Advanced Threat Analytics

Modern security teams cannot rely only on the logs data to find out potential attacks. We need more information than just what error was triggered, and internal logs will not provide that data for us. The Advanced Threat Analytics (ATA) feature in Log360 Cloud pulls data about malicious IPs, and domains that have an assigned reputation score and uses that to alert the administrators of any suspicious IP tries to connect to your network.

To enable Advanced Threat Analytics, follow the steps below:

1. Login to the Log360 Cloud application with Admin permissions.
2. Go to the Settings → Admin → Management → Threat Management → Advanced Threat Analytics.
3. Log360 Cloud provides you with two options to choose from,

Default Threat Server

When Enabled, Log360 Cloud correlates the information available in AlienVault OTX to trigger alerts if there's a match. This option only fetches data on the blacklisted IPs.

Advanced Threat Analytics

Overview

This option allows Log360 Cloud to provide more context about the potential attack by correlating crucial data such as the first and last time it was detected, reputation score, etc from the threat feed.

1. Log360 Cloud supports the following vendors for the Advanced Threat Analytics data:
   • Log360 Cloud Threat Analytics

     Default integration from Log360 Cloud suite. This can be accesed once the add-on is purchased.

   • VirusTotal

     Third-party threat feed integration. This follows the Bring Your Own Key(BYOK) model. If you have bought VirusTotal access separately, you can use your API key and get the threat analytics information in Log360 Cloud.

2. Access
   • Investigation: The Threat Analytics information can be accessed through the External Threat report and the Incident Workbench for investigations.
   • Detection: The Default Threat alert criteria detects interaction with external threat sources. Once the Advanced Threat Analytics add-on is applied, the alerts will be accurately fine tuned to reduces false positives.

External Threat report

The External Threat report contains the information on the source of the threat, severity, reputation score, and more.

• View reports of Top Attacked Hosts and Threats by Category for the selected period.



• Click on IPs in the Threat Source column and select Go To Incident Workbench to get contextual risk data from the integrated threat feeds

Setting Alerts for External Threats

1. From the Alerts tab, go to Manage Profiles -> Add Alert Profile.
2. When required to select an alert, choose Threat Analytics as the Alert Log Type and select the External Threat radio button and click Save.
3. Log360 Cloud will send an alert whenever a malicious IP tries to connect with your network.
