EncFS
EncFS is a Free (LGPL) FUSE-based cryptographic filesystem. It transparently encrypts files, using an arbitrary directory as storage for the encrypted files. Two directories are involved in mounting an EncFS filesystem: the source directory, and the mountpoint. Each file in the mountpoint has a specific file in the source directory that corresponds to it. The file in the mountpoint provides the unencrypted view of the one in the source directory. Filenames are encrypted in the source directory. Files are encrypted using a volume key, which is stored either within or outside the encrypted source directory. A password is used to decrypt this key. EncFS has been declared dormant with no further updates by Valient Gough, the developer, on its Github page in May 2024. They recommend using gocryptfs instead. Common uses * In Linux, allows encryption of home folders as an alternative to eCryptfs. * Allows encryption of files and folders saved to cloud storage (Dropbox, Google Driv ...

ECryptfs
__NOTOC__ eCryptfs (''enterprise cryptographic filesystem'') is a package of disk encryption software for Linux. Its implementation is a POSIX-compliant filesystem-level encryption layer, aiming to offer functionality similar to that of GnuPG at the operating system level, and has been part of the Linux kernel since version 2.6.19. Details The eCryptfs package has been included in Ubuntu since version 9.04 to implement Ubuntu's encrypted home directory feature, but is now deprecated eCryptfs is derived from Erez Zadok's Cryptfs. It uses a variant of the OpenPGP file format for encrypted data, extended to allow random access, storing cryptographic metadata (including a per-file randomly generated session key) with each individual file. It also encrypts file and directory names which makes them internally longer (average one third). The reason is it needs to uuencode the encrypted names to eliminate unwanted characters in the resulting name. This lowers the maximum usable byte na ...

Cryptographic Filesystem
Filesystem-level encryption, often called file-based encryption, FBE, or file/folder encryption, is a form of disk encryption where individual files or directories are encrypted by the file system itself. This is in contrast to the full disk encryption where the entire partition or disk, in which the file system resides, is encrypted. Types of filesystem-level encryption include: * the use of a 'stackable' cryptographic filesystem layered on top of the main file system * a single ''general-purpose'' file system with encryption The advantages of filesystem-level encryption include: * flexible file-based key management, so that each file can be and usually is encrypted with a separate encryption key * individual management of encrypted files e.g. incremental backups of the individual changed files even in encrypted form, rather than backup of the entire encrypted volume * access control can be enforced through the use of public-key cryptography, and * the fact that cryptographic k ...

FUSE (Linux)
Filesystem in Userspace (FUSE) is a software interface for Unix and Unix-like computer operating systems that lets non-privileged users create their own file systems without editing kernel code. This is achieved by running file system code in user space while the FUSE module provides only a bridge to the actual kernel interfaces. FUSE is available for Linux, FreeBSD, OpenBSD, NetBSD (as puffs), OpenSolaris, Minix 3, macOS, MorphOS (as filesysbox.library), and Windows. FUSE is free software originally released under the terms of the GNU General Public License and the GNU Lesser General Public License. History The FUSE system was originally part of ''AVFS'' (''A Virtual Filesystem''), a filesystem implementation heavily influenced by the translator concept of the GNU Hurd. It superseded Linux Userland Filesystem, and provided a translational interface using in libfuse1. FUSE was originally released under the terms of the GNU General Public License and the GNU Lesser Gener ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Two-factor Authentication
Multi-factor authentication (MFA; two-factor authentication, or 2FA) is an electronic authentication method in which a user is granted access to a website or Application software, application only after successfully presenting two or more distinct types of evidence (or Authentication#Authentication factors, factors) to an authentication mechanism. MFA protects personal data—which may include personal identification or financial assets—from being accessed by an unauthorized third party that may have been able to discover, for example, a single password. Usage of MFA has increased in recent years. Security issues which can cause the bypass of MFA are #Fatigue attack, fatigue attacks, phishing and SIM swap scam, SIM swapping. Accounts with MFA enabled are significantly less likely to be compromised. Authentication factors Authentication takes place when someone tries to log into a computer resource (such as a computer network, device, or application). The resource requires ...

Mount (computing)
Mounting is a process by which a computer's operating system makes Computer file, files and Directory (computing), directories on a Computer data storage, storage device (such as Hard disk drive, hard drive, CD-ROM, or network share) available for users to access via the computer's file system. In general, the process of mounting comprises the operating system acquiring access to the storage medium; recognizing, reading, and processing file system structure and metadata on it before registering them to the virtual file system (VFS) component. The location in the VFS to which the newly mounted medium was registered is called a "mount point"; when the mounting process is completed, the user can access files and directories on the medium from there. An opposite process of mounting is called unmounting, in which the operating system cuts off all user access to files and directories on the mount point, writes the remaining queue of user data to the storage device, refreshes file sys ...

Optical Disc
An optical disc is a flat, usuallyNon-circular optical discs exist for fashion purposes; see shaped compact disc. disc-shaped object that stores information in the form of physical variations on its surface that can be read with the aid of a beam of light. Optical discs can be reflective, where the light source and detector are on the same side of the disc, or transmissive, where light shines through the disc to be detected on the other side. Optical discs can store analog information (e.g. LaserDisc), digital information (e.g. DVD), or store on the same disc (e.g. CD Video). Their main uses are the distribution of media and data, and long-term archival. Design and technology The encoding material sits atop a thicker substrate (usually polycarbonate) that makes up the bulk of the disc and forms a dust defocusing layer. The encoding pattern follows a continuous, spiral path covering the entire disc surface and extending from the innermost track to the outermost track ...
