aiccu_selinux(8) SELinux Policy aiccu aiccu_selinux(8)NAMEaiccu_selinux - Security Enhanced Linux Policy for the aiccu processes
Security-Enhanced Linux secures the aiccu processes via flexible manda‐
tory access control.
The aiccu processes execute with the aiccu_t SELinux type. You can
check if you have these processes running by executing the ps command
with the -Z qualifier.
ps -eZ | grep aiccu_t
The aiccu_t SELinux type can be entered via the aiccu_exec_t file type.
The default entrypoint paths for the aiccu_t domain are the following:
SELinux defines process types (domains) for each process running on the

aiccu policy is very flexible allowing users to setup their aiccu pro‐
cesses in as secure a method as possible.
The following process types are defined for aiccu:
Note: semanage permissive -a aiccu_t can be used to make the process
type aiccu_t permissive. SELinux does not deny access to permissive
process types, but the AVC (SELinux denials) messages are still gener‐
SELinux policy is customizable based on least access required. aiccu
policy is extremely flexible and has several booleans that allow you to
manipulate the policy and run aiccu with the tightest access possible.
If you want to allow all daemons to write corefiles to /, you must turn
on the daemons_dump_core boolean. Disabled by default.
setsebool -P daemons_dump_core 1
If you want to enable cluster mode for daemons, you must turn on the
daemons_enable_cluster_mode boolean. Enabled by default.
setsebool -P daemons_enable_cluster_mode 1
If you want to allow all daemons to use tcp wrappers, you must turn on
the daemons_use_tcp_wrapper boolean. Disabled by default.
setsebool -P daemons_use_tcp_wrapper 1
If you want to allow all daemons the ability to read/write terminals,
you must turn on the daemons_use_tty boolean. Disabled by default.
setsebool -P daemons_use_tty 1
If you want to deny any process from ptracing or debugging any other
processes, you must turn on the deny_ptrace boolean. Enabled by
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
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 confined applications to use nscd shared memory,
you must turn on the nscd_use_shm boolean. Disabled by default.
setsebool -P nscd_use_shm 1
The SELinux process type aiccu_t can manage files labeled with the fol‐
lowing file types. The paths listed are the default paths for these
file types. Note the processes UID still need to have DAC permissions.
SELinux requires files to have an extended attribute to define the file
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 aiccu policy is very flexible allowing users to setup their
aiccu processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the aiccu, 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 aiccu_etc_t '/srv/aiccu/content(/.*)?'
restorecon -R -v /srv/myaiccu_content
Note: SELinux often uses regular expressions to specify labels that
match multiple files.
The following file types are defined for aiccu:
- Set files with the aiccu_etc_t type, if you want to store aiccu files
in the /etc directories.
- Set files with the aiccu_exec_t type, if you want to transition an
executable to the aiccu_t domain.
- Set files with the aiccu_initrc_exec_t type, if you want to transi‐
tion an executable to the aiccu_initrc_t domain.
- Set files with the aiccu_var_run_t type, if you want to store the
aiccu files under the /run or /var/run directory.
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 data‐
base. You will need to use restorecon to apply the labels.
semanage fcontext can also be used to manipulate default file context
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 pol‐
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux pol‐
