If you’re tired of reacting to alerts and are looking for ways to get proactive with your security posture, you might be considering threat hunting. Threat hunting is an active form of cyber defense that allows your team to proactively identify abnormal behavior or vulnerabilities and mitigate these before any harm is done. But how do you know what to hunt for? Knowing where to begin and what to look for can be the greatest challenge; that’s why we’ll be sharing a series of the threat hunting use cases we use, developed and refined over years and across different environments, to help you get started.
Think about going to the grocery store with a shopping list as opposed to going in with no list or plan in mind. You probably find that listing out your groceries and grabbing exactly what you need is far more efficient than searching the entire store for “something”. With no goals in mind you may leave the grocery store missing something important that you needed, leave with too much, or even find that you were not in a grocery store the entire time.
The practice of knowing your mission or defining your objectives is essential for every threat hunt campaign. In our Threat Hunting Use Case Blog Series, we’ll walk through some of the most common and critical threat hunt campaign objectives, covering log source requirements, expected outcomes, and sample analysis per use case. To kick off the series, we’ll start by covering the common threat hunting use case, “Firewall Targeting DNS.”
How do we decide what to hunt for? How do you identify similar threats or vulnerabilities that can be identified within the same dataset? How do we overcome difficulties with pulling data? Over the years we have developed a methodology to assist with answering these questions.
When developing a threat hunting use case, we look at tactics mapped to the MITRE ATT&CK framework and associate them to log sources that would output indicators of that attack. As an example for our Firewall Targeting DNS use case, Exfiltration Over Alternative Protocol (T1048) and Exfiltration over a Non-Standard Port (T1571) are mapped to Mitre ATT&CK and would be logged by a firewall. We call these “Threat Analysis” objectives or outcomes for our use case.
In addition to looking for actual attacks, we are also looking for the hygiene issues or weaknesses in security posture that lead to those attacks. This means we are looking for the active attacks while ensuring that the vulnerabilities that lead to them are patched which would prevent the attacks from occurring in the first place.
Objective: Direct client access to Internet DNS servers, rather than controlled access through enterprise DNS servers, can expose an organization to unnecessary security risks and system inefficiencies. This hunt involves reviewing DNS traffic captured by firewall logs in order to provide recommendations and findings focused on improving security posture related to outbound DNS queries and responses.
Log Source & Requirements: Firewall Allow & Firewall Deny from Application/Protocol-aware Firewall logs (Ex. Palo Alto, Cisco ASA, Checkpoint).
Duration: 30-90 Days
