NAMEftpdctl_selinux − Security Enhanced Linux Policy for the ftpdctl processes
DESCRIPTIONSecurity-Enhanced Linux secures the ftpdctl processes via flexible mandatory access control. The ftpdctl processes execute with the ftpdctl_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 ftpdctl_t
ENTRYPOINTSThe ftpdctl_t SELinux type can be entered via the ftpdctl_exec_t file type. The default entrypoint paths for the ftpdctl_t domain are the following: /usr/bin/ftpdctl
PROCESS TYPESSELinux 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 ftpdctl policy is very flexible allowing users to setup their ftpdctl processes in as secure a method as possible. The following process types are defined for ftpdctl: ftpdctl_tNote: semanage permissive -a ftpdctl_t can be used to make the process type ftpdctl_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.
BOOLEANSSELinux policy is customizable based on least access required. ftpdctl policy is extremely flexible and has several booleans that allow you to manipulate the policy and run ftpdctl 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
FILE CONTEXTSSELinux 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 ftpdctl policy is very flexible allowing users to setup their ftpdctl processes in as secure a method as possible. STANDARD FILE CONTEXT SELinux defines the file context types for the ftpdctl, if you wanted to store files with these types in a diffent paths, you need to execute the semanage command to sepecify alternate labeling and then use restorecon to put the labels on disk. semanage fcontext -a -t ftpdctl_tmp_t '/srv/myftpdctl_content(/.*)?'
restorecon -R -v /srv/myftpdctl_content Note: SELinux often uses regular expressions to specify labels that match multiple files. The following file types are defined for ftpdctl: ftpdctl_exec_t- Set files with the ftpdctl_exec_t type, if you want to transition an executable to the ftpdctl_t domain. ftpdctl_tmp_t- Set files with the ftpdctl_tmp_t type, if you want to store ftpdctl temporary files in the /tmp directories. Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.
COMMANDSsemanage fcontext can also be used to manipulate default file context mappings. semanage permissive can also be used to manipulate whether or not a process type is permissive. semanage module can also be used to enable/disable/install/remove policy modules. semanage boolean can also be used to manipulate the booleans system-config-selinux is a GUI tool available to customize SELinux policy settings.
