Ensure rcnfs service is not in use

中レベル 1自動aix

説明

The rcnfs entry starts the NFS, NIS and automount daemons during system boot. Additionally, it automounts filesystems with the attribute vfs = nfs. NFS is a service with numerous historical vulnerabilities and should not be enabled unless there is no alternative. Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.

修正方法

修正方法: ガイダンスまたは IaC パッチ

Use the chitab command to disable the NFS start-up script in /etc/inittab: Note: Do not use the rmitab to remove the NFS start-up script from /etc/inittab as it may return during a update. chitab "rcnfs:23456789:off:/etc/rc.nfs > /dev/console 2>&1 # Start NFS Daemons" Also, to be certain NFS and NIS related services have been stopped - execute the following script: /etc/nfs.clean
