6 cups_brf_selinux - Security Enhanced Linux Policy for the cups_brf pro‐
7 cesses
8
10 Security-Enhanced Linux secures the cups_brf processes via flexible
11 mandatory access control.
12
13 The cups_brf processes execute with the cups_brf_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep cups_brf_t
20
21
22
24 The cups_brf_t SELinux type can be entered via the cups_brf_exec_t file
25 type.
26
27 The default entrypoint paths for the cups_brf_t domain are the follow‐
28 ing:
29
30 /usr/lib/cups/backend/cups-brf
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 cups_brf policy is very flexible allowing users to setup their cups_brf
40 processes in as secure a method as possible.
41
42 The following process types are defined for cups_brf:
43
44 cups_brf_t
45
46 Note: semanage permissive -a cups_brf_t can be used to make the process
47 type cups_brf_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.
54 cups_brf policy is extremely flexible and has several booleans that al‐
55 low you to manipulate the policy and run cups_brf with the tightest ac‐
56 cess possible.
57
58
59
60 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62
63 setsebool -P fips_mode 1
64
65
66
68 The SELinux process type cups_brf_t can manage files labeled with the
69 following file types. The paths listed are the default paths for these
70 file types. Note the processes UID still need to have DAC permissions.
71
72 admin_home_t
73
74 /root(/.*)?
75
76 print_spool_t
77
78 /var/spool/lpd(/.*)?
79 /var/spool/cups(/.*)?
80 /var/spool/cups-pdf(/.*)?
81
82 user_home_t
83
84 /home/[^/]+/.+
85
86
88 SELinux requires files to have an extended attribute to define the file
89 type.
90
91 You can see the context of a file using the -Z option to ls
92
93 Policy governs the access confined processes have to these files.
94 SELinux cups_brf policy is very flexible allowing users to setup their
95 cups_brf processes in as secure a method as possible.
96
97 STANDARD FILE CONTEXT
98
99 SELinux defines the file context types for the cups_brf, if you wanted
100 to store files with these types in a different paths, you need to exe‐
101 cute the semanage command to specify alternate labeling and then use
102 restorecon to put the labels on disk.
103
104 semanage fcontext -a -t cups_brf_exec_t '/srv/cups_brf/content(/.*)?'
105 restorecon -R -v /srv/mycups_brf_content
106
107 Note: SELinux often uses regular expressions to specify labels that
108 match multiple files.
109
110 The following file types are defined for cups_brf:
111
112
113
114 cups_brf_exec_t
115
116 - Set files with the cups_brf_exec_t type, if you want to transition an
117 executable to the cups_brf_t domain.
118
119
120
121 Note: File context can be temporarily modified with the chcon command.
122 If you want to permanently change the file context you need to use the
123 semanage fcontext command. This will modify the SELinux labeling data‐
124 base. You will need to use restorecon to apply the labels.
125
126
128 semanage fcontext can also be used to manipulate default file context
129 mappings.
130
131 semanage permissive can also be used to manipulate whether or not a
132 process type is permissive.
133
134 semanage module can also be used to enable/disable/install/remove pol‐
135 icy modules.
136
137 semanage boolean can also be used to manipulate the booleans
138
139
140 system-config-selinux is a GUI tool available to customize SELinux pol‐
141 icy settings.
