qmail_tcp_env_selinux(8)
β¨ NAME β¨
okay so this is the qmail_tcp_env_selinux(8) page, and the name line is qmail_tcp_env_selinux β Security Enhanced Linux Policy for the qmail_tcp_env processes. periodt. π
πΈ DESCRIPTION πΈ
Security-Enhanced Linux secures the qmail_tcp_env processes via flexible mandatory access control. no cap.
The qmail_tcp_env processes execute with the qmail_tcp_env_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
For example:
ps -eZ | grep qmail_tcp_env_t
π¦ ENTRYPOINTS π¦
The qmail_tcp_env_t SELinux type can be entered via the qmail_tcp_env_exec_t file type.
The default entrypoint paths for the qmail_tcp_env_t domain are the following:
/var/qmail/bin/tcp-env
π PROCESS TYPES π
SELinux defines process types (domains) for each process running on the system.
You can see the context of a process using the -Z option to ps.
Policy governs the access confined processes have to files. SELinux qmail_tcp_env policy is very flexible allowing users to setup their qmail_tcp_env processes in as secure a method as possible.
The following process types are defined for qmail_tcp_env:
qmail_tcp_env_t
Note:semanage permissive -a qmail_tcp_env_tcan be used to make the process typeqmail_tcp_env_tpermissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. π
π BOOLEANS π
SELinux policy is customizable based on least access required. qmail_tcp_env policy is extremely flexible and has several booleans that allow you to manipulate the policy and run qmail_tcp_env with the tightest access possible.
If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.
setsebool -P fips_mode 1
π FILE CONTEXTS π
SELinux requires files to have an extended attribute to define the file type.
You can see the context of a file using the -Z option to ls.
Policy governs the access confined processes have to these files. SELinux qmail_tcp_env policy is very flexible allowing users to setup their qmail_tcp_env processes in as secure a method as possible.
β STANDARD FILE CONTEXT β
SELinux defines the file context types for the qmail_tcp_env, if you wanted to store files with these types in a different paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk.
semanage fcontext -a -t qmail_tcp_env_exec_t
'/srv/qmail_tcp_env/content(/.*)?'
restorecon -R -v /srv/myqmail_tcp_env_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for qmail_tcp_env:
qmail_tcp_env_exec_tβ Set files with theqmail_tcp_env_exec_ttype, if you want to transition an executable to theqmail_tcp_env_tdomain.
Note: File context can be temporarily modified with thechconcommand. If you want to permanently change the file context you need to use thesemanage fcontextcommand. This will modify the SELinux labeling database. You will need to userestoreconto apply the labels.
π COMMANDS π
semanage fcontextcan also be used to manipulate default file context mappings.semanage permissivecan also be used to manipulate whether or not a process type is permissive.semanage modulecan also be used to enable/disable/install/remove policy modules.semanage booleancan also be used to manipulate the booleans.system-config-selinuxis a GUI tool available to customize SELinux policy settings.
