sshd_net_selinux(8) SELinux Policy sshd_net sshd_net_selinux(8)NAMEsshd_net_selinux - Security Enhanced Linux Policy for the sshd_net pro‐
cesses
DESCRIPTION
Security-Enhanced Linux secures the sshd_net processes via flexible
mandatory access control.
The sshd_net processes execute with the sshd_net_t SELinux type. You
can check if you have these processes running by executing the ps com‐
mand with the -Z qualifier.
For example:
ps -eZ | grep sshd_net_t
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 ps
Policy governs the access confined processes have to files. SELinux
sshd_net policy is very flexible allowing users to setup their sshd_net
processes in as secure a method as possible.
The following process types are defined for sshd_net:
sshd_net_t
Note: semanage permissive -a sshd_net_t can be used to make the process
type sshd_net_t permissive. SELinux does not deny access to permissive
process types, but the AVC (SELinux denials) messages are still gener‐
ated.
BOOLEANS
SELinux policy is customizable based on least access required.
sshd_net policy is extremely flexible and has several booleans that
allow you to manipulate the policy and run sshd_net 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
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 pol‐
icy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
