^{Last Updated:}^2025-04-24

Purpose

The purpose of this article is to provide an overview of the different server settings for the HIAB.

Introduction

The article provides a detailed overview of the HIAB server settings, including the graphical interface for configuration and management. It outlines the requirements for accessing these settings, such as having an HIAB account and a web browser, and describes key functionalities like modifying network settings, managing servers, and configuring protocols like NTP and SMTP. Additionally, it covers remote SSH access, error reporting, and bandwidth limiting, emphasizing the importance of proper configuration for performance and security. The document also highlights access control measures to secure the graphical user interface and the management of SSL certificates for secure communication.

Remote support, attempts to connect directly if proxy doesn't work.

Error Reporting

This feature is used to receive exceptions and errors from HIABs. By receiving and looking into these exceptions/errors, Outpost24 are able to mitigate problems that can affect customers.

To enable filebeat:

Log in to a HIAB scheduler.
Navigate to Main Menu > Settings > Server > Servers tab.
To enable/disable filebeat logs select the checkbox.

To enable metricbeat:

HIAB must have Services enabled and the Error Reporting enabled to send metric-data.

Log in to a HIAB (online HIAB scheduler).
Navigate to Main Menu > Settings > Server > Servers tab.
To enable/disable filebeat logs select the checkbox.

Bandwidth Limiting

The Bandwidth Limiting grid is used to limit the bandwidth used to different networks.

Bandwidth limit settings must be set on the HIAB performing the scanning in a Distributed environment.

Newopens the Maintaining Bandwidth Limit window where the bandwidth limit can be configured with the following options:

Options	Description
Network (CIDR)	Define the network range for the bandwidth limit.
Limit (kbit)	The limit on how much bandwidth the HIAB can use in kbit.

Deleteremoves the selected entry in the Bandwidth Limiting Grid.

Certificate

It is recommended that the customer supply their own certificate and change the default certificate for the HIAB web interface.

In the Certificate tab the SSL certificates can be maintained, allowing secure communication with the HIAB over the HTTPS protocol.
The needed files can be uploaded for setting up the HIAB to authenticate itself correctly, with proper validation.

Supported key formats are RSA^[1] and PKCS #8^[2].

To successfully upload the certificate,

Options	Description
Certificate	Upload the certificate which you have received from your Certificate Authorities (CA). The uploaded .crt or .pem file must start with a ---BEGIN CERTIFICATE--- marker.
Key pair	Upload only the private key associated with the public key present in the certificate. The uploaded key must not be password protected.
CA Certificate (Optional)	Upload the CA Certificate file containing the whole certificate chain to validate the certificate.

In the lower right corner, there are three buttons:

Create CSR – Creates new certificate.
Revert – Reverts to the default certificate.
Save – Saves the new certificate.

By clicking the Create CSR button, the Create CSR window is displayed, allowing you to create a private key file and a Certificate Signing Request (CSR) file using 4096-bit RSA encryption. The following options are configurable when creating the CSR:

Options	Description
Subject Alternative Name	The additional host names (sites, IP addresses, common names, etc.) to be protected by a single SSL Certificate.
Common Name	Define the domain name.
Organization Unit	The division of the organization handling the certificate.
Organization Name	The legal name of the organization.

State	The state/region where the organization is located.
Country	The two-letter ISO code for the country where the organization is located.

Remote

In the Remote tab the remote SSH access to the HIAB console can be maintained.

Settings

In the settings grid, you can choose if whether to allow remote SSH connections to the HIAB console, and if the SSH daemon should be limited only to listen to a specific interface.

Allowed SSH Keys

The remote SSH access to the HIAB console requires valid SSH keys for authentication. The keys listed in the SSH Key Grid are valid for authentication.

If HIAB pingable is set to OFF in the console, remote SSH access to the HIAB console is not possible.

To enable the SSH access, open the HIAB console and press w Configure UI management interface followed by p Toggle pingable for the desired interface.
It is possible to disable or enable columns in the SSH Key Grid.

Options	Description
IP address	Displays if the key is limited to an IP address.
Key Type	The format of the SSH Key (RSA, DSA).
Mode	Displays mode (Console).
Name	Custom name.
SSH Key	SSH Key data.

Newopens the Maintaining Remote SSH Key window where a new key can be created:

Options	Description
From IP address	Limit from what IP address a key can be used for authentication.
Name	Give the Key a custom name.
SSH Key	SSH Key data.

Uploaddisplays a new window where an existing key be uploaded.

Tools

The Tools tab gives you the opportunity to perform network commands while troubleshooting network issues.

Options	Description
Target	The target host that you wish to test with the selected tool.
Ping	Send PING requests to the defined target.
Traceroute	Perform UDP traceroute to the defined target.
TCP traceroute	Perform TCP traceroute to the defined target.
Port	Port number for the TCP traceroute. Not available for Ping and UDP traceroute.

Example:

⚙️

Ping
/usr/bin/ping -c3 <hostname>
/usr/bin/ping6 -c3 <hostname>

Traceroute
/usr/bin/traceroute [-T -p <port>] <hostname>
/usr/bin/traceroute6 [-T -p <port>] <hostname>

The traceroute and ping commands are sent from the appliance they are executed on, in other words, this traffic is not routed through any scanner.

All results from the various troubleshooting tools is displayed in the Results field.

Hosts

The Hosts tab gives you the opportunity to add host names which resolves the defined IP address when performing scans.

Entries are added to the scanner's local hosts file, providing the scanner with the ability to fulfill queries locally before requesting information from a nameserver. There is no limit to the number of entries that can be added.

Newopens the Add Host window where following options can be defined:

Options	Description
IP Address	Define the IP address.
Host Name	Define the host name.

Deleteremoves the selected entry from the list.

Access Control

The Access Control tab is used to limit the IP addresses that can access the Graphical User Interface.
To restrict the use, enter the IP address range which have access to the HIAB Graphical User Interface, make sure that the machine from which the Administrator is entering the IP range is a part of the allowed IP range.
Correct IP ranges is a requirement to prevent any unwarranted denial of access.

Access Control only apply when HIAB is in hardened mode.

Status

The Status tab shows status for the Scheduler and distributed scanners.

Management

The Management tab allows you to remotely access the Graphical User Interface of another HIAB, if the two HIAB can communicate.

New opens the Edit Hiab Management window where the options for the remote HIAB can be configured:

Options	Description
Name	Name of the remote HIAB.
Address	IP address of the remote HIAB.
Port	Port the communication will talk over.
Token	App Token generated within the remote HIAB.

Deleteremoves the selected entry.
