Security & TLS · pro · solved in-browser (no VM needed) · 3 tiered hints
Write the bash script /home/player/grant-acl.sh (starting with a bash shebang) that uses setfacl to give the 'auditor' user read-and-execute (rX) access to /var/log/app, recursively, AND sets a default ACL so new files inherit that grant. Use two setfacl calls: 'setfacl -R -m u:auditor:rX /var/log/app' and 'setfacl -R -m d:u:auditor:rX /var/log/app'. (Authored config, graded structurally — the engine isn't run here.)
