/etc/asl/configfile using the vi text editor. -
Increase the value for the

Execute the command below to update the rulesets:
# for i in daily weekly monthly; do /usr/local/psa/bin/sw-engine-pleskrun /usr/local/psa/admin/plib/DailyMaintainance/script.php -f UpdateModSecurityRuleSet --period "${i}"; done
This way the change will remain persistent after any updates/rulesets changes.
