CyberHub Deployment Guide for AWS Environment - EU Region
- Aparna Rr
This deployment guide will help Accenture Adaptive MxDR customers to build CyberHub for AWS using CloudFormation.
The document includes the following topics:
Introduction to the Accenture CyberHub
The Accenture CyberHub is designed to collect, compress, and transmit your devices log data securely to the Google Log forwarder for analysis and storage.
Getting Started
The CyberHub is mainly focused on supporting wide range of secure services for customer devices. Devices logs can be processed and analyzed in CyberHub and gathered data can securely transported.
Data collection
Security event sources detect and log network and endpoints activity.
Log data is gathered by Event Collectors and sent to an Event Translator Service. Event Collectors gathers, filter, and aggregate the log data and send both raw and processed log data to the Event Translator Service for transmission to the CyberHub.
A data forwarding service or Google Log Forwarder sends raw / processed security data directly to Chronicle SIEM. The security data is encrypted while in transit to Chronicle.
CyberHub Onboarding Process
Onboarding is the act of configuring, establishing, and validating the flow of data from your devices into the Adaptive MxDR. All devices must be onboarded prior to the Adaptive MxDR being able to utilize data from the device. The CyberHub onboarding process is as follows:
The image of an AWS CyberHub is in the form of Amazon Machine Image (AMI) which will be transferred to customer AWS storage Account.
Connectivity needs to be established for the CyberHub to access all required services.
CyberHub virtual hardware requirements need to be in place, as specified in the prerequisites section.
CyberHub needs to be deployed by following the deployment instructions.
Your Accenture SDL need to be informed about every new deployed CyberHub .
CyberHub connectivity details such as Internal IP, hostname and DNS details need to be shared via CyberHub Tech Stack created on the Adaptive MxDR Portal.
Accenture Team will be performing CyberHub connectivity tests and review deployment success.
After the CyberHub is fully deployed, Accenture Team will perform CyberHub baseline and apply hardening scripts. From this point only certified Accenture Adaptive MxDR Technical resources will be able to access and solely manage the CyberHub.
Access to the CyberHub can’t be granted to anyone else.
The following information is required for each CyberHub:
Table - 1.1: Installation Requirements
Host Name | The host name of the computer where the CyberHub will reside; i.e., CyberHub001. |
Domain name server | A comma-separated list of local domain name server IP addresses. This allows the collector to resolve logged host names to IP addresses, which is critical for Accenture MDR analysis. |
Subnet mask | The subnet mask for the network where the CyberHub will reside, in IPv4 format; i.e., 255.255.255.0 |
Gateway | The IP address for the default gateway the CyberHub will use, in IPv4 format; i.e., 128.0.0.1 |
IP address | Static/reserved IP address for the CyberHub , in IPv4 format; i.e., 128.0.0.8 |
Domain | The CyberHub 's domain name; can be any name you prefer and does not have to be the actual local domain name; i.e., example.customer.com |
Prerequisites
To request the CyberHub Amazon Machine Image.
Kindly reach out to SOC onboarding team along with AWS account ID with region via service request.
Onboarding engineer will update the respective service request, once the CyberHub AMI is shared over the mentioned AWS account ID to proceed with the below steps.
Security group rules (Inbound and Outbound), Instance Type, 250 GB HDD and Elastic IP are assigned automatically to the instance during the stack creation process.
The above CyberHub Specifications for estimation and guidance only. Post deployment, a detailed understanding on amount of log data being generated in the environment, in combination with the log processing capacity will be required to.
Before installing the CyberHub, please make sure the following prerequisites are met.
CyberHub can connect from SOC using the AWS Session Manager. Please discuss this subject with your Technical Project Manager for more queries.
Virtual hardware is provisioned, as per specification listed below and can support the CyberHub OS base. CyberHub image is currently based on Ubuntu 20.4 version.
CyberHub requires to have access to the DNS server holding DNS A-records of all event sources planned to be integrated with the MDR service. We can integrate up to 3 DNS servers and 6 DNS. Search Domains per the CyberHub. DNS information is currently not shared between CyberHub(s).
When standing up an CyberHub server to connect to the Adaptive MxDR Platform, apply the following port settings:
Table - 1.2: Port Requirements
Source | Destination | Protocol/Port | Description |
<CyberHub IP> | TCP/443 | SSM Agent service for Adaptive MxDR management access | |
<CyberHub IP>
| <Customer NTP> | UDP/123 | Network Time Protocol |
<CyberHub IP> | TCP/443 | CyberHub Updates | |
<CyberHub IP> | TCP/443 | CyberHub configurations. | |
<CyberHub IP> | <Customer DNS Server> | TCP/53; UDP/53 | DNS resolution (TCP is used in case the message is longer than 512 Bytes) |
<CyberHub IP> | TCP/443 | To send logs to Chronicle instance. List of Chronicle URLs in link -Chronicle forwarder |
Configuration for Amazon Web service (AWS) using Cloud Formation
Login to AWS portal.
Enter CloudFormation in search bar, then select the CloudFormation service from the list.
Click Create Stack.
In Choose a template, click the Template is ready.
Select Template source as Upload a template file. Download the below attached json file and choose file under Upload a template file from local to upload.
This Cloud formation template will create CyberHub with encrypted EBS storage.
Provide the below mandatory details:
Enter the stack Name of your choice in Stack Name.
Enter the meaningful hostname for the instance in Hostname.
Enter the Instance name of your choice in the InstanceTag (Note: This Instance name will be used in Step 11).
Select any one Instance type as recommended below.
Family | Type | vCPUs | Memory (GB) | Instance Storage |
Compute optimized | c5a.2xlarge | 8 | 16 | EBS only |
Compute optimized | c5a.4xlarge | 16 | 32 | EBS only |
Enter your local NTP in NTP IP (Please provide only one IP address).
Select the Subnet (Select a subnet to host this instance)
Select the VPC (select a VPC to host this instance)
Click Next.
Skip the Options page and click Next.
Review the information and click Create.
Select the Stack Name checkbox and ensure the Status field value appears as CREATE_COMPLETE.
Click on the Services tab and select EC2.
Click on Instances.
Search the keyword Name and then click on it.
Click Name under the Tag keys and supply the Instance Tag Name value provided in Step 6 and click on the Instance Tag Name (Example: CyberHub4.0)
Instance details will appear in the screen.
Share the Elastic IP address details to Accenture Adaptive MxDR team to proceed with the CyberHub qualification process.
