squid_cron_selinux — Security Enhanced Linux Policy for the squid_cron processes
Security-Enhanced Linux secures the squid_cron processes via flexible mandatory access control.
The squid_cron processes execute with the squid_cron_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
ps -eZ | grep squid_cron_t
The squid_cron_t SELinux type can be entered via the squid_cron_exec_t file type.
The default entrypoint paths for the squid_cron_t domain are the following:
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 squid_cron policy is very flexible allowing users to setup their squid_cron processes in as secure a method as possible.
The following process types are defined for squid_cron:
Note: semanage permissive -a squid_cron_t can be used to make the process type squid_cron_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.
SELinux policy is customizable based on least access required. squid_cron policy is extremely flexible and has several booleans that allow you to manipulate the policy and run squid_cron with the tightest access possible.
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
The SELinux process type squid_cron_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.
SELinux requires files to have an extended attribute to define the file type.
You can see the context of a file using the -Z option to lsbP
Policy governs the access confined processes have to these files. SELinux squid_cron policy is very flexible allowing users to setup their squid_cron processes in as secure a method as possible.
The following file types are defined for squid_cron:
- Set files with the squid_cron_exec_t type, if you want to transition an executable to the squid_cron_t domain.
Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.
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.
