Performing the initial Network Security configuration for the virtual appliance

The management interface is the port through which the virtual appliance is managed and administered. It is also the port through which integration of the Central Management System appliance and a managed appliance is managed. With the single-port address type, the management interface is also the port through which a managed appliance requests and downloads software updates from the DTI network.

Initial settings need to be configured to set up the management interface, and to allow access to the network, change the default administrator password, and so on.

Trellix recommends that you use the KVM Virtual Machine Manager console. If the license update feature is not enabled, Trellix recommends that you accept the evaluation licenses during the initial configuration, because typing the keys is tedious and prone to error. After the activation code is entered and the admin user has access to the appliance Web UI or CLI , you can copy and paste the license keys.

To perform the initial configuration of a virtual appliance:

Open the KVM Virtual Machine Manager.
Open the virtual appliance you just installed, such as Trellix NX 4500.
At the login prompt, enter admin.
At the password prompt, enter admin.
When prompted to change the password, configure a new password using the username admin password <new password> command. You will be logged out. Log in again with the new password.
Accept the license agreement. The configuration jump-start wizard begins.
Answer the wizard questions as described in Wizard steps.

Wizard Steps

The following table describes the questions the configuration wizard prompts you to answer. As noted in the table, the wizard skips some steps based on your answers to previous steps.

Note

Press Ctrl+C to exit the configuration wizard. After the management interface is configured, an administrator can use the configuration jump-start CLI command to run the wizard again.

