Ensure DISCOVER is set to DISABLE

低级别 2自动化db2

说明

DISCOVER=SEARCH lets the instance answer network discovery requests, advertising instances and databases to anyone on the network. Run as the instance owner (or with sqllib/db2profile sourced) so 'db2 get dbm cfg' reads the instance configuration.

检查方式

审计方法: Shell 命令

shell

out=$(db2 get dbm cfg 2>/dev/null) || exit 1; printf '%s\n' "$out" | awk -F= '/\(DISCOVER\)/ {v=$2; gsub(/[ \t]/, "", v); f=1} END {if (f && (v == "DISABLE")) print "compliant"; else print "noncompliant: " v}'

预期输出: compliant
