6 ptal_selinux - Security Enhanced Linux Policy for the ptal processes
7
9 Security-Enhanced Linux secures the ptal processes via flexible manda‐
10 tory access control.
11 The ptal processes execute with the ptal_t SELinux type. You can check
13 if you have these processes running by executing the ps command with
14 the -Z qualifier.
15 For example:
17 ps -eZ | grep ptal_t
19
23 The ptal_t SELinux type can be entered via the ptal_exec_t file type.
24 The default entrypoint paths for the ptal_t domain are the following:
26 /usr/sbin/ptal-mlcd, /usr/sbin/ptal-photod, /usr/sbin/ptal-printd
28
30 SELinux defines process types (domains) for each process running on the
31 system
32 You can see the context of a process using the -Z option to ps
34 Policy governs the access confined processes have to files. SELinux
36 ptal policy is very flexible allowing users to setup their ptal pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for ptal:
40 ptal_t
42 Note: semanage permissive -a ptal_t can be used to make the process
44 type ptal_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
50 SELinux policy is customizable based on least access required. ptal
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run ptal with the tightest access possible.
53 If you want to dontaudit all daemons scheduling requests (setsched,
57 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
58 Enabled by default.
59 setsebool -P daemons_dontaudit_scheduling 1
61 If you want to allow all domains to execute in fips_mode, you must turn
65 on the fips_mode boolean. Enabled by default.
66 setsebool -P fips_mode 1
68
72 SELinux defines port types to represent TCP and UDP ports.
73 You can see the types associated with a port by using the following
75 command:
76 semanage port -l
78 Policy governs the access confined processes have to these ports.
81 SELinux ptal policy is very flexible allowing users to setup their ptal
82 processes in as secure a method as possible.
83 The following port types are defined for ptal:
85 ptal_port_t
88 Default Defined Ports:
92 tcp 5703
93
95 The SELinux process type ptal_t can manage files labeled with the fol‐
96 lowing file types. The paths listed are the default paths for these
97 file types. Note the processes UID still need to have DAC permissions.

142 SELinux requires files to have an extended attribute to define the file
143 type.
144 You can see the context of a file using the -Z option to ls
146 Policy governs the access confined processes have to these files.
148 SELinux ptal policy is very flexible allowing users to setup their ptal
149 processes in as secure a method as possible.
150 STANDARD FILE CONTEXT
152 SELinux defines the file context types for the ptal, if you wanted to
154 store files with these types in a different paths, you need to execute
155 the semanage command to specify alternate labeling and then use re‐
156 storecon to put the labels on disk.
157 semanage fcontext -a -t ptal_exec_t '/srv/ptal/content(/.*)?'
159 restorecon -R -v /srv/myptal_content
160 Note: SELinux often uses regular expressions to specify labels that
162 match multiple files.
163 The following file types are defined for ptal:
165 ptal_etc_t
169 - Set files with the ptal_etc_t type, if you want to store ptal files
171 in the /etc directories.
172 ptal_exec_t
176 - Set files with the ptal_exec_t type, if you want to transition an ex‐
178 ecutable to the ptal_t domain.
179 Paths:
182 /usr/sbin/ptal-mlcd, /usr/sbin/ptal-photod, /usr/sbin/ptal-printd
183 ptal_var_run_t
186 - Set files with the ptal_var_run_t type, if you want to store the ptal
188 files under the /run or /var/run directory.
189 Paths:
192 /var/run/ptal-mlcd(/.*)?, /var/run/ptal-printd(/.*)?
193 Note: File context can be temporarily modified with the chcon command.
196 If you want to permanently change the file context you need to use the
197 semanage fcontext command. This will modify the SELinux labeling data‐
198 base. You will need to use restorecon to apply the labels.
199
202 semanage fcontext can also be used to manipulate default file context
203 mappings.
204 semanage permissive can also be used to manipulate whether or not a
206 process type is permissive.
207 semanage module can also be used to enable/disable/install/remove pol‐
209 icy modules.
210 semanage port can also be used to manipulate the port definitions
212 semanage boolean can also be used to manipulate the booleans
214 system-config-selinux is a GUI tool available to customize SELinux pol‐
217 icy settings.
