Security is the Basis of Privacy

According to wikipedia:

“Security is freedom from, or resilience against, potential harm (or other unwanted coercive change) caused by others.”
“Privacy is the ability of an individual or group to seclude themselves, or information about themselves, and thereby express themselves selectively.”

So what are the differences? Which is more important? And why how are they related?

Well a high security mansion with the latest systems would be very secure, but it would not be very private, while a shack in the woods in the middle of no-where may not be very secure, it is very private.

Bracack Obama once said “You can't have 100% privacy and 100% security at the same time.”. Now while I'd love to disagree this is probably quite accurate. You are (on the whole) more secure as a group of people than on your own, and by being with other people you are less private than you are on own.

Finding the gap between privacy and security can be hard, and so I am going to try to make it a bit easier.

Encrypt everything. Never visit a page that is unencrypted (i.e. does not have https), it would be a good idea to install HTTPS Everywhere. Make sure all you files are encrypted using a reliable encryption software. Make sure all communications are end to end encrypted by using an reliable encrypted messenger. Not only is encryption good practice for privacy it is also good for security.

Make a conscious effort to replace your everyday online services with open source alternatives. However just because something is open source this does not always mean it is more secure. Rather it means you are (probably) relying on other people (this could be literally anyone) to have checked the code. This may sound bad but its better than relying on a few developers from a huge company not known for privacy. If you are struggling to find alternatives use one of these tools.

It is also important when choosing hardware to look at the security chips etc... The Google Pixel 3a has the Titan M security chip, and if you installed GrapheneOS then it would also become very privacy respecting.

At the end of the day, privacy and security are equally important as they pretty much go hand in hand. However the challenge is to find the right balance.
