NAME

       cronjob_selinux - Security Enhanced Linux Policy for the cronjob processes

DESCRIPTION

       Security-Enhanced Linux secures the cronjob processes via flexible mandatory access control.

       The  cronjob  processes execute with the cronjob_t SELinux type. You can check if you have these processes running by executing the ps com-
       mand with the -Z qualifier.

       For example:

       ps -eZ | grep cronjob_t

ENTRYPOINTS

       The cronjob_t SELinux type can be entered via the user_cron_spool_t, shell_exec_t file types.

       The default entrypoint paths for the cronjob_t domain are the following:

       /var/spool/at(/.*)?,  /var/spool/cron,  /bin/d?ash,  /bin/zsh.*,  /bin/ksh.*,  /usr/bin/d?ash,  /usr/bin/zsh.*,	/usr/bin/ksh.*,  /bin/esh,
       /bin/mksh,  /bin/sash,  /bin/tcsh,  /bin/yash, /bin/bash, /bin/fish, /bin/bash2, /usr/bin/esh, /usr/bin/sash, /usr/bin/tcsh, /usr/bin/yash,
       /usr/bin/fish,  /usr/bin/mksh,	/usr/bin/bash,	 /sbin/nologin,   /usr/sbin/sesh,   /usr/bin/bash2,   /usr/sbin/smrsh,	 /usr/bin/scponly,
       /usr/sbin/nologin, /usr/libexec/sesh, /usr/sbin/scponlyc, /usr/bin/git-shell, /usr/libexec/git-core/git-shell

PROCESS TYPES

       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 cronjob policy is very flexible allowing users to setup their cronjob
       processes in as secure a method as possible.

       The following process types are defined for cronjob:

       cronjob_t

       Note: semanage permissive -a cronjob_t can be used to make the process type cronjob_t permissive. SELinux does not deny access  to  permis-
       sive process types, but the AVC (SELinux denials) messages are still generated.

BOOLEANS

       SELinux	policy	is  customizable based on least access required.  cronjob policy is extremely flexible and has several booleans that allow
       you to manipulate the policy and run cronjob with the tightest access possible.

       If you want to deny any process from ptracing or debugging any other processes, you must  turn  on  the	deny_ptrace  boolean.  Enabled	by
       default.

       setsebool -P deny_ptrace 1

       If you want to allow all domains to use other domains file descriptors, you must turn on the domain_fd_use boolean. Enabled by default.

       setsebool -P domain_fd_use 1

       If  you	want  to  allow  all domains to have the kernel load modules, you must turn on the domain_kernel_load_modules boolean. Disabled by
       default.

       setsebool -P domain_kernel_load_modules 1

       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

       If you want to enable reading of urandom for all domains, you must turn on the global_ssp boolean. Disabled by default.

       setsebool -P global_ssp 1

       If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.

       setsebool -P nis_enabled 1

MANAGED FILES

       The SELinux process type cronjob_t can manage files labeled with the following file types.  The paths listed  are  the  default	paths  for
       these file types.  Note the processes UID still need to have DAC permissions.

       user_home_t

	    /home/[^/]*/.+

       user_tmp_t

	    /var/run/user(/.*)?
	    /tmp/hsperfdata_root
	    /var/tmp/hsperfdata_root
	    /tmp/gconfd-.*

COMMANDS

       semanage 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.
