think.
3. Updating: Make sure each of your computers, mobile devices, programs, and apps is running the latest version of its software. Cyber attackers are constantly looking for new vulnerabilities in the software your devices use. When they discover vulnerabilities, they use special programs to exploit them and hack into the devices you are using.
4. Backups and recovery: No matter how careful you are, you still may be hacked. If that is the case, often the only way to restore all of your personal information is from backup. Make sure you make regular backups of any important information and verify that you can restore your data from them. Most operating systems and mobile devices support automatic backups, either to external drives or to the cloud.
