|Lesson Length||The expected lesson length will be approximately one hour||
Some variation possible.
Assessment Level 1
|Students||The lesson is suitable for KS3 and KS4 students||Since this is a new specification, the lesson is suitable for Year 7 to 9 students and differentiated by outcome|
|Overall Focus||This lesson takes a brief look at firewalls and what they do.||The lesson will look at the basic way that firewalls work and what they are expected to do in a network system.|
|Key words||firewall, ports, scanning, filtering,||These words need to be reinforced throughout the series of lessons|
|Assessment||identify a firewall and explain its purpose||Evidence here will be the students showing a basic understanding of what a firewall does.||Investigate the school firewall in operation|
|Key Questions||Some questions to get learners thinking about the topics||Some questions and examples will get the students thinking about what the main threats to a computer network are and what a firewall does to stop or minimise these.||Who wants to come in to our network and why?|
Students should have a basic idea of the need to protect networks from intrusion. Their school should have a decent firewall and even their home broadband should have some type of firewall, but what does it do and how does it do it?
Students should link the firewall to the protocols they looked at earlier. It is no good a firewall blocking email going in and out etc, so needs to allow smtp protocol through port 25.
|If you are using the Learning Machine learning system, students can add their comments and material to this site as evidence of their growing understanding. The site, if used consistently, will show progression via charts of activity and outcomes.|
|Teaching and Learning Elements||
In this lesson we need to explore the main types of firewall as well as look at the strengths and weaknesses.
|One useful tool for looking at the need for a firewall is something like Wireshark. This software will show students who is trying to get in o their computer and what method they are trying. As long as your broadband is switched on, someone is attacking it.|
|Lesson Structure||Possible structure||
|Homework||Get students to blog about firewalls and the dangers of hackers.||Students can vary their homework depending on their level of understanding.||Get students to document their experience on their portfolio system for assessment|
