File verification is the process of using an algorithm for verifying the integrity of a computer file, usually by checksum. This can be done by comparing two files bit-by-bit, but requires two copies of the same file, and may miss systematic corruptions which might occur to both files.
File integrity monitoring (FIM) is an internal control or process that performs the act of validating the integrity of operating system and application software files using a verification method between the current file state and a known, good baseline.
Configuration Management (CM) is an ITIL-specific ITSM process that tracks all of the individual CIs in an IT system which may be as simple as a single server, or as complex as the entire IT department. In large organizations a configuration manager may be appointed to oversee and manage the CM process.
It is commonly used to verify the integrity of files. It (or a variant) is installed by default on most Linux distributions . Typically distributed alongside sha1sum are sha224sum , sha256sum , sha384sum and sha512sum , which use a specific SHA-2 hash function and b2sum , [ 1 ] which uses the BLAKE2 cryptographic hash function.
This is especially true of cryptographic hash functions, which may be used to detect many data corruption errors and verify overall data integrity; if the computed checksum for the current data input matches the stored value of a previously computed checksum, there is a very high probability the data has not been accidentally altered or corrupted.
Complete integrity check uses cryptographic checksums of files to detect modifications, can find rogue SUID executables anywhere on a disk, and; Centralized monitoring native support for logging to a central server via encrypted and authenticated connections; Tamper resistance database and configuration files can be signed
A software repository, or repo for short, is a storage location for software packages. Often a table of contents is also stored, along with metadata. A software repository is typically managed by source or version control, or repository managers. Package managers allow automatically installing and updating repositories, sometimes called "packages".
