NAMEnx_server_ssh_selinux − Security Enhanced Linux Policy for the nx_server_ssh processes

DESCRIPTIONSecurity-Enhanced Linux secures the nx_server_ssh processes via flexible mandatory access control. The nx_server_ssh processes execute with the nx_server_ssh_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 nx_server_ssh_t

ENTRYPOINTSThe nx_server_ssh_t SELinux type can be entered via the ssh_exec_t file type. The default entrypoint paths for the nx_server_ssh_t domain are the following: /usr/bin/ssh, /usr/libexec/nm-ssh-service

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 ps Policy governs the access confined processes have to files. SELinux nx_server_ssh policy is very flexible allowing users to setup their nx_server_ssh processes in as secure a method as possible. The following process types are defined for nx_server_ssh: nx_server_ssh_tNote: semanage permissive -a nx_server_ssh_t can be used to make the process type nx_server_ssh_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. nx_server_ssh policy is extremely flexible and has several booleans that allow you to manipulate the policy and run nx_server_ssh 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

MANAGED FILESThe SELinux process type nx_server_ssh_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.
ssh_home_t /var/lib/[^/]+/.ssh(/.*)?
/root/.ssh(/.*)?
/var/lib/one/.ssh(/.*)?
/var/lib/pgsql/.ssh(/.*)?
/var/lib/openshift/[^/]+/.ssh(/.*)?
/var/lib/amanda/.ssh(/.*)?
/var/lib/stickshift/[^/]+/.ssh(/.*)?
/var/lib/gitolite/.ssh(/.*)?
/var/lib/nocpulse/.ssh(/.*)?
/var/lib/gitolite3/.ssh(/.*)?
/var/lib/openshift/gear/[^/]+/.ssh(/.*)?
/root/.shosts
/home/[^/]+/.ssh(/.*)?
/home/[^/]+/.ansible/cp/.*
/home/[^/]+/.shosts

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.
