Based on global data sources’ threat intelligence, it further enhances the ability to detect attacks using known techniques and emerging threats.

➤ User and Entity Behavioral Analytics (UEBA)

Azure Advanced Threat Protection uses UEBA to monitor how users and devices behave constantly within the network. It looks for deviations from established patterns, changes in logins to other locations, and unusual access to files. What those anomalies indicate helps identify threats and point out compromised user accounts and insider attacks.

➤ Advanced Incident Investigation

It supports real-time monitoring activity in and out of the premises and cloud environments to ensure steady visibility into network activities. It enables fast threat detection and response, reducing the risk of damage. Azure Advanced Threat Protection offers a way to investigate incidents deeply. It informs the user of the detected threat and provides the sequence of events to show how the attack went down. It helps security teams grasp the full extent and impact of the incident.

➤ Real-time Monitoring

It supports real-time monitoring, whether on-premises or cloud, and provides continuous network activity visibility. It ensures speedy detection and response to threats and damage mitigation.

How Azure Advanced Threat Protection Works

Here’s how Advanced Threat Protection in Azure works:

➤ Deployment and Configuration

Azure Advanced Threat Protection deploys by setting up sensors on domain controllers or as standalone deployments. These sensors collect data from various sources, including event logs and network traffic. The configuration process involves fine-tuning the sensitivity of detection rules to align with the organization’s environment and security policies.

➤ Data Collection

Advanced Threat Protection in Azure collects essential data, such as Active Directory logs, network traffic, and login activities. This information helps it understand normal behavior and spot unusual or suspicious activity.

➤ Threat Detection and Alerting Mechanism

After collecting the data, the service analyzes it using behavioral analysis, machine learning, and threat intelligence to identify possible threats. Upon detecting a threat, an alert is triggered, which details what kind of threat it is, which users are involved, and how severe the incident is. It allows security teams to review and respond to the incident more quickly.

Identifying and Mitigating Insider Threats with Azure ATP

Most people believe that cyber threats come from outside an organization, but not so. Another critical threat can also come from inside the organization, created by the employee, contractor, or even a partner who accesses the company’s systems. It can range from accidental data leaking to intentional acts harming the organization.

Microsoft Azure ATP’s real-time monitoring and analysis identify all the unusual activities involving users who may pose some risk. It integrates vulnerability scans and security tests into a single solution to identify accidental mistakes and intentional malicious activity on a network. Therefore, it will alert the security team on time if any possible threat has been identified to prevent the situation from worsening.

Common Use Cases for Microsoft Azure ATP:

Here are some common use cases for your reference

➤ Detecting Pass-the-Ticket Attacks

Azure’s Advanced Threat Protection can detect Pass-the-Ticket attacks, in which an attacker uses a stolen ticket to access network services. By monitoring authentication activities, Azure Advance Threat Protection identifies suspicious logins that indicate ticket theft.

➤ Identifying Lateral Movement Paths

Attackers often look for lateral moves on a network to access critical objectives, and ATP in Azure detects such movements in a pattern or escalation of account accesses.

➤ Monitoring for Privilege Escalation Attempts

ATP in Azure detects attempts at high-privilege acquisition that could mean the attacker is trying to gain administrative rights. It also monitors changes in users’ permissions. The security team is alerted when such permission changes are suspected to be malicious.

➤ Recognizing Unusual User Activity or Account Compromises

By continuously analyzing user activities, ATP in Azure an spot signs of account compromises, such as login attempts from unexpected locations or abnormal access to sensitive data.

➤ Tracking Malicious Insider Activities

Insiders with legitimate access can still pose a threat. Azure Advanced Threat Protection identifies malicious insider activities by detecting deviations from typical user behavior, helping prevent data theft or sabotage.
