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.
1. Phishing
Fake emails or messages trick users into revealing sensitive data like passwords or credit card numbers. Often appears to come from trusted sources.
2. Malware
Short for “malicious software,” it includes viruses, worms, spyware, and ransomware. It can damage systems, steal data, or take control of devices.
3. Ransomware
A form of malware that encrypts data and demands payment (ransom) for its release. It's highly disruptive and often targets organizations.
4. Man-in-the-Middle (MitM) Attacks
An attacker secretly intercepts and possibly alters communication between two parties. Often happens over unsecured networks.
5. Denial-of-Service (DoS) and Distributed DoS (DDoS)
Floods a network or server with traffic to overwhelm and crash it, denying access to users.
6. SQL Injection
Attackers insert malicious SQL code into web applications to access or manipulate databases.
7. Zero-Day Exploits
Targets vulnerabilities in software that are unknown to the vendor and have no patch, making them highly dangerous.
8. Credential Stuffing
Uses leaked username/password combinations from past breaches to gain unauthorized access to user accounts.
9. Brute Force Attacks
Hackers try many password combinations until the correct one is found.
10. Insider Threats
Attacks or data breaches caused by employees or contractors with access to internal systems.
Conclusion:
Cyber attacks vary in method and impact, but all aim to steal, disrupt, or damage. Understanding these threats is key to building strong security defenses.
