Security

  1. PureOS allows for a safer and more secure use and web browsing experience than non-free operating systems like those found on Apple, Google or Microsoft devices.

  2. PureOS does not track or log your keystrokes, location, software usage by default; these services are all opt-in.

  3. PureOS has app isolation with Wayland and AppArmor enabled, as well as security oriented default configurations.

General security recommendations

  • Update software regularly: Regularly update your operating system and all installed applications. This includes security patches and updates for the PureOS operating system and any software you use.

  • Use strong passwords: Ensure that you use strong, unique passwords for all accounts. Consider using a password manager to help manage and generate secure passwords.

  • Enable Full Disk Encryption: If not already enabled, consider using full disk encryption to protect your data in case of theft or loss.

  • Configure a firewall: Ensure that a firewall is enabled to protect your system from unauthorized access. PureOS typically includes a firewall that can be configured.

  • Install antivirus software: While Linux systems are generally less susceptible to viruses, it’s still a good idea to have antivirus software installed (such as clamav daemon or the clamtk graphical tool) to protect against malware and other threats.

  • Take caution with downloads: Only download software from trusted sources. Verify the integrity of downloaded files using checksums or signatures when available.

  • Enable Two-Factor Authentication (2FA): Enable 2FA on accounts that support it for an additional layer of security.

  • Create regular backups: Implement a regular backup strategy to ensure that your data is safe. Use external drives or cloud services to back up important files.

  • Secure your network: Use a secure Wi-Fi connection with WPA2 or WPA3 encryption if possible. Avoid using public Wi-Fi for sensitive transactions without a VPN.

  • Monitor system logs: Regularly check system logs for any unusual activity that could indicate a security breach.

Viruses and malware

The Linux kernel and GNU-based operating systems are significantly resistant to viruses and malware. PureOS can protect your device from viruses, malware and cryptolockers.

Consider installing the following software for additional protection, which are provided free-of-cost and require negligible input from the user:

  • ClamAV, an anti-virus and malware protection tool

  • Uncomplicated Firewall (ufw), which helps to keep you secure by securely managing connections to your computer

Additional security frequently comes at the cost of convenience, and you should balance these needs with your use-case. If you are dealing with many files from untrustworthy sources and sharing some with others, then it is recommended to use ClamAV to prevent accidental sharing of malware and viruses via internet or portable memory drives, even though it cannot harm your system. If you intend to use services which are opened to the outside world, like ssh, web or ftp server, etc. on your computer, then it is recommended to use a simple firewall.
