1.1 Product

Purpose

UTN servers comprise USB Deviceservers and USB Dongleservers. As USB Dongleservers, UTN servers make nonnetwork-ready USB dongles accessible via TCP/IP network. The USB dongles are connected to the USB ports of the UTN server for this purpose. The UTN (UTN = USB to Network) functionality and the corresponding software tool 'SEH UTN Manager' then establish a virtual USB connection between USB dongle and client. The USB dongle can be used as if it were connected locally.

System Requirements

The UTN server has been designed for use in TCP/IP networks. The SEH UTN Manager can be used in the following systems:

• Windows 7 or higher, except Windows Server 2008

(For Windows 7 and Windows Server 2008 R2, KB3033929 http://technet.microsoft.com/en-us/library/security/3033929 must be installed.)

• macOS 10.9 or higher

• Linux: *.deb (for Debian-based systems) and *.rpm (for Red Hat-based systems) installation packages are available for 64-bit systems. A successful installation cannot be guaranteed due to the multitude of Linux varieties! The installation must be carried out on your own. Installation was tested successfully under the following 64-bit systems: Debian: Debian 10, Ubuntu 18.04 Red Hat: Red Hat Enterprise Linux 8, Oracle 8, CentOS 8, SUSE Linux Enterprise 15.1, openSUSE Leap 15.1

•IPv4 TCP/IP network

The SEH Product Manager can be used under the following systems:

• Windows 7 or higher

• macOS 10.12.x or higher

3.1 How to Configure IPv4 Parameters and DNS

In the hardware installation (  ‘Hardware Installation Guide’) the UTN server is connected to the network. The UTN server then checks if it receives an IPv4 network configuration (IP address, subnet mask, gateway, DNS - Domain Name Service) dynamically over DHCP (Dynamic Host Configuration Protocol). If this is not the case, the UTN server assigns itself an IP address via Zeroconf from the address range which is reserved for Zeroconf (169.254.0.0/

16).

Important:

If the UTN server is connected to an IPv6 network, it will automatically receive an additional IPv6 address  25.

The IPv4 address assigned to the UTN server can be found via the SEH UTN Manager and SEH Product Manager software tools. This step usually is carried out during the initial set up (

As an alternative to automatic configuration via DHCP or Zeroconf, you can assign a manual (static) IPv4 network configuration to the UTN server.

We recommend disabling this option once an IP address has been assigned to the UTN server.

ARP/PING Enables/disables the ARP/PING protocol.

You can use the commands ARP and PING to change an IP address. The implementation depends on your system; read the documentation of your operating system.

We recommend disabling this option once an IP address has been assigned to the UTN server.

USB Dongleserver User Manual Windows

Parameters Description

IP Address IP address of the UTN server. Subnet mask Subnet mask of the UTN server.

Subnet masks are used to logically partition big networks into subnetworks. If you are using the UTN server in a subnetwork, it requires the subnet mask of the subnetwork.

Gateway IP address of the network's standard gateway which the UTN server uses.

With a gateway, you can address IP addresses from other networks.

DNS Enables/disables the name resolution via a DNS server.

Important:

Only DNS allows you to use host names instead of IP addresses if you define servers such as e.g. a time server on the UTN server.

Example: Time server configuration ( 36) with instead of

10.168.0.140.

ntp.server.de

Primary DNS server Defines the IP address of the primary DNS server. Secondary DNS server Defines the IP address of the secondary DNS server.

3.2 How to Configure IPv6 Parameters

IPv6 (Internet Protocol Version 6) is the successor of the still predominantly used IPv4 (Internet Protocol Version

128

4). IPv6 offers the same basic functions but has many advantages such as the increased address space of 2

(IPv6) instead of 2

(IPv4) IP addresses and auto configuration.

Important:

IPv6 address notation differs from IPv4: An IPv6 address consists of 128 bits. The normal format of an IPv6 address is eight fields. Each field contains four hexadecimal digits representing 16 bits. Example:

2001:db8:4:0:2c0:ebff:fe0f:3b6b

As a URL in a Web browser, an IPv6 address must be enclosed in square brackets. This prevents port numbers from being mistakenly regarded as part of an IPv6 address. Example:

http://[2001:db8:4:0:2c0:ebff:fe0f:3b6b]:443

The URL will only be accepted by browsers that support IPv6.

