Port Requirements

To facilitate secure communication and align with our best practice, we strongly encourage the use of Transport Layer Security (TLS) between your security devices and our Adaptive MxDR platform for event forwarding.

While we understand that TLS support may not be available on all devices, if your devices do support TLS communication, we recommend utilizing port 10014 for seamless integration.

In some cases, the upgraded version of the device might incorporate TLS support without prior notice. If you come across such a scenario or for further assistance in configuring TLS, we kindly ask you to reach out to your dedicated Adaptive MxDR Service Delivery Lead.

Device Configuration

Pre-requisite

Generate certificate on CyberHub using the following steps.

1. Go to support user mode by executing following command su - support on Cyberhub terminal and choose option 29 - Manage the TLS certificates.

2. Choose option 2 - View EA Server TLS certificate and this will print Private Key and Certificate content on console.

3. Copy certificate from the console output to a file and save it.

Supported format for the Apache HTTP Server Access Logs:

Combined Log Format:

Defined in apache LogFormat by : %h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-agent}i\"

Configuring Apache HTTP Server Access Logs on Windows and Linux

Windows:

1. By default, Apache is installed in C:\Apache24. If you are using a different directory, adjust the paths accordingly.

2. The main configuration file is typically located at C:\Apache24\conf\httpd.conf. Open httpd.conf in a text editor

3. Find the section in httpd.conf where logging is configured. It It should have below entry:

4. Ensure you have a CustomLog directive pointing to your access log file. Add or modify the line to match the combined log format.

5. Save httpd.conf and close the text editor.

6. Open Command Prompt as an administrator and restart the Apache service

Linux:

1. By default and depending upon Linux distribution, Apache's configuration directory would be /etc/httpd or /etc/apache2. The main configuration file would be located at /etc/httpd/conf/httpd.conf or /etc/apache2/apache2.conf.

2. Based on linux distribution, open httpd.conf or apache2.conf using text editor

or

3. Find the section in httpd.conf/apache2.conf where logging is configured. It should have below entry:

4. Ensure you have a CustomLog directive pointing to your access log file. Add or modify the line to match the combined log format

5. Save the configuration file

6. Restart the Apache service to apply the changes based on linux distribution.
