Update Your Software
No matter the software is closed source or open source, always keep them up to date, and turn on automatic updates for your operating systems (Windows, macOS, Linux), web browsers (Chrome, Firefox, Brave, etc), and all the installed apps.
Upgrade your OS
Switch to a secure, privacy-friendly and open source operating system that doesn’t track and monetize your usage data.
You can use great operating systems like Qubes OS, Parrot OS, Tails or Whonix that come with lots of perks like compartmentalization, AnonSurf, etc.
Upgrade your Browser
Switch to a secure browser that protects your privacy, and keep your personal data secure while defending you from tracking, fingerprinting, and malicious advertising.
I recommend using secure and open source browsers like Mozilla Firefox, Brave, Tor browser, etc for better privacy and security.
- Utilize the principle of compartmentalization by using different browsers.
- Make sure your browser’s fingerprint is not unique
- Install add-ons for privacy and security.
Upgrade your Search Engine
Switch to a private search engine that doesn’t track your search queries, location, etc and monetize it. Avoid using search on the browser where you are logged in with your online accounts.
I recommend using private search engines like Searx, DuckDuckGo, YaCy, etc that don’t track you.
Upgrade your Password Management
Switch to a secure password manager that can create and store unique passwords for each of the services you use. Do not use your browsers’ built-in password manager to store your passwords.
I recommend you using an open source password manager like Keepass XC or Bitwarden.
At the very minimum, use a strong and unique passwords for each of the high-value accounts like your Google, Apple, Microsoft, Email, Banking, etc.
- Sign up and check for breach alerts on haveibeenpwned.com or Firefox Monitor.
- Use a strong passcode / PIN for your phones.
- Set up a mobile carrier PIN for protection from SIM Hijacking.
Use Two-Factor Authentication
Two-Factor authentication (2FA) protects your accounts even if your password falls into the wrong hands by adding an extra layer of security on top of passwords.
I recommend using open source app-based 2FA like Aegis Authenticator and Authenticator by Matt Rubin.
- Don’t use 2FA via SMS, always choose App-based 2FA or hardware-based 2FA.
- Avoid using your password manager for 2FA as it creates a single point of failure — defeating the purpose of 2FA.
- Make sure your Backup codes are stored in a safe place.
Encrypt your Data
Always encrypt your phones, computers, and wherever you have your data as this adds a layer of protection even if your device is physically stolen.
All the operating systems, be it Windows, macOS, Linux, Android or iOS come with built-in options for encryption.
You can also use free and open source tools like VeraCrypt or 7Zip to encrypt your files.
Use an Encrypted Email
Switch to an encrypted and privacy-friendly email service provider that doesn’t read your email or collect data about your conversations to target you with ads.
I recommend using private and encrypted email providers like Tutonota, ProtonMail, Soverin, etc.
Use an Encrypted Messenger
Switch to a secure, open source, and end-to-end encrypted messaging app as this protects both the authenticity and confidentiality of the messages as they pass through any devices or servers.
I recommend using free and open source messaging apps like Signal, Riot, Session, etc.
Popular messaging apps like iMessage, WhatsApp, Viber, etc are not open source.
Use an Encrypted DNS
DNS or Domain Name Servers are the internet’s equivalent of a phone book, they convert domain names of websites like “google.com” into IP addresses for your browser to connect.
I recommend using an encrypted and private DNS Resolvers like AdGuard DNS, Blah DNS, Cloudflare 188.8.131.52, etc as it will help prevent DNS hijacking, and can block malicious sites, ads, and trackers.
An encrypted DNS Resolver won’t make you anonymous, neither will it hide your internet traffic from your ISP.
Use a VPN
A VPN or a virtual private network encrypts your data preventing people from snooping on your traffic, it also helps you access restricted content.
I recommend using trusted VPN providers like Proton VPN, Mullvad VPN, etc that don’t harvest and re-sell your data as they will be the middlemen between you and the internet.
A VPN won’t make you anonymous, neither will it add any additional security to non-HTTPS traffic.
Review Privacy and Security Settings
Check location, camera, microphone, and other sensitive device permissions on your phone and computer. Make sure you trust apps with sensitive permissions, only allow selective apps permissions to access your calls, messages, camera, microphone, etc.
Check privacy and security settings of your online accounts like Facebook, Twitter, Google, etc, you can use an app like Jumbo Privacy or just go manually.
Backup, Backup, & Backup
Always take backups of your data on a regular basis — use the 3-2-1 golden rule of backups:
- 3 — Keep 3 copies of any important file: 1 primary and 2 backups.
- 2 — Keep the files on 2 different media types to protect against different types of hazards.
- 1 — Store 1 copy offsite i.e. on cloud or somewhere outside your home or business facility
Antivirus, Anti Malware, and Firewalls
Protect your devices from viruses and malware attacks by using a trusted antivirus and anti malware software. You can check out AV-TEST for comparisons.
All the operating systems, be it Windows, macOS, Linux, Android or iOS already have some sort of protection built-in, make sure they are updated.
Use Common Sense
Most of the day-to-day attacks can be prevented by common sense, think before sharing personal information or clicking a link in your email. Keep learning, here are a few tips:
- Install apps from trusted sources and analyze at VirusTotal.com
- Use a webcam cover
- Use a privacy screen to protect yourself from shoulder-surfing.
- Clear cache, cookies, Internet history, temporary files, logs, etc using a privacy cleaner like BleachBit.
- Remove Metadata from photos and other documents before sharing, you can turn off location-tagging in your camera settings.
