pointed readers toward existing lists and noted the difficulty of finding a “perfect” distro — both answers underline the same practical truth: there is no single unhackable distribution. Choose a distro that matches a clear threat model (server vs. desktop, casual attacker vs. targeted adversary) and validate its operational practices: how fast it ships security fixes, whether packages are signed, what mandatory-access-control it supports, and how small the default attack surface is.

Things to look for when evaluating a distro:

  • Fast, transparent security response and signed packages.
  • Built-in Mandatory Access Control (SELinux, AppArmor) and usable profiles.
  • Minimal/default-install option so you install only what you need.
  • Long-term support channels or a vendor with proven patching practices.
  • Support for full-disk encryption, secure boot, and reproducible builds when available.

Practical, distro-agnostic hardening steps (apply right after install):

  • Install only needed packages and disable unused services.
  • Enable automatic security updates or a monitored update process.
  • Turn on a host firewall and restrict inbound services.
  • Use SSH keys, disable password auth for remote logins, and rate-limit attempts.
  • Use full-disk encryption for sensitive systems and separate user accounts (no daily-root).
  • Add file-integrity and log-audit tools and forward logs to a secure collector.

Example quick commands for Debian/Ubuntu families (adjust for your distro):

sudo apt update && sudo apt upgrade
sudo apt install unattended-upgrades ufw
sudo ufw allow ssh
sudo ufw enable

For tracking CVEs and vendor advisories use the NIST NVD (nvd.nist.gov) and follow hardening benchmarks such as those from CIS (cisecurity.org). For high-assurance desktop isolation consider compartmentalization approaches (see Qubes OS: qubes-os.org).

There's a list of supposedly "secure" Linux distributions here: http://www.linuxlinks.com/Distributions/Secure/ . On the BSD side of things, OpenBSD seems to be the popular one where security is concerned.

Keep in mind though, that no matter how "secure" your operating system claims it is, the weakest link of all security is you as the user. Remember, it's your job to keep updated with the latest security vulnerabilities for the software you use, have a proper firewall in place, and implement proper security policies for the system. You can have all the security in the world in the base system and still have a screwup because of a security hole in an application you installed.