You can embed the UTN server into an IPv6 network.

WAR NIN G

UTN functionality ( 2) and the corresponding SEH UTN Manager only work in IPv4 networks. The SEH Product Manager also only works in IPv4 networks.

In pure IPv6 networks, it is only possible to access the dongleserver Control Center ( 10) to administer the UTN server.

The UTN server will automatically receive one or more IPv6 addresses in addition to its IPv4 address. To optimally embed the UTN into your network, you can configure IPv6 parameters.

1. Start the dongleserver Control Center.

2. Select NETWORK – IPv6.

3. Configure the IPv6 parameters; table 3.2-1 25.

4. Click Save & Restart to confirm.  The settings will be saved.

Table 3.2-1: IPv6 parameters

Parameters Description

IPv6 Enables/disables the IPv6 functionality of the UTN server. Automatic configuration Enables/disables the automatic assignment of the IPv6 address to the UTN

server.

IPv6 address Defines an IPv6 unicast address in the format n:n:n:n:n:n:n:n which is manually

assigned to the UTN server.

• Every 'n' represents the hexadecimal value of one of the eight 16 bit elements of the address.

• Leading zeros can be omitted.

• An IPv6 address may be entered or displayed using a shortened version when successive fields contain all zeros (0). In this case, two colons (::) are used.

Router Manually defines a static router to which the UTN server sends its requests.

USB Dongleserver User Manual Windows

Parameters Description

Prefix length Defines the length of the subnet prefix for the IPv6 address. The value 64 is pre-

set. Address ranges (e.g. your network) are specified with prefixes. To do this, the

prefix length (number of bits used) is added to the IPv6 address as a decimal number and the decimal number is preceded by '/'.

3.6 How to Use the UTN Server in VLAN Environments

The UTN server supports VLAN (Virtual Local Area Network) according to 802.1Q. A VLAN divides a physical network into logical subnetworks. Each subnetwork is its own broadcast domain, so

data packets cannot be exchanged between subnetworks. VLANs are used to structure networks and, above all, to secure them.

Each USB device can be assigned to a VLAN. To transfer VLAN data via the USB ports, you must first enter the VLANs on the UTN server. After this, the USB ports used for forwarding data must be linked to the specified VLANs.

The access to USB devices can be regulated particularly well with VLAN: a defined group of network users may use certain USB devices. Inform yourself on how to implement VLAN in your environment and then set up the UTN server for it.

4.2 How to Configure the Device Time

The UTN server has a device time. Correct time information is required for some network mechanisms, such as authentication for example. Device monitoring ( 42) also uses the device time as the timestamp.

The UTN server has a built-in hardware clock. A device time is preconfigured and stored in the hardware clock when the device is produced. The device clock continues to run for a certain period of time, even when the device is switched off. During operation, it is either possible to continue to use the hardware clock, or use a Simple Network Time Protocol (SNTP) server. Such a time server controls the time in a network and synchronizes the time of multiple devices within the network.

We recommend the use of a time server for regular operation, and use of the device clock only for special cases such as the initial installation. This is because a time server guarantees an accurate and synchronous time for all network participants.

In general, today's primary time standard 'UTC' (Universal Time Coordinated) is used. The time zone compensates for location.

Important:

If your network in configured accordingly, the UTN server receives the time server settings automatically via DHCP ( 22). A time server assigned in such a manner always takes precedence over a manually set time server and the device clock.

4.6 How to Monitor the UTN Server

The UTN server has a monitoring function (logging) that collects various values:

• Error (e.g. missing certificates)

• System status (e.g. restarts)

• Parameter Changes

• USB ports and attached devices (e.g. enable or disable a USB port)

• Device access (e.g. logins)

The collected data is stored on the UTN server and can be viewed and deleted directly. You can also export the monitoring logs as a backup

• to your local client

• via WebDAV

•via Email

• via syslog-ng

With syslog-ng-the data is continuously exported. With WebDAV and e-mail you can choose between different time intervals:

• Continuous backup: On the UTN server, the monitoring logs are divided into 2 MB files. Once this size is reached, the file is transferred.

