This article describes the Security Orchestration, Automation, and Response (SOAR) capabilities of Microsoft Sentinel, and shows how the use of automation rules and playbooks in response to security threats increases your SOC's effectiveness and saves you time and resources.
SIEM/SOC teams are typically inundated with security alerts and incidents on a regular basis, at volumes so large that available personnel are overwhelmed. This results all too often in situations where many alerts are ignored and many incidents aren't investigated, leaving the organization vulnerable to attacks that go unnoticed.
The solution
Microsoft Sentinel, in addition to being a Security Information and Event Management (SIEM) system, is also a platform for Security Orchestration, Automation, and Response (SOAR). One of its primary purposes is to automate any recurring and predictable enrichment, response, and remediation tasks that are the responsibility of your Security Operations Center and personnel (SOC/SecOps), freeing up time and resources for more in-depth investigation of, and hunting for, advanced threats. Automation takes a few different forms in Microsoft Sentinel, from automation rules that centrally manage the automation of incident handling and response, to playbooks that run predetermined sequences of actions to provide powerful and flexible advanced automation to your threat response tasks.
Automation rules
Automation rules allow users to centrally manage the automation of incident handling. Besides letting you assign playbooks to incidents and alerts, automation rules also allow you to automate responses for multiple analytics rules at once, automatically tag, assign, or close incidents without the need for playbooks, create lists of tasks for your analysts to perform when triaging, investigating, and remediating incidents, and control the order of actions that are executed. Automation rules also allow you to apply automations when an incident is updated, as well as when it's created. This new capability will further streamline automation use in Microsoft Sentinel and will enable you to simplify complex workflows for your incident orchestration processes.
A playbook is a collection of response and remediation actions and logic that can be run from Microsoft Sentinel as a routine. A playbook can help automate and orchestrate your threat response, it can integrate with other systems both internal and external, and it can be set to run automatically in response to specific alerts or incidents, when triggered by an analytics rule or an automation rule, respectively. It can also be run manually on-demand, in response to alerts, from the incidents page.
Playbooks in Microsoft Sentinel are based on workflows built in Azure Logic Apps, a cloud service that helps you schedule, automate, and orchestrate tasks and workflows across systems throughout the enterprise. This means that playbooks can take advantage of all the power and customizability of Logic Apps' integration and orchestration capabilities and easy-to-use design tools, and the scalability, reliability, and service level of a Tier 1 Azure service.
Microsoft Sentinel uses automation rules to allow users to manage incident handling automation from a central location. Use automation rules to: Assign more advanced automation to incidents and alerts, using playbooks. Automatically tag, assign, or close incidents without a playbook.
Use Microsoft Sentinel playbooks to run preconfigured sets of remediation actions to help automate and orchestrate your threat response. Run playbooks automatically, in response to specific alerts and incidents that trigger a configured automation rule, or manually and on-demand for a particular entity or alert.
Microsoft Sentinel is a scalable, cloud-native security information and event management (SIEM) that delivers an intelligent and comprehensive solution for SIEM and security orchestration, automation, and response (SOAR).
There are four types of automation systems: fixed automation, programmable automation, flexible automation and integrated automation. Let's take a look at each type and their differences and advantages. Then you can try to determine which type of automation system is best for you.
A comprehensive and effective systematic approach to business process automation consists of 4 phases: analysis, implementation, integration, and maintenance and support.
Automation Rule: Set conditions to send Sentinel Incidents to an automation workflow or playbook.Playbook: Execute course of action (require API integrations with connectors). They are more complex and require deep knowledge.
Microsoft Sentinel is a cloud-native security information and event management (SIEM) platform that uses built-in AI to help analyze large volumes of data across an enterprise—fast.
Microsoft Sentinel can use agents provided by the Azure Monitor service (on which Microsoft Sentinel is based) to collect data from any data source that can perform real-time log streaming. For example, most on-premises data sources connect by using agent-based integration.
What do you dislike about Microsoft Sentinel? It integrates well with other microsoft products but users find challenges when they have to integrate with non-microsoft products. Users with non technical background finds it difficult to use Microsoft Sentinel. Also, cost is also a concerning point for the business.
Microsoft Sentinel is generally rated as being easier to use, set up, and administrate. Splunk generally gets better ratings for quality of support and ease of doing business. Most people trust Microsoft's products more, including its Network Management, Incident Management, and Security Intelligence.
Microsoft Defender also provides detailed threat intelligence. Azure Sentinel, on the other hand, is a cloud-native Security Information Event Management (SIEM) and Security Orchestration Automated Response (SOAR) solution.
One is owned by Microsoft, while the other is a standalone solution by SentinelOne. They provide different solutions regarding data protection and threat intelligence. Both are robust security solutions to help protect data. The way they protect against threats vary.
KQL is the query language used to perform analysis on data to create analytics, workbooks, and perform hunting in Microsoft Sentinel. Learn how basic KQL statement structure provides the foundation to build more complex statements.
Top Competitors and Alternatives of Azure Sentinel
The top three of Azure Sentinel's competitors in the Security Information And Event Management (SIEM) category are Splunk with 54.61%, IBM QRadar with 8.76%, Splunk Enterprise Security with 5.85% market share.
Put another way, cybersecurity automation streamlines manual and time-consuming tasks into automated workflows, making network security processes more efficient and less prone to human error. With enhanced efficiency, faster decisions can be made, which also can improve an organization's entire security posture.
Radiology workflow automation eliminates tedious and repetitive tasks, and frees up time for radiologists and technologists to focus on patient care. Automating the performance of quality control testing and data input allows radiologists to complete tests faster and move on to patient care.
What is firewall automation? Firewall rule automation is the process of automating firewall changes, provisioning, and policy tasks in order to strengthen security, assist in troubleshooting, reduce network bottlenecks, and ensure that organizations meet compliance mandates.
Infrastructure as code (IaC) is used for infrastructure automation to create environments. The most common use of IaC is in software development to build, test, and deploy applications. Traditionally, system administrators used a combination of scripts and manual processes to set up infrastructure environments.
