Event Logging: Your

Event Logging:

Your First Line of Defence Against Cyber Threats

Introduction
Imagine someone walking into your office after hours. If there are no cameras or logs, would you ever know? The same applies to your IT systems. Without event logging, malicious activities often go unnoticed until it’s too late.

As part of Cyber Security Awareness Month, ASD and the ACSC are highlighting the importance of event logging in building a cyber safe culture. At Squaretech, we couldn’t agree more — logging is the foundation of cyber resilience.

What Is Event Logging?
Event logging is the process of recording activity across your systems, applications, and networks. Think of it as a “black box recorder” for your IT environment.

Logs can capture:

• Failed login attempts

• File changes or deletions

• Suspicious network traffic

• System errors or unusual activity

Why It Matters
Cybercriminals increasingly use stealthy methods — like “living off the land” attacks — where they use legitimate tools to blend in. Without logging, these actions look like everyday activity. With logging, you have a paper trail to detect, investigate, and respond.

Best Practices for Event Logging

• Log broadly: Cover endpoints, servers, cloud apps, and firewalls

• Centralise logs: Use a Security Information and Event Management (SIEM) tool

• Keep logs long enough: Retain them for compliance and forensic analysis

• Monitor actively: Don’t just collect logs — review them, or automate alerts
