4.1 Documentation & Support Systems: The Organizational Pillars

Effective IT operations rely on robust documentation and well-managed support systems. These tools and practices ensure consistency, efficiency, and knowledge retention.

Ticketing Systems

The heart of IT support, tracking issues from report to resolution. Example: osTicket.

  • User & Device Information: Essential for context.
  • Description of Problems, Categories, Severity, Escalation Levels: For prioritization and routing.
  • Clear, Concise Written Communication:
    • Problem Description: Accurate initial report.
    • Progress Notes: Regular updates on actions taken.
    • Problem Resolution: Detailed steps to fix and outcome.

Asset Management

Tracking IT assets throughout their lifecycle. Learn about ITIL's take on IT Service Management which includes asset management.

  • Inventory Lists & Database System: What you have and where it is.
  • Asset Tags and IDs: Unique identification.
  • Procurement Life Cycle: From purchase to disposal.
  • Warranty and Licensing: Tracking for compliance and support.
  • Assigned Users: Accountability.

Types of Documents

  • Acceptable Use Policy (AUP): Defines how IT resources can be used. See an example policy template from SANS.
  • Network Topology Diagram: Visual map of the network. Tools like Lucidchart can help.
  • Regulatory Compliance Requirements & Splash Screens: Adhering to laws like GDPR, HIPAA, PCI DSS. Splash screens often display warnings or AUP summaries.

4.2 Explain Basic Change Management Best Practices: Navigating Transitions

Change is inevitable in IT. Proper change management minimizes disruption and risk. Explore ITIL's perspective on Change Management.

Documented Business Processes

  • Rollback Plan: How to revert if the change fails.
  • Sandbox Testing: Testing changes in an isolated environment.
  • Responsible Staff Member: Clear ownership of the change.

Change Management Process

  • Purpose & Scope of the Change: Why and what is changing.
  • Date and Time: Scheduled implementation.
  • Affected Systems/Impact: What will be affected and how.
  • Risk Analysis (including Risk Level): Assessing potential negative outcomes. See a basic guide on IT risk assessment from NIST.

  • End-User Acceptance: Confirmation from users that the change is successful.

4.3 Implement Workstation Backup and Recovery Methods: The Safety Net

Data loss can be catastrophic. Robust backup and recovery strategies are essential for workstations.

Backup and Recovery Types

Different methods for different needs. Backblaze explains backup types well.

  • Full: Backs up all selected data. Slowest to backup, fastest to restore.
  • Incremental: Backs up data changed since the *last backup* (full or incremental). Fast to backup, potentially slow to restore (needs last full + all incrementals).
  • Differential: Backs up data changed since the *last full backup*. Faster than full, slower than incremental. Restore needs last full + last differential.
  • Synthetic: Creates a new full backup by combining a previous full backup with subsequent incremental/differential backups on the backup server, not the client.

Backup Testing & Rotation

  • Backup Testing Frequency: Regularly test restores to ensure backups are viable.
  • Backup Rotation Schemes:
    • On-site vs. Off-site: Local copies for quick recovery, remote copies for disaster recovery.
    • Grandfather-Father-Son (GFS): Common rotation for daily, weekly, monthly backups.
    • 3-2-1 Backup Rule: At least 3 copies of data, on 2 different media types, with 1 copy off-site. Learn more about the 3-2-1 rule from Veeam.

  • Lifting Techniques: Prevent back injuries.
  • Electrical Fire Safety: Know extinguisher types (Class C for electrical). See info from OSHA on fire extinguishers.
  • Safety Goggles & Air Filtration Mask: Protect eyes and lungs.

4.5 Environmental Impacts and Local Environmental Controls: IT's Green Footprint

Responsible IT includes managing environmental factors and proper disposal.

Handling and Disposal

  • Material Safety Data Sheet (MSDS)/Safety Data Sheet (SDS): Provides info on hazardous materials. See OSHA's page on SDS.
  • Proper Disposal:
    • Batteries: EPA guidelines / Call2Recycle.
    • Toner: Manufacturer take-back programs or specialized recyclers.
    • Other Devices/Assets: E-waste recycling programs.

Environmental Controls

  • Temperature, Humidity, Ventilation: Maintain optimal conditions for equipment.
  • Location/Equipment Placement: Ensure proper airflow.
  • Dust Cleanup: Use compressed air/vacuums designed for electronics.

  • Installation of applications, automated backups.
  • Gathering information/data, initiating updates.

Other Considerations When Using Scripts

  • Risk of unintentionally introducing malware (if script source is untrusted).
  • Inadvertently changing system settings if not carefully written/tested.
  • Potential for browser or system crashes due to mishandling of resources.

4.9 Use Remote Access Technologies: Connecting from Afar

Remote access tools are indispensable for modern IT support, allowing technicians to assist users and manage systems without being physically present.

Common Methods/Tools

  • RDP (Remote Desktop Protocol): Built into Windows for graphical remote control. Microsoft RDP Info. Requires port 3389 to be open/forwarded.
