Introduction
Azure Sentinel, on the other hand, has been designed to help all enterprises with their security monitoring. It is designed to monitor both on-premises and cloud services. The Azure Sentinel tool can be used to manage the entire threat protection lifecycle.
Overview of Azure Sentinel
Azure Sentinel is a cloud-based security analytics platform that combines Azure Security Center and Azure Log Analytics to detect and investigate threats, as well as automate responses to them. It offers a variety of features including:
- Real-time alerts and notifications
- Automated investigation prompts
- Threat intelligence integration (including SIEM)
Use Cases of Azure Sentinel
The Azure Sentinel platform is designed to detect and prevent threats. You can use it to do the following:
- Identify risks in your network environment and make recommendations on how to mitigate them.
- Analyze a wide range of data sources to identify risky behavior or anomalous activity—such as an increase in failed login attempts against critical systems, unusual amounts of network traffic from devices that shouldn’t be communicating with each other, or suspicious IP addresses accessing your resources through a firewall rule—and notify you when specific events occur.
- Detect zero day attacks by inspecting for malicious content in files stored on servers or shared drives, such as Microsoft Office documents that contain macros that download malware onto computers running Word; SQL Server databases containing malware scripts; PowerShell scripts with embedded binaries; etc.
Section Data Sources in Azure Sentinel
Azure Sentinel can collect data from a variety of sources. The following table lists the sources that Azure Sentinel can collect data from and the types of data that it collects:
- Azure Cloud Services (ACS)
- On-Premises Servers
- Network Devices
Section Security Analytics in Azure Sentinel
Azure Sentinel is a cloud-based service that provides an integrated platform for security operations, security analytics and security intelligence. It is a unified platform for security operations, security analytics and security intelligence.
It helps you to monitor your environment continuously by collecting data from across on-premises and cloud workloads at scale. This data can be analyzed in real time with advanced analytics powered by machine learning to provide insights into the overall health of your infrastructure. It also provides an easy way to get actionable information out of all this data through dashboards or alerts via its notification engine so you can take preemptive actions before any risk occurs in your environment
Investigate Threats in Azure Sentinel
The Azure Sentinel is a cloud-based platform that provides you with the ability to investigate your threats. It offers an all-in-one approach for analyzing and investigating security events, analyzing network traffic, and detecting malware in your cloud environment by using machine learning models.
The following are some of the use cases of Azure Sentinel:
- Attack analysis
- Vulnerability management
Automate responses with playbooks in Azure Sentinel
Playbooks are a set of steps to be executed in the event of a threat, alert or investigation. Playbooks can be created by users, groups or roles and they can be used to automate responses to threats.
For example, if an Azure Sentinel user receives an alert about ransomware activity on their infrastructure and wants to automatically remediate it using Azure Security Center, they could create a playbook that has the following steps:
- Launch an investigation with Azure Security Center’s (ASC) Threat Hunting feature via ASC’s API.
- Identify suspicious actions like lateral movement across multiple VMs within their virtual network (VNet).
- Stop any suspicious processes running on compromised machines within their VNets as well as machines that have not been compromised but may become so shortly through lateral movement techniques such as file transfer protocols (FTP), Remote Desktop Protocol (RDP) share access and others.
Create Cases in Azure Sentinel manually
You can create cases manually, or automatically by using a playbook.
- Manual: In this case, you will be responsible for creating the case manually and updating it periodically. You may want to use this option if you already have a security solution in place but are transitioning from another platform, or if your organization has not yet implemented an enterprise-wide SIEM solution.
- Playbook: PowerShell scripts that automate the process of creating a case from various sources (such as endpoint logs) and adding it to Azure Sentinel so that it can be analyzed by security analysts in real time. Playbooks provide an efficient way of turning thousands of data points into meaningful information about attacks against your organization’s assets by running through all these steps automatically—without having to do anything on your end after completing them once!
Threat Intelligence in Azure Sentinel
Threat intelligence is an important part of the mitigation process and detection process. Threat intelligence is a critical aspect of any cybersecurity program, and it can be used in different ways to improve your threat protection. You can use threat intelligence in the following areas:
- Mitigation: Threat intelligence will help you to detect, analyze and respond to cyber threats more efficiently by providing insights into attacker behaviors, methods and tactics. As a result, you will have more options during an attack so that you can make decisions faster with greater confidence in their validity. This allows you to take appropriate action against attacks before they are successful or cause damage within your organization’s systems or assets.
- Detection: Using cyber threat intelligence services helps organizations detect cyber threats earlier because these organizations employ advanced analytical capabilities that enable them to identify patterns that may lead up towards an attack on their networks based on what has happened in past cases involving similar situations (i.e., malware infections). This enables security teams at organizations using these services from vendors like Microsoft Azure Sentinel Service provide early warning alerts about possible attacks so that their customers can take necessary actions before something bad happens (such as getting hacked).
Prevention and Detection using Azure Sentinel
Azure Sentinel is a security service that helps detect threats and prevent attacks. It provides a single pane of glass to analyze, investigate, and respond to threats. Azure Sentinel’s components include:
- Sentry – Provides real-time threat detection capabilities by using machine learning algorithms to detect anomalies in your network traffic or logs. Sentry uses a variety of techniques, including anomaly detection, behavioral analysis, and data loss prevention.
- Forensics – Enables you to collect forensic evidence from compromised endpoints to help with incident response activities such as malware analysis and forensics investigations. The collected data can be analyzed in the context of time based events across multiple devices on various networks via the Azure Security Center portal or its APIs.
- Investigation Hub (IH) – Provides an integrated view into all machines connected through IH for easy access to all collected information related to attacks for quick investigation purposes without having them separated due to different sources being used during collection process (e.g., firewall logs versus antivirus logs).
Microsoft has launched the new tool known as the Azure Sentinel. It can be used for the prevention of threats and the detection.
- Azure Sentinel is a new tool launched by Microsoft. It can be used for the prevention of threats and the detection.
- Azure Sentinel is available in the Azure Cloud as a cloud-based platform that provides security analytics to monitor and detect threats within an organization’s environment.
- It is designed to provide complete visibility into your data center, cloud environment and hybrid system landscape, allowing you to see attacks or vulnerabilities earlier with less false positives than existing solutions on the market today
