An introduction to Azure Sentinel
In recent years, Security Information and Event Management (SIEM) solutions have been a rage in the cybersecurity domain. This is because SIEM solutions give you a comprehensive view of different components of the network such as your applications, antivirus, workstations, servers, databases, and more. They allow IT administrators to read between the lines and correlate events across the network. Microsoft's Azure Sentinel is an SIEM solution that comes with the added advantage of integrating all of Microsoft's Azure services, third party solutions, and network component, such as firewalls, syslog devices and more.
Understanding what Azure can do.
- Azure's dashboard provides a bird's eye view of your entire network. The tool bar in particular, offers a simple consolidated view of the number of events and alerts within a time frame. You also have a customized dashboard option that allows you to keep track of role-based authorization. This way users can only view what they're authorized to view on the dashboard.
- Azure uses machine learning to identify patterns in user behavior, and logs suspicious IP addresses. It also checks if alerts are related to each other. For example, a suspicious file activity that is also associated with a malicious IP address could pose a bigger risk.
- Azure Sentinel provides a 'Playbook' feature which allows you to setup automated procedures to deal with different security situations. An example of using the 'Playbook' feature is sending a security alert if any malicious IP address is detected trying to access your network. You can set up the alert to be sent to your security administrator. The administrator can choose to block the IP address. Azure Sentinel then sets up a firewall so the IP address cannot access your network.
- Azure allows you to perform deep investigations into security incidents that have occurred. Each incident is presented in the form of a case. You can access these cases individually from the dashboard. Cases can be sorted based on severity and status. The case shows you what kind of alerts were generated in response to a security incident, and why it was generated. It gives you detailed information on the list of entities such as user, computer or router that are associated with a particular incident. You can view a timeline of events, that led up to the security incident so you can conduct a detailed forensic investigation.
- Azure also provides search and query tools based on the Azure Log Analytics query language. You are also provided with a list of predefined queries associated to changes to an admin group, suspicious DNS requests, and more.

- Monitor Active Directory in real-time: Get comprehensive view of your Active Directory to detect any AD-based attacks, spot signs of lateral movements, identify suspicious user logons, monitor changes to AD objects such as GPOs, OUs, ACLs, and more, and analyze account lockouts all from one place.
- Correlate security incidents: Put together different yet relevant security incidents happening within your network to get the holistic attack picture using the real-time correlation engine. Get instant alert on the first signs of sophisticated attacks such as MailTo ransomware to prevent the attack from happening further and thereby reducing the damage.
- Manage security incidents: With the end-to-end security incident management platform, detect security incidents, automatically assign them to the security analyst, track the progress of incident resolution, and automate workflows to remediate the incidents instantly, all from a single console.
- Secure confidentiality and integrity of sensitive data: Protect databases and files/folders that store business-critical data from intruders. Put them on radar and get to know immediately when there's an unauthorized access attempt or manipulation of data, privilege escalations and more.
- Detect suspicious user behaviors and advanced persistent threats (APTs): With the machine-learning driven user and entity behavior analytics component, automatically baseline normal user behavior and spot user and entity anomalies in real-time. Couple the anomalies with risk scoring to detect slow attacks and APTs.
- Secure cloud platform: Conduct security auditing and understand the security posture of IaaS, PaaS, and SaaS platforms such as AWS, Azure, Google Cloud, Salesforce, etc., Get insights on the security events happening on these platform with intuitive graphical dashboards and analytical reports.
- Comply with regulatory mandates at ease: Get security audit-ready reports for regulatory mandates such as PCI DSS, FISMA, HIPAA, SOX, GDPR, and more.
