Section Title Primary information Description and Notes Suggested resources
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 begins to explore how servers are made safe and secure for users and how their roles and responsibilities are determined and controlled.  Some investigation of permissions should be undertaken. The lesson will look at how system servers deal with users permissions and access rights.

Lesson Links: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39

Key words role, responsibility, permission, password, authentication, read/write These words need to be reinforced throughout the series of lessons  
Assessment Identify key factors that can affect server and network performance Evidence here will be the students showing a basic understanding of the main roles and responsibilities in a basic network set-up. Explore different servers and services, if possible, showing some of the systems in operation.  Look at the roles and permissions of different users and why there is a need for something like an administrator.
Key Questions Some questions to get learners thinking about the topics Some questions and examples will get the students thinking about what network authentication and roles are required and why. What is wrong with all users being an administrator on the school network?  Can't you trust everyone?
Learning Objectives
  • To understand and describe the key roles and permissions on a network
  • To explain, with examples, how servers control access
  • To understand how servers function and describe security concerns
  • To understand what features are used to control and regulate access

Students will need to understand some of the management functions of servers and how they control who is allowed to do what on a network.  They should also be comfortable with explaining roles and basic authentication methods on networks.

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
  • introduction to server user management
  • detailed look at the main management tools
  • Students can break into groups and work on some basics of server roles and permissions
  • Class discussion and evaluation of the wider uses of server roles
  • Summarize the key points and reinforce the importance of security

In this lesson we need to discuss how servers control access to network resources and why this is.  Students should appreciate what the different roles are and why admins have to be the highest level.

There is no need to go into great details, but it would be useful to explore some of the management functions based on roles and permissions.

Using a Virtual Machine is an easy way to play with server technology without messing up your own network. 

 
Lesson Structure Possible structure
  1. investigate server control software
  2. show students some more examples of roles and permissions
  3. group work to work on some of their own views and examples
  4. discuss what they have learned and what they can apply
  5. volunteers to share their work and explain how they came to their opinions
  6. highlight next week's focus and issue homework

Key graphic

Students should be clear about the permissions on a network, in particular read and write.  In most cases, they will be allowed to read and write to their own specified home area, but ony allowed to read the teachers.

The control of these actions is through policies that determine their role and therefore what they are allowed to do and where.  These roles are controlled by the system administrator who has th ability to do all other roles.

Homework Get students to blog about what their roles and responsibilities should be on a school network and why. Students can vary their homework depending on their level of understanding. Get students to document their experience on their portfolio system for assessment
