Unit 1 Access Control Practical

🔐 AAA Authentication Configuration | Cisco Packet Tracer Practical | Pentest Ground Scenario In this practical lab, you will take on the role of Access Control Administrator for Pentest Ground, a New York–based security services organisation. Your responsibility is to strengthen router authentication by configuring AAA (Authentication, Authorisation and Accounting) using a local database within a simulated enterprise network. This step-by-step demonstration uses a pre-built Packet Tracer topology and focuses on implementing secure console authentication aligned with organisational security expectations. 🎯 Practical Objectives • Configure a local user account on Server2 • Enable and configure AAA authentication • Secure console access using the local database • Verify successful authentication from console and client devices • Validate network connectivity prior to configuration The lab is completed using network simulation software from Cisco. 🧪 Lab Tasks Covered in This Video Step 1 – Connectivity Testing ✔ Ping from PC-1 to PC-2 ✔ Ping from PC-2 to PC-3 ✔ Ping from PC-3 to PC-4 Ensures baseline network functionality before implementing authentication controls. Step 2 – Configure Local User on Server2 ✔ Create local username: Admin1 ✔ Configure secret password: admin1pa55 This establishes the credentials stored within the local database. Step 3 – Configure Local AAA for Console Access on R1 ✔ Enable AAA on R1 ✔ Configure AAA authentication for console login ✔ Set authentication to reference the local database This replaces standard line authentication with structured AAA controls to strengthen access management. Step 4 – Verify AAA Authentication ✔ Confirm User EXEC login ✔ Test username: Admin1 ✔ Test password: admin1pa55 ✔ Validate successful authentication from console and PC-1 Verification ensures authentication policies are correctly enforced and aligned with organisational security requirements. 📚 Skills Developed • Implementing AAA authentication • Securing router console access • Applying least privilege principles • Testing authentication controls • Validating configuration integrity • Evidence capture for assessment purposes 🛡 Why This Matters AAA strengthens access control by centralising authentication processes and ensuring only authorised administrators gain access to critical infrastructure. Proper configuration reduces the risk of unauthorised access, misconfiguration, and insider threat vulnerabilities. This practical aligns with Level 3 Networking and Cybersecurity learning outcomes relating to authentication implementation and secure network configuration.
