Introduction

In modern Security Operations Centers (SOCs), two critical roles—Cybersecurity Analysts and Incident Responders—work in tandem to detect, analyze, and mitigate threats. While both roles are essential, their responsibilities, tools, and objectives differ significantly. This article breaks down their functions, key tools, and practical commands used in real-world scenarios.

Learning Objectives

  • Understand the core responsibilities of a Cybersecurity Analyst vs. an Incident Responder.
  • Learn essential SIEM queries, forensic commands, and malware analysis techniques.
  • Discover key tools used in threat detection and incident response.

You Should Know

1. SIEM Log Analysis for Threat Detection

Command (Splunk Query for Suspicious Logins):

index=security sourcetype=win_eventlogs EventCode=4625 
| stats count by src_ip, user 
| where count > 5 
| table src_ip, user, count

What This Does:

  • Searches for failed login attempts (Event ID 4625) in Windows logs.
  • Aggregates by source IP and username, flagging brute-force attacks.

Step-by-Step:

1. Log into Splunk/QRadar.

  1. Run the query to detect multiple failed logins.
  2. Investigate IPs with high failure rates for potential breaches.

2. Endpoint Detection & Response (EDR) Commands

Command (CrowdStrike Falcon Query for Malicious Processes):

cscli process list --filter "status:malicious" --fields name,pid,parent_name,cmdline

What This Does:

  • Lists malicious processes detected by CrowdStrike.
  • Shows process name, PID, parent process, and command line for forensic analysis.

Step-by-Step:

1. Connect to CrowdStrike Falcon console.

2. Run the command to identify suspicious processes.

3. Terminate malicious processes using `kill -9 

`.</h2>

<h2 style="color: yellow;"> 3. Memory Forensics with Volatility</h2>

<h2 style="color: yellow;">Command (Dumping Suspicious Processes from Memory):</h2>

[bash]
volatility -f memory.dump pslist | grep -i "explorer|powershell"

What This Does:

  • Extracts running processes from a memory dump.
  • Flags hidden malware masquerading as explorer.exe or PowerShell.

Step-by-Step:

  1. Acquire memory dump using `dumpit` or FTK Imager.

2. Run Volatility to analyze processes.

3. Extract malicious payloads for further analysis.

4. Network Traffic Analysis with Wireshark/Tshark

Command (Detecting C2 Traffic):

tshark -r traffic.pcap -Y "dns.qry.name contains 'malicious-domain.com'"

What This Does:

  • Filters DNS queries to known malicious domains in a PCAP file.
  • Helps identify Command & Control (C2) communications.

Step-by-Step:

1. Capture network traffic using Wireshark.

  1. Run the Tshark command to detect C2 traffic.

3. Block malicious domains at the firewall.

5. Malware Sandbox Analysis with ANY.RUN

Command (Submitting Suspicious File for Analysis):

curl -X POST -H "Authorization: Bearer API_KEY" -F "[email protected]" https://api.any.run/v1/analysis

What This Does:

  • Submits a file to ANY.RUN for dynamic analysis.
  • Returns behavioral analysis, network activity, and IOCs.

Step-by-Step:

1. Obtain an API key from ANY.RUN.

  1. Submit the malware sample via API or web interface.

3. Review the report for malicious activity.

6. Incident Response: Killing Malicious Services

Command (Windows – Terminating Malicious Services):

Get-Service | Where-Object {$_.DisplayName -like "suspicious"} | Stop-Service -Force

What This Does:

  • Identifies and stops malicious services running on Windows.

Step-by-Step:

1. Open PowerShell as Administrator.

2. Run the command to stop suspicious services.

3. Delete persistence entries from the Registry.

7. Post-Incident: Patching Vulnerabilities

Command (Nessus Vulnerability Scan via CLI):

nessuscli scan --target 192.168.1.0/24 --policy "Critical Vulnerabilities"

What This Does:

  • Scans a subnet for critical vulnerabilities.
  • Generates a report for patching prioritization.

Step-by-Step:

1. Install Nessus and configure scan policies.

2. Run the scan against target networks.

3. Apply patches based on findings.

What Undercode Say

  • Key Takeaway 1: Cybersecurity Analysts focus on proactive threat detection, while Incident Responders handle reactive containment and forensics.
  • Key Takeaway 2: Mastery of SIEM queries, EDR tools, and forensic analysis is critical for both roles.

Analysis:

The evolving threat landscape demands specialized skills in both detection and response. SOC teams must integrate AI-driven analytics (like UEBA) and automated SOAR playbooks to stay ahead. Future attacks will leverage AI-generated malware, requiring analysts and responders to adopt behavioral analysis over signature-based detection.

Prediction

By 2026, AI-powered SOCs will dominate, reducing manual triage by 40%. However, human expertise in interpreting AI findings and handling complex incidents will remain irreplaceable. Organizations must invest in continuous training (like Ethical Hackers Academy’s courses) to bridge the skills gap.
