Firewalls are like the security guards of a network—they monitor and control incoming and outgoing traffic based on predefined security rules. Their main job is to protect your network from unauthorized access, cyberattacks, and data breaches.

Common methods hackers use to steal data include:

1. Phishing – Tricking users into revealing sensitive information through fake emails, websites, or messages that appear legitimate.

2. Malware – Installing malicious software (like viruses, trojans, or spyware) that secretly collects data or gives attackers control over systems.

3. Man-in-the-Middle (MitM) Attacks – Intercepting data transmitted between two parties, often on unsecured public Wi-Fi networks.

4. SQL Injection – Exploiting poorly secured databases by inserting malicious code into input fields to access stored information.

5. Brute Force Attacks – Guessing passwords through automated tools that try many combinations until they succeed.

6. Credential Stuffing – Using stolen username-password pairs from previous breaches to log into other accounts.

7. Social Engineering – Manipulating people into giving away confidential information by exploiting trust or authority.

8. Exploiting Software Vulnerabilities – Taking advantage of unpatched security flaws in applications or operating systems.

💡 Many of these methods succeed because of weak passwords, outdated software, or careless clicking, which means strong security habits and timely updates are key to prevention.
