Microsoft Sentinel - Business Considerations

Cost Management

Cost management is an integral part of an organization's risk management where Microsoft Sentinel creates analytic rules for detecting an attacker's behavior with the help of the data provided to it. However, every bite of the data ingested into Log Analytics carries a cost which implies that one should come up with some knowledge or ideas to build as well as evaluate a business case for adopting Microsoft Sentinel. Some of them are discussed below:
  • Evaluating Your Data Ingestion Against Use Cases- A cost-effective analysis is highly required for the ingestion of different types of log data that may lead to extra costing in your Microsoft Sentinel deployment. It is recommended to recognize the high business risk applications with the of project teams that can survey and easily analyze the log volume or anticipated risk mitigation. Naturally, a high volume of log data with a relatively small number of potential risk issues can be excluded from Microsoft Sentinel budget after discussing with the stakeholders and decision makers to take the final call.

  • Log Ingestion Strategies- Due to the increase in the number of internet users along with the introduction of various linking devices like mobiles, SaaS, Internet Of Things (IOT), etc. the malicious activities of the threat actors have increased, and to cover all this, the "log everything" approach generally either leads to unmanageable costs or poor performance via quickly overwhelmed SIEM solutions. Hence, it is recommended to identify and analyze each type of log source in detail as well as their cost vs benefits of ingestion while considering all the important aspects for a fruitful result.

  • Budgeting For Microsoft Sentinel Costs- Microsoft Sentinel may prove highly cost-effective if proper attention is given to the cost management as it offers various benefits over physical and premises-based virtualized solutions, but, since there is a shift of IT infrastructure to cloud, all the assumptions and modes of operations for on-premises world should be re-examined and potentially adjusted. 

  • Ongoing Cost Monitoring & Evaluation- Regularly monitor the costs for log ingestion on an ongoing basis is very vital in making sure the ongoing viability of Microsoft Sentinel platform for an organization.

  Azure Sentinel Workbooks Several ready for use templates are provided by the Azure Sentinel that can be used to create your own workbook and then modify them as needed for Contoso. Most of the data connectors it uses to ingest data come with their own workbooks, but better insight can be obtained by simply looking into the data that is being ingested by using tables and visualizations, including bar and pie charts. You can also make your own workbook easily by using this data from the beginning instead of using the predefined templates. Workbook Page You can easily access the workbook page from the Azure Sentinel from the navigation pane which consists of the: Workbook header- You can add a new workbook and review the saved workbooks as well as templates that are available on the workbook page. Templates section- You can access existing workbook templates on the Templates tab. You can save some of the workbooks for quick access and they will appear on the My Workbooks tab.  From the

The loaf balancer also offers an option of DirectServerReturn which if configured, can help in directing the traffic from the DBMS VM to the SAP application layer directly to the application layer without routing through the load balancer. But, if it isn't configured, then the return traffic to the SAP application layer is routed through the load balancer. You can also use Azure Load Balan

Work with String Data Using KQL Statements

  Extract Data from Unstructured String Fields Unstructured string fields often contains the Security log data and requires parsing to extract data. There are multiple ways of pulling information from string fields in KQL and the two primary operators used are extract and parse.  Extract It gets a match for a regular expression from a text string. You can convert the extracted substring to the indicated type.  Arguments regex- A regular expression. captureGroup- A positive int constant indicating the capture group to extract. 0 stands for the entire match, 1 for the value matched by the first '('parenthesis')' in the regular expression, 2 or more for subsequent parenthesis.  text- A string to search. typeLiteral- An optional type literal. If provided, the extracted substring is converted to this type.  Returns If regex finds a match in text- the substring matched against the indicated capture group captureGroup, optionally converted to typeLiteral. If there's no mat
