webalizer_script_selinux — Security Enhanced Linux Policy for the webalizer_script processes

Description

Security-Enhanced Linux secures the webalizer_script processes via flexible mandatory access control.

The webalizer_script processes execute with the webalizer_script_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.

For example:

ps -eZ | grep webalizer_script_t

Entrypoints

The webalizer_script_t SELinux type can be entered via the shell_exec_t, webalizer_script_exec_t, webalizer_script_exec_t file types.

The default entrypoint paths for the webalizer_script_t domain are the following:

/bin/d?ash, /bin/zsh.*, /bin/ksh.*, /usr/bin/d?ash, /usr/bin/zsh.*, /usr/bin/ksh.*, /bin/esh, /bin/mksh, /bin/sash, /bin/tcsh, /bin/yash, /bin/bash, /bin/fish, /bin/bash2, /usr/bin/esh, /usr/bin/tcsh, /usr/bin/yash, /usr/bin/sash, /usr/bin/mksh, /usr/bin/fish, /usr/bin/bash, /sbin/nologin, /usr/sbin/sesh, /usr/bin/bash2, /usr/sbin/smrsh, /usr/bin/scponly, /usr/sbin/nologin, /usr/libexec/sesh, /usr/sbin/scponlyc, /usr/bin/git-shell, /usr/bin/cockpit-bridge, /usr/libexec/git-core/git-shell

Process Types

SELinux defines process types (domains) for each process running on the system

You can see the context of a process using the -Z option to psbP

Policy governs the access confined processes have to files. SELinux webalizer_script policy is very flexible allowing users to setup their webalizer_script processes in as secure a method as possible.

The following process types are defined for webalizer_script:

webalizer_script_t

Note: semanage permissive -a webalizer_script_t can be used to make the process type webalizer_script_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.

Booleans

SELinux policy is customizable based on least access required. webalizer_script policy is extremely flexible and has several booleans that allow you to manipulate the policy and run webalizer_script with the tightest access possible.

If you want to deny any process from ptracing or debugging any other processes, you must turn on the deny_ptrace boolean. Enabled by default.

setsebool -P deny_ptrace 1

If you want to allow all domains to use other domains file descriptors, you must turn on the domain_fd_use boolean. Enabled by default.

setsebool -P domain_fd_use 1

If you want to allow all domains to have the kernel load modules, you must turn on the domain_kernel_load_modules boolean. Disabled by default.

setsebool -P domain_kernel_load_modules 1

If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.

setsebool -P fips_mode 1

If you want to enable reading of urandom for all domains, you must turn on the global_ssp boolean. Disabled by default.

setsebool -P global_ssp 1

If you want to allow httpd cgi support, you must turn on the httpd_enable_cgi boolean. Disabled by default.

setsebool -P httpd_enable_cgi 1

If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.

setsebool -P nis_enabled 1

Managed Files

The SELinux process type webalizer_script_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.

webalizer_rw_content_t

/var/www/usage(/.*)?

Commands

semanage fcontext can also be used to manipulate default file context mappings.

semanage permissive can also be used to manipulate whether or not a process type is permissive.

semanage module can also be used to enable/disable/install/remove policy modules.

semanage boolean can also be used to manipulate the booleans

system-config-selinux is a GUI tool available to customize SELinux policy settings.
