SSH

This chapter contains an example of a basic Fudo PAM configuration, to monitor SSH access to a remote server. In this scenario, the user connects to the remote server over the SSH protocol and logs in to the Fudo PAM using an individual login and password combination (john_smith/john). When establishing the connection with the remote server, Fudo PAM substitutes the login and the password with the previously defined values: root/password (authentication modes are described in the User authentication modes section).

Prerequisites

Description below assumes that the system has been already initiated. The initiation procedure is described in the System initiation topic.

Configuration

Adding a server

Server is a definition of the IT infrastructure resource, which can be accessed over one of the specified protocols.

1. Select Management > Servers.
2. Click Add and select Static server.

3. Provide essential configuration parameters:

Parameter	Value
General
Name	ssh_server
Description
Blocked
Protocol	SSH
Legacy ciphers
Bind address	Any
Permissions
Granted users
Server addresses
IP address	10.0.150.150
Port	22

4. Click i to download the target server’s public key.

5. Click Save.

Adding a user

User defines a subject entitled to connect to servers within monitored IT infrastructure. Detailed object definition (i.e. unique login and domain combination, full name, email address etc.) enables precise accountability of user actions when login and password are substituted with a shared account login credentials.

1. Select Management > Users.
2. Click Add.
3. Provide essential user information:

Parameter	Value
General
Login	john_smith
Fudo domain
Blocked
Account validity	Indefinite
Role	user
Preferred language	English
Safes
Full name	John Smith
Email	john@smith.com
Organization
Phone
AD Domain
LDAP Base
Permissions
Granted users
Authentication
Authentication failures
Enforce static password complexity
Type	Password
Password	john
Repeat password	john

4. Click Save.

Adding a listener

Listener determines server connection mode (proxy, gateway, transparent, bastion) as well as its specifics.

1. Select Management > Listeners.
2. Click Add.

3. Provide essential configuration parameters:

Parameter	Value
General
Name	ssh_listener
Blocked
Protocol	SSH
Legacy ciphers
Case insensitivity
Permissions
Granted users
Connection
Mode	proxy
Local address	10.0.150.151
Port	1022
External address
External port

4. Click i to generate the proxy server’s private key or i to upload the .PEM file private key definition.

Note

For security reasons the form displays server’s public key derived from the generated or uploaded private key.

5. Click Save.

Adding an account

Account defines the privileged account existing on the monitored server. It specifies the actual login credentials, user authentication mode: anonymous (without user authentication), regular (with login credentials substitution) or forward (with login and password forwarding); password changing policy as well as the password changer itself.

1. Select Management > Accounts.
2. Click Add.

3. Provide essential configuration parameters:

Parameter	Value
General
Name	admin_ssh_server
Blocked
Type	regular
Session recording	all
Notes
Data retention
Override global retention settings
Delete session data after	61 days
Permissions
Granted users
Server
Server	ssh_server
Credentials
Domain
Login	root
Replace secret with	with password
Password	password
Repeat password	password
Password change policy	Static, without restrictions

4. Click i to generate the proxy server’s private key or i to upload the .PEM file private key definition.

Note

For security reasons the form displays server’s public key derived from the generated or uploaded private key.

5. Click Save.

Defining a safe

Safe directly regulates user access to monitored servers. It specifies available protocols’ features, policies and other details concerning users and servers relations.

1. Select Management > Safes.
2. Click Add.

3. Provide essential configuration parameters:

Parameter	Value
General
Name	ssh_safe
Notifications
Login reason
Require approval
Policies
Note access	No access
Protocol functionality
RDP
SSH
VNC

4. Select Users tab.
5. Click Add user.
6. Find John and click ..
7. Click OK.
8. Select Accounts tab.
9. Click Add account.
10. Find the admin_ssh_server object and click ..
11. Click OK.
12. Click in the Listeners column.
13. Find the ssh_listener object and click ..
14. Click OK.
15. Click Save.

Establishing connection

At this point john_smith can connect to the target host over the SSH protocol.

Example:

Note

Note that the fingerprint displayed when connecting to the target host for the first time is the same as was generated during server configuration.

After accepting the connection, user will be asked for the password. After successful authentication Fudo PAM starts recording user’s activities.

Viewing user session

1. Open a web browser and go to the 10.0.150.151 web address.
2. Enter the login and password to login to the Fudo PAM administration panel.

3. Select Management > Sessions.
4. Find John Smith’s session and click i.
