NAME accountsd_selinux - Security Enhanced Linux Policy for the accountsd processes
DESCRIPTION Security-Enhanced Linux secures the accountsd processes via flexible mandatory access control.
The accountsd processes execute with the accountsd_t SELinux type. You can check if you have these processes running by executing the ps com- mand with the -Z qualifier.
ps -eZ | grep accountsd_t
ENTRYPOINTS The accountsd_t SELinux type can be entered via the accountsd_exec_t file type.
The default entrypoint paths for the accountsd_t domain are the follow- ing:
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 accountsd policy is very flexible allowing users to setup their accountsd processes in as secure a method as possible.
The following process types are defined for accountsd:
Note: semanage permissive -a accountsd_t can be used to make the pro- cess type accountsd_t permissive. SELinux does not deny access to per- missive process types, but the AVC (SELinux denials) messages are still generated.
BOOLEANS SELinux policy is customizable based on least access required. accountsd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run accountsd with the tightest access possible.
If you want to allow all domains to use other domains file descriptors, you must turn on the allow_domain_fd_use boolean. Enabled by default.
setsebool -P allow_domain_fd_use 1
If you want to allow confined applications to run with kerberos, you must turn on the allow_kerberos boolean. Enabled by default.
setsebool -P allow_kerberos 1
If you want to allow sysadm to debug or ptrace all processes, you must turn on the allow_ptrace boolean. Disabled by default.
setsebool -P allow_ptrace 1
If you want to allow system to run with NIS, you must turn on the allow_ypbind boolean. Disabled by default.
setsebool -P allow_ypbind 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 confined applications to use nscd shared memory, you must turn on the nscd_use_shm boolean. Enabled by default.
setsebool -P nscd_use_shm 1
MANAGED FILES The SELinux process type accountsd_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.
FILE CONTEXTS 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 accountsd policy is very flexible allowing users to setup their accountsd processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the accountsd, 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 accountsd_exec_t /srv/accountsd/content(/.*)? restorecon -R -v /srv/myaccountsd_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for accountsd:
- Set files with the accountsd_exec_t type, if you want to transition an executable to the accountsd_t domain.
- Set files with the accountsd_var_lib_t type, if you want to store the accountsd files under the /var/lib 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 database. You will need to use restorecon to apply the labels.
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 pol- icy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux pol- icy settings.
