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
12 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
16 For example:
17
18 ps -eZ | grep ptal_t
19
20
21
23 The ptal_t SELinux type can be entered via the ptal_exec_t file type.
24
25 The default entrypoint paths for the ptal_t domain are the following:
26
27 /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
33 You can see the context of a process using the -Z option to ps
34
35 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
39 The following process types are defined for ptal:
40
41 ptal_t
42
43 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
48
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
54
55
56 If you want to allow all domains to execute in fips_mode, you must turn
57 on the fips_mode boolean. Enabled by default.
58
59 setsebool -P fips_mode 1
60
61
62
64 SELinux defines port types to represent TCP and UDP ports.
65
66 You can see the types associated with a port by using the following
67 command:
68
69 semanage port -l
70
71
72 Policy governs the access confined processes have to these ports.
73 SELinux ptal policy is very flexible allowing users to setup their ptal
74 processes in as secure a method as possible.
75
76 The following port types are defined for ptal:
77
78
79 ptal_port_t
80
81
82
83 Default Defined Ports:
84 tcp 5703
85
87 The SELinux process type ptal_t can manage files labeled with the fol‐
88 lowing file types. The paths listed are the default paths for these
89 file types. Note the processes UID still need to have DAC permissions.

133 SELinux requires files to have an extended attribute to define the file
134 type.
135
136 You can see the context of a file using the -Z option to ls
137
138 Policy governs the access confined processes have to these files.
139 SELinux ptal policy is very flexible allowing users to setup their ptal
140 processes in as secure a method as possible.
141
142 STANDARD FILE CONTEXT
143
144 SELinux defines the file context types for the ptal, if you wanted to
145 store files with these types in a diffent paths, you need to execute
146 the semanage command to sepecify alternate labeling and then use
147 restorecon to put the labels on disk.
148
149 semanage fcontext -a -t ptal_var_run_t '/srv/myptal_content(/.*)?'
150 restorecon -R -v /srv/myptal_content
151
152 Note: SELinux often uses regular expressions to specify labels that
153 match multiple files.
154
155 The following file types are defined for ptal:
156
157
158
159 ptal_etc_t
160
161 - Set files with the ptal_etc_t type, if you want to store ptal files
162 in the /etc directories.
163
164
165
166 ptal_exec_t
167
168 - Set files with the ptal_exec_t type, if you want to transition an
169 executable to the ptal_t domain.
170
171
172 Paths:
173 /usr/sbin/ptal-mlcd, /usr/sbin/ptal-photod, /usr/sbin/ptal-printd
174
175
176 ptal_var_run_t
177
178 - Set files with the ptal_var_run_t type, if you want to store the ptal
179 files under the /run or /var/run directory.
180
181
182 Paths:
183 /var/run/ptal-mlcd(/.*)?, /var/run/ptal-printd(/.*)?
184
185
186 Note: File context can be temporarily modified with the chcon command.
187 If you want to permanently change the file context you need to use the
188 semanage fcontext command. This will modify the SELinux labeling data‐
189 base. You will need to use restorecon to apply the labels.
190
191
193 semanage fcontext can also be used to manipulate default file context
194 mappings.
195
196 semanage permissive can also be used to manipulate whether or not a
197 process type is permissive.
198
199 semanage module can also be used to enable/disable/install/remove pol‐
200 icy modules.
201
202 semanage port can also be used to manipulate the port definitions
203
204 semanage boolean can also be used to manipulate the booleans
205
206
207 system-config-selinux is a GUI tool available to customize SELinux pol‐
208 icy settings.
