access protection

Access protection or access prevention are techniques used to prevent unauthorized access by persons or computers to resources - these can be computers, peripheral devices, memory, data, files, accounts, networks or programs

. Access protection ensures that only authorized individuals have access to these resources. As part of data security

, access protection protects devices, programs, and data from tampering and from unauthorized processing and disclosure. Access protection is based on access control and starts with the operating system, which protects certain files in such a way that they can be viewed but not edited because the editing functions are disabled. On this basis, various Unix variants assign users their own rights for reading (Read, R), writing (Write, W) and executing (Execute, X). As far as user authentication is concerned, password procedures are used here which increase data security.