• Daily backup: Transmits the monitoring logs daily at a defined time.

• Manual backup: Transmits the monitoring logs immediately.

This allows you to integrate monitoring of the UTN server appropriately into your network environment and to capture, archive and evaluate the collected data as desired.

5.1 How to Find UTN Servers/USB Devices in the Network

The software tool SEH UTN Manager is used to establish and manage connections to the USB devices connected to the UTN servers.

After the SEH UTN Manager is started, the network has to be scanned for connected UTN servers. The network range to be scanned is freely definable; the search can be effected via multicast and/or in definable IP ranges. The default setting is multicast search in the local network segment.

All UTN servers found and their connected USB devices are displayed in the 'network list'. To use the USB devices connected to the UTN server, you have to add the UTN server to the 'selection list'.

You can also directly add an UTN server to the selection list. To do this, you need to know its IP address.

USB Dongleserver User Manual Windows

5.2 How to Establish a Connection to a USB Device

To connect a USB device to the client, a point-to-point-connection is established between the client and the USB port of the UTN server to which the USB device is connected. The USB device can then be used as if it were directly connected to the client. As long as the connection is established, other users cannot connect the USB device to their client and thus cannot use it. This means that the licensing terms of USB dongles are not changed, circumvented or violated at any time.

Important:

Special case of compound USB devices When connecting certain USB devices to a USB port of the UTN server, the selection list

displays several USB devices on this port. These are compound USB devices. They consist of a hub and one or more USB devices that are all integrated into a single housing.

If the connection is established to a port with a connected compound USB device, all USB devices shown will be connected to the user's client. In this case, each integrated USB device occupies a virtual USB port of the UTN server. If the limit is reached, no further USB devices can be used on this UTN server.

5.3 How to End the Connection between the USB Device and the Client

If a USB device is connected to a client, the connection is of a point-to-point type. As long as the connection is established, other users cannot connect the USB device to their client and thus cannot use it. For this reason, you have to end the connection once you are no longer using the USB device.

To end the connection between USB device and client, deactivate the connection between the client and the USB port of the UTN server to which the USB device is connected.

• Usually the connection is cut by the user via the SEH UTN Manager  54.

• The administrator can also end the connection from the dongleserver Control Center  54.

• You can also set up an automatic deactivation (Auto Disconnect)  56.

• Automatic Deactivation of the Connection after a Time Defined (Auto-Disconnect)  56

• Automatic Connection between a USB Device and Client When a Print Job Is Received (Print-On-Demand) 

57

• Creating a UTN Action: Automated Connections and Program Starts without the SEH UTN Manager Interface

 57

This chapter describes features of the SEH UTN Manager with which automatisms are set up. Users who have expert knowledge in scripting should use the command line tool 'utnm'  63.

Automatic Connection If a USB Device Is Connected (Auto-Connect)

Auto-Connect automatically establishes a connection to a USB port and the connected USB device as soon as a USB device is connected to the USB port. Auto-Connect must be activated for each USB port and works for all USB devices which are connected to the USB port.

 The SEH UTN Manager (complete version) is installed on the client  12.  The USB port is shown in the selection list  50.  You are logged on to the client as administrator.

The dialog Activate Auto-Connect appears.

4. Tick the option for the desired USB ports.

5. Click OK.

 The setting will be saved. The connection to the USB port and the connected USB device is automatically and

immediately activated. If you disconnect the USB device and reconnect it, the connection is again automatically established.

Important:

If you manually deactivate an active USB port connection that was established via Auto-Connect, Auto-Connect will be switched off. If you want to use Auto-Connect again, you will need to reconfigure it later.

Automatic Deactivation of the Connection after a Time Defined (Auto-Disconnect)

Auto-Disconnect deactivates the connection to a USB port and the connected USB device after a previously defined time. 2 minutes before time runs out, the user will receive a notification and is asked to deactivate their connection in order to prevent data loss and error states. Optionally, a one-off prolongation of the connection by the duration of the defined time can be activated. In this case, the user can choose to prolong the connection or decline it when the notification pops up.

Auto-Disconnect allows a large number of network participants to access a small number of devices and avoids idle times.

You can be notified about the free port if a connection is automatically disconnected. For this purpose, set up a notification if the USB port is available  40.

