iX workshop: hardening Linux servers with encryption and access control

Summary

In 2026 heise again advertised the five-day iX workshop “Hardening Linux servers” with Florian Winkler of B1 Systems, this time with dates in September and November. Topics range from physical security through encryption, two-factor authentication and SELinux/AppArmor to logging, monitoring and intrusion detection. The target group is Linux administrators and security officers who want to secure their servers systematically.

Ideas

  • Systematic hardening covers access, encryption, logging and detection together.
  • Practical exercises on real systems anchor knowledge better than theory.
  • Small groups leave room for questions about your own infrastructure.

Insights

  • That the same workshop recurs every year shows the continuing need for the basics of server hardening.
  • Hardening is not a one-off project but part of ongoing operations.

Facts

  • The dates were 21 to 25 September and 9 to 13 November 2026.
  • The number of participants was limited to twelve.

References

Critique

  • As promotional text, the report offers no insight of its own beyond the list of topics.

Remarks

  • This post deliberately sits alongside the 2025 workshop notice: the topics have hardly changed.

Recommendations

  • Use benchmarks such as the CIS recommendations as a structured starting point for your own hardening.
  • Check hardening measures regularly with tools such as Lynis.

Linux 4.13: kernel handles TLS encryption itself

In 2017 Linux 4.13 was able to take over the encryption and decryption of a TLS connection itself for the first time. This was meant to improve performance and open up new uses. The complex connection setup, however, is still handled by libraries such as OpenSSL in user space.

c’t Linux 2015: securing servers and long-term Linux distributions tested

The special issue c’t Linux 2015 brought together guides to securing servers and a comparison of ten distributions with long-term support. Further topics were Linux containers, Btrfs as the default file system, console tools and the X11 successor Wayland. In addition there was KDE Plasma 5, a comparison of mail clients and a DVD with eight distributions.
