About This Course

Enroll in our CyberSec First Responder (CFR-310) Course to sharpen your instincts, respond like an expert, and lead the charge when cyber threats hit.

In this course, assess real-world risks, decode the threat landscape, and dive deep into system and network attacks (social engineering, malware, DoS, cloud threats, you name it). Learn how attackers move, hide, and exfiltrate data. From there, flip the script with vulnerability management, penetration testing, and forensic investigations.

With hands-on labs, you’ll train to take control of SIEM tools, threat modeling, log analysis, and incident response scenarios. From identifying threats to securing evidence, this course equips you with everything to pass the CFR-310 exam and level up your cyber defense skills.

Skills You’ll Get

  • Threat Detection & Analysis: Identify, classify, and analyze evolving cyber threats using real-world threat modeling and reconnaissance techniques.
  • Risk Assessment & Mitigation: Assess information security risks and apply effective strategies to reduce vulnerabilities across systems.
  • Incident Response & Recovery: Develop the skills to contain, respond to, and recover from security breaches using proven incident handling frameworks.
  • Vulnerability Management: Conduct vulnerability scans, analyze results, and strengthen your organization's defenses.
  • Digital Forensics & Investigation: Master the art of investigating cyber incidents: collecting evidence, analyzing compromised systems, and documenting findings.
  • Security Intelligence & Log Analysis: Use tools like SIEM and network log analyzers to monitor environments, detect anomalies, and generate actionable security insights.
