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 security system used to protect computers, networks, and devices from unauthorized access and cyber threats. It acts like a digital barrier between a trusted internal network (like your home or business network) and untrusted external networks (like the internet).

What does a firewall do?

A firewall monitors and controls incoming and outgoing network traffic based on a set of security rules. Its main job is to block harmful or suspicious data while allowing safe data to pass through.

Types of firewalls:

1. Software Firewall: Installed on individual computers or devices. It protects only that specific device.

2. Hardware Firewall: A physical device that protects an entire network. Often used in businesses.

3. Cloud/Network-based Firewall: Used in larger organizations or online systems, often integrated into cloud platforms.

What can a firewall protect against?

• Hackers trying to access your system

• Viruses and malware coming through the internet

• Unwanted programs connecting to the internet without your knowledge

• Data leaks or unauthorized data leaving your network

Example:

If a hacker tries to send malicious data to your computer, the firewall will inspect the data and block it if it looks dangerous or doesn’t meet the security rules.

In simple terms:

A firewall is like a security guard for your digital world. It checks every piece of data that tries to enter or leave your system and only lets through what’s safe. It helps keep your information private and your devices secure.
