  • Develop a process for applying updates to systems including verifying properties of the update.
  • Create file systems
  • Allocate an advanced file system layout and use file system encryption.
  • Manage file systems

  • Configure software to monitor the files on your machine for changes.
  • Manage user accounts
  • Set password-aging properties for users; audit user accounts.
  • Manage pluggable authentication modules (PAMs)

  • Install central authentication
  • Install and configure a Red Hat Identity Management server and client.
  • Manage central authentication
