Your personal security checklist

Recently, I have been exploring areas related to security quite a lot, both in technical and personal matters. I want to share a great list with over 300 different tips on protecting digital security and privacy.

Many things seem obvious. However, I really liked the clear presentation of the topic’s priority, details, and hints. It allows you to see alternatives and understand why a given issue was considered, for example, as recommended.


Using strong passwords is a basic step to being more secure. Using strong, unique passwords for each system in pair with a good password manager will significantly reduce the risk of a brute-force attack or based on disclosed passwords. If you are creating a system, visit the post Check your password security with Have I Been Pwned?. I discussed how you could check for leaks to offer additional security for your clients.

Enable 2-Factor Authentication is also a very important security feature. Most often, support for OTP generated in the application will be offered. Still, sometimes even more secure physical authentication keys (FIDO U2F) can be used. It is worth saving the Backup Codes or registering more than one device to avoid losing access to the system if there is a failure or loss of a 2FA device.

Be careful with any devices you connect to your computer. If you found a USB somewhere, avoid plugging it. You never know what might be on it, and it could be a Fork Bomb attack or some keyloggers.

The same goes for phone calls. Charging via some USB cable in public places, such as a cafe, can end badly. It’s better to use your charger connected directly to the power.

Web browser

Working professionally, the web browser is often an indispensable tool throughout the working day. It is also the first line of defense against dangerous websites. After working for a long time, I started using Brave. It is an excellent combination of the best features offered by Chrome and Firefox. At the same time, security and data protection are strengthened. I recommend this browser to you too!

It would be worthwhile to block ads. In Brave, you have a lot of automatic blockers. However, good Adblock is still recommended. Also, remember to reduce the number of extensions to the necessary minimum. Each extension is a potential danger, so it is worth minimizing the risk.

My friends also use Virtual Machine to open all downloaded files in Sandbox mode. You should consider it as an added security feature when receiving multiple potentially dangerous attachments.

Other recommendations

The list contains many useful recommendations. I only covered the first two chapters by pointing out what it looks like in my life. You do not need to implement all the recommendations, but you should at least read them. Sometimes a tiny change in your daily habits can be of great benefit.

If your friends ask how to keep private data safe, don’t be afraid to recommend this list to them. Maybe this will make us all a little more resistant to attacks.
