# Microsoft Azure Kubernetes Service Detection Strategy

## Product Overview <a href="#h_01k0qbwz8tcxvnv6x7fjhnb7g0" id="h_01k0qbwz8tcxvnv6x7fjhnb7g0"></a>

Azure Kubernetes Service (AKS) is a managed container orchestration service offered by Microsoft Azure, designed to simplify the deployment, management, and scaling of containerized applications using Kubernetes. AKS offloads the operational overhead of managing the Kubernetes control plane to Azure, allowing developers to focus on building applications rather than managing complex infrastructure.  The service integrates natively with other Azure services for identity and access management, security, and monitoring. It provides features like automatic upgrades, node repair, and scaling to create a resilient and highly available environment for production workloads. AKS supports both Linux and Windows containers and can be used for various scenarios, from deploying microservices to running machine learning models at scale.

## Detection Strategy for Cloud Integrations <a href="#h_01jz3qmqgm1nbhesa4k4qwtdc7" id="h_01jz3qmqgm1nbhesa4k4qwtdc7"></a>

### Detection <a href="#h_01jz3qn0sc7st1b270cna7574h" id="h_01jz3qn0sc7st1b270cna7574h"></a>

Our cloud security detection strategy focuses on two common signal types at the control plane and resource levels: authentication events and API events. In limited cases, we also ingest certain data plane events such as network activity. We do this by integrating directly with cloud providers as well as cloud security service providers to gain a complete view of your cloud footprint.

We consume these events through a mix of raw log analysis and security alert processing, which are then run through our detection engine to look for signs of post-exploitation activity. 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 in order to directly arm analysts with key pieces of investigative information and related events.

### Response <a href="#h_01jz3qnewa93fnmsd4mqqgqx83" id="h_01jz3qnewa93fnmsd4mqqgqx83"></a>

In addition to verbose evidence collection for cloud alerts, cloud technologies are useful for triaging SaaS and identity alerts as well. User activities within the cloud providers, along with related alerts for anomalous indicators, help analysts gain a full picture of the activity that occurred within a session.

## Additional Details and Common Questions <a href="#h_01jz3r2q03bj8haj940pj1c8n4" id="h_01jz3r2q03bj8haj940pj1c8n4"></a>

### Console Access <a href="#h_01jz3r2tr0k5j43eypnfj1fqnb" id="h_01jz3r2tr0k5j43eypnfj1fqnb"></a>

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 href="#h_01jz3r3bafff9fztd7dfz6n3wf" id="h_01jz3r3bafff9fztd7dfz6n3wf"></a>

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).

## 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/d-m/microsoft/microsoft-azure-kubernetes-service-detection-strategy.md?ask=<question>&goal=<endgoal>
```

`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.
