Find Files and Directories with Extended Attributes

MediaNivel 1Automatizadasolaris

Descripción

Extended attributes are implemented as files in a "shadow" file system that is not generally visible via normal administration commands without special arguments. Attackers or malicious users could "hide" information, exploits, etc. in extended attribute areas. Since extended attributes are rarely used, it is important to find files with extended attributes set. Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.