USB Dongleserver User Manual Windows

Creating a UTN Action: Automated Connections and Program Starts without the SEH UTN Manager Interface

UTN Actions are small files which contain a script that automates the connections to USB ports including connected USB devices. The process defined in the script runs automatically when the file is executed. Since the 'SEH UTN Service' is active in the background, the user does not have to start the SEH UTN Manager interface. I.e., UTN Actions can be used with the complete ( 12) and minimal version ( 12).

UTN Actions are for realizing simple scenarios, such as activating a connection, as well as complex procedures, such as activating a connection and starting an application with time delay. You can create the UTN action with a wizard. The wizard is only available in the complete version ( 12) of the SEH UTN Manager. You can create the following UTN Actions:

• UTN Actions which activate and deactivate the device

The wizard will automatically create one UTN Action for the activation and one UTN Action for the deactivation of the USB port, including the connected USB device. Both UTN Actions will be saved to the desktop.

USB Dongleserver User Manual Windows

• UTN Action which starts an application and activates the device

After the selection of the application by the user, the wizard will automatically create a UTN Action to start the application and activate the USB port, including the connected USB device.Additionally, you can define a port deactivation after the application is closed.

• Custom UTN Action (Experts only)

With the help of the wizard, a custom UTN Action can be created. You can create:

- UTN Actions for the activation and deactivation of the USB port and the connected USB device. You can define additional options.

- A script for starting the application and activating the USB port and the connected USB device. Additionally, you can define a delay for the start of the application, the deactivation of the USB port after the closing of the application and additional options. Finally, the complete UTN Action will be created automatically by the SEH UTN Manager and saved by the user.

UTN Actions are based on the command line tool 'utnm'. We recommend experts to use this tool, if they want to create very complex scripts without restraints  63.

 The SEH UTN Manager (complete version) is installed on the client  12.  The USB port is shown in the selection list  50.

1. Start the SEH UTN Manager.

5.7 How to Use the Selection List and Manage User Access Rights with It

The selection list is the main element in the SEH UTN Manager and shows all embedded UTN servers. USB devices can only be used if the UTN server to which they are connected is on the list ( 50). By controlling the selection list you consequently control the user's access to UTN servers and the connected USB devices.

By default, all client users use the global selection list in the SEH UTN Manager. However, you can set a user selection list for the client users. This list can be compiled by the users themselves. Alternatively, you as client administrator restrict user rights and provide a list with which only the UTN servers you define can be used.

Table 5.7-1: Differences in global and user selection list

Global Selection List User Selection List

• All users of a client use the same selection list. • Each user has their own selection list.

All administrators have the same selection list.

• The users can access all devices listed in the selection list. (Provided that no security mechanisms have been specified via the dongleserver Control Center.)

• List is stored at: Registry • List ('ini'-file) is stored at:

%APPDATA%\SEH Computertechnik GmbH\SEH UTN Manager.ini

(%APPDATA% is an environment variable for a Windows user; the path for the current user can be determined with using command line: echo %APPDATA%

Example Windows 10:

echo %APPDATA% yields C:\Users\Username\AppData\Roaming

\SEH Computertechnik GmbH\SEH UTN Manager.ini

Complete path to the ini file:

C:\Users\User name\AppData\Roaming\SEH Computertechnik GmbH\SEH UTN Manager.ini)

• The selection list can be edited by administrators. • The selection list can be edited by administrators or by users with write access to the ini-file. Users with read-only access to the ini-file cannot edit the selection list and have limited access to SEH UTN Managers functions.

USB Dongleserver User Manual Windows

Which functions (selection list editing etc.) can be used in the SEH UTN Manager depends on the selection list type (global/user) and user account type on the client (administrator/user; user with/without write access to ini-file).

5.8 How to Use the SEH UTN Manager without Graphical User Interface

(utnm)

The SEH UTN Manager is available in two versions  12. It can be used without graphical user interface in the minimal version. To do so, the tool 'utnm' is utilized to use UTN features via the command line of the operating system:

• directly, by entering commands in a certain syntax and executing them

• via scripts which contain commands in a certain syntax that will be executed automatically and step by step by the command line interpreter

Use scripts to automate frequently recurring command sequences such as port activations.

