6 swat_selinux - Security Enhanced Linux Policy for the swat processes
7
9 Security-Enhanced Linux secures the swat processes via flexible manda‐
10 tory access control.
11 The swat processes execute with the swat_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 swat_t
19
23 The swat_t SELinux type can be entered via the swat_exec_t file type.
24 The default entrypoint paths for the swat_t domain are the following:
26 /usr/sbin/swat
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 swat policy is very flexible allowing users to setup their swat pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for swat:
40 swat_t
42 Note: semanage permissive -a swat_t can be used to make the process
44 type swat_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. swat
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run swat with the tightest access possible.
53 If you want to allow users to resolve user passwd entries directly from
57 ldap rather then using a sssd server, you must turn on the authlo‐
58 gin_nsswitch_use_ldap boolean. Disabled by default.
59 setsebool -P authlogin_nsswitch_use_ldap 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 If you want to allow confined applications to run with kerberos, you
72 must turn on the kerberos_enabled boolean. Enabled by default.
73 setsebool -P kerberos_enabled 1
75 If you want to allow system to run with NIS, you must turn on the
79 nis_enabled boolean. Disabled by default.
80 setsebool -P nis_enabled 1
82 If you want to allow confined applications to use nscd shared memory,
86 you must turn on the nscd_use_shm boolean. Disabled by default.
87 setsebool -P nscd_use_shm 1
89
93 SELinux defines port types to represent TCP and UDP ports.
94 You can see the types associated with a port by using the following
96 command:
97 semanage port -l
99 Policy governs the access confined processes have to these ports.
102 SELinux swat policy is very flexible allowing users to setup their swat
103 processes in as secure a method as possible.
104 The following port types are defined for swat:
106 swat_port_t
109 Default Defined Ports:
113 tcp 901
114
116 The SELinux process type swat_t can manage files labeled with the fol‐
117 lowing file types. The paths listed are the default paths for these
118 file types. Note the processes UID still need to have DAC permissions.
119 faillog_t
121 /var/log/btmp.*
123 /var/log/faillog.*
124 /var/log/tallylog.*
125 /var/run/faillock(/.*)?
126 samba_etc_t
128 /etc/samba(/.*)?
130 samba_log_t
132 /var/log/samba(/.*)?
134 samba_secrets_t
136 /etc/samba/smbpasswd
138 /etc/samba/passdb.tdb
139 /etc/samba/MACHINE.SID
140 /etc/samba/secrets.tdb
141 samba_var_t
143 /var/nmbd(/.*)?
145 /var/lib/samba(/.*)?
146 /var/cache/samba(/.*)?
147 swat_tmp_t
149 swat_var_run_t
152
156 SELinux requires files to have an extended attribute to define the file
157 type.
158 You can see the context of a file using the -Z option to ls
160 Policy governs the access confined processes have to these files.
162 SELinux swat policy is very flexible allowing users to setup their swat
163 processes in as secure a method as possible.
164 STANDARD FILE CONTEXT
166 SELinux defines the file context types for the swat, if you wanted to
168 store files with these types in a diffent paths, you need to execute
169 the semanage command to sepecify alternate labeling and then use
170 restorecon to put the labels on disk.
171 semanage fcontext -a -t swat_var_run_t '/srv/myswat_content(/.*)?'
173 restorecon -R -v /srv/myswat_content
174 Note: SELinux often uses regular expressions to specify labels that
176 match multiple files.
177 The following file types are defined for swat:
179 swat_exec_t
183 - Set files with the swat_exec_t type, if you want to transition an
185 executable to the swat_t domain.
186 swat_tmp_t
190 - Set files with the swat_tmp_t type, if you want to store swat tempo‐
192 rary files in the /tmp directories.
193 swat_var_run_t
197 - Set files with the swat_var_run_t type, if you want to store the swat
199 files under the /run or /var/run directory.
200 Note: File context can be temporarily modified with the chcon command.
204 If you want to permanently change the file context you need to use the
205 semanage fcontext command. This will modify the SELinux labeling data‐
206 base. You will need to use restorecon to apply the labels.
207
210 semanage fcontext can also be used to manipulate default file context
211 mappings.
212 semanage permissive can also be used to manipulate whether or not a
214 process type is permissive.
215 semanage module can also be used to enable/disable/install/remove pol‐
217 icy modules.
218 semanage port can also be used to manipulate the port definitions
220 semanage boolean can also be used to manipulate the booleans
222 system-config-selinux is a GUI tool available to customize SELinux pol‐
225 icy settings.
