Administrator training

Lesson 1 • Documentation and Change Logging

Introduces standards for recording configurations and changes. Establishes habits that prevent errors and support compliance throughout the course.

Lesson 2 • The Administrator Role Defined

Defines scope, authority, and accountability of an administrator. Anchors all subsequent technical learning to professional responsibility.

Lesson 3 • Safety, Ethics, and Compliance Basics

Covers ethical obligations, data handling principles, and regulatory awareness. Sets the professional conduct baseline for all administrative actions.

Lesson 4 • Administrative Interfaces and Toolsets

Surveys command-line, GUI, and web-based admin consoles. Builds tool fluency required before any hands-on configuration work.

Lesson 1 • Authentication Methods and Policies

Explains password policies, multi-factor authentication, and single sign-on. Directly reduces unauthorised access risk across managed systems.

Lesson 2 • Directory Services Administration

Manages centralised identity stores and directory hierarchies. Provides the backbone for consistent authentication across distributed environments.

Lesson 3 • User Account Lifecycle

Covers provisioning, modification, suspension, and deprovisioning of accounts. Connects identity governance to security and operational continuity.

Lesson 4 • Groups, Roles, and Permissions

Structures access control through groups and role-based assignments. Enables scalable permission management without individual account exceptions.

Lesson 1 • Application Whitelisting and Control

Restricts executable software to approved lists using policy-based controls. Prevents unauthorised software from running in managed environments.

Lesson 2 • Operating System Hardening

Applies security settings to OS components including services, ports, and registries. Reduces attack surface before any application is deployed.

Lesson 3 • Baseline Configuration Standards

Defines minimum secure configuration benchmarks for servers and endpoints. Establishes the reference point for all hardening activities in this chapter.

Lesson 4 • Group Policy and Configuration Management

Applies centralised policy objects to enforce settings across managed machines. Ensures consistent configuration at scale without manual intervention.

Lesson 1 • Network Monitoring and Diagnostics

Uses traffic analysis and diagnostic tools to identify and resolve issues. Connects network visibility to proactive performance and security management.

Lesson 2 • Firewall and Access Control Lists

Configures rule-based traffic filtering at network boundaries. Enforces segmentation and restricts unauthorised lateral movement.

Lesson 3 • VPN and Remote Access Configuration

Sets up encrypted tunnels for secure remote connectivity. Supports distributed workforces while maintaining network security posture.

Lesson 4 • IP Addressing and Subnetting

Covers IPv4 and IPv6 addressing, subnetting, and CIDR notation. Provides the numerical foundation for all network configuration tasks.

Lesson 1 • Storage Architecture and Provisioning

Explains DAS, NAS, and SAN storage models and provisioning workflows. Provides the structural knowledge needed before configuring any backup solution.

Lesson 2 • Backup Execution and Verification

Operates backup jobs, monitors completion, and validates data integrity. Confirms that backups are actually restorable before a crisis occurs.

Lesson 3 • RAID and Redundancy Configurations

Configures RAID levels to balance performance, capacity, and fault tolerance. Reduces single points of failure in storage infrastructure.

Lesson 4 • Disaster Recovery Planning and Execution

Builds and tests disaster recovery plans covering failover and data restoration. Prepares administrators to execute recovery under pressure with minimal data loss.

Lesson 1 • Incident Response Procedures

Executes the identify, contain, eradicate, and recover incident response cycle. Minimises damage and restores normal operations with documented evidence.

Lesson 2 • Threat Landscape and Risk Assessment

Surveys current attack vectors and maps them to organisational risk. Grounds all defensive actions in a prioritised understanding of real threats.

Lesson 3 • Security Information and Event Management

Configures log aggregation and correlation rules to surface suspicious activity. Provides the detection layer that triggers incident response workflows.

Lesson 4 • Vulnerability Scanning and Remediation

Runs automated scans, interprets findings, and drives remediation workflows. Closes exploitable gaps before attackers can use them.

Lesson 1 • Automating User and System Tasks

Applies scripting to automate account creation, reporting, and system checks. Converts high-frequency manual tasks into reliable scheduled operations.

Lesson 2 • Testing and Maintaining Automation

Validates scripts in test environments and maintains them through system changes. Ensures automation remains reliable and does not introduce new risks.

Lesson 3 • Configuration Management Tools

Uses declarative configuration tools to enforce desired system states at scale. Eliminates configuration drift across large fleets of managed systems.

Lesson 4 • API Integration and REST Calls

Interacts with system and service APIs to automate cross-platform workflows. Extends automation beyond local scripts to cloud and third-party services.

Lesson 1 • Key Performance Metrics and Baselines

Identifies CPU, memory, disk, and network metrics that define healthy operation. Establishes baselines that make anomalies detectable and actionable.

Lesson 2 • Performance Tuning and Optimisation

Applies targeted configuration changes to resolve bottlenecks and improve throughput. Closes the loop between monitoring findings and measurable performance gains.

Lesson 3 • Monitoring Tools and Dashboards

Deploys and configures monitoring platforms with alerting and visualisation. Gives administrators real-time and historical visibility into system behaviour.

Lesson 4 • Log Analysis and Trend Identification

Mines system and application logs to identify recurring issues and trends. Connects historical data to proactive problem resolution before user impact.
