Linux advanced performance and security

This course dives deeply in Linux performance tuning, explains how to optimise your systems and build high-performance best practices. It explains which tools and how to best analyse performance related problems and how to build Linux clusters. It continues with an extensive look in the most important security tools and methods to harden your Linux infrastructure.

At the end of the course, the students will understand Linux better, in following domains :

  • Performance tuning concepts
  • Performance tuning tools
  • Understand important misconceptions related with performance tuning
  • Kernel tuning
  • Understand best practices
  • Gain working experience with clustering architectures
  • Can apply clustering with LVM and Ultramonkey
  • Virtualisation
  • Understand the different angles involved with hardening of a system
  • Gain working experience with file integrity checkers and different implementations
  • Understands the concept of openssh proxy-ing
  • Becomes experienced with tools such as nmap, iptables and many more...
  • Is able to set up the Snort Intrusion Detection System with it's web interface ACID and mySQL backend.
