Although XML Encryption can be used to encrypt any kind of data, it is nonetheless known as "XML Encryption" because an XML element (either an EncryptedData or EncryptedKey element) contains or refers to the cipher text, keying information, and algorithms.
The Encrypting File System (EFS) on Microsoft Windows is a feature introduced in version 3.0 of NTFS [1] that provides filesystem-level encryption.The technology enables files to be transparently encrypted to protect confidential data from attackers with physical access to the computer.
Historically, various forms of encryption have been used to aid in cryptography. Early encryption techniques were often used in military messaging. Since then, new techniques have emerged and become commonplace in all areas of modern computing. [1] Modern encryption schemes use the concepts of public-key [2] and symmetric-key. [1]
VeraCrypt is a free and open-source utility for on-the-fly encryption (OTFE). [5] The software can create a virtual encrypted disk that works just like a regular disk but within a file.
If the user does enable macros, they save and run a binary file that downloads the actual encryption Trojan, which will encrypt all files that match particular extensions. Filenames are converted to a unique 16 letter and number combination. Initially, only the .locky file extension was used for these encrypted files.
ils lists all metadata entries, such as an Inode. blkls displays data blocks within a file system (formerly called dls). fls lists allocated and unallocated file names within a file system. fsstat displays file system statistical information about an image or storage medium. ffind searches for file names that point to a specified metadata entry.
CryptoLocker typically propagated as an attachment to a seemingly innocuous email message, which appears to have been sent by a legitimate company. [5] A ZIP file attached to an email message contains an executable file with the filename and the icon disguised as a PDF file, taking advantage of Windows' default behaviour of hiding the extension from file names to disguise the real .EXE extension.
Because of its nature data at rest is of increasing concern to businesses, government agencies and other institutions. [4] Mobile devices are often subject to specific security protocols to protect data at rest from unauthorized access when lost or stolen [7] and there is an increasing recognition that database management systems and file servers should also be considered as at risk; [8] the ...
