TMA-TDSQL-3.5
Ensure Correct Permissions on the TDSQL Binary Directory
Description
The binary directory (bin/) contains the executables for all TDSQL components: oss_server, scheduler, startup/shutdown scripts, and Python integration scripts. These files must be protected against unauthorized modification. The benchmark rates this recommendation Manual; the automated check covers its objective pass criterion. Uses TDSQL_HOME (install directory with bin/, conf/, boot/, log/; default /data/tdsql). Counts files that grant the listed permission to other users; any match fails, and a missing directory fails. (o+w). Expected: directory 0750, binaries owned by root:tdsql.
How it is checked
Audit method: Shell command
n=0; for p in "${TDSQL_HOME:-/data/tdsql}/bin"; do [ -e "$p" ] && n=$((n+1)); done; [ $n -gt 0 ] || exit 1; c=0; for p in "${TDSQL_HOME:-/data/tdsql}/bin"; do [ -e "$p" ] || continue; c=$((c + $(find "$p" ! -type l -perm /o+w -print 2>/dev/null | wc -l))); done; echo $c- Expected output
0
How it is fixed
Fix method: Guidance or infrastructure patch
chmod 750 <tdsql>/bin <tdsql>/bin/*; chown root:tdsql <tdsql>/bin <tdsql>/bin/*
