Standardized Threat Indicators • Tenable Formatted Indicator Export • Adversary Analysis (Pivoting) • Private and Community Incident Correlation • ThreatConnect Intelligence Research Team (TCIRT) • Community Notifications
Slide Sections • Using Address Indicators with SecurityCenter • Using File Indicators with SecurityCenter • Using Host Indicators with SecurityCenter • Using URL Indicators with SecurityCenter • Using File Indicators with Nessus
Using Address Indicators with SecurityCenter • Step 1 – Export Address Indicators Using Tenable Format • Step 2 – Create a Watchlist from Address Indicators • Step 3 – Filter Events by Watchlist • Step 4 – (Optional) Create Query for 3D Tool • Step 5 – Save Asset List of All Addresses • Step 6 – Perform Audit Analysis Using Asset List • Step 7 – Perform Event Analysis Using Asset List • Step 8 – (Optional) Create List of Internal Addresses • Step 9 – (Optional) Nessus Audit of Internal Addresses
Step 3 – Filter Events by Watchlist Inbound or outbound If there aren’t events after applying filters there’s no need to continue with further steps.
Step 6 – Perform Audit Analysis Using Asset List Recommended Reading – Predicting Attack Paths
Step 7 – Perform Event Analysis Using Asset List Recommended Reading – Tenable Event Correlation
Using File Indicators with SecurityCenter • Step 1 – Export Hashes Using Tenable Format • Step 2 – Upload Hashes to Scan Policy • Step 3 – Perform a Scan Using Credentials • Step 4 – Review Scan Results • Step 5 – Save Asset List of Infected Hosts • Step 6 – Perform Audit Analysis Using Asset List • Step 7 – Perform Event Analysis Using Asset List • Step 8 – (Optional) Use Asset List with 3D Tool
Step 2 – Upload Hashes to Scan Policy Recommended Reading – Malware Detection and Forensics Scan Configuration
Step 3 – Perform a Scan Using Credentials Recommended Reading – Nessus Credential Checks for UNIX and Windows
Step 4 – Review Scan Results If there aren’t infected hosts there’s no need to continue with further steps.
Step 6 – Perform Audit Analysis Using Asset List Recommended Reading – Predicting Attack Paths
Step 7 – Perform Event Analysis Using Asset List Recommended Reading – Tenable Event Correlation
Using Host Indicators with SecurityCenter • Step 1 – Filter Events by Host • Step 2 – Perform Further Analysis Recommended Reading – Using Log Correlation Engine to Monitor DNS
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 2 – Filter Events by Host Use web-access in Type filter If there aren’t events after applying filters there’s no need to continue with further steps. Use Host in Syslog Text filter
Step 4 – Filter Events by Location Use Asset List in Source Asset filter If there aren’t events after applying filters there’s no need to continue with further steps. Use Location in Syslog Text filter
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, it’s by host.
Using File Indicators with Nessus • Step 1 – Export Hashes Using Tenable Format • Step 2 – Use Windows Malware Scan Wizard • Step 3 – Perform Scan and Review Results
