Based on the findings of the QuickView mid-year report published by Risk Based Security, 2019 was an important year concerning the issue of data privacy breaches. The report states that infringements and data breaches in 2019 were 52 percent higher than in 2018 [1]. The Internet of Things (IoT), the incompetent staff, the integration of cloud infrastructure, and the rapidly shifting cyber threat environment are responsible for the effectiveness of these cyber-attacks. These were the reasons why Microsoft announced the release of its Security Information and Event Management (SIEM) solution with the Azure Sentinel platform.

Azure Sentinel is a Security Orchestration, Automation, and Response (SOAR) cloud solution for native security information event management (SIEM). A SIEM software integrates data and analyzes security alerts in a real-time generated by apps and network devices. A SOAR solution automates security alert investigations and responses. IT professionals often combine SIEM and SOAR ‘s capabilities as they prefer to work together to protect organizational data. Traditionally, however, these are two distinct products or components. In order to accommodate both SIEM and SOAR, Microsoft built Azure Sentinel.

What is Azure Sentinel

Microsoft Azure Sentinel is a modular and scalable cloud-based SIEM (Security Information Management) and SOAR (security orchestration automated response) solution. Azure Sentinel provides the organization with a singular and streamlined approach for the monitoring of warnings, identification of threats, proactive hunting, and threat response. Azure Sentinel provides a bird’s eye view of the organization thus reducing the stress of increasingly complex cyber-attacks, increasing alert volumes, and long timeframes for resolving these threats and alerts.

Key Features and Benefits

Many organizations waste their time and energy in the design, operation, and maintenance of the infrastructure of their SIEM solutions. It’s very time consuming, therefore Microsoft has built a security framework based on Azure and AI that protects all cloud-based data, information, and on-premises apps to tackle this major issue. With Azure sentinel, there is no need to build or maintain any infrastructure and no upfront costs required as the users will pay only for what they are using. It is economical and very efficient in the collection, detection, analysis, and resolution of all types of threats or logs. AI quickly identifies and intelligently addresses major threats without the infrastructure and setup.

Azure Sentinel is based on Azure Log Analytics, which is capable of collecting data or information from different security logs, making it a manageable process. Microsoft 365 has the strongest recommended impact. Azure sentinel gathers information from different environments and can be deployed on platforms including:

  • Azure Information protection
  • Azure Identity protection
  • Advanced threat protection
  • Azure Information protection

Sentinel is also capable to be integrated with external applications such as Cisco ASA or multiple firewalls, and more solutions are still coming. Similar to Azure sentinel, custom connectors are not complicated, as it can operate with any input provided in Syslog format or the standard event format. The REST API available in Azure sentinel makes every other connector easy to implement.

Azure Sentinel has simple but prominent features including:

Integrated AI: Azure Sentinel integrates AI to focus quickly on real threats through machine learning capabilities. This is based on the daily signals of trillions of analysis and security breaches. AI helps you to collect, identify, analyze, and respond to threats effectively.

Cloud SIEM: The Azure sentinel Microsoft is a cloud-based sentinel with amazing skills that cover not only Azure but also other cloud resources. Data from Office 365, cloud security, etc. can also be analyzed.

Capture data on a cloud-scale: On-premise and in several clouds for all users, devices, applications, and infrastructure.

Detect undetected threats: Minimize false-positive results by leveraging analytics from Microsoft and unmatched threat intelligence.

Investigate threats using artificial intelligence: Hunt suspicion on a scale, drawing on years of Microsoft’s cybersecurity activities.

Respond rapidly to incidents: With built-in orchestration and common task automation.

Automated response: Azure sentinel supports automatic threat detection and responses, which keep the organization secure. It is a highly favorable choice because of the automated response feature.

Easy Installation: Azure SIEM tool is a perfect tool for security information and event management and does not even require complex installation. It has a very easy setup of infrastructure that doesn’t take too much time.

Deep Investigation: Azure Sentinel can quickly investigate threats beginning with cases that can be filtered by criteria. Sentinel’s hunting capability includes search and query tools which use multiple data sources to analyze and help detect issues.

How does it work?

First, devices and services need to start streaming their data over Data Connectors through Sentinel. The data flow theoretically into Azure Log Analytics. Workbooks are used to visualize the data, possible problems and patterns, and to help create detailed queries. These queries, called analytics, will help create rules. You start to see Incidents after creating analytical rules, as well as process automated acts through Playbooks. You can leave a trail of bookmarks to flag unusual or anomalous data for follow-up while analyzing incidents and find other areas that may be affected. Finally, you can go Hunting for threats after acquiring experience.

Azure Sentinel is practically a great alternative for cloud businesses and has many advantages. The main feature that makes it a good alternative is its artificial intelligence technology, which makes it easier to identify, capture, analyze, and respond to threats. It has an eagle eye across your organization and provides your data with the best possible security for an organization. When combined with current cloud systems, Azure Consultancy Teams explore the opportunities and advantages that Azure Sentinel has to bring. The Azure Sentinel may not be ready for production, but it offers motivation for taking Azure Log Analytics or increasing them. Azure sentinel is an affordable option for deploying a cloud-based SIEM framework with built-in AI for processing a vast amount of data on any network from apps, users, computers, and servers Azure Sentinel has a platform for creating new insights, threat intelligence and the detection of machine models for a company.
