A critical component of any security operations team’s job is to deliver high-fidelity detections of potential threats across the breadth of adversary tactics. But increasingly sophisticated threat actors, an expanding attack surface, and an ever-present cybersecurity talent shortage make this task more challenging than ever.
Google keeps more people safe online than anyone else. Individuals, businesses and governments globally depend on our products that are secure-by-design and secure-by-default. Part of the “magic” behind Google’s security is the sheer scale of threat intelligence we are able to derive from our billions of users, browsers, and devices.
Today, we are putting the power of Google’s intelligence in the hands of security operations teams. We are thrilled to announce the general availability of curated detections as part of our Chronicle SecOps Suite. These detections are built by our Google Cloud Threat Intelligence (GCTI) team, and are actively maintained to reduce manual toil in your team.
Our detections provide security teams with high quality, actionable, out-of-the-box threat detection content curated, built and maintained by Google Cloud Threat Intelligence (GCTI) researchers. Our scale, and depth of intelligence, gained by securing billions of users everyday, gives us a unique vantage point to craft effective and targeted detections. These native detection sets cover a wide variety of threats for network and beyond, including Windows-based attacks like ransomware, remote-access tools (RAT), infostealers, data exfiltration, and suspicious activity.
With this launch, security teams can smoothly leverage Google’s expertise and unique visibility into the threat landscape. This release helps understaffed and overstressed security teams keep up with an ever evolving threat landscape, quickly identify threats, and drive effective investigation and response. With this new release, security teams can:
- Enable high quality curated detections with a single click from within the Chronicle console.
- Operationalize data with high-fidelity threat detections, stitched with context available from authoritative sources (such as IAM and CMDB).
- Accelerate investigation and response by finding anomalistic assets and domains with prevalence visualization for the detections triggered.
- Map detection coverage to the MITRE ATT&CK framework to better understand adversary tactics and techniques and uncover potential gaps in defenses.
Detections are constantly updated and refined by GCTI researchers based on the evolving threat landscape. The first release of curated detections includes two categories that cover a broad range of threats, including:
- Windows-based threats: Coverage for several classes of threats including infostealers, ransomware, RATs, misused software, and crypto activity.
- Network attacks: Secure workloads with additional coverage around exfiltration of data, suspicious behavior, and additional vectors.
Let’s look at an example of how you can put curated detections to work within the Chronicle dashboard, monitor coverage, and map to MITRE ATT&CK®.
An analyst can learn more details around specific detections and understand how they map to the MITRE ATT&CK framework. There are customized settings to configure deployment and alerting, and specify exceptions via reference lists.
You can see each rule which has generated a detection against your log data in the Chronicle rules dashboard. You can observe detections associated with the rule and pivot to investigative views. For example, here is the detection view from the timeline of an Empire Powershell Stager launch triggered by the Windows RAT rule set. You can also easily pivot to associated information and investigate the asset on which it was triggered.
By surfacing impactful, high-efficacy detections, Chronicle can enable analysts to spend time responding to actual threats and reduce alert fatigue. Our customers who used curated detections during our public preview were able to detect malicious activity and take actions to prevent threats earlier in their lifecycle. And there’s more to come. We will be delivering a steady release of new detection categories covering a wide variety of threats, community-driven content, and other out-of-the-box analytics.
