How Linux Access Control Lists Secure Multi-Tenant Environments

Episode 53 of The Linux Podcast with Fexingo dives into Linux Access Control Lists (ACLs) — the overlooked permission system that goes beyond traditional Unix chmod for multi-tenant servers. Lucas explains how ACLs let you grant specific users read, write, or execute permissions on a per-file basis, using examples like a shared log directory where a DevOps team needs write access while auditors get read-only. Luna brings up production horror stories where ACLs saved them from building custom workarounds. The episode covers the getfacl and setfacl commands, ACL mask semantics, and how NFSv4 ACLs differ from POSIX. A concrete look at a tool every sysadmin should master. #Linux #AccessControlLists #Sysadmin #MultiTenant #Security #OpenSource #Technology #POSIXACL #NFSv4ACL #getfacl #setfacl #ServerSecurity #LinuxPermissions #DevOps #Infrastructure #FexingoBusiness #BusinessPodcast #TheLinuxPodcast Keep every episode free: buymeacoffee.com/fexingo
