NAME¶

pegasus_openlmi_logicalfile_selinux - Security Enhanced Linux Policy for the pegasus_openlmi_logicalfile processes

DESCRIPTION¶

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

The pegasus_openlmi_logicalfile processes execute with the pegasus_openlmi_logicalfile_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 pegasus_openlmi_logicalfile_t

ENTRYPOINTS¶

The pegasus_openlmi_logicalfile_t SELinux type can be entered via the user_home_t, pegasus_openlmi_logicalfile_exec_t file types.

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

/home/[^/]+/.+, /usr/libexec/pegasus/cmpiLMI_LogicalFile-cimprovagt

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

The following process types are defined for pegasus_openlmi_logicalfile:

pegasus_openlmi_logicalfile_t

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

BOOLEANS¶

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

If you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on the daemons_dontaudit_scheduling boolean. Enabled by default.

setsebool -P daemons_dontaudit_scheduling 1

If you want to deny user domains applications to map a memory region as both executable and writable, this is dangerous and the executable should be reported in bugzilla, you must turn on the deny_execmem boolean. Disabled by default.

setsebool -P deny_execmem 1

If you want to control the ability to mmap a low area of the address space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on the mmap_low_allowed boolean. Disabled by default.

setsebool -P mmap_low_allowed 1

If you want to disable kernel module loading, you must turn on the secure_mode_insmod boolean. Disabled by default.

setsebool -P secure_mode_insmod 1

If you want to allow unconfined executables to make their heap memory executable. Doing this is a really bad idea. Probably indicates a badly coded executable, but could indicate an attack. This executable should be reported in bugzilla, you must turn on the selinuxuser_execheap boolean. Disabled by default.

setsebool -P selinuxuser_execheap 1

If you want to allow unconfined executables to make their stack executable. This should never, ever be necessary. Probably indicates a badly coded executable, but could indicate an attack. This executable should be reported in bugzilla, you must turn on the selinuxuser_execstack boolean. Enabled by default.

setsebool -P selinuxuser_execstack 1

MANAGED FILES¶

The SELinux process type pegasus_openlmi_logicalfile_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_type

all files on the system

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

The following file types are defined for pegasus_openlmi_logicalfile:

pegasus_openlmi_logicalfile_exec_t

- Set files with the pegasus_openlmi_logicalfile_exec_t type, if you want to transition an executable to the pegasus_openlmi_logicalfile_t domain.

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 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.
