🌐 Phase 1: Networking Fundamentals

> Timeline: Weeks 1-4 · Effort: 2-3 hours/day

Every security alert in network traffic. You cannot in threats, write detection rules, or analyze incidents without understanding how data mo networks.

What to Learn

#### 1.1 OSI Model & TCP/IP Stack

The 7-layer OSI model and how it maps to the 4-layer TCP/IP model

What happens at each layer (Physical, Data Link, Network, Transport, Session, Presentation, Application)

How encapsulation works (data → segment → packet → frame → bits)

Why this matters for security: understanding which layer an attack targets helps you choose the right detection method

IPv4 address structure (32-bit, dotted decimal notation)

Private IP ranges (10.x.x.x, 172.16-31.x.x, 192.168.x.x)

CIDR notation (/24, /16, /8 and what they mean)

Subnet masks and how to calculate network/host portions

NAT (Network Address Translation) and why it exists

IPv6 basics (128-bit, hexadecimal notation)

#### 1.3 Critical Protocols & Ports
You need to memorize these. They appear in every SOC in:

| Kerberos | 88 | Authentication | Kerberoasting, Golden Ticket |
| Syslog | 514 | Log forwarding | Log analysis, SIEM ingestion |
| SNMP | 161/162 | Network management | Information disclosure |

#### 1.4 Network Devices & Architecture

Routers: Forward traffic between networks, operate at Layer 3

Switches: Forward traffic within networks, operate at Layer 2

Firewalls: Filter traffic based on rules (stateful )

Proxies: Intermediate between clients and servers (forward )

Load Balancers: Distribute traffic across servers

IDS/IPS: Detect (IDS) or prevent (IPS) malicious traffic

VLANs: Logically segment networks

<a id="phase-2-windows-essentials"></a>

🖥️ Phase 2: Windows Essentials

> Timeline: Weeks 3-6 · Effort: 2-3 hours/day

Over 90% of enterprise en run Windows with Acti. As a SOC analyst, Windows Event Logs will be your primary data source. Understanding how Windows works internally is not optional, it is the foundation of your daily work.

What to Learn

#### 2.1 Acti (AD)

Domains, forests, and trusts: hierarchical structure of AD

Users, groups, and OUs: how access is organized

Group Policy Objects (GPO): how administrators enforce settings across machines

Kerberos authentication: TGT, TGS, service tickets, and why attackers love it

NTLM authentication: legacy protocol, pass-the-hash attacks

Domain Controllers: the most critical servers in any enterprise

#### 2.2 Windows Event Logs (Critical Skill)
This is the #1 skill for SOC analysts. You must be able to read, filter, and correlate Windows events.

Event IDs You Must Memorize:

| Event ID | Log | What It Means | Why It Matters |
|----------|-----|--------------|----------------|
| 4624 | Security | Successful logon | Track who accessed what |
| 4625 | Security | Failed logon | Brute force detection (multiple = attack) |
| 4634 | Security | Logoff | Session tracking |
| 4648 | Security | Explicit credential logon | Lateral mo indicator |
| 4672 | Security | Special pri assigned | Admin access granted |
| 4688 | Security | New process created | Malware execution detection |
| 4689 | Security | Process exited | Process lifecycle tracking |
| 4720 | Security | User account created | Persistence technique |
| 4724 | Security | Password reset attempt | Pri escalation |
| 4728 | Security | Member added to security group | Pri escalation |
| 4732 | Security | Member added to local group | Local admin escalation |
| 1102 | Security | Audit log cleared | Almost always malicious |
| 7045 | System | New service installed | Malware persistence |
| 4104 | PowerShell | Script block logging | Malicious PowerShell detection |
| 1 | Sysmon | Process creation | Detailed process tracking |
| 3 | Sysmon | Network connection | C2 communication detection |
| 11 | Sysmon | File creation | Dropped files, malware delivery |
| 22 | Sysmon | DNS query | DNS-based C2, DGA detection |

How to read Event Log sequences (attack stories):

Multiple 4625 → single 4624 = successful brute force

4720 + 4728 (Domain Admins) = account creation + pri escalation

4688 with suspicious process names (powershell.exe, cmd.exe, certutil.exe) = potential malware execution

1102 = someone cleared logs to co

#### 2.3 PowerShell for In
Essential commands every SOC analyst uses:

#### 2.4 Sysmon
Sysmon is a Windows system service that provides detailed telemetry on process creation, network connections, file creation, and more. It is essential for any SOC.

