vulnerabilities every time had been a crucial and lasting so far. So what is the trustable and feasible approach for the purpose of manifesting objectives? Developing file system with cryptographic features can promote liabilities. The Cryptographic File System (CFS) provides a secure and reliable storage by using UNIX file system for encrypting files. Utilizing a key for encrypting and decrypting directories and files (also their pathnames) is usual in any cryptography issue and in this paper we also mention about it. System administration process like backup, establish in a suitable way without knowing about the key. Ability to respond any accessible file system without any modification in order to cover remote servers like NFS is another advantage of CFS. This paper explains the CFS under UNIX briefly which is also applicable in UNIX like system such as Linux.
