6 sge_shepherd_selinux - Security Enhanced Linux Policy for the sge_shep‐
7 herd processes
8
10 Security-Enhanced Linux secures the sge_shepherd processes via flexible
11 mandatory access control.
12
13 The sge_shepherd processes execute with the sge_shepherd_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep sge_shepherd_t
20
21
22
24 The sge_shepherd_t SELinux type can be entered via the sge_shep‐
25 herd_exec_t file type.
26
27 The default entrypoint paths for the sge_shepherd_t domain are the fol‐
28 lowing:
29
30 /usr/bin/sge_shepherd
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 sge_shepherd policy is very flexible allowing users to setup their
40 sge_shepherd processes in as secure a method as possible.
41
42 The following process types are defined for sge_shepherd:
43
44 sge_shepherd_t
45
46 Note: semanage permissive -a sge_shepherd_t can be used to make the
47 process type sge_shepherd_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required.
54 sge_shepherd policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run sge_shepherd with the tight‐
56 est access possible.
57
58
59
60 If you want to deny user domains applications to map a memory region as
61 both executable and writable, this is dangerous and the executable
62 should be reported in bugzilla, you must turn on the deny_execmem bool‐
63 ean. Enabled by default.
64
65 setsebool -P deny_execmem 1
66
67
68
69 If you want to allow all domains to execute in fips_mode, you must turn
70 on the fips_mode boolean. Enabled by default.
71
72 setsebool -P fips_mode 1
73
74
75
76 If you want to control the ability to mmap a low area of the address
77 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
78 the mmap_low_allowed boolean. Disabled by default.
79
80 setsebool -P mmap_low_allowed 1
81
82
83
84 If you want to allow confined applications to use nscd shared memory,
85 you must turn on the nscd_use_shm boolean. Disabled by default.
86
87 setsebool -P nscd_use_shm 1
88
89
90
91 If you want to disable kernel module loading, you must turn on the
92 secure_mode_insmod boolean. Enabled by default.
93
94 setsebool -P secure_mode_insmod 1
95
96
97
98 If you want to allow unconfined executables to make their heap memory
99 executable. Doing this is a really bad idea. Probably indicates a
100 badly coded executable, but could indicate an attack. This executable
101 should be reported in bugzilla, you must turn on the selin‐
102 uxuser_execheap boolean. Disabled by default.
103
104 setsebool -P selinuxuser_execheap 1
105
106
107
108 If you want to allow unconfined executables to make their stack exe‐
109 cutable. This should never, ever be necessary. Probably indicates a
110 badly coded executable, but could indicate an attack. This executable
111 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
112 stack boolean. Disabled by default.
113
114 setsebool -P selinuxuser_execstack 1
115
116
117
119 The SELinux process type sge_shepherd_t can manage files labeled with
120 the following file types. The paths listed are the default paths for
121 these file types. Note the processes UID still need to have DAC per‐
122 missions.
123
124 file_type
125
126 all files on the system
127
128
130 SELinux requires files to have an extended attribute to define the file
131 type.
132
133 You can see the context of a file using the -Z option to ls
134
135 Policy governs the access confined processes have to these files.
136 SELinux sge_shepherd policy is very flexible allowing users to setup
137 their sge_shepherd processes in as secure a method as possible.
138
139 The following file types are defined for sge_shepherd:
140
141
142
143 sge_shepherd_exec_t
144
145 - Set files with the sge_shepherd_exec_t type, if you want to transi‐
146 tion an executable to the sge_shepherd_t domain.
147
148
149
150 Note: File context can be temporarily modified with the chcon command.
151 If you want to permanently change the file context you need to use the
152 semanage fcontext command. This will modify the SELinux labeling data‐
153 base. You will need to use restorecon to apply the labels.
154
155
157 semanage fcontext can also be used to manipulate default file context
158 mappings.
159
160 semanage permissive can also be used to manipulate whether or not a
161 process type is permissive.
162
163 semanage module can also be used to enable/disable/install/remove pol‐
164 icy modules.
165
166 semanage boolean can also be used to manipulate the booleans
167
168
169 system-config-selinux is a GUI tool available to customize SELinux pol‐
170 icy settings.
