You Should Know:
1. Detection Engineering and Security Operations (SOC)
Detection engineering represents the evolution of traditional security operations from reactive monitoring to proactive threat hunting and automated response. This discipline focuses on developing, testing, and refining detection rules that identify malicious activity across enterprise environments while minimizing false positives.
Extended Technical Overview:
Modern SOC teams leverage SIEM platforms, EDR solutions, and custom detection frameworks to identify threats in real-time. The shift from signature-based detection to behavioral analytics and machine learning has transformed how security teams approach threat identification.
Linux Commands for Log Analysis:
Monitor system logs in real-time with filtering
sudo tail -f /var/log/syslog | grep -i "failed|error|unauthorized"
Parse Apache access logs for suspicious patterns
cat /var/log/apache2/access.log | awk '{print $1}' | sort | uniq -c | sort -1r
Search for privilege escalation attempts in auth logs
sudo grep "sudo" /var/log/auth.log | grep -i "FAILED"
Extract IP addresses from firewall logs
sudo cat /var/log/ufw.log | grep -oE 'SRC=[0-9.]+' | cut -d= -f2 | sort | uniq -c
Windows PowerShell Commands for Security Monitoring:
Query Windows Event Log for failed logins (Event ID 4625)
Get-WinEvent -LogName Security | Where-Object { $_.Id -eq 4625 } | Select-Object TimeCreated, Message -First 20
Monitor PowerShell script block logging (Event ID 4104)
Get-WinEvent -LogName "Microsoft-Windows-PowerShell/Operational" | Where-Object { $_.Id -eq 4104 }
Extract network connections and associated processes
Get-1etTCPConnection | Select-Object LocalAddress, LocalPort, RemoteAddress, RemotePort, State, OwningProcess
Check for suspicious scheduled tasks
Get-ScheduledTask | Where-Object { $_.State -1e "Disabled" } | Select-Object TaskName, TaskPath, State
Step-by-Step Guide: Building a Basic Detection Rule
- Define the threat scenario: Identify the specific adversary behavior to detect
- Collect relevant telemetry: Ensure log sources provide necessary data
- Develop the detection logic: Create query that identifies suspicious activity
- Test with simulated attacks: Verify detection fires appropriately
- Tune thresholds: Reduce false positives while maintaining detection accuracy
- Deploy to production: Implement rule in SIEM or detection platform
- Monitor performance: Track detection rate and false positive ratio
Sigma Rule Example (YAML format):

2. Cloud Security Architecture
Cloud security architecture requires a deep understanding of cloud service provider infrastructures, identity management, network security, and compliance frameworks. Professionals must design secure cloud environments from the ground up, implementing controls that protect data across IaaS, PaaS, and SaaS models.
Extended Technical Overview:
The shared responsibility model creates unique security challenges where organizations must protect their configurations, data, and access controls while relying on providers for physical security and infrastructure protection. Misconfigurations remain the leading cause of cloud security breaches.

Zero Trust security operates on the principle of “never trust, always verify,” requiring continuous authentication and authorization for every access request, regardless of network location. Identity management becomes the new security perimeter.
Extended Technical Overview:
Zero Trust architectures eliminate implicit trust based on network location, requiring strong authentication, device health verification, and least-privilege access for all users and services. Identity and access management (IAM) forms the foundation of this model.
Linux Commands for Identity Management:

5. AI Security and Cyber Resilience
AI security encompasses protection of AI/ML systems, securing data pipelines, maintaining model integrity, and using AI for threat detection. Cyber resilience ensures organizations maintain business functions during and after cyberattacks.
Extended Technical Overview:
The proliferation of AI in cybersecurity creates both opportunities and risks. Adversaries increasingly target AI models with data poisoning, model evasion, and adversarial attacks, while defenders leverage machine learning to detect sophisticated threats that traditional systems miss.

X = training_data[bash]
y = training_data['is_malicious']
model = RandomForestClassifier(n_estimators=100, random_state=42)
model.fit(X, y)
joblib.dump(model, 'anomaly_detector.pkl')
return model
def detect_anomalies(new_data):
model = joblib.load('anomaly_detector.pkl')
predictions = model.predict(new_data)
probabilities = model.predict_proba(new_data)
anomalies = new_data[probabilities[:,0] < 0.3]
return anomalies if not anomalies.empty else None
Check for adversarial example detection
def detect_adversarial(input_data, threshold=0.3):
