Subject: Computer science

Topic: Firewall

Time: 10 minutes

Class: 6

Name of School: ABC

No of students: 20

Specific Objective:

To introduce students to the concept of firewalls and their role in computer security.

Begin by asking the students if they've heard of the term "firewall" before. Encourage a brief discussion to gauge their existing knowledge.
Explain that today they'll be learning about an important aspect of computer security called a "firewall."

What is a Firewall? (2 minutes)
- Define a firewall as a security system that acts as a barrier between a trusted internal network and an untrusted external network, like the internet.
- Explain that firewalls monitor and control incoming and outgoing network traffic based on predetermined security rules.
How Does a Firewall Work? (2 minutes)
- Use simple analogies, like a security guard checking who enters a building, to explain how firewalls filter information coming into a network.
- Mention that firewalls can block or allow specific types of data based on rules set by administrators.
Types of Firewalls (2 minutes)
- Briefly mention different types of firewalls, such as software firewalls (installed on individual devices) and hardware firewalls (built into routers or network devices).
- Optionally, show illustrations or diagrams to visually explain how firewalls function.

Summarize the key points about firewalls: their purpose, how they work, and the different types.
Encourage students to think about how firewalls help keep their devices and information safe when they're online.

If time allows, conduct a simple activity where students can draw or describe scenarios where a firewall would be useful in protecting a network or a device.

Gauge understanding through questions: "Can anyone explain what a firewall does?" or "Why do you think firewalls are important for our devices?"