Install with SwiftOnSecurity's Sysmon config for a well-tuned baseline

Alternative: Olaf Hartong's Sysmon Modular config

Learn the key Sysmon Event IDs (1, 3, 7, 8, 10, 11, 13, 22)

#### 2.5 Windows Registry & Services

Registry run keys (HKLM\SOFTWARE\Microsoft\Windows\Current\Run), common persistence location

Services (services.msc), malware often installs as a service

Scheduled Tasks, another persistence mechanism

WMI subscriptions, ad persistence technique

Authorization (AuthZ): What you're allowed to do (RBAC, ACLs)

Accounting: Logging what you did (audit trails, SIEM)

Non-repudiation: Cannot deny an action (digital signatures)

Least Pri: Minimum access needed for each role

Defense in Depth: Multiple layers of security controls

Zero Trust: Ne, always , regardless of network location

#### 5.2 Common Attack Types

Every SOC analyst must understand these attack categories:

| Attack | How It Works | Detection Method |
|--------|-------------|-----------------|
| Phishing | Fraudulent emails trick users into clicking links or downloading files | Email gateway logs, user reports, header analysis |
| Brute Force | Automated password guessing | Multiple 4625 events, account lockouts |
| Credential Stuffing | Using leaked credentials from other breaches | Multiple 4625 from many accounts, single source |
| Malware | Malicious software (virus, trojan, worm, RAT) | EDR alerts, unusual process behavior, network anomalies |
| Ransomware | Encrypts files, demands payment | Mass file modifications, suspicious process execution |
| SQL Injection | Injecting SQL commands into web forms | WAF alerts, unusual database queries |
| Cross-Site Scripting (XSS) | Injecting scripts into web pages | WAF alerts, unusual Ja in requests |
| Man-in-the-Middle | Intercepting communications | Certificate warnings, ARP anomalies |

10.4 Interview Preparation

SOC analyst interviews typically ha parts: beha/cultural fit, foundational concepts, and scenario-based in. Scenario questions carry the most weight because they reveal how you actually think and work under pressure. Lab and CTF experiences absolutely count as real experience.

#### Foundational Concept Questions

These test whether you understand the basics. Expect them early in the interview.

| Question | What They're Testing |
|----------|---------------------|
| "Explain the CIA Triad with examples" | Can you connect theory to real-world security |
| "What is the difference between IDS and IPS?" | IDS monitors and alerts, IPS monitors and blocks |
| "Describe the TCP three-way handshake" | SYN, SYN-ACK, ACK and why it matters for detection |
| "What is the difference between encryption and hashing?" | Encryption is re (AES, RSA), hashing is one-way (SHA256, MD5) |
| "Explain authentication " | AuthN = who you are, AuthZ = what you can access |
| "What is the difference between a , a threat, and a risk?" | Weakness danger x impact |
| "What does the Zero Trust model mean?" | Ne, always , regardless of network location |
| "Name 5 common ports and their services" | Tests memorization: 22/SSH, 53/DNS, 80/HTTP, 443/HTTPS, 3389/RDP |
| "What is DNS and how does resolution work?" | Recursi, root servers, TLD, authoritati |
| "What is the difference between TCP and UDP?" | Connection-oriented , reliability |
| "Explain what a VLAN is and why it matters for security" | Logical network segmentation, reduces attack surface |
| "What is NAT and why is it used?" | Translates private IPs to public, hides internal network structure |

#### Framework & Methodology Questions

These test your understanding of how security operations are structured.

