Introduction to Cybersecurity

Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks. These cyberattacks are usually aimed at accessing, changing, or destroying sensitive information; extorting money from users; or interrupting normal business processes.

Common Threats

Understanding the threats is crucial. Some common threats include:

Malware (viruses, worms, ransomware)
Phishing
SQL Injection
Denial-of-Service (DoS) attacks

Secure Coding Practices

Writing secure code is essential to prevent vulnerabilities. Here's a simple example of input validation in Python:


def validate_input(user_input):
    if not user_input.isalnum():
        return "Invalid input"
    return user_input

Password Management

Use strong, unique passwords and consider a password manager. Enable two-factor authentication (2FA) whenever possible.

Network Security Basics

Proper network security is the foundation of cyber security. Firewalls, VPNs and intrusion detection systems are only a few of the tools used to secure networks.
