Using Host Indicators with SecurityCenter Step 1 – Filter Events by Host Step 2 – Perform Further Analysis Recommended Reading – Using Log Correlation Engine to Monitor DNSUsing Log Correlation Engine to Monitor DNS

Step 1 – Filter Events by Host

Step 2 – Perform Further Analysis See slides for Using ThreatConnect Address Indicators steps 5 through 9 if there are events found after applying filters. Filtering by the domain summary event before saving the asset list will get you a list of only those hosts that performed a DNS lookup for the host indicator.

Using URL Indicators with SecurityCenter Step 1 – Divide Host and Location from URL Step 2 – Filter Events by Host Step 3 – Save Asset List Step 4 – Filter Events by Location Step 5 – Perform Further Analysis

Step 1 – Divide Host and Location from URL

Step 2 – Filter Events by Host Use Host in Syslog Text filter Use web-access in Type filter If there arent events after applying filters theres no need to continue with further steps.

Step 3 – Save Asset List

Step 4 – Filter Events by Location Use Location in Syslog Text filter Use Asset List in Source Asset filter If there arent events after applying filters theres no need to continue with further steps.

Step 5 – Perform Further Analysis See slides for Using ThreatConnect Address Indicators steps 5 through 9 if there are events found after applying filters. We will be creating a second and final asset list to use for further analysis. Verify the URL is matched correctly by looking at the web-access details in Step 4. Steps 1 through 4 perform an intersection; however, its by host.
