Standard Linux permissions like chmod cannot stop the root user from accidental deletions or malicious overwrites. Filesystem-level attributes via chattr and lsattr solve this by enforcing immutable (+i) and append-only (+a) flags directly at the ext4 and xfs inode layers. Learn how to inspect, modify, and audit advanced Linux file attributes for immutable security and audit logging. #Linux #SysAdmin #Cybersecurity #DevOps #SRE #LinuxSecurity #FileSystem #Bash #Hardening #SecOps