The execution of scripts can be automated as well, e.g. by means of login scripts.

6.1 How to Define the Encryption Strength for SSL/TLS Connections

Some connections to and from the UTN server can be encrypted with the protocol SSL (Secure Sockets Layer) and its successor TLS (Transport Layer Security):

• Web access to the dongleserver Control Center: HTTPS ( 74)

• USB connection: Data transfer between the clients and the UTN server and the connected USB devices ( 70)

•Email: POP3 ( 28)

•Email: SMTP ( 28)

The encryption strength and thus the safety of the connection is defined via the encryption protocol and level. You can choose both.

Each encryption level is a collection of what is called cipher suites. A cipher suite in turn is a standardized sequence of four cryptographic algorithms that are used to establish a secure connection. Based on their encryption strength they are grouped to encryption levels. Which cipher suites are supported by the UTN server, i.e. are part of an encryption level, depends on the chosen encryption protocol. You can choose between two encryption levels:

• Any: The encryption is automatically negotiated by both communicating parties. The strongest encryption supported by both parties will always be chosen.

• Low: Only cipher suites with a low encryption are used. (Fast data transfer)

•Medium

• High: Only cipher suites with an strong encryption are used. (Slow data transfer)

When a secure connection is established, the protocol to be used and a list of supported cipher suites are sent to the communication partner. A cipher suite is agreed upon that will be used later on. The strongest cipher suite that is supported by both parties will be used by default.

WAR NIN G

If the communication partner of the UTN server does not support the protocol selected and/or if there is no cipher suite that is supported by both parties, the SSL/ TLS connection will not be established.

If problems occur, select different settings or reset the parameters of the UTN server  95.

If you want the UTN server and its communication partner to automatically negotiate the settings, set both options to Any. With these settings, the chances that a secure connection can be established are the highest.

1. Start the dongleserver Control Center.

2. Select SECURITY – SSL/TLS.

3. In the Encryption protocol area, select the desired protocol.

6.2 How to Encrypt the USB Connection

To secure the USB connections, encrypt the entire data transfer (user data, control data and protocol data) between the clients and the USB devices connected to the UTN server.

The protocols SSL (Secure Sockets Layer) and its successor TLS (Transport Layer Security) are used for encryption. The encryption strength is defined via the encryption protocol and level  70.

WAR NIN G The SEH UTN Manager does not support the encryption level Low. If you set up

Low in combination with an encrypted USB connection, a connection cannot be

established. Use an encryption level as high as possible.

If connections are encrypted, client and UTN server communicate over the encrypted UTN port. By default, that is port 9443. If the port is already in use on your network, e.g. for another application, you can change the port number  38.

6.4 How to Protect Access to the dongleserver Control Center

(User Accounts)

By default, anyone who can find the UTN server on the network can access the dongleserver Control Center. To protect the UTN from unwanted configuration changes, you can set up two user accounts:

• Administrator: Complete access to the dongleserver Control Center. The user can see all pages and change settings.

• Read-only user: Very restricted access to the dongleserver Control Center. The user can only see the 'DASHBOARD' page.

If you have set up user accounts, a login screen is displayed when the dongleserver Control Center is started. You can choose between two login screens:

• Neutral screen: Login screen in which user name and password are to be entered. (better protection)

• List of users: User names are displayed. Only the password has to be entered.

A user account allows for multiple logins, i.e. the account can be used by a single user or by a group of users. Up to 16 users can be logged in at the same time.

Important:

The user accounts for dongleserver Control Center access are also used for SNMP  89. Consider this when setting up user accounts.

For stronger security, you can use a session timeout. If there is no activity within a defined timeout, the user will automatically be logged out.

1. Start the dongleserver Control Center Control Center.

2. Select SECURITY – Control Center.

3. Define the two user accounts. To do this, in the area User accounts enter a User name and Password respectively.

You can show the typing if you want to make sure that there are no typing errors in the password.

4. Tick Restrict Control Center access.

5. Under Login window shows, select the type of login screen: Neutral screen or List of users.

6. Tick the Session timeout option and enter in the box the time in minutes after which the an inactive user should be automatically logged out.

