Ensure SUID and SGID files are reviewed

ВысокийУровень 1Ручная проверкаfreebsd

Описание

The owner of a file can set the file's permissions to run with the owner's or group's permissions, even if the user running the program is not the owner or a member of the group. The most common reason for a SUID or SGID program is to enable users to perform functions (such as changing their password) that require root privileges.
