6 nagios_script_selinux - Security Enhanced Linux Policy for the
7 nagios_script processes
8
10 Security-Enhanced Linux secures the nagios_script processes via flexi‐
11 ble mandatory access control.
12 The nagios_script processes execute with the nagios_script_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep nagios_script_t
20
24 The nagios_script_t SELinux type can be entered via the shell_exec_t,
25 nagios_script_exec_t, nagios_script_exec_t file types.
26 The default entrypoint paths for the nagios_script_t domain are the
28 following:
29 /bin/d?ash, /bin/zsh.*, /bin/ksh.*, /usr/bin/d?ash, /usr/bin/ksh.*,
31 /usr/bin/zsh.*, /bin/esh, /bin/mksh, /bin/sash, /bin/tcsh, /bin/yash,
32 /bin/bash, /bin/fish, /bin/bash2, /usr/bin/esh, /usr/bin/sash,
33 /usr/bin/tcsh, /usr/bin/yash, /usr/bin/mksh, /usr/bin/fish,
34 /usr/bin/bash, /sbin/nologin, /usr/sbin/sesh, /usr/bin/bash2,
35 /usr/sbin/smrsh, /usr/bin/scponly, /usr/sbin/nologin,
36 /usr/libexec/sesh, /usr/sbin/scponlyc, /usr/bin/git-shell,
37 /usr/libexec/sudo/sesh, /usr/bin/cockpit-bridge, /usr/libexec/cockpit-
38 agent, /usr/libexec/git-core/git-shell, /usr/lib/nagios/cgi(/.*)?,

46 SELinux defines process types (domains) for each process running on the
47 system
48 You can see the context of a process using the -Z option to ps
50 Policy governs the access confined processes have to files. SELinux
52 nagios_script policy is very flexible allowing users to setup their
53 nagios_script processes in as secure a method as possible.
54 The following process types are defined for nagios_script:
56 nagios_script_t
58 Note: semanage permissive -a nagios_script_t can be used to make the
60 process type nagios_script_t permissive. SELinux does not deny access
61 to permissive process types, but the AVC (SELinux denials) messages are
62 still generated.
63
66 SELinux policy is customizable based on least access required.
67 nagios_script policy is extremely flexible and has several booleans
68 that allow you to manipulate the policy and run nagios_script with the
69 tightest access possible.
70 If you want to deny any process from ptracing or debugging any other
74 processes, you must turn on the deny_ptrace boolean. Enabled by
75 default.
76 setsebool -P deny_ptrace 1
78 If you want to allow any process to mmap any file on system with
82 attribute file_type, you must turn on the domain_can_mmap_files bool‐
83 ean. Enabled by default.
84 setsebool -P domain_can_mmap_files 1
86 If you want to allow all domains write to kmsg_device, while kernel is
90 executed with systemd.log_target=kmsg parameter, you must turn on the
91 domain_can_write_kmsg boolean. Disabled by default.
92 setsebool -P domain_can_write_kmsg 1
94 If you want to allow all domains to use other domains file descriptors,
98 you must turn on the domain_fd_use boolean. Enabled by default.
99 setsebool -P domain_fd_use 1
101 If you want to allow all domains to have the kernel load modules, you
105 must turn on the domain_kernel_load_modules boolean. Disabled by
106 default.
107 setsebool -P domain_kernel_load_modules 1
109 If you want to allow all domains to execute in fips_mode, you must turn
113 on the fips_mode boolean. Enabled by default.
114 setsebool -P fips_mode 1
116 If you want to enable reading of urandom for all domains, you must turn
120 on the global_ssp boolean. Disabled by default.
121 setsebool -P global_ssp 1
123 If you want to allow httpd cgi support, you must turn on the
127 httpd_enable_cgi boolean. Disabled by default.
128 setsebool -P httpd_enable_cgi 1
130 If you want to allow system to run with NIS, you must turn on the
134 nis_enabled boolean. Disabled by default.
135 setsebool -P nis_enabled 1

141 The SELinux process type nagios_script_t can manage files labeled with
142 the following file types. The paths listed are the default paths for
143 these file types. Note the processes UID still need to have DAC per‐
144 missions.
145 nagios_rw_content_t
147
151 SELinux requires files to have an extended attribute to define the file
152 type.
153 You can see the context of a file using the -Z option to ls
155 Policy governs the access confined processes have to these files.
157 SELinux nagios_script policy is very flexible allowing users to setup
158 their nagios_script processes in as secure a method as possible.
159 The following file types are defined for nagios_script:
161 nagios_script_exec_t
165 - Set files with the nagios_script_exec_t type, if you want to transi‐
167 tion an executable to the nagios_script_t domain.
168 Paths:
171 /usr/lib/nagios/cgi(/.*)?, /usr/lib/icinga/cgi(/.*)?,
172 /usr/lib/cgi-bin/nagios(/.+)?, /usr/lib/nagios/cgi-bin(/.*)?,
173 /usr/lib/cgi-bin/netsaint(/.*)?
174 Note: File context can be temporarily modified with the chcon command.
177 If you want to permanently change the file context you need to use the
178 semanage fcontext command. This will modify the SELinux labeling data‐
179 base. You will need to use restorecon to apply the labels.
180
183 semanage fcontext can also be used to manipulate default file context
184 mappings.
185 semanage permissive can also be used to manipulate whether or not a
187 process type is permissive.
188 semanage module can also be used to enable/disable/install/remove pol‐
190 icy modules.
191 semanage boolean can also be used to manipulate the booleans
193 system-config-selinux is a GUI tool available to customize SELinux pol‐
196 icy settings.
