DFIR vs SOC Analysis: Which Blue Team Path Should You Learn First?

If you’re getting into defensive cyber security, you’ll likely come across two areas: SOC analysis and digital forensics and incident response (DFIR). 

Both involve investigating threats, analysing evidence, and helping organisations handle security incidents. But they approach that work from different starting points.

• SOC analysis is usually a good place to begin if you’re learning how to investigate alerts, recognise suspicious activity, and decide when to escalate.
• DFIR takes those investigative skills further, with a stronger focus on reconstructing incidents, examining compromised systems, and understanding the full extent of an attack.

This guide compares both paths, explains the skills you’ll develop, and helps you decide where to start with TryHackMe. 

DFIR vs SOC Analysis: What’s the Difference?

The main difference comes down to the work you’re investigating and how deeply you need to examine the evidence. 

What Is SOC Analysis?

SOC analysis is the security monitoring and investigation work carried out within a security operations centre (SOC).

SOC analysts review alerts from security tools, investigate suspicious activity, and determine whether something requires further action.

For example, an analyst might receive an alert about unusual activity on a Windows workstation. 

They would review the process, investigate related events, check whether the activity is legitimate, and decide whether to close or escalate the case. 

The work typically involves:

• Monitoring alerts and identifying potential threats.
• Investigating logs, endpoint activity, and network events.
• Separating legitimate activity from suspicious behaviour.
• Documenting findings and escalating incidents when necessary.

Depending on their role and experience, SOC analysts may also help contain threats or investigate incidents in greater depth.

What Is DFIR?

Digital forensics and incident response (DFIR) combines investigating digital evidence with the work needed to contain threats, remove attacker access, and restore affected systems.

Digital forensics focuses on examining evidence to understand what happened. Incident response uses those findings to guide the organisation's actions.

For example, after a compromised account is discovered, a DFIR practitioner might investigate how the attacker gained access, which systems they reached, what they changed, and whether they left behind persistence mechanisms.

The work can involve:

• Collecting and preserving evidence from affected systems.
• Analysing Windows artefacts, memory, logs, and file system activity.
• Reconstructing attack timelines and identifying compromised assets.
• Supporting containment, eradication, and recovery.

DFIR covers many environments, including cloud, mobile, and enterprise networks. This article focuses primarily on Windows investigations because they are central to TryHackMe’s Windows Incident Response & Forensics path. 

SOC Analysis vs DFIR: Side-by-Side Comparison

The responsibilities often overlap. A SOC analyst may investigate an incident from start to finish, while a DFIR practitioner may use the same SIEM and endpoint tools.

The distinction helps you decide which skills to develop first. 

How Would a SOC Analyst and DFIR Practitioner Investigate the Same Incident?

Imagine an employee account connects to a company file server through Remote Desktop Protocol (RDP) late at night.

An endpoint security tool also detects suspicious activity on the server, and the account owner cannot immediately confirm whether the connection was expected.

Here's how the investigation might unfold.

The SOC Analyst: Investigating the Initial Alert

The SOC analyst starts by determining whether the activity represents a threat.

They might:

1. Review the alert, affected server, account, and source IP address.
2. Examine authentication records to understand when and where the session started.
3. Check related endpoint activity for suspicious processes or commands.
4. Look for similar activity involving other systems or accounts.
5. Document the findings and escalate if the evidence suggests compromise.

At this stage, the analyst may identify suspicious account activity without knowing exactly how the attacker gained access.

Their investigation provides the evidence and context needed for further action. 

The DFIR Practitioner: Reconstructing the Incident

The DFIR investigation examines what happened before, during, and after the suspicious session.

A practitioner might collect evidence from the relevant Windows systems and investigate:

• Initial access: How was the account compromised?
• Execution: What commands or programs ran during the session?
• Persistence: Did the attacker create a scheduled task, service, or another way to regain access?
• Lateral movement: Were additional systems accessed?
• Impact: What data or systems were affected?

The findings are brought together into an incident timeline that helps establish the scope of the compromise.

That evidence can guide decisions about isolating systems, resetting credentials, removing attacker access, and restoring services.

