6 comsat_selinux - Security Enhanced Linux Policy for the comsat pro‐
7 cesses
8
10 Security-Enhanced Linux secures the comsat processes via flexible
11 mandatory access control.
12
13 The comsat processes execute with the comsat_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 comsat_t
20
21
22
24 The comsat_t SELinux type can be entered via the comsat_exec_t file
25 type.
26
27 The default entrypoint paths for the comsat_t domain are the following:
28
29 /usr/sbin/in.comsat
30
32 SELinux defines process types (domains) for each process running on the
33 system
34
35 You can see the context of a process using the -Z option to ps
36
37 Policy governs the access confined processes have to files. SELinux
38 comsat policy is very flexible allowing users to setup their comsat
39 processes in as secure a method as possible.
40
41 The following process types are defined for comsat:
42
43 comsat_t
44
45 Note: semanage permissive -a comsat_t can be used to make the process
46 type comsat_t permissive. SELinux does not deny access to permissive
47 process types, but the AVC (SELinux denials) messages are still gener‐
48 ated.
49
50
52 SELinux policy is customizable based on least access required. comsat
53 policy is extremely flexible and has several booleans that allow you to
54 manipulate the policy and run comsat with the tightest access possible.
55
56
57
58 If you want to allow all domains to execute in fips_mode, you must turn
59 on the fips_mode boolean. Enabled by default.
60
61 setsebool -P fips_mode 1
62
63
64
65 If you want to allow system to run with NIS, you must turn on the
66 nis_enabled boolean. Disabled by default.
67
68 setsebool -P nis_enabled 1
69
70
71
73 SELinux defines port types to represent TCP and UDP ports.
74
75 You can see the types associated with a port by using the following
76 command:
77
78 semanage port -l
79
80
81 Policy governs the access confined processes have to these ports.
82 SELinux comsat policy is very flexible allowing users to setup their
83 comsat processes in as secure a method as possible.
84
85 The following port types are defined for comsat:
86
87
88 comsat_port_t
89
90
91
92 Default Defined Ports:
93 udp 512
94
96 The SELinux process type comsat_t can manage files labeled with the
97 following file types. The paths listed are the default paths for these
98 file types. Note the processes UID still need to have DAC permissions.
99
100 comsat_tmp_t
101
102
103 comsat_var_run_t
104
105
106 krb5_host_rcache_t
107
108 /var/tmp/krb5_0.rcache2
109 /var/cache/krb5rcache(/.*)?
110 /var/tmp/nfs_0
111 /var/tmp/DNS_25
112 /var/tmp/host_0
113 /var/tmp/imap_0
114 /var/tmp/HTTP_23
115 /var/tmp/HTTP_48
116 /var/tmp/ldap_55
117 /var/tmp/ldap_487
118 /var/tmp/ldapmap1_0
119
120
122 SELinux requires files to have an extended attribute to define the file
123 type.
124
125 You can see the context of a file using the -Z option to ls
126
127 Policy governs the access confined processes have to these files.
128 SELinux comsat policy is very flexible allowing users to setup their
129 comsat processes in as secure a method as possible.
130
131 STANDARD FILE CONTEXT
132
133 SELinux defines the file context types for the comsat, if you wanted to
134 store files with these types in a different paths, you need to execute
135 the semanage command to specify alternate labeling and then use re‐
136 storecon to put the labels on disk.
137
138 semanage fcontext -a -t comsat_exec_t '/srv/comsat/content(/.*)?'
139 restorecon -R -v /srv/mycomsat_content
140
141 Note: SELinux often uses regular expressions to specify labels that
142 match multiple files.
143
144 The following file types are defined for comsat:
145
146
147
148 comsat_exec_t
149
150 - Set files with the comsat_exec_t type, if you want to transition an
151 executable to the comsat_t domain.
152
153
154
155 comsat_tmp_t
156
157 - Set files with the comsat_tmp_t type, if you want to store comsat
158 temporary files in the /tmp directories.
159
160
161
162 comsat_var_run_t
163
164 - Set files with the comsat_var_run_t type, if you want to store the
165 comsat files under the /run or /var/run directory.
166
167
168
169 Note: File context can be temporarily modified with the chcon command.
170 If you want to permanently change the file context you need to use the
171 semanage fcontext command. This will modify the SELinux labeling data‐
172 base. You will need to use restorecon to apply the labels.
173
174
176 semanage fcontext can also be used to manipulate default file context
177 mappings.
178
179 semanage permissive can also be used to manipulate whether or not a
180 process type is permissive.
181
182 semanage module can also be used to enable/disable/install/remove pol‐
183 icy modules.
184
185 semanage port can also be used to manipulate the port definitions
186
187 semanage boolean can also be used to manipulate the booleans
188
189
190 system-config-selinux is a GUI tool available to customize SELinux pol‐
191 icy settings.