7. To confirm, click Save.

6.5 How to Block UTN Server Ports (TCP Port Access Control)

You can restrict access to the UTN server by blocking ports using 'TCP port access control'. If a port is blocked, the protocols and/or services using this port cannot establish a connection with the UTN server. Thus attackers have less room for attack.

The security level defines which port types are blocked:

• UTN access (blocks UTN ports)

• TCP access (blocks TCP ports: HTTP/HTTPS/UTN)

• All ports (blocks IP ports)

You have to define exceptions so that your desired network elements, e.g. clients or DNS servers, can establish a connection with the UTN server.

WAR NIN G

The ‘ test mode’ is active by default so that you can test your settings without locking yourself out. Your settings will be active until the UTN is restarted, afterwards access is no longer restricted.

After you have successfully tested your settings, you have to deactivate the test mode so that access control is permanent.

1. Start the dongleserver Control Center.

2. Select SECURITY – TCP port access.

3. Tick Port access control.

4. In the Security level area, select the desired protection

5. In the Exceptions area, define the network elements that are to have access to the UTN server. To do this, enter the IP or MAC (hardware) addresses and tick the options.

Important:

• MAC addresses are not delivered through routers!

• The use of wildcards (*) allows you to define subnetworks.

6. Make sure that the Test mode is enabled.

7. Click Save & Restart to confirm. The settings will be saved. The port access control is activated until the device is restarted.

8. Check the port access and if it is possible to reach the dongleserver Control Center.

Important:

If it is not possible to reach the dongleserver Control Center, restart the UTN server  98.

6.6 How to Control Access to USB Devices

You can restrict the access to the USB ports and the connected USB devices:

• USB port key control: Up to two keys are defined for the USB port. Each key can be assigned a validity period (always, expiration date, weekly period). Both the USB port and the connected USB device are shown in the SEH UTN Manager, but no connection can be established. To do so, the key must first be entered in the SEH UTN Manager.

• USB port device assignment: A certain USB device is assigned to a USB port. This is achieved by linking the USB port and USB device through the vendor ID (short VID) and product ID (short PID) of the USB device. The combination of VID and PID is specific to a certain USB device model which means that only USB devices of this specific model can be used on the USB port. This way you can assure, that (security) settings cannot be circumvented by connecting USB devices to other ports.

Power off unused ports to increase security  90.

You can either use one of the two security methods, or both in combination.

6.8 How to Use Certificates

The UTN server has its own certificate management. Digital certificates are data sets, which confirm the identity of a person, object, or organization. In TCP/IP networks they are used to encrypt data and to authenticate communication partners.

The UTN needs a certificate for:

• participating in the authentication mechanisms EAP-TLS, EAP-TTLS and PEAP  86

• protecting email communication (POP3/SMTP via SSL/TLS)  28

• protecting the connection between the clients and the connected USB devices  72

• protecting the connection to the dongleserver Control Center Control Center (with HTTPS)  74

The following certificates can be used in the UTN server:

• 1 self-signed certificate Certificate generated by the UTN server and signed by the UTN server itself. The certificate confirms the UTN server's identity.

• 1 client certificate, i.e. 1 requested certificate or The client certificate confirms the identity of the UTN server with the help of an additional trustworthy authority which is the certification authority (short CA).

- Requested certificate: As first step, a certificate request is generated on the UTN server and then the request

is sent to a certification authority. In the second step, the certification authority creates a certificate based on the request for the UTN server and signs it.

- PKCS#12 certificate Exchange format for certificates. You have a certification authority generate a certificate

which is stored in password-protected PKCS#12 format for the UTN server. Then you transport the PKCS#12 file to the UTN server and install it (and thus the certificate in it).

• 1 S/MIME certificate The UTN server uses the S/MIME Certificate to sign and encrypt emails which is sends. The corresponding private key (PKCS#12 format) has to be installed as certificate of it's own in the email program (Microsoft Outlook etc.) so that emails can be verified and, if necessary, decrypted.

• 1–32 CA certificates, also known as root CA certificates. Certificates which are issued for a certification authority and confirm its identity. They are used for verifying certificates that have been issued by the respective certification authority. In case of the UTN server these are the certificates of communication partners to verify their identity (chain of trust). Thus multi-level public key infrastructures (PKIs) are supported.

