System Settings

Only users who are in the Logpoint Administrator user group can apply or change System Settings.

Logpoint System Settings include:

• Network Time Protocol (NTP) settings, synconizes the time between the network server and the Logpoint server.

• SMTP for email notifications.

• HTTPS — using the default self-signed SSL (Secure Sockets Layer) certificate to securely transfer data.

• Syslog TLS — to use Syslog for log collection. Before setting up TLS, generate a custom certificate and key as listed in HTTPS.

• Apply Data Privacy (optional).

• Activate SOAR Automation, if you have a license.

• Multi port for Collectors to configure and manage multiple listening ports for Syslog and Netflow collectors

• Backup & Restore log and configuration files.

NTP Settings

NTP synchronizes the time of your Logpoint with a network timeserver.

Configuring NTP Settings

1. Go to Settings >> System Settings from the navigation bar and click System Settings.

2. Select NTP.

3. Enable NTP to ensure synced and correct time across Logpoint servers and devices for consistent log analysis.

4. Enter the Server address. You can add multiple server addresses by clicking the plus icon.

1. Click Save Changes.

SMTP

Use Simple Mail Transfer Protocol (SMTP) for email notifications (detections, alerts, incidents). If your mail server supports encryption, StartTLS encrypts the connection and sends emails in encrypted format. You must also configure SMTP before using the Data Privacy Module.

Configuring SMTP

1. Go to Settings >> System Settings from the navigation bar and click System Settings.

2. Select SMTP.

3. In Server/Port, enter the IP address and port number of your mail server.

4. Enter Sender Name and an Email address.

5. By default, Logpoint uses opportunistic TLS, which encrypts emails only if supported by your mail server. Select SSL/TLS to use enforced StartTLS to ensure secure email transmission. Emails are not sent if the connection is not encrypted.

6. If you are using a private mail server, click Browse and upload the certificate signed by a private CA in Certificate. To use a public CA, leave the field blank.

7. If you select Login Required, enter Username and Password.

1. Click Save Changes.

To test SMTP:

1. Click Test SMTP.

2. Enter the Subject of the test e-mail.

3. Enter an Email address.

4. Enter a Message.

1. Click Test SMTP. The email is sent within 20 seconds.

HTTPS

Logpoint provides a default self-signed SSL (Secure Sockets Layer) certificate, which allows secure data transfer to and from Logpoint. You can generate and upload custom SSL certificates for your organization.

Requirements for the custom certificate:

• 2048 bits

• .crt extension

• PEM encoded x.509 standard

The private key file must have a .key extension.

To generate the private key:

Generate private key

openssl genrsa -out private.key 2048

To create the certificate signing request (CSR):

Create CSR

req -new -sha256 -key private.key -out logpointserver.csr

Self-signed or locally generated certificates will trigger browser SSL certificate errors. Use a PKI setup with a trusted Certificate Authority (CA) for certificates that browsers and applications can verify. For more about certificates, see SSL Certificate and common SSL errors: SSL certificate error.

Uploading SSL certificate for HTTPS

1. Go to Settings >> System Settings from the navigation bar and click System Settings.

2. Select HTTPS.

3. Click Browse to find and select the Certificate.

4. Click Browse to find and select the Key.

1. Click Save Changes.

Syslog TLS

Syslog settings allow you to add a custom TLS (Transport Layer Security) certificate to enable secure log collection via Syslog. The syslog collector uses this certificate to maintain the confidentiality and authenticity of the logs transmitted on port 6514. For information on how to generate the custom certificate and key, go to HTTPS.

Upload the Syslog TLS certificate

1. Go to Settings >> System Settings from the navigation bar and click System Settings.

2. Select Syslog.

3. Click Browse to upload the custom TLS Certificate and Key.

4. Enable Add sequence numbers on log received from syslog collector to provide a sequence number to the syslogs. The number is assigned on a device per protocol basis to each log collected from the Syslog Collector.

5. In Message length, enter the size for Syslog messages. Syslog message contains information about the log, such as timestamp, severity, facility, and description. The maximum message size can be 64 KB, with a default size of 12 KB. Any message that exceeds the maximum size is divided into multiple events and shortened at the defined size. For example, if the message length is 40 KB, logs larger than that size are grouped into 40 KB segments.

6. Enable Accept logs from Unregistered Log Sources to accept unregistered logs from any syslog source. The received logs are normalized using _default_syslog normalization policy and stored in the default repo.

1. Click Save Changes.

Support Connection

Support Connection creates an encrypted end-to-end communication channel between Logpoint and Logpoint support. It is used by Logpoint Support to understand, troubleshoot, and fix the issues on your deployment issues. For support connection using the console, run the start-support command. Then, use the ifconfig command to get the IPv4 address from the tap0 interface.

Before enabling support connection, make sure that your firewall is not blocking the connection from your Logpoint to the following:

Domain	Port
reverse.logpoint.com	1193/UDP
customer.logpoint.com	443/TCP

Enabling Support Connection

1. Go to Settings >> System Settings from the navigation bar and click System Settings.

2. Select Support Connection.

3. You must turn on Enable Support Connection for Logpoint to start retrieving the support connection IP. If the Support Connection IP is unavailable, click Refetch.

4. Enter the retrieved support connection IP to the Logpoint Support team.

5. Enter the Support Connection Enable Duration. The support session expires after it exceeds the duration. Support connection never expires if you select 0:0:0 as the time duration, or Enable Support Connection Forever.

1. Click Save Changes.

Multi Port

Multiport for Collectors allows you to configure and manage multiple listening ports for Syslog and Netflow collectors. Custom ports can be added for log collection after creating a device or a log source.

For Logpoint SaaS, only root users can add the custom port(s).

Default Ports

Syslog and Netflow collectors listen on default ports, which are standard network port numbers used to communicate with log sources. With Multiport support, custom ports can be defined within the range 49152–65535 to receive logs.

Once configured, Logpoint listens on all defined ports simultaneously, ensuring flexibility in how logs are ingested.

Collector	Protocol	Default Port	Description
Syslog	TCP/UDP	514	Standard port for unencrypted Syslog communication.
Syslog (SSL)	SSL	515 / 6514	Standard port for secure Syslog over TLS/SSL, ensuring encrypted log transmission. Li-admins can change the default port from 515 to 6514 or vice versa using the change-syslog-ssl-port command.
NetFlow	UDP	9001	Default port for NetFlow communication.

You can define up to ten custom ports per collector. Each port must be unique and cannot be shared with another collector.

Configuring custom port for syslog collector

Syslog Collector enables you to collect data from sources that follow the Syslog protocol, using default ports or custom TCP/UDP or SSL ports to receive logs from devices.

1. Go to Settings >> System Settings from the navigation bar and click System Settings.

2. In Multi Port for Collectors, click Syslog.

3. Enter the Custom Port(s) for the TCP/UDP or SSL Ports.

1. Click Save Changes.

Configuring custom port for Netflow Collector

The Netflow Collector enables you to collect and analyze network traffic statistics from devices including Cisco routers and switches, using the default UDP port or custom UDP ports to receive logs.

1. Go to Settings >> System Settings from the navigation bar and click System Settings.

2. In Multi Port for Collectors, click Netflow.

3. Enter the Custom Port(s) for the UDP Port.
