Understanding Microsoft Sentinel

At one time the idea of keeping data safe was keeping it in a secure location. However, with the advent and the subsequent growth of cloud computing, this mentality has evolved. Nowadays, up to 60% of all company data is stored in the cloud and more potentially sensitive data is transferred from off-premises to on-premises each day. However, the increase in cloud usage does not necessarily translate into increased cloud confidence – around 60 percent of security and IT executives aren’t completely certain of their company’s ability to protect crucial cloud access.

The unfortunate reality is that whether it’s stored on site or in the cloud, data of businesses is constantly under attack by ever-sophisticated cyber threats. In the same way there’s a lot at risk: loss of revenue and the disclosure of personal information about customers and business capabilities being diminished reputational damage, as well as penalties for failure to comply with regulatory requirements are all real-world consequences even for minor breaches. Therefore, companies in every industry require effective methods for quickly identifying and managing threats in every form and across the entire attack surface.

Microsoft Sentinel is designed to satisfy these requirements.

What exactly is Microsoft Sentinel?

Microsoft Sentinel (recently changed to Microsoft Sentinel) Microsoft Sentinel (recently renamed as Microsoft Sentinel) is an information security and event management (SIEM) system which also functions as an instrument for security orchestration as well as automation and response (SOAR). The Azure SIEM/SOAR service is an all-encompassing approach to security of data, providing a bird’s-eye overview of all aspects of your company, providing advanced security analytics that optimize security, detection of threats as well as proactive hunting and the ability to respond to threats.

Cloud-based and capable of scaling to meet any company’s evolving needs, Microsoft Sentinel is the culmination of years of experience in data security, utilizing the latest AI capabilities to provide modern businesses with more efficient, intelligent large-scale intelligence without the need to develop infrastructure in-house or incur maintenance expenses.

What is Microsoft Sentinel Do?

Microsoft Sentinel is a comprehensive method of protecting your company’s information. The single application aggregates data from every source across the enterprise that includes applications, users servers, cloud-based and on-premises devices.

In another way, Microsoft Sentinel is a completely integrated security system, with the following capabilities:

Collecting Data

Every aspect of your business generates data, and knowing that data is essential to establishing a solid security position. Microsoft Sentinel collects data from all sources of data, and uses Log Analytics, a Log Analytics tool to record pertinent events and other data to provide a thorough analysis.

Detection of threats

By placing your data under the microscope, Microsoft Sentinel applies Microsoft Analytics supported by continuously-evolving threat intelligence to detect any unidentified risks or suspicious activity in the system, while reducing the possibility of detecting false positives. If potential threats are identified security personnel are immediately alerted and threats are classified and categorized for assignment and investigation.

Investigating Threats

Making use of a Microsoft Sentinel Service allows you to take on the offensive and search for suspicious activity and analyzing threats with detailed analysis of data that is correlated with multiple sources. AI-enhanced capabilities allow you to expand threat analysis to any size business.

Responding to threats

If your data is under attack Every second is important. Microsoft Sentinel includes automation options and orchestration built-in, to provide immediate security capabilities.

What is what are the Elements of Microsoft Sentinel?

Although Microsoft Sentinel is a single, comprehensive security-intelligence solution, it is comprised of several different components. The nine main components include:


Advanced analytics within Microsoft Sentinel uses the Kust Query Language (KQL) to enable users to design custom alter conditions. Alerts are classified into “incidents” that represent possible threats that require investigation and resolution which reduces the amount of alerts that have to be examined in the hands of IT Security teams.


Based on the user-defined analytics, Microsoft Sentinel collects all relevant evidence from investigations into particular cases, and contains several alerts.


Microsoft Sentinel has a dedicated and active community that is centered around the GitHub Microsoft Sentinel community page. The community provides crucial resources for detections based on a myriad of data sources, as well as security playbooks, hunting queries and much more.


Data visualization is an essential component in Microsoft Sentinel; built-in dashboards let users easily look over the data’s aggregated insights in an instant.

Data Connectors

As part of the larger Microsoft environment, Sentinel integrates seamlessly with other Microsoft and Microsoft-partner solutions as well as products. This lets data be shared and integrated across different systems.


Microsoft Sentinel uses proactive threat analysis that is enhanced by AI and the machines-learning abilities of KQL to identify suspicious behaviour and increase its efficiency over time.


Integrations built-in to Jupyter Notebook give you access to libraries and modules that can be used for embedded analytics analysis of data machine learning, data analysis, and visualization. This improves the usability and expands the possibilities of using the data that is stored and collected.


If alerts are issued when alerts are issued, knowing the steps to take could make all the difference. Microsoft Sentinel includes playbooks detailing precisely what actions should be performed in response to specific security alerts. Azure Logic Apps enhance flexibility and personalization by enabling the users to automatically manage appropriate response tasks and workflows.


Microsoft Sentinel groups data and information about configuration from various sources into containers referred to as Log Analytics Workspaces. These Workspaces contain data storage location information and data isolation based on the rights granted to users and other.

What threats are thwarted By Microsoft Sentinel?

As a complete, single-stop SIEM/SOAR tool, Microsoft Sentinel is effective in detecting, investigating as well as responding to entire range of threat actors and cyber-attacks. However, while Sentinel offers reliable protection against botnets, phishing attacks, malware, and so on but it could be more crucial in defending against the latest and most advanced threats.

Microsoft Sentinel is a viable solution for:

Credential Stuffing

Security professionals continue to warn users to change their passwords. However, many users still use the same passwords for access to different accounts and devices, and are particularly at risk of bot-driven attacks on credential security aimed at taking login credentials. Sentinel detects the warning signs of credential stuffing as well as other identity-based attacks, locking out threats and alerting the response teams.

Remote Work Attacks

With the new hybrid-office and remote-work expectations for employees following the COVID-19 pandemic business information is no longer restricted to corporate networks and devices. Microsoft Sentinel extends vital security capabilities to remote workplaces and protects data in areas that are most vulnerable.

Double Extortion Ransomware

One of the biggest threats to security of data is the double extortion ransomware attack in which hackers gain control over the systems of an organization and require payment in exchange for giving access back to the legitimate owners. Microsoft Sentinel uses a correlation engine that is based on machine learning algorithms that can be scaled to determine if security alerts can be linked to ransomware-related activity.