| Question | What They're Testing |
|----------|---------------------|
| "Walk me through the NIST Incident Response phases" | Preparation, Detection & Analysis, Containment/Eradication/Recovery, Post-Incident |
| "How do you use MITRE ATT&CK in your daily work?" | Map alerts to techniques, identify detection gaps, guide threat hunting |
| "What is the Cyber Kill Chain and how would you use it?" | Understanding attack progression, detecting at each stage |
| "Explain the difference between NIST CSF and CIS Controls" | CSF = strategic framework (5 functions), CIS = tactical controls (18 prioritized actions) |
| "What is the difference between a true positi positive, true negative, and false negative?" | Critical for alert triage: TP = real alert, FP = false alarm, FN = missed attack (most dangerous) |
| "How would you reduce false positives in a SIEM?" | Tune rules, add context/whitelists, correlate with threat intel, adjust thresholds |
| "What are IOCs and how do you use them?" | Indicators of Compromise: IPs, domains, hashes, file names used to detect known threats |
| "What is the difference between IOCs and TTPs?" | IOCs are specific artifacts (change often), TTPs are beha patterns (harder to change) |

#### Tools & Technical Questions

These test your hands-on skills with the tools you will use daily.

| Question | What They're Testing |
|----------|---------------------|
| "Have you used any SIEM tools? Write a basic query" | Practical Splunk SPL or KQL ability |
| "What is Sysmon and which Event IDs are most useful?" | Event ID 1 (process creation), 3 (network), 11 (file create), 22 (DNS) |
| "Explain what SIGMA rules are and why they matter" | detection rules, con to any SIEM query format |
| "What Windows Event ID indicates a successful logon? A failed one?" | 4624 = success, 4625 = failed |
| "How would you detect someone clearing Windows Event Logs?" | Event ID 1102 in Security log |
| "What tools would you use for memory forensics?" | (standard), also Rekall |
| "What is the purpose of Wireshark display filters filters?" | Display filters = filter what you see, capture filters = filter what is collected |
| "You see Event ID 7045 in a Windows system log. What does it mean?" | New service installed, potential persistence mechanism |
| "What is the difference between EDR and antivirus?" | A file scanning, EDR = beha monitoring, detection, and response |
| "How does Kerberos authentication work?" | TGT from KDC, TGS for services, why attackers target it (Kerberoasting, Golden Ticket) |

#### Scenario-Based Questions (Most Important)

These carry the most weight. Inter want to see your thought process, not a perfect answer.

Scenario 1: Phishing In
> "A user reports a suspicious email. Walk me through your in."

Scenario 2: Brute Force Detection
> "You see 500 failed login attempts from a single IP in 10 minutes followed by a successful login. What do you do?"

Scenario 3: Suspicious Process Execution
> "Your EDR alerts on powershell.exe spawning from winword.exe. What does this mean and what do you do?"

Scenario 4: Lateral Mo Detection
> "You notice a service account authenticating to 15 different servers within 3 minutes. Is this normal?"

Scenario 5: Ransomware Response
> "Multiple users report they cannot open their files and see a ransom note on their desktops. What are your first steps?"

Scenario 6: Insider Threat
> "DLP alerts show a user downloading 2GB of customer data to a USB drive at 11 PM. How do you handle this?"

Scenario 7: SIEM Down During an Incident
> "Your SIEM goes down while you're in an acti. What do you do?"

#### Beha Questions

Don't underestimate these. They assess culture fit and how you handle real-world SOC pressures.

| Question | What They Want to Hear |
|----------|----------------------|
| "How do you stay current with cybersecurity news?" | Specific sources: DFIR Report, Krebs, Darknet Diaries, Twitter/X infosec community, RSS feeds |
| "Describe a time you had to learn something quickly" | Show adaptability, mention a specific tool or concept from labs/CTFs |
| "How do you handle working rotating shifts?" | Honest answer about work-life balance, show you understand SOC reality |
| "What do you do when you disagree with a senior analyst's assessment?" | Respectful pushback with e, escalation path, willingness to learn |
| "How do you prioritize when multiple alerts fire at once?" | Se triage, critical assets first, follow the playbook, communicate with team |
| "Tell me about a mistake you made and what you learned" | Shows self-awareness, growth mindset, process impro |
| "Why Blue Team instead of Red Team?" | Genuine answer about defending, protecting people, the challenge of detection |
| "What's a recent security breach you found interesting?" | Demonstrates you follow the industry, can analyze from a defender's perspective |