1 PKCS#12 certificate

6.9 How to Configure Network Authentication (IEEE 802.1X)

Authentication is the proof and verification of an identity. With it your network is protected from abuse, because only authorized devices have access.

The UTN supports authentication according to the IEEE 802.1X standard which is based on EAP (Extensible Authentication Protocol).

If you use authentication according to IEEE 802.1X in your network, the UTN server can participate:

• Configuring EAP-MD5  86

•Configuring EAP-TLS  86

• Configuring EAP-TTLS  87

• Configuring PEAP  87

•Configuring EAP-FAST  88

Configuring EAP-MD5

EAP-MD5 (Message Digest #5) is a user-based authentication via a RADIUS server. First, you have to create a user (user name and password) on the RADIUS server for the UTN server. Afterwards you set up EAP-MD5 on the UTN server.

 A user account for the UTN server is set up on the RADIUS server.

1. Start the dongleserver Control Center.

2. Select SECURITY – Authentication.

3. From the Authentication method list, select MD5.

4. Enter the user name and the password of the user account that is set up for the UTN server on the RADIUS server.

5. Click Save & Restart to confirm.

 The settings will be saved.

Configuring EAP-TLS

EAP-TLS (Transport Layer Security) is a mutual, certificate based authentication via a RADIUS server. In this method, UTN server and RADIUS server exchange certificates through an encrypted TLS connection.

Both RADIUS and UTN server require a valid, digital certificate signed by a CA. This requires a PKI (Public Key Infrastructure).

WAR NIN G

Follow the instructions below in the given order. If you do not follow the order, the UTN server might not be reachable in the network.

In this case, reset the parameters of the UTN serve  95.

1. Create a certificate request on the UTN server  81.

2. Create a certificate using the certificate request and the authentication server.

3. Install the requested certificate on the UTN server  81.

4. Install the root CA certificate of the certification authority that has issued the certificate of the authentication server (RADIUS) is installed in the UTN server  81.

5. Start the dongleserver Control Center.

6. Select SECURITY – Authentication.

7. Select TLS from the Authentication method list.

8. From the EAP root certificate

 The settings will be saved.

list, select the root CA certificate.

USB Dongleserver User Manual Windows

Configuring EAP-TTLS

In EAP-TTLS (Tunneled Transport Layer Security), a TLS-protected tunnel is used for exchanging secrets. The method consists of two phases:

1. Outer authentication: An encrypted TLS (Transport Layer Security) tunnel is created between UTN server and RADIUS server. To do this, the RADIUS server authenticates itself to the UTN server using a certificate that was signed by a CA.

2. Inner authentication: In the tunnel the authentication (via CHAP, PAP, MS-CHAP, or MS-CHAPv2) takes place.

 A user account for the UTN server is set up on the RADIUS server.  For increased security during connection establishment (optional): The root CA certificate of the certification

authority that has issued the certificate of the authentication server (RADIUS) is installed in the UTN server  81.

1. Start the dongleserver Control Center.

2. Select SECURITY – Authentication.

3. Select TTLS from the Authentication method list.

4. Enter the user name and the password of the user account that is set up for the UTN server on the RADIUS server.

5. Select the settings which secure the communication in the TLS channel.

6. Increase the security during connection establishment (optional): From the list EAP root certificate, select the root CA certificate.

7. Click Save & Restart to confirm.

 The settings will be saved.

Configuring PEAP

With PEAP (Protected Extensible Authentication Protocol), an encrypted TLS (Transport Layer Security) tunnel is established between the UTN server and the RADIUS server. To do this, the RADIUS server authenticates itself to the UTN server using a certificate that was signed by a CA. The TLS channel is then used to establish another connection that can be protected by means of additional EAP authentication methods (e.g. MSCHAPv2).

The method is very similar to EAP-TTLS ( 87), but other methods are used to authenticate the UTN server.

 A user account for the UTN server is set up on the RADIUS server.  For increased security during connection establishment (optional): The root CA certificate of the certification

authority that has issued the certificate of the authentication server (RADIUS) is installed in the UTN server  81.

