Companies often do not want to send some data sources to #Sentinel because they contain large amounts of data and are therefore expensive. But did you know that you can set up filters and collect only what you really need?

The so-called Data Collection Rules (#DCR) are used for this purpose. They are commonly used to filter, for example, specific event IDs within Windows Security Events.

But did you know that you can also use them to filter data from built-in connectors, typically from Microsoft Entra ID for example? https://techcommunity.microsoft.com/blog/microsoftsentinelblog/save-money-on-your-sentinel-ingestion-costs-with-data-collection-rules/4270256

La province de Valence le 31 octobre à 18h02 UTC par un satellite #Sentinel : les zones directement touchées par les inondations en bleu et les zones présentant des traces d'inondation résiduelles indiquées en vert clair.
La carte révèle que plus de 53 000 hectares ont été touchés par les inondations, avec plus de 190 000 personnes et 3 200 km de routes potentiellement touchées.

Coming soon: short article of my opinion on how to write clean KQL for Analytic Rules.

The article provides a comprehensive guide on how to use Bicep, a domain-specific language that uses declarative syntax to deploy Azure resources. It offers advantages over Azure Resource Management (ARM) templates such as smaller file size, integrated parameter files and better support for tools like Visual Studio code. The author explains in detail how to create a Microsoft Sentinel instance using Bicep templates, including setting up parameters, creating the Log Analytics workspace and deploying solutions via PowerShell scripts.

If you're interested in learning more about using Bicep for Microsoft Sentinel deployment or looking for tips on how to optimize your usage of this powerful tool, check out the full article. You'll find detailed examples of code snippets and useful links to further resources.

As digital environments expand, Security Operations teams are often faced with the challenge of optimizing costs while dealing with an exponential increase in data. This article outlines a strategy to reduce data volume and retain important information using Data Collection Rules (DCRs). The authors discuss how to decide what's important in a log for your organization and demonstrate the process of using DCRs to discard unnecessary information from logs. They also caution that only you can decide what’s essential for your organization in a particular log or table.

The authors delve into two types of DCRs: standard and workspace, explaining their use cases. They then guide readers on identifying high-volume sources, determining high-volume tables, record level analysis, column level analysis, and examining the process using two examples – AADNonInteractiveSigninLogs and SecurityEvent. In conclusion, they emphasize that as digital footprints grow exponentially, it is increasingly crucial for security teams to be judiciously intentional about the data they collect and retain. To learn more about this strategy and its application through practical examples, read the full article.

Some Sentinel users have noticed that several data connectors they were using are now showing as deprecated in the user interface. However, this change doesn't mean your data has stopped flowing; it's still being delivered to the CommonSecurityLog or Syslog table and analytic rules are still applying to the data. The deprecation is due to a switch from log analytics agent (MMA or OMS agent) to Azure Monitor Agent (AMA), which provides benefits like faster performance and support for multihoming.

The new AMA allows you to use a single connector, such as Common Event Format for AMA, instead of multiple different ones based on specific solutions. If you've already shifted to the Common Event Format data connector and want to delete the deprecated connectors, be aware there's currently an error preventing this but a fix is coming soon. To learn more about these changes and how they could benefit you, check out the full article.

The article discusses the Use Case Mapper Workbook, a tool that can help identify gaps in your Sentinel environment and established Content-Hub-Solutions. The workbook maps common use cases to the Mitre ATT&CK framework, providing an overview of available analysis options in Sentinel. It identifies several use cases such as Credential Exploitation, Lateral Movement, Rapid Encryption among others. The workbook also allows for customization by reducing results to selected Data Sources.

The post further provides a step-by-step guide on how to deploy and get started with the Use Case Mapper Workbook. It outlines prerequisites like having an Azure subscription with a Sentinel equipped Log Analytic Workspace and correct RBAC roles assigned. Once deployed, it explains how you can select predefined use cases and data sources/solutions within the workbook for your specific needs. To learn more about this invaluable tool that simplifies supplementing solutions for complete implementation while staying updated on new hunting queries, analytic rules or workbooks, check out the full article.

The article discusses Cowrie, an advanced honeypot designed to emulate SSH (Secure Shell) and Telnet services to attract, detect, and analyze malicious activities. As a cybersecurity tool, Cowrie creates a controlled environment that mimics real systems to lure attackers. It logs their activities in detail, providing valuable insights into their methods and motives. The features of Cowrie include SSH and Telnet emulation, detailed logging of attempted commands, file and command logging for comprehensive view of attacker's activities among others.

Cowrie is beneficial as it provides threat intelligence by observing interactions with the honeypot; detects unknown threats not caught by traditional security measures; improves security posture based on data collected from the honeypot; and offers low risk deployment since any malicious activity targeting the honeypot does not affect actual production systems. Integrating Cowrie with Microsoft Sentinel enhances cybersecurity operations through intelligent security analytics across the enterprise. To learn more about how you can utilize this powerful tool for your organization's cybersecurity needs or if you're interested in installing Cowrie on Linux or leveraging Microsoft Sentinel with Cowrie, check out the full post.
