The study “A Systematic Comparison of Default-based Versus Hardened IoT Systems Using Honeypots” explores the security differences between default and hardened IoT configurations using honeypots. Researchers deployed IoT devices with both default and hardened settings, monitoring attack patterns and vulnerabilities through platforms like Shodan, Zabbix, and TPOT.
You Should Know:
1. Honeypot Deployment
Deploying IoT honeypots helps analyze attacker behavior. Common tools include:
– Cowrie (SSH honeypot):
docker run -p 2222:2222 cowrie/cowrie
– T-Pot (Multi-honeypot platform):
git clone https://github.com/telekom-security/tpotce cd tpotce/iso/installer/ ./install.sh --type=auto
2. Shodan for IoT Exposure Checks
Use Shodan to identify exposed IoT devices:
shodan search "default password" port:22 shodan host <IP>
3. Hardening IoT Devices
Key steps to secure IoT systems:
- Disable default credentials:
passwd Change default passwords
- Disable unused services:
systemctl stop sshd If SSH is unnecessary systemctl disable sshd
- Enable firewall rules (UFW):
sudo ufw enable sudo ufw allow 80/tcp Only allow necessary ports
4. Monitoring with Zabbix
Deploy Zabbix for real-time IoT security monitoring:
sudo apt install zabbix-server-mysql zabbix-frontend-php sudo systemctl enable zabbix-server
5. Detecting SSH Bruteforce Attacks
Check failed SSH attempts:
grep "Failed password" /var/log/auth.log
Block repeated attackers with `fail2ban`:
sudo apt install fail2ban sudo systemctl start fail2ban
What Undercode Say
Hardening IoT devices significantly reduces attack surfaces. Default configurations remain prime targets for botnets like Mirai. Using honeypots provides actionable threat intelligence, while tools like Shodan expose vulnerable systems. Continuous monitoring with Zabbix and automated defenses like fail2ban enhance IoT security.
Expected Output:
- Honeypot logs revealing attack patterns
- Shodan queries identifying exposed devices
- Hardened IoT configurations resisting common exploits
- Automated alerts from Zabbix on suspicious activity
