Social engineering in security refers to the manipulation of people into performing actions or divulging confidential information, often by exploiting human emotions such as trust, fear, or urgency. Instead of attacking a computer system directly, social engineering targets the human element of security, making it one of the most effective and dangerous forms of cyberattack.

A firewall is a cybersecurity tool that helps protect a computer or network by controlling the flow of incoming and outgoing traffic. It acts like a security barrier between a trusted internal network and untrusted external networks, such as the internet.

What a Firewall Does:

• Monitors Traffic: It inspects data coming in and out of the network.

• Blocks Threats: If the traffic does not meet predefined security rules, the firewall can block it.

• Prevents Unauthorized Access: It stops hackers or malicious software from gaining access to your system.

• Allows Safe Communication: Only trusted, safe connections and data are allowed through.

Types of Firewalls:

1. Hardware Firewall: A physical device that protects an entire network (commonly used in businesses).

2. Software Firewall: Installed on individual devices like laptops or desktops.

3. Network Firewall: Protects a network by filtering traffic based on IP addresses, protocols, ports, etc.

4. Application Firewall: Focuses on controlling input, output, and access to specific applications.

Why It’s Important:

Without a firewall, your system is vulnerable to threats like viruses, worms, unauthorized access, and data theft. Firewalls are a critical first line of defense in any cybersecurity strategy.
