Cyber Security Fundamentals for Beginners

Learn to create strong and unique passwords. Use password managers, enable two-factor authentication, and follow best practices to protect your accounts.

Discover how password managers revolutionize online security by generating and storing strong, unique passwords, offering password strength analysis, cross-device syncing, and easy autofill.

Create strong, unique passwords using mixed case letters, numbers, and symbols. Store them securely with a password manager, avoid reusing passwords, and enable multi-factor authentication.

Recognize the importance of online privacy and learn to protect personal data, control your digital footprint, and strengthen defenses with VPNs, secure platforms, and privacy settings.

Learn to manage and protect your personal information online by being mindful of what you share, adjusting privacy settings, reviewing privacy policies, and practicing secure online shopping while avoiding phishing.

Take control of your digital privacy by configuring privacy settings and reviewing app permissions. Use privacy-oriented browsers and extensions, and encrypted messaging and email tools like Signal and Protonmail.

Identify and avoid email phishing attacks by spotting signs like generic greetings and suspicious links. Verify the sender, avoid attachments, and enable two-factor authentication.

Explore how email encryption safeguards confidentiality and integrity through symmetric and asymmetric methods, end-to-end services like Protonmail and Tutanota, encrypting attachments with digital signatures.

Learn best practices for safe messaging and file sharing, including end-to-end encrypted apps like Signal, WhatsApp, and Telegram, plus identity verification, file encryption, password-protected sharing, and phishing awareness.

Explore the fundamentals of cryptography, including encryption, decryption, keys, and algorithms, and see how symmetric and asymmetric methods secure confidentiality, integrity, and authenticity in https and digital signatures.

Explore symmetric cryptography and key management, comparing aes and des and modes like ecb, cbc, ctr, gcm, and outline secure key generation, storage, and exchange.

Explore how public key cryptography enables secure, verifiable communication using public and private keys, rsa and elliptic curve cryptography, and digital signatures with hash-based verification and certificates.

Identify and avoid malicious websites by spotting phishing, malware distribution sites, and fake online stores, using red flags like suspicious URLs, poor design, and unexpected pop ups.

Explore browser security features like https with the padlock, ssl tls encryption, pop-up blockers, and privacy settings to defend against phishing and malware.

Explore the treacherous world of malware and its impact, including viruses, worms, trojans, ransomware, spyware, and adware, and learn defenses like antivirus software, updates, firewalls, safe browsing, and backups.

Explore common malware types—viruses, worms, Trojans, ransomware, spyware, adware, and keyloggers—and learn how they spread, steal data, or disrupt systems, with practical prevention tips.

Guard against malware by enabling real-time antivirus scans, avoiding phishing, practicing safe online behavior, and updating your system from reputable sources to prevent and remove infections.

Explore common cyber threats like brute force, DDoS, phishing, and social engineering, and learn practical defenses to stay safe online.

Identify how brute force, DDoS, phishing, and social engineering threats threaten security and digital wellbeing. Implement strong passwords, 2FA, account lockout policies, rate limiting, monitoring, and incident response to defend.

Update your software and security tools regularly to patch vulnerabilities. Practice strong password management, beware suspicious emails, enable two-factor authentication, and back up data to deter cyber attacks.
