Ensure msdosfs kernel module is not available

SedangLevel 1Otomatisfreebsd

Deskripsi

The msdosfs driver will permit the FreeBSD kernel to read and write MS-DOS based file systems. Removing support for unneeded file system types reduces the local attack surface of the system. This module is required only when reading or writing from MS-DOS based filesystems such as FAT16 or FAT32 file systems. Audit: `kldstat -q -m msdosfs` must report the module is not loaded.
