Practical labs include securing Linux servers, configuring Windows security policies, and implementing endpoint security controls. This module helps students prepare secure environments and respond to system-level threats.

4. Malware, Threats & Attack Vectors

In this module, learners explore various types of cyber threats, including malware, ransomware, viruses, worms, Trojans, spyware, botnets, rootkits, and keyloggers. The course covers how malware is developed, delivered, and executed in real-world cyberattacks. Students analyze different attack vectors such as phishing, drive-by downloads, man-in-the-middle attacks, password cracking, SQL injection, and insider threats. With access to safe malware analysis labs, learners inspect suspicious files, identify indicators of compromise (IOCs), and learn defensive techniques to prevent and mitigate malware attacks.

5. Vulnerability Assessment & Penetration Testing Basics

Understanding how vulnerabilities are discovered and exploited is crucial in cybersecurity. This module covers the end-to-end vulnerability assessment process, including reconnaissance, scanning, enumeration, and reporting. Students learn how to identify system weaknesses using tools such as Nmap, OpenVAS, Nessus, Nikto, and Burp Suite. They learn to differentiate between low, medium, high, and critical vulnerabilities and understand how to prioritize remediation. The module also introduces penetration testing concepts, ethical hacking methodologies, exploit techniques, and risk management processes. These foundational skills equip learners for both offensive and defensive security roles.

6. Cryptography & Data Security

Cryptography is a fundamental part of cybersecurity. This module teaches the principles of encryption, hashing, digital certificates, and secure communication. Topics include symmetric and asymmetric encryption, SSL/TLS, PKI infrastructure, certificates, authentication methods, steganography, and key management systems. Students learn how cryptography protects data at rest and in transit and how attackers attempt to break encryption. Labs include encrypting/decrypting messages, configuring SSL certificates, and implementing end-to-end secure data transmission models. By the end, learners understand how to apply cryptographic methods to safeguard sensitive data across digital environments.

7. Web Application Security

Web applications are frequent targets of cybercriminals. This module covers OWASP Top 10 vulnerabilities, including SQL injection, cross-site scripting (XSS), broken authentication, insecure deserialization, and security misconfiguration. Students use tools such as Burp Suite, OWASP ZAP, Postman, and browser developer tools to analyze and exploit vulnerable web applications in a safe lab environment. They learn secure coding practices, input validation methods, API security, session management, HTTPS implementation, and common firewall protections such as WAFs. This module ensures students can identify and secure weaknesses in modern web applications.

8. Network Security & Firewalls

Network security forms the backbone of any cybersecurity strategy. This module covers intrusion detection systems (IDS), intrusion prevention systems (IPS), Next-Gen Firewalls (NGFWs), and security devices like routers, switches, proxies, and VPNs. Students learn network segmentation, zero-trust architecture, secure network design, and wireless security protocols. Hands-on activities include configuring firewalls, analyzing logs, monitoring traffic, and identifying intrusion attempts. Learners also explore enterprise-level solutions such as Snort, Suricata, pfSense, and Security Onion. This module prepares students to secure corporate networks effectively.

9. Cloud Security & Virtualization

As companies migrate to cloud platforms, cybersecurity professionals must understand cloud-specific risks and defenses. This module covers cloud service models (IaaS, PaaS, SaaS), deployment models (Public, Private, Hybrid), and cloud architectures from AWS, Azure, and Google Cloud. Students explore cloud vulnerabilities such as misconfigurations, IAM exploitation, insecure APIs, and data exposure. They learn access controls, identity management, data encryption, virtual machine security, container security, and Kubernetes security. Labs include setting up secure cloud environments and performing cloud security assessments.

10. Incident Response & Digital Forensics

When an attack occurs, cybersecurity teams must respond quickly. This module covers incident detection, triage, containment, eradication, recovery, and documentation. Students learn to analyze security alerts, investigate logs, detect anomalies, and gather digital evidence. The module also covers forensic tools, memory analysis, disk analysis, and chain-of-custody procedures. Through practical exercises, learners simulate real-world security breaches, perform root-cause analysis, and generate incident response reports. This module provides essential skills for roles such as SOC Analyst, Incident Responder, and Forensic Investigator.

11. Security Operations Center (SOC) & SIEM Tools

A Security Operations Center (SOC) is the heart of cybersecurity operations. Students learn how SOC teams monitor, analyze, and defend organizational networks. They explore SIEM tools such as Splunk, QRadar, ArcSight, ELK Stack, and Microsoft Sentinel. Training includes log management, alert tuning, threat intelligence integration, and monitoring dashboards. Labs focus on analyzing real-time alerts, detecting suspicious patterns, and creating incident workflows.
