Build your cybersecurity knowledge from the ground up. From basics to advanced concepts, learn how to protect yourself online.
Use this checklist to ensure you're following best practices for personal digital security. Check each item as you implement it.
Test your phishing detection skills with interactive email scenarios. Identify safe vs. suspicious emails to earn your detective badge!
Practice real-world attack and defense scenarios in a safe, simulated environment. Learn API security, IoT vulnerabilities, and network defense.
Learn to identify and exploit common API vulnerabilities: broken authentication, excessive data exposure, lack of rate limiting, and injection attacks.
Discover IoT vulnerabilities: insecure firmware, default credentials, unencrypted communications, and lack of physical security.
Practice detecting and responding to network attacks: port scanning, DDoS attacks, man-in-the-middle, and lateral movement.
Identify and exploit cloud misconfigurations: open S3 buckets, overly permissive IAM policies, exposed secrets, and insecure APIs.
Master OWASP Top 10 vulnerabilities: SQL injection, XSS, CSRF, insecure deserialization, and broken access control.
Respond to a live ransomware attack: contain the threat, preserve evidence, analyze logs, and recover systems.
A strong password is your first line of defense. Learn how to create passwords that are hard to crack but easy to remember with passphrase techniques.
2FA adds an extra layer of security by requiring a second verification method beyond just your password. Even if someone has your password, they can't access your account without the second factor.
Phishing emails are designed to look legitimate but contain malicious links or requests. Learn the telltale signs to stay safe.
Public WiFi networks are convenient but risky. Attackers can intercept unencrypted traffic. Learn how to stay safe when using public internet.
Regularly audit your online accounts to ensure they're secure. Learn how to check if your accounts have been compromised.
Regular backups protect you against ransomware and data loss. Learn the 3-2-1 backup strategy recommended by security experts.
Always validate and sanitize user input. Never trust data coming from users, APIs, or external sources. Implement strict validation rules.
Implement proper authentication mechanisms and enforce principle of least privilege. Users should only have access to what they need.
Encrypt sensitive data both in transit and at rest. Use strong encryption algorithms and secure key management practices.
Implement proper error handling without revealing sensitive information. Generic error messages prevent information disclosure attacks.
Security should be built into your development process. Regular code reviews and security testing catch vulnerabilities early.
Keep track of your dependencies and update them regularly. Vulnerable third-party libraries are a common attack vector.
Firewalls monitor and control network traffic based on security rules. They form a barrier between trusted internal networks and untrusted external networks.
VPNs create encrypted tunnels for your internet traffic, protecting it from eavesdropping and masking your IP address on public networks.
SSL/TLS encrypts data between your browser and websites. Look for HTTPS and the padlock icon to ensure secure connections.
Dividing networks into segments limits the spread of breaches. If one segment is compromised, others remain protected.
IDS monitors network traffic for suspicious patterns and alerts administrators to potential attacks.
DNS (Domain Name System) translates URLs to IP addresses. Protect it to prevent redirects to malicious sites and data exfiltration.
Symmetric Encryption: Uses one key for both encryption and decryption. Fast but requires secure key sharing.
Asymmetric Encryption: Uses public and private keys. Public key encrypts, private key decrypts. Enables secure key exchange and digital signatures.
In Practice: Often combined - asymmetric encryption secures key exchange, then symmetric encryption for data.
Advanced Encryption Standard is widely used for securing data at rest. AES-256 is considered secure against brute force attacks for many years.
RSA is the most common asymmetric algorithm used for key exchange and digital signatures in SSL/TLS and many other applications.
Hashing creates unique fingerprints of data. It's one-way (can't reverse) and used to verify data hasn't been modified.
