What is security monitoring?
Security monitoring is the process of collecting and reviewing events that may show suspicious activity, policy violations, system failures, or attacks.
Important logs to collect
Start with identity sign-ins, administrator actions, endpoint alerts, firewall events, VPN logins, email security alerts, DNS logs, and critical server events.
What to look for
Watch for impossible travel, repeated login failures, new admin accounts, disabled security tools, suspicious mailbox rules, unusual outbound traffic, and access from unexpected countries.
Make alerts actionable
Too many alerts create fatigue. Start with a small number of high-quality alerts that your team can actually investigate.
Create a weekly review habit
Even without a full SIEM, teams can review important dashboards weekly and document findings, false positives, and follow-up actions.
Practical checklist
- Review sign-in logs
- Check admin changes
- Monitor endpoint alerts
- Review VPN access
- Document findings
