Project Planning

There are following key points that should be kept in mind during the project planning stage because they affect a project's duration:

  1. Access to log sources, system, and data owners.
  2. Types of log sources (such as, standard data connectors versus custom development).
  3. Complexity of Azure architecture (like, multiple tenants, cross-tenant searching).
  4. Requirement for custom SOAR automation playbooks, and interaction with other connected systems.
  5. Azure cost assessment and optimization strategy.
  6. Customer change management processes.

Main roles required for a successful Microsoft Sentinel deployment include:

  1. Project Manager
  2. Security Architect
  3. Cloud Engineer
  4. Engineering - systems owner
  5. SIEM Engineer
  6. Network Engineer
  7. Business Analyst
  8. SOC Analyst
  9. Developer (languages vary, but C#, Java, and Python are often beneficial)
  10. Compliance manager

Project Manager

It is recommended to have an experienced project management staff with Project Management Professional (PMP) and Information Technology Infrastructure Library (ITIL) backgrounds. It is because the stakeholder management requirements can be quite broad. The projects of Microsoft Sentinel will require input and work effort from teams supporting both cloud and on-premises infrastructure, end-user-facing services like SaaS applications and workstations, as well as mission-critical server infrastructure. 

Security Architect

There are numerous ways to gain security visibility to assets in the organization's information technology environment, but log ingestion from these sources must always be accompanied by analysis of the cost impact of ingestion and analysis of data. The Microsoft Sentinel environment will always contain highly sensitive data, and appropriate role-based access control must be applied to the Azure resources in scope of the project. The security architect will have the responsibility for the security design of the Microsoft Sentinel solution. 

Cloud Engineer

Microsoft Sentinel is very likely one of the many services running on an organization's Azure tenant. Hence, the organization's Azure cloud engineer/administrator will determine the resiliency requirements, Azure regions, data residency, and required tagging or templates applicable to Microsoft Sentinel. The engineer may also deploy various Azure policies that might help in the configuration of logging for multiple Azure resources. 

Engineer - Systems Owner

Log structuring and format may vary from source to source, and organizational owners of assets like SaaS applications, workstations, servers, cloud endpoints, and security infrastructure are often widely distributed. Hence, Subject Matter Experts (SMEs) and asset owners with administrative ability to offer samples of logs and configure log-forwarding parameters on each asset are required to dedicate effort to working with the project team to make sure that the data is sent to Microsoft Sentinel.

Conclusion

Here are some initial views of the key components of Microsoft Sentinel to provide an overview.

Query, Visualize, & Monitor Data in Azure Sentinel

  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
