6 uux_selinux - Security Enhanced Linux Policy for the uux processes
7
9 Security-Enhanced Linux secures the uux processes via flexible manda‐
10 tory access control.
11
12 The uux processes execute with the uux_t SELinux type. You can check if
13 you have these processes running by executing the ps command with the
14 -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep uux_t
19
20
21
23 The uux_t SELinux type can be entered via the uux_exec_t file type.
24
25 The default entrypoint paths for the uux_t domain are the following:
26
27 /usr/bin/uux
28
30 SELinux defines process types (domains) for each process running on the
31 system
32
33 You can see the context of a process using the -Z option to ps
34
35 Policy governs the access confined processes have to files. SELinux
36 uux policy is very flexible allowing users to setup their uux processes
37 in as secure a method as possible.
38
39 The following process types are defined for uux:
40
41 uux_t
42
43 Note: semanage permissive -a uux_t can be used to make the process type
44 uux_t permissive. SELinux does not deny access to permissive process
45 types, but the AVC (SELinux denials) messages are still generated.
46
47
49 SELinux policy is customizable based on least access required. uux
50 policy is extremely flexible and has several booleans that allow you to
51 manipulate the policy and run uux with the tightest access possible.
52
53
54
55 If you want to allow all domains to execute in fips_mode, you must turn
56 on the fips_mode boolean. Enabled by default.
57
58 setsebool -P fips_mode 1
59
60
61
62 If you want to allow system to run with NIS, you must turn on the
63 nis_enabled boolean. Disabled by default.
64
65 setsebool -P nis_enabled 1
66
67
68
70 The SELinux process type uux_t can manage files labeled with the fol‐
71 lowing file types. The paths listed are the default paths for these
72 file types. Note the processes UID still need to have DAC permissions.

95 SELinux requires files to have an extended attribute to define the file
96 type.
97
98 You can see the context of a file using the -Z option to ls
99
100 Policy governs the access confined processes have to these files.
101 SELinux uux policy is very flexible allowing users to setup their uux
102 processes in as secure a method as possible.
103
104 The following file types are defined for uux:
105
106
107
108 uux_exec_t
109
110 - Set files with the uux_exec_t type, if you want to transition an exe‐
111 cutable to the uux_t domain.
112
113
114
115 Note: File context can be temporarily modified with the chcon command.
116 If you want to permanently change the file context you need to use the
117 semanage fcontext command. This will modify the SELinux labeling data‐
118 base. You will need to use restorecon to apply the labels.
119
120
122 semanage fcontext can also be used to manipulate default file context
123 mappings.
124
125 semanage permissive can also be used to manipulate whether or not a
126 process type is permissive.
127
128 semanage module can also be used to enable/disable/install/remove pol‐
129 icy modules.
130
131 semanage boolean can also be used to manipulate the booleans
132
133
134 system-config-selinux is a GUI tool available to customize SELinux pol‐
135 icy settings.
