Cybersecurity is no longer just an “enterprise problem”. Australian SMEs are increasingly being targeted by cybercriminals, from ransomware attacks to highly convincing phishing emails. The question is no longer if an attack will happen, but how prepared are you when it does?

A strong cybersecurity strategy is essential—and one often-overlooked piece of the puzzle is event logging. Many business owners aren’t fully aware of what event logging is, or why it matters.

Think of event logging as your digital paper trail. By recording activities across your IT systems, it helps you detect suspicious behaviour early and respond quickly. As your managed IT services partner, we help Australian businesses understand event logging, set it up properly, and use it to strengthen their overall security posture.

What Is Event Logging?

Event logging is the process of recording activities (or “events”) that occur across your IT systems. An event can include things like:

• Login and logout attempts
• File or data access
• Software installations
• Network activity
• Access being denied
• System or configuration changes
• And more

Each event is recorded with a timestamp, giving you a clear, chronological view of what’s happening across your systems. This ongoing visibility is crucial for identifying problems early and taking action before damage is done.

Why Is Event Logging So Important?

Effective event logging helps your business to:

• Detect suspicious activity by monitoring user behaviour and system events
• Respond faster to incidents by showing exactly what happened and when
• Meet compliance and regulatory requirements, particularly where accurate system records are required

Best Practices for Using Event Logging Effectively

Event logging delivers the most value when it’s done properly. Whether you’re starting from scratch or improving your existing setup, these best practices will help.

Log What Matters Most

Let’s be realistic—logging everything creates enormous amounts of data and quickly becomes unmanageable. Instead, focus on logging the events that matter most for security and compliance.

Key events to prioritise include:

• Logins and logouts
  Track who is accessing your systems and when, including failed login attempts, password resets, and new user accounts.
• Access to sensitive data
  Monitor who is accessing important files, databases, and business-critical systems.
• System changes
  Record software installs, configuration changes, updates, and patches. This helps identify unauthorised changes or potential backdoors.

Starting with these core areas keeps event logging practical and achievable for SMEs.

Centralise Your Logs

Trying to review logs stored across different systems is like searching for paperwork filed in multiple buildings. Centralising your logs makes a huge difference.

A Security Information and Event Management (SIEM) solution collects logs from all devices, servers, and applications into one location. This allows you to:

• Spot patterns across different systems
• Respond faster during an incident
• See the bigger picture of what’s happening across your network

Centralised logging is particularly valuable when investigating complex or multi-stage attacks.

Make Sure Logs Can’t Be Tampered With

Cybercriminals often try to erase or alter logs to cover their tracks. That’s why protecting your logs is critical.

Best practices include:

• Encrypting logs so only authorised users can read them
• Using WORM storage (Write Once, Read Many) to prevent modification or deletion
• Restricting access so only trusted personnel can view or manage logs

Tamper-proof logs ensure you retain an accurate record of events—even during a breach.

Set Clear Log Retention Policies

Storing logs forever isn’t practical, but deleting them too quickly can leave you exposed. A clear log retention policy helps strike the right balance.

Consider:

• Regulatory requirements that apply to your industry
• Business needs, such as how long logs are needed for investigations or audits
• Storage limits, so logging doesn’t impact system performance

Well-defined retention policies ensure you have the data you need, when you need it.

Review Logs Regularly

Event logging only works if someone is actively watching and responding. Logs should never be “set and forget”.

To stay on top of threats:

• Set up automated alerts for critical events like failed logins or unauthorised access
• Review logs regularly to spot trends or unusual behaviour
• Correlate events using your SIEM to uncover more advanced attack patterns

Automation helps, but human oversight remains essential.