Network Security steps

Step	Response
Hostname?	Enter the hostname for the appliance.
Admin password?	(Optional) Enter a new administrator password.
Confirm admin password?	Re-enter the new administrator password.
Enable remote access for 'admin' user?	Enter yes to enable the administrator to log in to the appliance remotely. Enter no to disable remote access.
Enable IPv4 for the management interface (ether1)	Enter yes to enable the IPv4 protocol. If you enter no, IPv4 setup is skipped and you are redirected to the IPv6 configuration, where you can enable or configure IPv6 instead.
Use DHCP on ether1 interface?	Enter no to manually configure your IP address and network settings.
Use zeroconf on ether1 interface?	Enter yes to use zero-configuration (zeroconf) networking. Enter no to specify a static IP address and network mask. (If you specify yes, the next step is skipped.) NOTE: Do not use zeroconf on the primary interface.
Primary IPv4 address and masklen?	Enter the IPv4 address for the management interface in A.B.C.D format and enter the network mask (for example, 1.1.1.2 /24).
Default gateway?	Enter the gateway IP address for the management interface.
Primary DNS server?	Enter the IP address of the DNS server.
Include HOMENET private IP range	Enter yes to configure the following homenet IP range for Snort rules. For further configuration, use the CLI homenet command or Web UI. 10.0.0.0 - 10.255.255.255 (10/8 prefix) 172.16.0.0 - 172.31.255.255 (172.16/12 prefix) 192.168.0.0 - 192.168.255.255 (192.168/16 prefix) HOMENET is a default variable in the Snort rules (snort.conf) supported by the standard libpcap library where you can specify IP addresses that are to be protected. The Network Security appliance allows the configuration of the HOME_NET variable the CLI and WebUI.
Include HOMENET private IPv6 range	Enter yes to configure the following homenet IP range for Snort rules. For further configuration, use the CLI homenet command or Web UI. FC00::/7 HOMENET is a default variable in the Snort rules (snort.conf) supported by the standard libpcap library where you can specify IP addresses that are to be protected. The Network Security appliance allows the configuration of the HOME_NET variable the CLI and WebUI.
Enable IPv6 on management interface (ether1)	Enable IPv6 on management interface (ether1) Note Enable Incident Response or Compromise Assessment features are not supported when IPv6 is selected as yes.
Enable IPv6 autoconfig (SLAAC) on ether1 interface?	Enter yes to enable configuration. Enter no to disable configuration. The default setting is no.
Enable DHCPv6 on ether1 interface?	Enter yes to enable configuration. Enter no to disable configuration. The default setting is no.
Primary IPv6 address and masklen (connection may be lost upon change)?	Enter the IPv6 address in X:X:X:X:X:X:X:X format and the prefix length. Example: 2001:db8::1/64.
IPv6 Default gateway	Enter the gateway IPv6 address for the management interface.
Primary DNS server?	Enter the IPv6 address in X:X:X:X:X:X:X:X format. Example: 2001:db8::1.
IPv6 Primary DNS server	Enter the IPv6 address of the DNS server.
Domain name?	Enter the domain for the management interface (for example, it.acme.com).
Enable Incident Response or Compromise Assessment?	Enter no. These features are not supported in virtual NX deployments.
Enable fenet service?	Enter yes to enable access to the DTI network.
Enable fenet license update service?	Enter yes to enable the licensing service to automatically download your licenses from the DTI network and install them. (If licenses are downloaded and installed successfully, the wizard skips the step that prompts for the product license key and the step that prompts for the security-content updates key.)
Sync appliance time with fenet?	Enter yes to synchronize the appliance time with the DTI server time. If you enabled the licensing service, synchronization prevents a feature from being temporarily unlicensed due to a time gap. The wizard makes three attempts to perform this step before it gives up and moves to the next step.
Update licenses from fenet?	Enter yes to download and install your licenses. The wizard makes three attempts to perform this step before it gives up and moves to the next step.
Enable NTP?	Enter yes to enable automatic time synchronization with one or more Network Time Protocol (NTP) servers. Enter no to manually set the time and date on the appliance. (This step is skipped if you entered yes in the "Sync appliance time with fenet?" step.) If you enter no, specify the time and date in subsequent steps.
Set date(<yyyy>/<mm>/<dd>)?	Enter the appliance date in Greenwich Mean Time (GMT) (UTC+0).
Set time (<hh>:<mm>:<ss>)?	Enter the appliance time in Greenwich Mean Time (GMT) (UTC+0). (This step and the next step are skipped if you entered yes in the "Sync appliance time with fenet?" or "Enable NTP?" step.)
Submission: Configure Interface?	Press Enter to accept ether1 as the interface through which sensors and brokers communicate. Otherwise, enter the name of the other interface. (If you accept ether1, the next three steps are skipped.)
Submission: Interface?	Enter the name of the other interface. Note To keep management and data traffic separate, Trellix recommends that you use another management interface, such as ether2, and not a monitoring interface.
Submission: Use DHCP on <name> interface?	Enter yes to use Dynamic Host Configuration Protocol (DHCP) to configure the submission interface IP address and other network parameters. Enter no to manually configure the IP address and network settings. (If you enter yes, the static IP addressing steps are skipped.)
Submission: IP address and masklen?	Enter the IP address for the submission interface in A.B.C.D format and enter the network mask (for example, 10.1.1.1 /24).
Submission: Default IPv4 gateway?	Enter the gateway IP address for the submission interface.
Product license key?	Enter the product license key you obtained from Trellix, or press Enter to install a 15-day evaluation license. (This step and the next step are skipped if you entered yes in the "Enable fenet license update service?" step and if licenses were successfully installed as a result.)
Security-content updates key?	Enter the security-content license key you obtained from Trellix, or press Enter to skip this step and install the license later.
Send a request to be managed by CMS	Enter yes to add Network Security to Central Management System.
CMS Address	Enter Central Management System IPv4 or IPv6 address.
CMS Server username	Enter the Central Management System server username. (Example: admin)
CMS Server password	Enter the admin password for Central Management System server.
CMS Port?	Enter the port number for the Central Management System appliance
Appliance Reachable to CMS?	Enter yes/no.
Authetication type	Choose the required authentication type. Password authentication SSH-DSA2 and SSH-RSA2 authentication.
