- False
Answer: False.
Explanation: Azure Notebooks primarily leverage Python and R for creating and running hunting queries.
Interview Questions
What is Hunting in the context of Microsoft Security Operations?
Hunting, in the context of Microsoft Security Operations, refers to the proactive search for security threats that may not be automatically detected by security tools. It involves investigating directories, monitoring network traffic, and proactively searching for abnormal activities in server or application logs.
What is the purpose of using notebooks for hunting in Microsoft Security Operations?
Notebooks are used in hunting for providing a venue to record, document, and share findings. They provide a way to write, execute, and share code in an interactive environment which can help security operations analysts to perform threat hunting activities more effectively.
In the context of Microsoft Security operations, what is a notebook?
A notebook is an interactive programming environment that allows a user to execute code, view results, visualize data, and see computations. In the context of Microsoft Security Operations, notebooks are used for proactive threat hunting, information visualization, and sharing findings and methods with other analysts.
What is Azure Sentinel and how it is used in hunting?
Azure Sentinel is Microsoft’s cloud-native Security Information and Event Management (SIEM) solution. It uses built-in AI to analyze large volumes of data across an organization rapidly. It allows security analysts to create notebooks for hunting, providing capabilities for advanced threat detection, visualization, and response.
What is KQL and how is it used in notebooks for hunting in Microsoft Security Operations?
KQL, or Kusto Query Language, is a read-only request language used for querying large volumes of data. In hunting with notebooks, security analysts can use KQL to query and retrieve data for further analysis, helping in the identification of anomalies and potential security threats.
What is the use of Azure Notebooks in threat hunting?
Azure Notebooks provide an environment for writing, sharing and executing code in programming languages like Python and R. In threat hunting, Azure Notebooks can be used to run advanced analytics and use visualization tools, making threat detection, and investigation processes more efficient and collaborative.
What role does Microsoft Defender Advanced Threat Protection play in hunting threats using notebooks?
Microsoft Defender Advanced Threat Protection is a platform that helps enterprises prevent, detect, investigate, and respond to advanced threats. It assists in hunting by bringing in raw data for analysis into Notebooks and providing advanced threat intelligence.
How are Jupyter notebooks used in the context of Microsoft Security Operations?
In the context of Microsoft Security Operations, Jupyter notebooks can be used for running sophisticated queries, analyzing data, and recording the steps involved in a hunting investigation. It effectively captures the workflow of threat hunting, encouraging collaborative hunting and sharing of intelligence and techniques amongst analysts.
What are some common actions that can be performed in notebooks during the hunting process?
Some common actions include executing code, viewing output results, visualizing data, and documenting processes and insights. This can consist of querying data sources, performing investigations over historical data, exhibiting results graphically, and sharing the findings.
What are some of the features that make notebooks a useful tool in Security Operations hunting?
Notebooks allow for interactive analysis with visualisations which is crucial in investigating complex threats. They support multiple programming languages, can be shared for collaboration and ensure reproducibility of results. In addition, they contribute to the improvement of hunting processes by assisting in the development of templates for common investigations.
