Cybersecurity Basics: Protecting Your Applications & Data
In an increasingly connected world, cybersecurity is paramount. This module introduces fundamental cybersecurity concepts for developers, covering common vulnerabilities, secure coding practices, and strategies to protect your applications and user data from potential threats.
1. Introduction to Cybersecurity for Developers
Understand the critical importance of cybersecurity in modern software development. This section outlines why developers need to prioritize security, introduces common types of cyber threats and attacks, and gives an overview of the OWASP Top 10, a standard reference for the most critical web application security risks.
Common Cybersecurity Threats
- **Data Breaches:** Unauthorized access to sensitive information.
- **Malware:** Malicious software (viruses, ransomware).
- **Phishing:** Deceptive attempts to obtain sensitive information.
- **DDoS Attacks:** Overwhelming a system with traffic to disrupt service.
2. Web Application Security (OWASP Top 10)
Delve into specific web application vulnerabilities highlighted by the OWASP Top 10. Learn about Injection flaws (SQL Injection), Cross-Site Scripting (XSS), Cross-Site Request Forgery (CSRF), broken authentication, security misconfigurations, and how attackers exploit them.
3. Secure Coding Practices
Implement secure coding practices to build resilient applications. This section covers essential techniques such as input validation and sanitization, secure password storage (hashing and salting), principle of least privilege, and using secure communication protocols (HTTPS).
Code Example: Secure Password Hashing (Conceptual)
// Example using Node.js with bcrypt (conceptual)
const bcrypt = require('bcrypt');
async function hashPassword(password) {
const saltRounds = 10;
const hashedPassword = await bcrypt.hash(password, saltRounds);
return hashedPassword;
}
async function verifyPassword(password, hashedPassword) {
const isMatch = await bcrypt.compare(password, hashedPassword);
return isMatch;
}
// Usage (conceptual)
// const userPassword = "mySecretPassword123";
// const hashed = await hashPassword(userPassword);
// const isValid = await verifyPassword(userPassword, hashed);
// console.log(isValid); // true
4. Data Protection & Privacy
Understand how to protect sensitive data and ensure user privacy. This section covers encryption basics (data at rest vs. in transit), anonymization techniques, and an overview of major data privacy regulations like GDPR (General Data Protection Regulation) and CCPA (California Consumer Privacy Act).
Module Summary