Both investigations contribute to the same response. The SOC work identifies and develops the suspicious activity, while DFIR places greater emphasis on reconstructing the intrusion and establishing its full impact.

Which Blue Team Path Should You Learn First?

Your starting point depends on how comfortable you already are with security fundamentals and the type of investigation you want to perform.

Start With SOC Level 1 If You're Building Your Foundations

TryHackMe's SOC Level 1 path is a practical starting point for beginners who want to understand defensive security.

It introduces the tools, techniques, and investigative thinking used in a SOC.

You'll develop skills such as:

• Reading and interpreting security alerts.
• Investigating logs and related events.
• Recognising common attacks.
• Using security monitoring tools.
• Reporting findings and escalating incidents.

These foundations remain useful if you later specialise in digital forensics or incident response.

If Windows, networking, or command-line basics are still unfamiliar, work through Cyber Security 101 before moving into more demanding investigations.

Choose Windows Incident Response & Forensics for Deeper Investigations

TryHackMe's Windows Incident Response & Forensics path focuses on investigating Windows intrusions and understanding the evidence attackers leave behind.

You'll explore collection techniques and Windows artefacts while investigating activities such as credential access, persistence, and lateral movement.

The path also develops your ability to reconstruct timelines and use forensic findings to support incident response.

The Introduction to Windows IR room expects familiarity with Windows and incident response fundamentals. SOC Level 2 is recommended preparation, although completing it is optional.

You can begin with equivalent knowledge gained through other training or hands-on experience.

Where Does SOC Level 2 Fit?

SOC Level 2 is useful when you want to develop more advanced investigation skills across different security environments.

It covers areas such as advanced SIEM investigations, Active Directory, cloud security, detection engineering, threat hunting, and malware analysis.

Choose SOC Level 2 if you're interested in improving your broader SOC investigation and detection capabilities.

Windows Incident Response & Forensics may be more suitable if you want to concentrate on collecting host evidence and reconstructing Windows attacks.

You can study both over time. The knowledge gained in one often makes the other easier to understand.

Try These Hands-On Exercises Before Choosing

If you're still unsure, try a short practical exercise from each area.

You don't need to master the tools or solve every challenge. Pay attention to the work you enjoy and the questions you want to investigate further.

Exercise 1: Practise SOC Alert Investigation

Start with TryHackMe's SOC L1 Alert Triage and SOC L1 Alert Reporting rooms.

As you work through the exercises, document:

• What triggered the alert and which systems or accounts were involved.
• Which evidence you examined and what it revealed.
• Whether the activity was suspicious and why.
• What you would recommend doing next.

You should finish with a short investigation report that another analyst could follow.

Exercise 2: Practise Windows Forensic Investigation

Try the Key Artefacts for DFIR room to understand the evidence available on Windows systems.

Then explore RDP Lateral Movement Analysis.

Use the available evidence to build a short timeline showing:

• Which accounts and hosts were involved.
• When the suspicious activity occurred.
• What actions you can confirm from the evidence.
• Which questions remain unanswered.

This introduces the process of reconstructing activity and understanding how different artefacts connect.

If you enjoy investigating what happened across a system and building a detailed account of an intrusion, DFIR may be worth exploring further.

Keep all practice within authorised lab environments and follow the rules for sharing room solutions or evidence.

How to Build Your Blue Team Skills Over Time

You can use both paths as part of a broader learning plan.

A simple progression looks like this:

As you progress, keep examples of your investigations.

A short alert report and an incident timeline can show how your skills are developing. Record the evidence you used, the reasoning behind your conclusions, and anything you would investigate differently next time.

These examples can also become part of a cyber security portfolio, provided you respect the training environment's publishing rules.

Start With the Blue Team Skills You Want to Build

Both SOC analysis and DFIR can lead to rewarding work in defensive security. The right starting point is the one that helps you build confidence with the investigations you want to handle.

If you're new to blue teaming, SOC Level 1 gives you a practical foundation in alert triage, security monitoring, and investigation.

If you're ready to examine Windows compromises in more depth, Windows Incident Response & Forensics helps you develop the skills to collect evidence, reconstruct attacks, and support incident response.
