6 squid_script_selinux - Security Enhanced Linux Policy for the
7 squid_script processes
8
10 Security-Enhanced Linux secures the squid_script processes via flexible
11 mandatory access control.
12
13 The squid_script processes execute with the squid_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
17 For example:
18
19 ps -eZ | grep squid_script_t
20
21
22
24 The squid_script_t SELinux type can be entered via the
25 squid_script_exec_t file type.
26
27 The default entrypoint paths for the squid_script_t domain are the fol‐
28 lowing:
29
30 /usr/share/lightsquid/cgi(/.*)?, /usr/lib/squid/cachemgr.cgi
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 squid_script policy is very flexible allowing users to setup their
40 squid_script processes in as secure a method as possible.
41
42 The following process types are defined for squid_script:
43
44 squid_script_t
45
46 Note: semanage permissive -a squid_script_t can be used to make the
47 process type squid_script_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 squid_script policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run squid_script with the tight‐
56 est access possible.
57
58
59
60 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62
63 setsebool -P fips_mode 1
64
65
66
67 If you want to allow httpd cgi support, you must turn on the httpd_en‐
68 able_cgi boolean. Enabled by default.
69
70 setsebool -P httpd_enable_cgi 1
71
72
73
74 If you want to allow system to run with NIS, you must turn on the
75 nis_enabled boolean. Disabled by default.
76
77 setsebool -P nis_enabled 1
78
79
80
81 If you want to allow confined applications to use nscd shared memory,
82 you must turn on the nscd_use_shm boolean. Enabled by default.
83
84 setsebool -P nscd_use_shm 1
85
86
87
89 The SELinux process type squid_script_t can manage files labeled with
90 the following file types. The paths listed are the default paths for
91 these file types. Note the processes UID still need to have DAC per‐
92 missions.
93
94 squid_rw_content_t
95
96
97
99 SELinux requires files to have an extended attribute to define the file
100 type.
101
102 You can see the context of a file using the -Z option to ls
103
104 Policy governs the access confined processes have to these files.
105 SELinux squid_script policy is very flexible allowing users to setup
106 their squid_script processes in as secure a method as possible.
107
108 STANDARD FILE CONTEXT
109
110 SELinux defines the file context types for the squid_script, if you
111 wanted to store files with these types in a different paths, you need
112 to execute the semanage command to specify alternate labeling and then
113 use restorecon to put the labels on disk.
114
115 semanage fcontext -a -t squid_script_exec_t '/srv/squid_script/con‐
116 tent(/.*)?'
117 restorecon -R -v /srv/mysquid_script_content
118
119 Note: SELinux often uses regular expressions to specify labels that
120 match multiple files.
121
122 The following file types are defined for squid_script:
123
124
125
126 squid_script_exec_t
127
128 - Set files with the squid_script_exec_t type, if you want to transi‐
129 tion an executable to the squid_script_t domain.
130
131
132 Paths:
133 /usr/share/lightsquid/cgi(/.*)?, /usr/lib/squid/cachemgr.cgi
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
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.
