System Hardening (A+1202)

By completing this lab, you will be able to:

Security Policy Implementation

• Configure comprehensive password policies and enforcement mechanisms 

• Implement account lockout policies for failed authentication attempts 

• Manage user account permissions and privilege restrictions 

• Configure screen lock settings for unauthorized access prevention

System Configuration Hardening

• Configure and manage Windows Firewall settings 

• Disable unnecessary services and minimize attack surface 

• Update operating systems and applications systematically 

• Implement data encryption for information protection

Access Control Management

• Establish principle of least privilege for user accounts 

• Configure automatic update mechanisms for security patches

• Manage service accounts and system-level permissions

Overview

This hands-on lab provides comprehensive practice in implementing system hardening techniques—critical skills for IT professionals and CompTIA A+ certification candidates. Covering objectives from the 220-1202 exam, you'll develop proficiency in securing Windows systems through systematic configuration of security controls, user account management, service hardening, and data protection measures.

Through guided exercises, you'll master essential hardening practices including password policy enforcement, account lockout configuration, firewall management, service minimization, permission control, screen lock implementation, data encryption, and automated update configuration. These skills are fundamental for creating secure computing environments that resist both external attacks and internal security breaches while maintaining system functionality and user productivity.
