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. A firewall is a vital security device or software sitting between a trusted internal network and an untrusted external network, such as the internet. Its main function is to monitor and control all incoming and outgoing network traffic, ensuring on

Hackers employ various techniques to breach systems, often exploiting human behavior and software vulnerabilities. Some of the most common methods include:

• Phishing: This is a form of social engineering where attackers impersonate a trusted source (like a bank, a boss, or a well-known company) through fraudulent emails, text messages, or phone calls. They trick victims into revealing sensitive information, such as passwords or credit card numbers, or into downloading malicious attachments.

• Malware: This is a broad term for malicious software designed to disrupt, damage, or gain unauthorized access to a computer system. Common types of malware include:

  • Viruses: Attach themselves to legitimate programs and spread when the user runs the infected file.

  • Trojans: Disguise themselves as harmless or useful software but contain a malicious payload that activates once the user installs them.

  • Ransomware: Encrypts a victim's files, demanding a ransom to restore access.

• Brute-Force and Credential Stuffing Attacks: These are automated attacks that attempt to guess login credentials.

  • Brute-force attacks systematically try every possible password combination until the correct one is found.

  • Credential stuffing uses lists of usernames and passwords stolen from previous data breaches to try to log in to other websites. This is highly effective because many people reuse the same credentials across multiple services.

• Exploiting Software Vulnerabilities: Hackers constantly search for and exploit flaws or "bugs" in software, operating systems, or web applications. If a system is not regularly updated with security patches, it can be vulnerable to attacks that take advantage of these weaknesses.

• Man-in-the-Middle (MITM) Attacks: In an MITM attack, the hacker secretly intercepts and relays communications between two parties who believe they are communicating directly. This allows the attacker to steal or alter data being transmitted, often over unsecured Wi-Fi networks.
