Why Data Security Matters#
Ever had one of those moments where you realize your data could have been better protected? That’s exactly what happened to me the other day. I was going through some old files and came across a bunch of sensitive documents that I never thought twice about storing in plain sight.
Basic Steps for Beginners#
Use Strong Passwords: This seems obvious, but it’s amazing how many people still use simple passwords or reuse them across multiple sites.
- I started by using a password manager like LastPass only a self-hosted version called Vaultwarden, to generate and store strong, unique passwords for each of my accounts.
Enable Two-Factor Authentication (2FA): It adds an extra layer of security that’s surprisingly easy to set up and use.
- For most of my important accounts, I enabled 2FA using authenticator apps like Google Authenticator or Authy.
Regular Backups: Make sure you have a backup system in place, whether it’s cloud storage or an external hard drive.
- I started backing up my critical files to a NAS (Network Attached Storage) solution then encrypting and storing the files on Google Drive.
IMPORTANT: The Golden Rule of Data Hygiene
The 3-2-1 Method:
- Three copies of all your data
- Two different types of storage media (External hard drives + NAS)
- One kept off site (S3 Storage recommended, but Google Drive or similar will work fine as long as you encrypt it)
Real-World Examples#
Remember the Equifax breach? That was a wake-up call for many people who thought their data wasn’t at risk. It’s not just big companies; your personal data is valuable too.
Moving Forward#
So, what can you do today? Start by setting up strong passwords and 2FA on all your important accounts. And don’t forget to back everything up regularly.
