6 sge_job_ssh_selinux - Security Enhanced Linux Policy for the
7 sge_job_ssh processes
8
10 Security-Enhanced Linux secures the sge_job_ssh processes via flexible
11 mandatory access control.
12 The sge_job_ssh processes execute with the sge_job_ssh_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16 For example:
18 ps -eZ | grep sge_job_ssh_t
20
24 The sge_job_ssh_t SELinux type can be entered via the ssh_exec_t file
25 type.
26 The default entrypoint paths for the sge_job_ssh_t domain are the fol‐
28 lowing:
29 /usr/bin/ssh, /usr/libexec/nm-ssh-service
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 sge_job_ssh policy is very flexible allowing users to setup their
40 sge_job_ssh processes in as secure a method as possible.
41 The following process types are defined for sge_job_ssh:
43 sge_job_ssh_t
45 Note: semanage permissive -a sge_job_ssh_t can be used to make the
47 process type sge_job_ssh_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required.
54 sge_job_ssh policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run sge_job_ssh with the tight‐
56 est access possible.
57 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63 setsebool -P authlogin_nsswitch_use_ldap 1
65 If you want to deny any process from ptracing or debugging any other
69 processes, you must turn on the deny_ptrace boolean. Enabled by
70 default.
71 setsebool -P deny_ptrace 1
73 If you want to allow any process to mmap any file on system with
77 attribute file_type, you must turn on the domain_can_mmap_files bool‐
78 ean. Enabled by default.
79 setsebool -P domain_can_mmap_files 1
81 If you want to allow all domains write to kmsg_device, while kernel is
85 executed with systemd.log_target=kmsg parameter, you must turn on the
86 domain_can_write_kmsg boolean. Disabled by default.
87 setsebool -P domain_can_write_kmsg 1
89 If you want to allow all domains to use other domains file descriptors,
93 you must turn on the domain_fd_use boolean. Enabled by default.
94 setsebool -P domain_fd_use 1
96 If you want to allow all domains to have the kernel load modules, you
100 must turn on the domain_kernel_load_modules boolean. Disabled by
101 default.
102 setsebool -P domain_kernel_load_modules 1
104 If you want to allow all domains to execute in fips_mode, you must turn
108 on the fips_mode boolean. Enabled by default.
109 setsebool -P fips_mode 1
111 If you want to enable reading of urandom for all domains, you must turn
115 on the global_ssp boolean. Disabled by default.
116 setsebool -P global_ssp 1
118 If you want to allow confined applications to run with kerberos, you
122 must turn on the kerberos_enabled boolean. Enabled by default.
123 setsebool -P kerberos_enabled 1
125 If you want to allow system to run with NIS, you must turn on the
129 nis_enabled boolean. Disabled by default.
130 setsebool -P nis_enabled 1
132 If you want to allow confined applications to use nscd shared memory,
136 you must turn on the nscd_use_shm boolean. Disabled by default.
137 setsebool -P nscd_use_shm 1
139 If you want to allow sge to access nfs file systems, you must turn on
143 the sge_use_nfs boolean. Disabled by default.
144 setsebool -P sge_use_nfs 1
146
150 The SELinux process type sge_job_ssh_t can manage files labeled with
151 the following file types. The paths listed are the default paths for
152 these file types. Note the processes UID still need to have DAC per‐
153 missions.

192 semanage fcontext can also be used to manipulate default file context
193 mappings.
194 semanage permissive can also be used to manipulate whether or not a
196 process type is permissive.
197 semanage module can also be used to enable/disable/install/remove pol‐
199 icy modules.
200 semanage boolean can also be used to manipulate the booleans
202 system-config-selinux is a GUI tool available to customize SELinux pol‐
205 icy settings.
