# Aurora Endpoint Security (formerly Cylance PROTECT AV) Detection Strategy
## Product Overview
Aurora Endpoint Security is a next generation antivirus (NGAV) technology that consists of endpoint agents deployed to Windows, Mac, and Linux devices that check into a cloud console.\
\
The predictive AI model identifies and blocks malicious code in real-time without the need for constant signature updates. It is part of the broader Aurora Endpoint Security suite and includes endpoint detection and response (EDR) capabilities as well as AI-powered prevention. The platform offers a lightweight agent that minimizes system impact while providing robust protection against a wide range of cyberattacks.
## Detection Strategy for Endpoint Integrations
### Detection
Our endpoint detection strategy focuses on two common signal types: process and network events. By integrating directly with EDR vendors, we can process security alerts to extract evidence and normalize event details. These normalized signals are then processed through our detection engine to look for signs of post-exploitation activity.
In addition to categorical handling of vendors' security alerts, Expel maintains a large library of behavioral detections to augment vendor detections. When a threat is detected, our automated response bot, Ruxie, takes action by enriching evidence fields with first- and third-party threat intelligence. Additional Ruxie actions query a wide span of technologies directly to arm analysts with key pieces of investigative information and related events.
### Response
Endpoints provide rich context for processes and also support other types of Expel Alerts. For example, we use source device identification across a number of alert types when a source IP or hostname is available, because it provides rich context about the actor behind the activity.
Additionally, endpoints provide valuable information for network alerts to help identify what process triggered a connection.

## What We Support for Aurora Endpoint Security
To see a comprehensive list of the most up-to-date Expel detection rules, vendor detection rules, opt-in detections, and available DUETs (**d**id yo**u** **e**xpect **t**his) that we support for Aurora Endpoint Security, you can visit the [Detections page](https://workbench.expel.io/tools/detections/all?filter=%7B%22supportedTech%22%3A%7B%22is%22%3A%5B%22cylance_av%3A1.0.0%22%5D%7D%7D) in Workbench or ask your Sales or Support rep for the most recent download.
| **Supported platforms** | |
| ---------------------------------------------------- | ----------------------------------------------------------------------- |
| **Aurora Endpoint Security detection rules support** | Yes. |
| **Detection rules written by Expel** | Yes. |
| **Investigative support through Workbench** | No. We access the console directly with an "Investigator" role account. |

## Additional Details and Common Questions
### Console Access
A vendor alert does not typically include all of the contextual timeline activity surrounding the event of interest. Because this integration does not allow us to get all necessary data via the API, we will ask you for a certain level of console access during onboarding.
The level of access that we require is meant to support essential triage and research activities, and to help us determine the vector and extent of attacker activity for an identified threat. At minimum, we will ask for visibility into alert data, timeline events recorded, and live response/real time response shell (if applicable).
### DUET
A DUET (**d**id yo**u** **e**xpect **t**his) rule flags certain events as needing an immediate verification or notification, and bypasses the normal internal event triage process. The events subject to DUET rules contain behaviors that are not typically indicative of true security incidents, as they are related to policy violations or *potential* risk.
There are a number of workflows that a DUET may follow. When enabled, the activity will be flagged for investigation and will be routed to you (rather than to us) to take a specified first action. To see the specific DUET rules currently supported for this integration, visit the [Detections page](https://workbench.expel.io/tools/detections/all) in Workbench.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.expel.io/detection-strategy-guides/a-c/aurora-endpoint-security-formerly-cylance-protect-av-detection-strategy.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
