How Azure Sentinel can help you secure your cloud environment
Azure Sentinel is a cloud-native security information and event management (SIEM) solution that provides intelligent security analytics and threat detection across your entire enterprise. Whether you have on-premises, cloud, or hybrid infrastructure, Azure Sentinel can help you collect, analyze, and respond to security events from various sources.
In this article, we will explore some of the key features and benefits of Azure Sentinel, and how it can help you simplify your security operations and reduce costs.
Collect data at cloud scale
One of the challenges of traditional SIEM solutions is that they require a lot of infrastructure setup and maintenance, and they often have limitations on storage and query capacity. This can hinder your ability to collect and process all the relevant data for your security needs.
Azure Sentinel solves this problem by being a fully managed service that runs on Azure. You don't need to worry about provisioning servers, scaling resources, or updating software. You can connect to hundreds of data sources, including Microsoft solutions like Microsoft 365 Defender, Microsoft Defender for Cloud, Office 365, Azure Active Directory, and more. You can also integrate with non-Microsoft solutions using common event format, Syslog, or REST-API.
Azure Sentinel allows you to collect data at cloud scale, across all your users, devices, applications, and infrastructure. You only pay for the data you ingest and store, and you can take advantage of Azure's global network and security capabilities.
Detect threats with AI and threat intelligence
Another challenge of traditional SIEM solutions is that they often generate a lot of noise and false positives, making it hard to identify and prioritize real threats. They also rely on manual rules and signatures that can quickly become outdated or irrelevant.
Azure Sentinel leverages artificial intelligence (AI) and machine learning (ML) to analyze billions of signals across your enterprise and detect anomalies and patterns that indicate malicious activity. Azure Sentinel also incorporates Microsoft's unparalleled threat intelligence, which is based on analyzing trillions of signals daily from various sources like Windows Defender Antivirus, Microsoft 365 Defender, Azure Defender, Microsoft Threat Intelligence Center, and more.
Azure Sentinel helps you reduce noise and false positives by providing a prioritized list of alerts that are correlated and enriched with contextual information. You can also use built-in or custom queries to proactively hunt for suspicious activities at scale. Azure Sentinel enables you to detect previously undetected threats and respond faster and more effectively.
Respond to incidents with automation and orchestration
The final challenge of traditional SIEM solutions is that they often require a lot of manual effort and coordination to investigate and respond to incidents. This can result in slow resolution times, human errors, and missed opportunities to contain or prevent attacks.
Azure Sentinel simplifies incident response by providing a unified view of the entire scope of every attack. You can use interactive dashboards and workbooks to visualize the attack chain and drill down into the details. You can also leverage Azure Logic Apps to automate and orchestrate common tasks such as sending notifications, creating tickets, blocking IPs, isolating devices, running scripts, and more.
Azure Sentinel helps you respond to incidents rapidly and efficiently by reducing the need for manual intervention and streamlining your workflows. You can also use Azure Sentinel's built-in or custom playbooks to codify your best practices and ensure consistent and effective response actions.
Azure Sentinel is a cloud-native SIEM solution that provides intelligent security analytics and threat detection across your entire enterprise. It helps you collect data at cloud scale, detect threats with AI and threat intelligence, and respond to incidents with automation and orchestration. Azure Sentinel helps you modernize your security operations center (SOC) and reduce costs compared to legacy SIEM solutions.
