Authentication and role-based access control are the focus of this Grade 11 Computer Science worksheet for Cybersecurity. Students examine how secure systems first verify identity and then control what authenticated users are allowed to see or do. They also distinguish roles from permissions and compare password-only login with multi-factor authentication. :contentReference[oaicite:0]{index=0}

Separate identity verification from authorization

The resource helps students understand an important security distinction. Authentication answers whether a user is really who they claim to be before access is granted. Access control applies after successful login and limits available actions according to defined rules.

Students then explore how permissions and roles work together. A permission represents a specific allowed action, such as reading a file or changing a setting. A role groups permissions so they can be assigned efficiently to users with similar responsibilities. This makes role-based access control easier to connect to real systems such as schools, workplaces, and shared applications.

Security concepts appear in varied practice

• A dialogue-based question introduces authentication and access control in context
• Matching practice connects security terms with their functions
• A cloze passage reinforces authentication, access control, roles, permissions, multi-factor authentication, and passwords
• A diagram-labeling activity supports visual understanding of the access process
• An informational reading passage explains identity checks, permissions, roles, and stronger login protection
• Multiple-choice questions ask students to reason about successful login, blocked actions, role assignments, permissions, and MFA
• True-or-false statements check understanding of authentication, role-based access control, and multi-factor login
• Short-answer questions require students to explain differences between key security concepts
• An extended response applies authentication and access control to a school grading system

Apply access rules to a realistic scenario

The extended task asks students to design security for a school system where teachers can grade assignments while students can view only their own grades. Students must explain how authentication verifies users, how roles or permissions limit actions, and how multi-factor authentication could provide another layer of account protection.

This worksheet can be used for guided Cybersecurity practice, independent work, homework, review, or conceptual assessment. A separate Teacher Guide PDF includes learning objectives, teaching tips, discussion questions, and common mistakes to support lesson preparation and classroom discussion.
