6 bacula_unconfined_script_selinux - Security Enhanced Linux Policy for
7 the bacula_unconfined_script processes
8
10 Security-Enhanced Linux secures the bacula_unconfined_script processes
11 via flexible mandatory access control.
12
13 The bacula_unconfined_script processes execute with the bacula_uncon‐
14 fined_script_t SELinux type. You can check if you have these processes
15 running by executing the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep bacula_unconfined_script_t
20
21
22
24 The bacula_unconfined_script_t SELinux type can be entered via the bac‐
25 ula_unconfined_script_exec_t file type.
26
27 The default entrypoint paths for the bacula_unconfined_script_t domain
28 are the following:
29
30
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 bacula_unconfined_script policy is very flexible allowing users to set‐
40 up their bacula_unconfined_script processes in as secure a method as
41 possible.
42
43 The following process types are defined for bacula_unconfined_script:
44
45 bacula_unconfined_script_t
46
47 Note: semanage permissive -a bacula_unconfined_script_t can be used to
48 make the process type bacula_unconfined_script_t permissive. SELinux
49 does not deny access to permissive process types, but the AVC (SELinux
50 denials) messages are still generated.
51
52
54 SELinux policy is customizable based on least access required. bac‐
55 ula_unconfined_script policy is extremely flexible and has several
56 booleans that allow you to manipulate the policy and run bacula_uncon‐
57 fined_script with the tightest access possible.
58

60
61 If you want to deny user domains applications to map a memory region as
62 both executable and writable, this is dangerous and the executable
63 should be reported in bugzilla, you must turn on the deny_execmem bool‐
64 ean. Enabled by default.
65
66 setsebool -P deny_execmem 1
67
68
69
70 If you want to control the ability to mmap a low area of the address
71 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
72 the mmap_low_allowed boolean. Disabled by default.
73
74 setsebool -P mmap_low_allowed 1
75
76
77
78 If you want to disable kernel module loading, you must turn on the
79 secure_mode_insmod boolean. Enabled by default.
80
81 setsebool -P secure_mode_insmod 1
82
83
84
85 If you want to allow unconfined executables to make their heap memory
86 executable. Doing this is a really bad idea. Probably indicates a
87 badly coded executable, but could indicate an attack. This executable
88 should be reported in bugzilla, you must turn on the selin‐
89 uxuser_execheap boolean. Disabled by default.
90
91 setsebool -P selinuxuser_execheap 1
92
93
94
95 If you want to allow unconfined executables to make their stack exe‐
96 cutable. This should never, ever be necessary. Probably indicates a
97 badly coded executable, but could indicate an attack. This executable
98 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
99 stack boolean. Disabled by default.
100
101 setsebool -P selinuxuser_execstack 1

106 The SELinux process type bacula_unconfined_script_t can manage files
107 labeled with the following file types. The paths listed are the
108 default paths for these file types. Note the processes UID still need
109 to have DAC permissions.
110
111 file_type
112
113 all files on the system
114
115
117 semanage fcontext can also be used to manipulate default file context
118 mappings.
119
120 semanage permissive can also be used to manipulate whether or not a
121 process type is permissive.
122
123 semanage module can also be used to enable/disable/install/remove pol‐
124 icy modules.
125
126 semanage boolean can also be used to manipulate the booleans
127
128
129 system-config-selinux is a GUI tool available to customize SELinux pol‐
130 icy settings.
