Special access rights in Linux are extended access rights that can be set on files or directories and provide additional features or restrictions.
They allow you to manage system privileges and security more precisely than normal access rights (read, write, execute). Also, special access rights in Linux provide special features or restrictions for a user, group, or files. They include the following access rights:
In the Linux system, there are various access rights to files and directories that determine which actions can be allowed or prohibited for a particular user or group of users. The following are the main special file access rights in Linux:
Usually these special rights are specified together with standard access rights (rwx) and are indicated by symbolic or numeric values. For example, setuid is indicated by the symbol "s" instead of "x" for the owner of the executable file.
If you want to set or change special file access rights in Linux, you can use the chmod command with the appropriate arguments. For example, to set "setuid" on an executable file, you can use the command "chmod u+s filename".
Special access rights (SUID, SGID and Sticky bit) can be set on files or directories using the chmod command in Linux.
To install SUID:
chmod +s file_name
To install the SGID on a directory:
chmod +s director_name
To install Sticky bit on a directory:
chmod +t_directory name
Note: It is recommended to restrict the installation of SUID on files, as this may pose a potential threat to the security of the system. Use special access rights with caution and only in situations where it is well-founded and does not create vulnerabilities.
To view the set special access rights, you can use the command `ls -l'. Access rights, including special rights, will be displayed as alphanumeric or numeric values after the access rights to the file or directory.
