NAME¶

podsleuth_selinux - Security Enhanced Linux Policy for the podsleuth processes

DESCRIPTION¶

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

The podsleuth processes execute with the podsleuth_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 podsleuth_t

ENTRYPOINTS¶

The podsleuth_t SELinux type can be entered via the podsleuth_exec_t file type.

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

/usr/bin/podsleuth, /usr/libexec/hal-podsleuth

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

The following process types are defined for podsleuth:

podsleuth_t

Note: semanage permissive -a podsleuth_t can be used to make the process type podsleuth_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. podsleuth policy is extremely flexible and has several booleans that allow you to manipulate the policy and run podsleuth 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 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 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

MANAGED FILES¶

The SELinux process type podsleuth_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.

initrc_tmp_t

mnt_t

/mnt(/[^/]*)
/mnt(/[^/]*)?
/rhev(/[^/]*)?
/media(/[^/]*)
/media(/[^/]*)?
/etc/rhgb(/.*)?
/media/.hal-.*
/net
/afs
/rhev
/misc

podsleuth_cache_t

/var/cache/podsleuth(/.*)?

podsleuth_tmp_t

podsleuth_tmpfs_t

tmp_t

/tmp
/usr/tmp
/var/tmp
/tmp-inst
/var/tmp-inst
/var/tmp/vi.recover

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

STANDARD FILE CONTEXT

SELinux defines the file context types for the podsleuth, 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 podsleuth_tmpfs_t '/srv/mypodsleuth_content(/.*)?'
restorecon -R -v /srv/mypodsleuth_content

Note: SELinux often uses regular expressions to specify labels that match multiple files.

The following file types are defined for podsleuth:

podsleuth_cache_t

- Set files with the podsleuth_cache_t type, if you want to store the files under the /var/cache directory.

podsleuth_exec_t

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

Paths:

/usr/bin/podsleuth, /usr/libexec/hal-podsleuth

podsleuth_tmp_t

- Set files with the podsleuth_tmp_t type, if you want to store podsleuth temporary files in the /tmp directories.

podsleuth_tmpfs_t

- Set files with the podsleuth_tmpfs_t type, if you want to store podsleuth files on a tmpfs file system.

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.
