Learn SOC Analyst Responsibilities by Simulating Incident Detection and Response

You are a Junior SOC Analyst at CyberSecure Solutions. The monitoring system has generated an alert indicating suspicious activity on an employee's workstation.

Your task is to investigate the alert, determine whether it is a security incident, take an appropriate response action, and document the incident.

Understand how a SOC analyst analyzes an incoming alert.

2) Roles and responsibilities of a SOC analyst

3) Security monitoring fundamentals

Steps

1. Open the SIEM dashboard.

2. Navigate to the Alerts/Security Events section.

3. Select the assigned alert.

4. Record:

   • Alert name

   • Date and time

   • Source IP

   • Destination/target

   • Username

   • Event type

   • Severity

5. Determine whether the alert appears suspicious.

Steps

1. Open the SIEM dashboard.

2. Navigate to the Alerts/Security Events section.

3. Select the assigned alert.

4. Record:

   • Alert name

   • Date and time

   • Source IP

   • Destination/target

   • Username

   • Event type

   • Severity

5. Determine whether the alert appears suspicious.

Example

Multiple Failed Logins

        ↓

Identify User

        ↓

Check Source IP

        ↓

Check Timestamp

        ↓

Analyze Activity

Expected Output

Students identify the important information contained in a security alert.

Determine whether the alert represents a real security incident.

Steps

1. Review related logs around the alert time.

2. Check whether multiple failed attempts occurred.

3. Check the affected user/account.

4. Check the source IP.

5. Look for other suspicious events.

6. Determine the incident status:

Benign / False Positive

        OR

Potential Security Incident

7. Record your conclusion.

Expected Output

Students provide a short investigation summary supported by log evidence.

Understand how SOC analysts prioritize incidents.

Steps

1. Identify the type of incident.

2. Determine its severity.

3. Consider:

   • Number of affected systems

   • Type of activity

   • User/account involved

   • Potential business impact

4. Assign a severity:

Low

Medium

High
Critical

Expected Output

Apply an appropriate defensive action.

Steps

• Disable a test account.

• Reset a test user's password.

• Isolate a test endpoint.

• Block a test IP address.

• Remove unauthorized access.

Then:

1. Confirm the action was successful.

2. Monitor the SIEM for additional events.

3. Determine whether the suspicious activity has stopped.

Expected Output

Students demonstrate a basic incident containment and response process.

Create a basic SOC incident report.

Example Incident Summary

Incident: Multiple Failed Login Attempts

Detection:

SIEM generated an alert for repeated failed logins.

Investigation:

The analyst reviewed the username, source IP,

timestamp and related events.

Response:

The affected test account was disabled.

Status:

Incident contained and resolved.

Expected Outcome

After completing this lab, students will be able to:

• Explain the role of a SOC analyst.

• Analyze security alerts.

• Investigate logs and suspicious activity.

• Classify incidents based on severity.

• Perform basic incident containment.

• Document and close incidents.

• Investigate logs and suspicious activity.

• Classify incidents based on severity.

• Perform basic incident containment.

• Document and close incidents.

Student Deliverables

Students should submit:

• Alert Analysis

• Investigation Notes

• Incident Classification

• Response Action

• Incident Report
