6 sysstat_selinux - Security Enhanced Linux Policy for the sysstat pro‐
7 cesses
8
10 Security-Enhanced Linux secures the sysstat processes via flexible
11 mandatory access control.
12
13 The sysstat processes execute with the sysstat_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep sysstat_t
20
21
22
24 The sysstat_t SELinux type can be entered via the sysstat_exec_t file
25 type.
26
27 The default entrypoint paths for the sysstat_t domain are the follow‐
28 ing:
29
30 /usr/lib/sa/sa.*, /usr/lib/atsar/atsa.*, /usr/lib/sysstat/sa.*
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 sysstat policy is very flexible allowing users to setup their sysstat
40 processes in as secure a method as possible.
41
42 The following process types are defined for sysstat:
43
44 sysstat_t
45
46 Note: semanage permissive -a sysstat_t can be used to make the process
47 type sysstat_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
51
53 SELinux policy is customizable based on least access required. sysstat
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run sysstat with the tightest access possi‐
56 ble.

59
60 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.

88
89
90
91 If you want to allow all domains write to kmsg_device, while kernel is
92 executed with systemd.log_target=kmsg parameter, you must turn on the
93 domain_can_write_kmsg boolean. Disabled by default.

98
99 If you want to allow all domains to use other domains file descriptors,
100 you must turn on the domain_fd_use boolean. Enabled by default.
101
102 setsebool -P domain_fd_use 1
103
104
105
106 If you want to allow all domains to have the kernel load modules, you
107 must turn on the domain_kernel_load_modules boolean. Disabled by
108 default.
109
110 setsebool -P domain_kernel_load_modules 1
111
112
113
114 If you want to allow all domains to execute in fips_mode, you must turn
115 on the fips_mode boolean. Enabled by default.
116
117 setsebool -P fips_mode 1
118
119
120
121 If you want to enable reading of urandom for all domains, you must turn
122 on the global_ssp boolean. Disabled by default.
123
124 setsebool -P global_ssp 1
125
126
127
128 If you want to allow confined applications to run with kerberos, you
129 must turn on the kerberos_enabled boolean. Enabled by default.
130
131 setsebool -P kerberos_enabled 1
132
133
134
135 If you want to allow system to run with NIS, you must turn on the
136 nis_enabled boolean. Disabled by default.
137
138 setsebool -P nis_enabled 1
139
140
141
142 If you want to allow confined applications to use nscd shared memory,
143 you must turn on the nscd_use_shm boolean. Disabled by default.
144
145 setsebool -P nscd_use_shm 1
146
147
148
150 The SELinux process type sysstat_t can manage files labeled with the
151 following file types. The paths listed are the default paths for these
152 file types. Note the processes UID still need to have DAC permissions.
153
154 sysstat_log_t
155
156 /var/log/sa(/.*)?
157 /opt/sartest(/.*)?
158 /var/log/atsar(/.*)?
159 /var/log/sysstat(/.*)?
160
161
163 SELinux requires files to have an extended attribute to define the file
164 type.
165
166 You can see the context of a file using the -Z option to ls
167
168 Policy governs the access confined processes have to these files.
169 SELinux sysstat policy is very flexible allowing users to setup their
170 sysstat processes in as secure a method as possible.
171
172 STANDARD FILE CONTEXT
173
174 SELinux defines the file context types for the sysstat, if you wanted
175 to store files with these types in a diffent paths, you need to execute
176 the semanage command to sepecify alternate labeling and then use
177 restorecon to put the labels on disk.
178
179 semanage fcontext -a -t sysstat_log_t '/srv/mysysstat_content(/.*)?'
180 restorecon -R -v /srv/mysysstat_content
181
182 Note: SELinux often uses regular expressions to specify labels that
183 match multiple files.
184
185 The following file types are defined for sysstat:
186
187
188
189 sysstat_exec_t
190
191 - Set files with the sysstat_exec_t type, if you want to transition an
192 executable to the sysstat_t domain.
193
194
195 Paths:
196 /usr/lib/sa/sa.*, /usr/lib/atsar/atsa.*, /usr/lib/sysstat/sa.*
197
198
199 sysstat_initrc_exec_t
200
201 - Set files with the sysstat_initrc_exec_t type, if you want to transi‐
202 tion an executable to the sysstat_initrc_t domain.
203
204
205
206 sysstat_log_t
207
208 - Set files with the sysstat_log_t type, if you want to treat the data
209 as sysstat log data, usually stored under the /var/log directory.
210
211
212 Paths:
213 /var/log/sa(/.*)?, /opt/sartest(/.*)?, /var/log/atsar(/.*)?,
214 /var/log/sysstat(/.*)?
215
216
217 Note: File context can be temporarily modified with the chcon command.
218 If you want to permanently change the file context you need to use the
219 semanage fcontext command. This will modify the SELinux labeling data‐
220 base. You will need to use restorecon to apply the labels.
221
222
224 semanage fcontext can also be used to manipulate default file context
225 mappings.
226
227 semanage permissive can also be used to manipulate whether or not a
228 process type is permissive.
229
230 semanage module can also be used to enable/disable/install/remove pol‐
231 icy modules.
232
233 semanage boolean can also be used to manipulate the booleans
234
235
236 system-config-selinux is a GUI tool available to customize SELinux pol‐
237 icy settings.
