Ensure Password Reuse Restrictions Are Configured

MediumLevel 2Automatedtdsql

Description

Password reuse restrictions prevent users from reusing recently used passwords when changing their password. Runs the mysql client against the TDSQL data node selected by TDSQL_MYSQL_OPTS (e.g. "-h10.0.0.5 -P4001 -utdsql_audit"); keep the password in ~/.my.cnf or a login path rather than MYSQL_PWD or the command line (see 1.4 and 1.5). Passes when password_history >= 5 and password_reuse_interval >= 365.

How it is checked

Audit method: SQL query

sql_query

out=$(mysql ${TDSQL_MYSQL_OPTS:-} -NBe "SELECT CASE WHEN @@global.password_history >= 5 AND @@global.password_reuse_interval >= 365 THEN 'compliant' ELSE 'noncompliant' END" 2>/dev/null) || exit 1; printf '%s\n' "$out"

Expected output: compliant

How it is fixed

Fix method: Guidance or infrastructure patch

SET GLOBAL password_history = 5; SET GLOBAL password_reuse_interval = 365;
