Deploying MMAs

Generally, MMA accumulates Windows Security, application, and system event logs along with the web server logs from Microsoft IIS and by deploying MMA on Linux will help in the collection of any syslog message or local logs that follows a consistent naming convention. In fact, any Linux agent installed with MMA can itself act as a syslog collector for the remote syslog log resources. 

Deploying Workbooks

Microsoft Sentinel workbooks offers various functions/applications like several visualization control, conditional formatting, several features of the analytical platform, etc. while it's also capable in retrieving data from multiple sources that might help in the complex integration of various Microsoft services, such as- Azure Log Analytics Workspace, Microsoft Graph, Azure Data Explorer, Azure Resource Manager, and whatnot. 

Deploying User & Entity Behavior Analytics (UEBA)

UEBA depicts the latest technologies of offered by SIEM solutions and generally rely on its machine learning abilities to keep track of the users and entities like hosts, IP addresses, etc., in order to detect as well as investigate any type deviations from the known pattern. Hence, UEBA proves helpful in collecting the various low fidelity signals to build a timeline of an event that can be further used in the better understanding as well as investigation of the entity behavior. 

Deploying Notebooks

Microsoft Sentinel Notebooks have proven very much helpful due to their advanced threat hunting abilities via the collected data as well as the processing capabilities available in many programming languages including but not limited to Python and C#/, .Net. 

Deploying Cyber Threat Intelligence (CTI) Functionality

CTI can be made available via various sources such as open-source data feeds, threat intelligence sharing communities, premium curated feeds, and your own security investigations. CTI when combined with your own data can offer valuable contextual information, that can majorly help in speeding-up the time used in detecting, identifying, and triaging malicious or anomalous activities. 

Deploying Alert Rules

The configuration of detection rules can be considered as the most important component of any Microsoft Sentinel deployments containing many built-in alert rules templates that can easily cover the whole array of a typical log source with continuous addition of new alert rules (that can be easily obtained via Microsoft Sentinel Community in which both the Microsoft as well as the third-party can publish new content). However, the proposed rules always go though community's review permitting only the valuable ones to be published in Microsoft Sentinel.

  To read part 1, please click  here To read part 2, please click  here Microsoft Monitoring Agent (MMA) MMA is used across multiple Microsoft solutions and has undergone a few name changes as its features and functionality have evolved. If it is being considered to be used, then following areas should be covered during a Microsoft Sentinel deployment project: Consider the timelines and the strategy for a migration to AMA (Azure Monitor Agent) before the MMA end-of-life.  Consider the central deployment and management methodology for MMA. Determine which endpoints are in scope for deployment as these affect the log ingestion volume significantly.  Azure Monitor Agent (AMA) Organizations with MMA as the main Microsoft Sentinel agent should start planning the migration to AMA as soon as possible to avoid a rushed migration. One of the main advantages of AMA is the ability to control the log collection policy centrally and apply different policies against different...

  To read part 2, please click  here To read part 3, please click  here Azure Resources Microsoft Sentinel needs following resources to be created: Subscription (if a dedicated subscription(s) will be used) Resource group(s) Log Analytics workspace(s) Automation rules/playbook Alert rules Workbooks Microsoft Sentinel offers hundreds of alert rules, workbooks, and automation playbook templates along with hunting scripts. The templates can be used to activate/deploy schedule alerts, create customized dashboards, create automation playbooks and perform threat-hunting activities. Generally, once deployed, the resources created have to be adjusted to match the existing environment, configure local credentials, etc. Methods of deployment: Manual- Administrator can manually configures the Microsoft Sentinel resources with the help of Azure portal. Any manual process has the inherent risks of human operator error, lack of compliance with potential change control procedures, and u...

  To read part 1, please click  here Engineering - SIEM The SIEM engineers configures Microsoft Sentinel, including Log Analytics, Logic Apps, workbooks, and playbooks. They are also responsible for the following high-level tasks: Initial configuration of Azure tenant, including provisioning required resources, assigning access roles, and configuring workspace parameters like log retention, resource tagging, and blueprints.  Deployment and configuration of syslog/CEF log collection agents in appropriate locations to collect logs from on-premises devices. Generally, it will be joint effort of both system engineer and SIEM engineer, involving configuration and potential troubleshooting.  Working with system owners to enable log forwarding and configuring any required parsing of log data in Log Analytics.  Working with security operations to create and deploy KQL analytic rules to offer detections for SOC/Computer Security Incident Response Team (CSRIT) use.
