Since linux is more secure, but not 100% secure, what are programs I should install to make my system even more secure?

This page summarizes the projects mentioned and recommended in the original post on /r/linux4noobs

  • InfluxDB - Power Real-Time Data Analytics at Scale
  • WorkOS - The modern identity platform for B2B SaaS

  • firejail

    Linux namespaces and seccomp-bpf sandbox

  • Use some sandbox application like firejail.

  • src

    Read-only git conversion of OpenBSD's official CVS src repository. Pull requests not accepted - send diffs to the tech@ mailing list.

  • If you really really want to clamp down on security and make an impenetrable fortress computer, look into installing OpenBSD, which is not Linux, but still a UNIX-like operating system and is widely acknowledged to be the most secure FOSS UNIX-like operating system.

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  • BorgBackup

    Deduplicating archiver with compression and authenticated encryption.

  • For the backup I use Borg and the backups are stored on external hard drives and at rsync.net. Encrypted in all cases.

  • borgmatic

    Simple, configuration-driven backup software for servers and workstations

  • Borgmatic would be an additional script for Borg that extends the range of functions.

  • restic

    Fast, secure, efficient backup program

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
