A SIEM (Security Information and Event Management) and Security Orchestration and Automated Response (SOAR) system is called Azure Sentinel, and it is part of Microsoft’s public cloud platform. It can offer a unified solution for threat visibility, alert detection, proactive hunting, and threat response. It gathers information from several sources, does data correlation, and Data Visualization the processed information into a single dashboard. In order to gather, detect, look into, and address security risks and occurrences, Azure Sentinel is used.
Azure Sentinel stages
Gather Data
Azure Sentinel is capable of gathering information on all people, gadgets, programmes, and infrastructure in both on-premises and various cloud environments. Right out of the box, it can effortlessly connect to security sources. For Microsoft solutions, there are numerous connectors that offer real-time integration.
It also has integrated connections for goods and services from third parties (non-Microsoft Solutions). Aside from this, the necessary data sources can also be connected to Azure Sentinel via Common Event Format (CEF), Syslog, or REST-API.
Discover Threats
Azure Sentinel uses analytics and threat intelligence obtained directly from Microsoft to identify threats and reduce false positives. Correlating warnings to issues found by the security team is made possible in large part by Azure Analytics. It offers pre-built templates that may be used right away to develop threat detection rules and automate threat reactions. In addition, Azure Sentinel makes it possible to develop unique rules.
Respond
Azure Sentinel has the ability to look into and track down suspicious activity anywhere. It aids in noise reduction and security threat detection using the MITRE framework. Utilize artificial intelligence to proactively spot dangers across the protected assets before an alert is triggered to spot shady activity.
Observe Suspicious Activity
Instances of built-in orchestration can be handled by Azure Sentinel with ease and speed, and routine and frequent tasks may be converted to automation with ease. Playbooks can be used to provide streamlined security orchestration. When an event happens, it can also create tickets in ServiceNow, Jira, etc.
Top 2 Benefits of Azure Sentinel:
-
Aggregation of Data : SIEMs centralise data collection in a single pane of glass by collecting security event information from the whole network. Collecting security information from devices, users, apps, servers on any cloud, and other elements of your hybrid company is simple with Azure Sentinel. By reducing the need to spend time setting up, maintaining, and scaling equipment, it liberates you from the load of traditional SIEMs and ensures that you are swiftly recognising serious threats. It can meet your security demands with practically limitless cloud size and performance because it is based on Azure.
-
Normalization of Data : SIEM solutions standardise data in addition to collecting it. In other words, they reformat the data in the desired format, enabling easy correlation in addition to uniformity in log management. Azure Sentinel makes use of Azure Monitor, which is based on a tried-and-true log analytics database that can handle daily data input of more than 10 petabytes and has a lightning-quick query engine that can quickly sort through millions of entries.
