What does a Package Manager Do?

  • Installs packages / modules / gems (called it what you want)
  • Pre-/Post-Installs
    • How often have you looked into the pre-/post-install hooks?

How to protect yourself and your clients?

  • reading, reading, reading, ... :( 
  • Support one of the security projects
  • Implement "scanners" / virtual testing machines
    • one of my little side projects
  • or use private repository
    • private-repo-as-a-service gemfury
