Certificate Course in Cybersecurity Foundation

Discover how the CIA triad—confidentiality, integrity, and availability—forms the foundation of cybersecurity, ensuring authorized access, data integrity, and continuous system availability.

Explore data sensitivity levels and apply a four-level scale from public to restricted to guide protection needs. Learn examples for each level: public, internal use only, confidential, and restricted.

Explore common malware types and how they spread: viruses attach to files, worms spread across networks, trojans disguise as legitimate software, ransomware encrypts data, spyware collects information, and rootkits hide.

Social engineering exploits human psychology to gain unauthorized access by manipulating trust, fear, and urgency, highlighting phishing, man-in-the-middle, pretexting, baiting, and deepfakes.

Explore four authentication methods: possession, knowledge, biometrics, and behavior, and learn how multi-factor authentication and authenticator apps strengthen online security.

Learn to create strong, unique passwords, avoid personal details, and use passphrases to defend against brute force attacks. Keep passwords private and rely on password managers to store them securely.

Contrast antivirus and anti-malware to see why signatures alone miss viruses and zero day threats. Anti-malware combines signature detection, heuristic analysis, behavioral monitoring, and sandboxing for broader protection.

Protect your files with data backup by following the 3-2-1 rule: three copies of data, two storage types, and one offsite location, spanning internal, external, and cloud storage.

Learn how data encryption turns information into ciphertext using symmetric and asymmetric keys, including public and private keys, and how hybrid encryption secures communications.

Firewalls act as guards for your network, inspecting all traffic and blocking anything suspicious based on predefined rules, with host-based, network-based, and cloud-based architectures.

Discover how intrusion detection systems monitor network traffic for suspicious activity and alert administrators. See how intrusion prevention systems build on IDS by automatically blocking detected attacks in real time.

Learn safe browsing by checking urls, using https everywhere, enabling phishing detection and ad blockers, and applying privacy settings, updates, and secure device practices.
