svirt_socket_selinux: Security Enhanced Linux Policy for the svirt_socket processes
NAMEsvirt_socket_selinux - Security Enhanced Linux Policy for the svirt_socket processes
Security-Enhanced Linux secures the svirt_socket processes via flexible mandatory access control.
The svirt_socket processes execute with the svirt_socket_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
ps -eZ | grep svirt_socket_t
PROCESS TYPESSELinux defines process types (domains) for each process running on the system
You can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux svirt_socket policy is very flexible allowing users to setup their svirt_socket processes in as secure a method as possible.
The following process types are defined for svirt_socket:
Note: semanage permissive -a svirt_socket_t can be used to make the process type svirt_socket_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.
BOOLEANSSELinux policy is customizable based on least access required. svirt_socket policy is extremely flexible and has several booleans that allow you to manipulate the policy and run svirt_socket 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
COMMANDSsemanage 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.
