From f8ca94a5b7c7658631f5b0a9b010251ebbcff65e Mon Sep 17 00:00:00 2001 From: Oliver Walsh Date: Wed, 19 Apr 2017 14:39:42 +0100 Subject: Restrict nova migration ssh tunnel This change enhances the security of the migration ssh tunnel: - The ssh authorized_keys file is only writeable by root. - Creates a new user for migration instead of using root/nova. - Disables SSH forwarding for this user. - Optionally restricts the networks that this user can connect from. - Uses an ssh wrapper command to whitelist the commands that this user can run over ssh. Requires the openstack-nova-migration package from https://review.rdoproject.org/r/6327 bp tripleo-cold-migration Change-Id: Idb56acd1e1ecb5a5fd4d942969be428cc9cbe293 --- .../notes/cold_migration_security-1543136408c76459.yaml | 10 ++++++++++ 1 file changed, 10 insertions(+) create mode 100644 releasenotes/notes/cold_migration_security-1543136408c76459.yaml (limited to 'releasenotes/notes') diff --git a/releasenotes/notes/cold_migration_security-1543136408c76459.yaml b/releasenotes/notes/cold_migration_security-1543136408c76459.yaml new file mode 100644 index 0000000..aaea57e --- /dev/null +++ b/releasenotes/notes/cold_migration_security-1543136408c76459.yaml @@ -0,0 +1,10 @@ +--- +features: + - | + Restrict nova migration ssh tunnel + * The ssh authorized_keys file is only writeable by root. + * Creates a new user for migration instead of using root/nova. + * Disables SSH forwarding for this user. + * Restricts the networks that this user can connect from. + * Uses an ssh wrapper command to whitelist the commands that this user can run over ssh. + Adds new parameter "tripleo::profile::base::nova::migration_ssh_localaddrs" to specify which incoming IPs are allow for SSH tunnel connections. -- cgit 1.2.3-korg
