# Cybersecurity Threats and Safe Internet Practices

## Cybersecurity Threats
- **Phishing**
A deceptive attack where cybercriminals impersonate legitimate entities to trick victims into revealing sensitive information.
- **Denial-of-Service (DoS) attack**
A cyber attack that overwhelms a system's resources, making it unable to respond to legitimate service requests.
- **Distributed denial-of-service (DDoS) attack**
A similar attack to a DoS attack, but initiated by many malware-infected host machines.
- **SQL injection**
An attack that exploits vulnerabilities in databases by injecting malicious code into user inputs.
- **Cross-Site Scripting (XSS)**
An attack that involves injecting malicious code into a website, but the code only runs in the user's browser.
- **Ransomware**
A malicious form of software that encrypts a victim's files or locks them out of their computer system, demanding a ransom payment in exchange.

## Safe Internet and Device Usage
- **Verify Website Security**
- Look for HTTPS in the URL.
- Avoid clicking on pop-ups or ads promising free products or rewards.
- **Use Strong Passwords**
- Make passwords at least 8 characters long with a mix of letters, numbers, and symbols.
- Avoid using common words or phrases.
- Use a password manager to store and generate secure passwords.
- **Enable Multi-Factor Authentication (MFA)**
- Add an extra layer of protection to your accounts by requiring a second form of verification (e.g., a code sent to your phone).
