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 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 For example:
18 ps -eZ | grep squid_script_t
20
24 The squid_script_t SELinux type can be entered via the
25 squid_script_exec_t, squid_script_exec_t file types.
26 The default entrypoint paths for the squid_script_t domain are the fol‐
28 lowing:
29 /usr/share/lightsquid/cgi(/.*)?, /usr/lib/squid/cachemgr.cgi,
31 /usr/share/lightsquid/cgi(/.*)?, /usr/lib/squid/cachemgr.cgi
32
34 SELinux defines process types (domains) for each process running on the
35 system
36 You can see the context of a process using the -Z option to ps
38 Policy governs the access confined processes have to files. SELinux
40 squid_script policy is very flexible allowing users to setup their
41 squid_script processes in as secure a method as possible.
42 The following process types are defined for squid_script:
44 squid_script_t
46 Note: semanage permissive -a squid_script_t can be used to make the
48 process type squid_script_t permissive. SELinux does not deny access to
49 permissive process types, but the AVC (SELinux denials) messages are
50 still generated.
51
54 SELinux policy is customizable based on least access required.
55 squid_script policy is extremely flexible and has several booleans that
56 allow you to manipulate the policy and run squid_script with the tight‐
57 est access possible.
58 If you want to allow all domains to execute in fips_mode, you must turn
62 on the fips_mode boolean. Enabled by default.
63 setsebool -P fips_mode 1
65 If you want to allow httpd cgi support, you must turn on the
69 httpd_enable_cgi boolean. Enabled by default.
70 setsebool -P httpd_enable_cgi 1
72 If you want to allow confined applications to use nscd shared memory,
76 you must turn on the nscd_use_shm boolean. Disabled by default.
77 setsebool -P nscd_use_shm 1
79
83 The SELinux process type squid_script_t can manage files labeled with
84 the following file types. The paths listed are the default paths for
85 these file types. Note the processes UID still need to have DAC per‐
86 missions.
87 squid_rw_content_t
89
93 SELinux requires files to have an extended attribute to define the file
94 type.
95 You can see the context of a file using the -Z option to ls
97 Policy governs the access confined processes have to these files.
99 SELinux squid_script policy is very flexible allowing users to setup
100 their squid_script processes in as secure a method as possible.
101 The following file types are defined for squid_script:
103 squid_script_exec_t
107 - Set files with the squid_script_exec_t type, if you want to transi‐
109 tion an executable to the squid_script_t domain.
110 Paths:
113 /usr/share/lightsquid/cgi(/.*)?, /usr/lib/squid/cachemgr.cgi
114 Note: File context can be temporarily modified with the chcon command.
117 If you want to permanently change the file context you need to use the
118 semanage fcontext command. This will modify the SELinux labeling data‐
119 base. You will need to use restorecon to apply the labels.
120
123 semanage fcontext can also be used to manipulate default file context
124 mappings.
125 semanage permissive can also be used to manipulate whether or not a
127 process type is permissive.
128 semanage module can also be used to enable/disable/install/remove pol‐
130 icy modules.
131 semanage boolean can also be used to manipulate the booleans
133 system-config-selinux is a GUI tool available to customize SELinux pol‐
136 icy settings.
