NAME

6       sge_shepherd_selinux - Security Enhanced Linux Policy for the sge_shep‐
7       herd processes
8

DESCRIPTION

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

22

ENTRYPOINTS

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

PROCESS TYPES

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

BOOLEANS

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

MANAGED FILES

105       The SELinux process type sge_shepherd_t can manage files  labeled  with
106       the  following  file types.  The paths listed are the default paths for
107       these file types.  Note the processes UID still need to have  DAC  per‐
108       missions.
109
110       file_type
111
112            all files on the system
113
114

FILE CONTEXTS

116       SELinux requires files to have an extended attribute to define the file
117       type.
118
119       You can see the context of a file using the -Z option to ls
120
121       Policy governs the access  confined  processes  have  to  these  files.
122       SELinux  sge_shepherd  policy  is very flexible allowing users to setup
123       their sge_shepherd processes in as secure a method as possible.
124
125       The following file types are defined for sge_shepherd:
126
127
128
129       sge_shepherd_exec_t
130
131       - Set files with the sge_shepherd_exec_t type, if you want  to  transi‐
132       tion an executable to the sge_shepherd_t domain.
133
134
135
136       Note:  File context can be temporarily modified with the chcon command.
137       If you want to permanently change the file context you need to use  the
138       semanage fcontext command.  This will modify the SELinux labeling data‐
139       base.  You will need to use restorecon to apply the labels.
140
141

COMMANDS

143       semanage fcontext can also be used to manipulate default  file  context
144       mappings.
145
146       semanage  permissive  can  also  be used to manipulate whether or not a
147       process type is permissive.
148
149       semanage module can also be used to enable/disable/install/remove  pol‐
150       icy modules.
151
152       semanage boolean can also be used to manipulate the booleans
153
154
155       system-config-selinux is a GUI tool available to customize SELinux pol‐
156       icy settings.
