Define incident creation logic

Incident creation logic is a crucial element when you prepare for the SC-200 Microsoft Security Operations Analyst exam. This concept refers to the process and methods applied in responding to and managing security threats within a digital infrastructure.

Incident creation logic within the Microsoft suite is built around the Microsoft 365 Defender portal. The portal enables a centralized incident page where the user can gauge the entire breadth of an incident in an organized, systematic approach. This functionality allows security operations teams to quickly evaluate and address threats.

Components of Incident Creation Logic in Microsoft 365

Before you delve into the specificities of incident creation logic, it is essential to understand its components. These are the events, alerts, and incidents.

• Events: These are activities within your network recorded by security tools. They can either be normal or malicious network activities. Events become the data source for alerts.
• Alerts: These are the notifications pointing out potential security risks or vulnerabilities. Alerts are often generated from abnormal or suspicious events.
• Incidents: These are aggregated forms of multiple alerts that share a common cause or similarity. Incidents provide a collective view of alerts related to a specific security issue.

Incident Creation Logic

When a suspicious or potentially harmful event is detected in the Microsoft 365 Defender, an alert is triggered. These alerts directly inform the security operations centre (SOC) team about the likely risk. However, it’s not feasible to manage and respond to each alert individually, so the alerts with shared attributes or similar characteristics are combined or correlated to create an incident. This grouping is performed using incident creation logic.

Incident creation logic includes the following attributes that are considered while forming an incident:

• Alerts that have similar MITRE ATT&CK techniques
• Alerts triggered by the same URL or IP address
• Alerts affecting the same device or user
• Alerts having the same Category
• Alerts that occur within the same timeframe

Creating incidents by grouping related alerts helps the SOC to have an aggregated view of potentially harmful activities in the network. This significantly improves the efficiency and effectiveness of their threat response.

This is the pseudocode of how the process would look like:

pseudo
For Any New Alert:
If (the alert shares MITRE ATT&CK techniques with an existing incident):
Add alert to the incident
ElseIf (the alert shares URL, IP, device, user, or category):
Add alert to the incident
Else If (the same alert happened within a timeframe ):
Create a new incident
Else:
Create a new incident

Conclusion

The incident creation logic concept builds the fundamentals of managing security threats in a network effectively. In the SC-200 Microsoft Security Operations Analyst exam as well, understanding this logic will help you tackle incident management questions better. From an operational perspective, it streamlines the process of dealing with alerts and incidents, thereby enhancing the overall security posture of an organization.

Interview Questions

What is incident creation logic?

Incident creation logic is the process within a security system that determines when a security event is significant enough to warrant creating an incident for further investigation. It is defined by certain rules or conditions in the system.

Why is incident creation logic important?

Incident creation logic is important because it helps to filter out noise from the multitude of security alerts and focuses the attention of the security operations team on the most critical and relevant issues.

How does Microsoft’s incident creation logic work?

Microsoft’s incident creation logic works by analyzing security alerts and events and prioritizing them based on the level of threat they pose. The logic uses a combination of algorithms and pre-defined rules to create incidents and prioritize them.

What’s the role of machine learning in incident creation logic within Microsoft Security Operations?

Machine learning plays a critical role in Microsoft’s incident creation logic. It analyzes patterns and trends in data to identify unusual behaviors or anomalies that could indicate a potential security threat. It also aids in the prioritization of incidents based on the level of threat they pose.

Can incident creation logic in Microsoft Security Operations be customized according to an organization’s needs?

Yes, Microsoft Security Operations allows for customization of incident creation logic, tailoring it to an organization’s unique needs. This can involve adjusting the sensitivity of alerts or defining custom rules that trigger incident creation.

How are incidents prioritized in Microsoft Security Operations?

Incidents in Microsoft Security Operations are prioritized based on the severity of their associated alarms. Higher severity alarms generate high priority incidents, while lower severity alarms generate lower priority incidents.

What types of data does the incident creation logic in Microsoft Security Operations analyze?

Incident creation logic analyzes a variety of data, including alarms, events, suspicious activity signals, anomaly detection outputs, and threat intelligence indicators.

What does correlation factor in incident creation logic refer to?

Correlation in incident creation logic refers to the process of linking or associating different events or alarms that might be part of the same threat or incident. Correlation helps to provide a more cohesive view of the potential security threat.

What is the role of Alert Grouping in Microsoft’s incident creation logic?

Alert grouping is an essential component of Microsoft’s incident creation logic. Multiple related alerts are grouped together to form a coherent incident that provides a fuller picture of an event, aiding in further investigation and mitigation.

How does Microsoft’s incident creation logic help improve response times?

By prioritizing high severity incidents and grouping related alerts together, incident creation logic allows security teams to quickly identify and respond to the most serious threats, reducing response times.

What are false positives in the context of incident creation logic?

False positives are alerts generated by the security system that indicate a threat, but on investigation, are found to be normal or harmless activities. The goal of good incident creation logic is to minimize these false positives.

How can advanced analytics be used to improve incident creation logic?

Advanced analytics can be used to detect patterns and trends over time, which can subsequently enhance an incident creation logic’s ability to accurately identify and prioritize genuine security threats.

What are the main challenges in defining incident creation logic?

Major challenges in defining incident creation logic include accurately defining the criteria that warrant an incident, minimizing false positives while avoiding miss real threats, and constantly updating the logic to cope with evolving threat landscapes.

Can incident creation logic in Microsoft Security Operations Centre automatically initiate responses?

Yes, certain responses to detected incidents can be automated within Microsoft Security Operations Center. This could be as simple as sending a notification email, or more complex like isolating a compromised system.

How does threat intelligence correlate with incident creation logic?

Threat intelligence informs incident creation logic by providing indicators of compromise and tactics, techniques, and procedures (TTPs) that are currently being used by attackers. This enables the logic to be attuned to the latest threats and thus better identify incidents.