1. Start the dongleserver Control Center.

2. Select SECURITY – Authentication.

3. Select PEAP from the Authentication method list.

4. Enter the user name and the password of the user account that is set up for the UTN server on the RADIUS server.

5. Select the settings which secure the communication in the TLS channel.

6. Increase the security during connection establishment (optional): From the list EAP root certificate, select the root CA certificate.

7. Click Save & Restart to confirm.

 The settings will be saved.

USB Dongleserver User Manual Windows

Configuring EAP-FAST

EAP-FAST (Flexible Authentication via Secure Tunneling) is a specific EAP method developed by the company Cisco.

As with EAP-TTLS ( 87) and PEAP ( 87) a secure tunnel protects data transmission. However, the server does not authenticate itself with a certificate. Instead it uses PACs (Protected Access Credentials).

 A user account for the UTN server is set up on the RADIUS server.

1. Start the dongleserver Control Center.

2. Select SECURITY – Authentication.

3. Select FAST from the Authentication method list.

4. Enter the user name and the password of the user account that is set up for the UTN server on the RADIUS server.

5. Select the settings intended to secure the communication in the channel.

6. Click Save & Restart to confirm.

 The settings will be saved.

6.10 How to Configure SNMP

SNMP (Simple Network Management Protocol) is protocol for configuring and monitoring network elements. The protocol controls communication between the monitored devices and the monitoring station (SNMP management tool). Information can be read and changed.

SNMP exists in 3 versions, the UTN supports version 1 and 2.

SNMPv1

SNMPv1 is the first and most simple SNMP version. A disadvantage is the insecure access control which is the community: a community groups monitoring station and monitored devices. This makes their administration easier. There are two types of communities, read-only and read/write. For both the community name is also the password used between the monitoring station and the monitored devices. As it is transmitted as clear text, it does not offer sufficient protection.

SNMPv3

SNMPv3 is the newest SNMP version. It contains enhancements and a new security concept which includes, amongst other thins, encryption and authentication. Therefore, a SNMP user with name and password must be created in the monitoring station. This user must then be specified in the UTN server.

Important:

The user accounts are also used to access the dongleserver Control Center and thus are to be defined under SECURITY - Control Center, see ’How to Protect Access to the dongleserver Control Center (User Accounts)’  75.

 SNMPv3 users are created in the monitoring station. (Only for SNMPv3.)  The SNMPv3 users from the monitoring station are specified on the UTN server  75. (Only for SNMPv3.)

1. Start the dongleserver Control Center.

2. Select SECURITY – SNMP.

3. Configure the SNMP parameters; table 6.10-1 89.

4. To confirm, click Save.

 The settings will be saved.

Table 6.10-1:SNMP Parameters

Parameters Description

SNMPv1 Enables/disables SNMPv1. Read-only Enables/disables the write protection for the community. Community SNMP community name Enter the name as it is defined in the monitoring sta-

tion.

Important:

The default name is 'public'. This name is commonly used for read/ write communities. We recommend to change it as soon as possible to increase security.

SNMPv3 Enables/disables SNMPv3. Hash Defines the hash algorithm. Access rights Defines the access rights of the SNMP user. encryption Defines the encryption method.

USB Dongleserver User Manual Windows

7.1 How to Backup Your Configuration

The UTN server includes two backup functions that allow you to access a fixed configuration state at any time.

1. Parameter file:

All parameters are saved in the '<default-name>_parameters.txt' file (exception: passwords). You can view this file on the UTN server and save it to your local client for backup. You can edit the parameter values in the backed up file usin g a text ed itor . Afterward s, the edited file can be lo aded o nto one or more UTN servers. The device(s) will then adopt the parameter values of the file. This allows you to quickly configure a large number of UTN servers. You can find a detailed description of the parameters in the ’Parameter lists’  105.

2. System backup: The entire system (settings, certificates, passwords, etc.) can be saved externally to a Web-

DAV server. With the dongleserver ProMax you can additionally save the system backup to the SD card. By inserting the SD card in another dongleserver ProMAX, you can transfer the system backup to this device. The system backup is automatically updated after a change to the configuration.

WAR NIN G

If the SD card is lost or stolen, your environment becomes vulnerable (certificates, passwords).

Therefore, you have to take all necessary precautions to protect the UTNserver if you use the automatic backup.
