Network logs are detailed records of activity on your business's computer network. They track everything from who accessed which files to when devices connected or disconnected. If these logs aren't regularly monitored, it's like leaving your security cameras off—you miss warning signs of problems or attacks until it's too late.
Why Monitoring Network Logs Matters for Canadian SMBs
For small and mid-sized businesses in Canada, unmonitored network logs can lead to costly downtime, data breaches, or compliance issues. Without active review, unusual patterns—such as repeated failed login attempts or unexpected data transfers—go unnoticed. This increases the risk of cyberattacks, which can disrupt operations, cause data loss, and damage customer trust.
Moreover, Canadian privacy regulations and industry standards often require businesses to track and respond to network events. Failing to monitor logs can leave you unprepared for audits or investigations, potentially resulting in penalties or reputational harm.
A Typical Scenario
Consider a 50-person Canadian manufacturing company using Microsoft 365 tools and on-premises servers. One day, an employee's compromised password allows a hacker to access sensitive designs. Because network logs weren't monitored, the breach isn't detected for days. During that time, the attacker downloads confidential files and plants ransomware. Recovery takes weeks, costing the company lost production time and customer confidence.
A proactive IT partner would have set up automated alerts on network logs to flag unusual activity immediately. They would also regularly review logs to identify vulnerabilities and recommend timely security improvements, reducing the chance of such incidents.
Practical Checklist: What You Can Do
- Ask your IT provider: How often are network logs reviewed? Are there automated alerts for suspicious activity?
- Review service agreements: Confirm that network monitoring and incident response are included and clearly defined.
- Check access controls: Ensure only authorized staff can view or alter network logs.
- Verify backup procedures: Logs should be backed up securely to prevent tampering or loss.
- Request reports: Ask for regular summaries of network activity and any incidents detected.
- Train staff: Educate employees on recognizing signs of security issues and reporting them promptly.
Monitoring network logs is a foundational part of effective network management that helps prevent downtime, data breaches, and compliance problems. If you're unsure about your current setup, consider consulting a trusted managed IT provider or IT advisor who can assess your network monitoring practices and recommend improvements tailored to your business needs.
