Phòng thủ An ninh mạng

Cybersecurity Defense là game tower-defense-style learning experience where you protect enterprise networks từ realistic cyber attacks: phishing emails, ransomware, DDoS floods, SQL injections, zero-day exploits, insider threats, và APT (Advanced Persistent Threats) - same attacks companies face daily! Game đặt bạn vai Security Operations Center (SOC) analyst monitoring real-time logs, identifying suspicious activities, deploying countermeasures (firewalls, IDS/IPS, EDR agents, SIEM rules), và responding to breaches. Progressive waves: (1) Basic attacks (port scans, brute force logins) → detect patterns, block IPs, (2) Social engineering (phishing campaigns) → train employees, email filters, (3) Malware infections (ransomware, trojans) → quarantine, forensics, recovery, (4) Advanced attacks (supply chain compromise, living-off-the-land techniques).

Game teach defense-in-depth strategy: (1) Perimeter security (firewalls, VPN), (2) Network segmentation (isolate critical systems), (3) Endpoint protection (antivirus, EDR), (4) Access controls (least privilege, MFA), (5) Monitoring/logging (SIEM analytics), (6) Incident response (contain, eradicate, recover), (7) User training (human firewall!). Real tools simulated: Wireshark packet analysis, Splunk log searching, Nessus vulnerability scanning, Metasploit (ethical hacking testing defenses), MITRE ATT&CK framework mapping. Scenarios based actual breaches: (1) Colonial Pipeline ransomware, (2) SolarWinds supply chain attack, (3) Target POS breach, (4) Equifax data leak - learn from history!

Game có "red team vs blue team" mode: attack opponents defenses, learn attacker mindset to defend better. Economics layer: balance security budget, calculate risk vs cost, justify investments to executives. Compliance requirements: GDPR, HIPAA, PCI-DSS - understand regulatory drivers.

Phù hợp college cybersecurity programs, IT professionals upskilling, aspiring SOC analysts, và anyone protecting personal/business assets online. Game preparation cho certifications: Security+, CEH, CISSP!
