One Identity Safeguard for Privileged Sessions 6.0.10 - Administration Guide

Enabling SSH access to the One Identity Safeguard for Privileged Sessions (SPS) host

Exclusively for troubleshooting purposes, you can access the One Identity Safeguard for Privileged Sessions (SPS) host using SSH.

Completing the Welcome Wizard automatically disables SSH access to SPS. Re-enabling it allows you to connect remotely to the SPS host and login using the root user. The password of the root user is the one you provided in the Welcome Wizard. For details on how to change the root password from the web interface, see Changing the root password of One Identity Safeguard for Privileged Sessions (SPS).

The following encryption algorithms are configured on the local SSH service of SPS:

• Key exchange (KEX) algorithms:

  diffie-hellman-group-exchange-sha256

• Ciphers:

  aes256-ctr,aes128-ctr

• Message authentication codes:

  hmac-sha2-512,hmac-sha2-256

SSH access is, by default, protected against brute-force attacks: after 20 unsuccessful login attempts, the offending IP is blocked from accessing the SSH service for ten minutes.

You can turn off brute force protection by unselecting the Protect against brute-force attacks option for the SSH server.

To enable SSH access to the SPS host

1. Navigate to Basic Settings > Local Services > SSH server.

   Figure 110: Basic Settings > Local Services > SSH server — Enabling remote SSH access to SPS

   

2. Select the Enable option.

   NOTE: Remote SSH access is automatically disabled if Sealed mode is enabled. For details, see Sealed mode.

3. Choose the authentication method for the remote SSH connections.

   • To enable password-based authentication, select the Enable password authentication option.

   • To enable public-key authentication, click in the Authorized keys field, click and upload the public keys of the users who can access and manage SPS remotely via SSH.

     One Identity recommends using 2048-bit RSA keys (or stronger).

4. Choose an address and a port for the SSH server in the Listening addresses section.

   The available addresses correspond to the interface addresses configured in Basic Settings > Network > Interfaces. Only IPv4 addresses can be selected.

   To add multiple addresses, click .

5. (Optional) To permit SSH acces only from selected subnets or IP addresses, select Restrict clients, click and enter the IP address and netmask of the allowed clients.

   Use an IPv4 address.

   To add multiple addresses, click .
