 # File System
 
 ## Disable all file systems not needed
 
-To reduce the attack surface, file system data is parsed by the kernel, so any logic bugs in file system drivers can become kernel exploits.

 ### Disable NFS file system
 
-NFS FileSystems are useful during development phases, but this can be a very helpful way for an attacker to get files when you are in production mode, so we must disable them.
