Cybersecurity Fundamentals & Threat Intelligence is a comprehensive course aimed at providing learners with a solid foundation in securing digital systems and understanding modern cyber threats. The course begins with an overview of the cybersecurity landscape, including types of threats (malware, phishing, ransomware, DDoS, insider threats) and key terms like CIA triad (Confidentiality, Integrity, Availability), threat vectors, vulnerabilities, and risk assessments. Learners explore the core principles of cybersecurity across networks, endpoints, applications, and cloud environments. The course introduces security frameworks such as NIST, ISO 27001, and CIS Controls. Emphasis is placed on building layered defense strategies using firewalls, antivirus software, intrusion detection systems, access control, and encryption. Learners are introduced to security operations center (SOC) workflows and SIEM platforms like Splunk and IBM QRadar. Threat intelligence is a major focus, teaching learners how to collect, analyze, and act upon indicators of compromise (IOCs), tactics, techniques, and procedures (TTPs), and threat actor profiles. Students explore the MITRE ATT&CK framework and sources of cyber threat feeds like STIX/TAXII and OSINT. Real-world case studies from recent data breaches and cyber incidents highlight practical response strategies. By the end, learners will understand foundational security principles, be able to assess threat landscapes, and apply threat intelligence to defend enterprise systems proactively.
