Monitor and alert Prioritize investigation + response with threshold based alerting Visualize and report Visualize long-term and historical trends; build reports and dashboards suited to any business, operational, or security need.

9 Security Investigation

10 Developing an Investigative Mindset What happened? Who was involved? When did it start? Where was it seen? How did it get in? How do I contain it? ALERT What specific questions do I want answered? What is the logic / methodology to apply? What s an example? Where do I look?

11 Investigative Mindset Questions to Ask What happened? Who was involved? When did it start? Where was it seen? How did it get in? How do I contain it? ALERT Question Logic Example Data Why did an alert trigger? Has a system actually been compromised? Search for events that match alert criteria and similar events leading up to the alert Find all failed authentication attempts by a user Endpoint logs Authentication logs Network logs Threat intelligence

12 Investigative Mindset Questions to Ask What happened? Who was involved? When did it start? Where was it seen? How did it get in? How do I contain it? ALERT Question Logic Example Data What accounts / users are associated with that system? Determine event to identity mapping John s account attempted to access a system it has never logged into before Identity system Authentication logs

13 Investigative Mindset Questions to Ask What happened? Who was involved? When did it start? Where was it seen? How did it get in? How do I contain it? ALERT Question Logic Example Data What does the timeline of activities leading up to and during the alert look like? Histogram and timeline Widen search to look over a wider set of historical data All Available Data

14 Investigative Mindset Questions to Ask What happened? Who was involved? When did it start? Where was it seen? How did it get in? How do I contain it? ALERT Question Logic Example Data What devices / assets are associated with the alert? Determine event to asset mapping IP has the hostname of DC-Seltzer, is a Windows 10 Workstation and has 2 critical vulnerabilities Endpoint Network devices CMDB/Asset

15 Investigative Mindset Questions to Ask What happened? Who was involved? When did it start? Where was it seen? How did it get in? How do I contain it? ALERT Question Logic Example Data Is there a logical connection to other activity, IPs, hosts, malware, or other alerts? Search network and host event logs to determine initial entry USB key opened an infected ransomware file, user indicates victim of spear phishing Endpoint Network devices Web proxy Mail proxy DNS Authentication

16 Investigative Mindset Questions to Ask What happened? Who was involved? When did it start? Where was it seen? How did it get in? How do I contain it? ALERT Question Logic Example Data Has the attack progressed beyond system infection? Identify whether malware has spread Observe indicators on other hosts or on the network Threat intelligence Endpoint Firewall Web proxy Mail proxy Wire data
