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 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 For example:
18 ps -eZ | grep sysstat_t
20
24 The sysstat_t SELinux type can be entered via the sysstat_exec_t file
25 type.
26 The default entrypoint paths for the sysstat_t domain are the follow‐
28 ing:
29 /usr/lib(64)?/sa/sa.*, /usr/lib(64)?/atsar/atsa.*, /usr/lib(64)?/sys‐
31 stat/sa.*

34 SELinux defines process types (domains) for each process running on the
35 system
36 You can see the context of a process using the -Z option to ps
38 Policy governs the access confined processes have to files. SELinux
40 sysstat policy is very flexible allowing users to setup their sysstat
41 processes in as secure a method as possible.
42 The following process types are defined for sysstat:
44 sysstat_t
46 Note: semanage permissive -a sysstat_t can be used to make the process
48 type sysstat_t permissive. SELinux does not deny access to permissive
49 process types, but the AVC (SELinux denials) messages are still gener‐
50 ated.
51
54 SELinux policy is customizable based on least access required. sysstat
55 policy is extremely flexible and has several booleans that allow you to
56 manipulate the policy and run sysstat with the tightest access possi‐
57 ble.
58 If you want to allow all daemons the ability to read/write terminals,
62 you must turn on the allow_daemons_use_tty boolean. Disabled by
63 default.
64 setsebool -P allow_daemons_use_tty 1
66 If you want to allow all domains to use other domains file descriptors,
70 you must turn on the allow_domain_fd_use boolean. Enabled by default.
71 setsebool -P allow_domain_fd_use 1
73 If you want to allow sysadm to debug or ptrace all processes, you must
77 turn on the allow_ptrace boolean. Disabled by default.
78 setsebool -P allow_ptrace 1
80 If you want to allow all domains to have the kernel load modules, you
84 must turn on the domain_kernel_load_modules boolean. Disabled by
85 default.
86 setsebool -P domain_kernel_load_modules 1
88 If you want to allow all domains to execute in fips_mode, you must turn
92 on the fips_mode boolean. Enabled by default.
93 setsebool -P fips_mode 1
95 If you want to enable reading of urandom for all domains, you must turn
99 on the global_ssp boolean. Disabled by default.
100 setsebool -P global_ssp 1

106 The SELinux process type sysstat_t can manage files labeled with the
107 following file types. The paths listed are the default paths for these
108 file types. Note the processes UID still need to have DAC permissions.
109 initrc_tmp_t
111 mnt_t
114 /mnt(/[^/]*)
116 /mnt(/[^/]*)?
117 /rhev(/[^/]*)?
118 /media(/[^/]*)
119 /media(/[^/]*)?
120 /etc/rhgb(/.*)?
121 /media/.hal-.*
122 /net
123 /afs
124 /rhev
125 /misc
126 sysstat_log_t
128 /var/log/sa(/.*)?
130 /opt/sartest(/.*)?
131 /var/log/atsar(/.*)?
132 /var/log/sysstat(/.*)?
133 tmp_t
135 /tmp
137 /usr/tmp
138 /var/tmp
139 /tmp-inst
140 /var/tmp-inst
141 /var/tmp/vi.recover

145 SELinux requires files to have an extended attribute to define the file
146 type.
147 You can see the context of a file using the -Z option to ls
149 Policy governs the access confined processes have to these files.
151 SELinux sysstat policy is very flexible allowing users to setup their
152 sysstat processes in as secure a method as possible.
153 STANDARD FILE CONTEXT
155 SELinux defines the file context types for the sysstat, if you wanted
157 to store files with these types in a diffent paths, you need to execute
158 the semanage command to sepecify alternate labeling and then use
159 restorecon to put the labels on disk.
160 semanage fcontext -a -t sysstat_log_t '/srv/mysysstat_content(/.*)?'
162 restorecon -R -v /srv/mysysstat_content
163 Note: SELinux often uses regular expressions to specify labels that
165 match multiple files.
166 The following file types are defined for sysstat:
168 sysstat_exec_t
172 - Set files with the sysstat_exec_t type, if you want to transition an
174 executable to the sysstat_t domain.
175 Paths:
178 /usr/lib(64)?/sa/sa.*, /usr/lib(64)?/atsar/atsa.*,
179 /usr/lib(64)?/sysstat/sa.*
180 sysstat_log_t
183 - Set files with the sysstat_log_t type, if you want to treat the data
185 as sysstat log data, usually stored under the /var/log directory.
186 Paths:
189 /var/log/sa(/.*)?, /opt/sartest(/.*)?, /var/log/atsar(/.*)?,
190 /var/log/sysstat(/.*)?
191 Note: File context can be temporarily modified with the chcon command.
194 If you want to permanently change the file context you need to use the
195 semanage fcontext command. This will modify the SELinux labeling data‐
196 base. You will need to use restorecon to apply the labels.
197
200 semanage fcontext can also be used to manipulate default file context
201 mappings.
202 semanage permissive can also be used to manipulate whether or not a
204 process type is permissive.
205 semanage module can also be used to enable/disable/install/remove pol‐
207 icy modules.
208 semanage boolean can also be used to manipulate the booleans
210 system-config-selinux is a GUI tool available to customize SELinux pol‐
213 icy settings.
